On 1963 Nov 10/11 at UT 23:35-00:32 Kopal (Pic du Midi, France, 24" refractor) observed a TLP in Kepler. Cameron says that the date maybe a misprint, should be 11/1/63? - sunset terminator at 25W and Copernicus in dark. The Cameron 1978 catalog ID=782 and weight=0. The ALPO/BAA weight=1.
On 1989 Jun 28 at UT 08:39-09:00 D. Darling (Sun Praire, WI, USA, 3" refractor, x36) discovered that at this time Mons La Hire was the brightest feature on the Moon. LaPrice was also very bright. Cameron quotes that Darling recorded that LaHire had a brightness of 7.0 and LaPlace=7.5. Darling did not think that this was a TLP. The Cameron 2006 catalog ID=369 and weight=0. The ALPO/BAA weight=1.

Southern cusp obseved by H.Hill (UK) on 1985 Sep 12 UT0435-0455. Solar Selenographic colongitude=241.3. Observer saw an extremely attenuated cusp extending well beyonf the Moon's prime meridian. There were also dusky ill-defined stips along the Earthlit limb nearby. Note that this is almost certianly not a TLP but is worth checking out if the libration and solar colongitude is similar, just to verify that this is what the Moon normally looks like. ALPO/BAA weight=1.
On 1988 Apr 19 at UT 01:15-04:00 J. Horne (Steadman, NC, USA, 8" reflector, S=4/10) took photographs of the Moon's Earthshine (appeared in the Aug 1988 Sky and telescope magazine). Aristarchus was bright. In addition several members of the Madison Astronomical Society also found the crater to be bright and one of them saw streaks and flashes from the crater. Manske (8" reflector, x97, + binoculars, S=E) found the crater to be "abnornormally bright" where as other craters in Earthshine were just normal. Fryback's (Madison, WI, USA, 8" reflector, S=VG) photographs confirm that the crater was very bright - the Moon was only 4deg in altitude though. The Camweron 2006 catalog ID=325 and the weight="confirmed". the ALPO/BAA weight=3.

On 1788 May 08/09 at UT 20:00-01:00? Mechain (France) observed bright spots near Aristarchus. This was confirmed by Schroter and Bode (Lilienthal, Germany, 7" reflector and refractor). The Cameron 1978 catalog weight=5 and ID=46 & 47. The ALPO/BAA weight=4.
On 1990 Mar 29 at UT 19:00 L. Todd (England?) observed that Aristarchus in Earthshine was very clearly seen and appeared to blink occasionally. Foley (Kent, UK) also notcied variations in Aristarchus. The Cameron 2006 catalog ID = 396 and the weight=1. The ALPO/BAA weight=1.
On 1992 Apr 06 at UT00:45-02:03 G. Johnson (Swanton, MD, USA, 3.5" refractor, x36) observed Aristarchus in Earthsine, but at a higher magnification is appeared as a diffuse star. However the crater was not seen later. D. Darling (Sun Praire, WI, USA, 3" refractor), D. Weier and F. Graham (Pittsburgh, PA, USA, 7" reflector, photographs), observing at 01:24UT could not see the crater. The cameron 2006 catalog ID=443 and the weight=0. The ALPO/BAA weight=1.
On 1988 Apr 20 at UT02:06-03:00 D. Fryback (Madison, WI, USA, 8" reflector, S=3-4) commented that Aristarchus crater looked like a "city from high above "glowing under a cloud". Spain (Fairfield, KY, USA, 8" reflector, S=VG) detected a streak and flashes but reports that the crater was not "glowing", though it was the brightest feature in the Earthshine, but Kepler and Copernicus were bright too. Aristarchus was brighter in shorter exposures than in longer exposures. The Cameron 2006 catalog ID=326 and weight="confirmed". The ALPO/BAA weight=2.
Harpalus 1969 May 19 UT 21:20-22:00 Observed by Marcomede Rangel Nunes and Julio Dias Nogueira (Rio de Janeiro, Brazil, 18" refractor). "Brightening in crater (inexperienced observers). (Apollo 10 watch)." NASA catalog weight=0. ALPO/BAA weight=1. NASA catalog ID #1126.
In 1865 Jan 01 at UT 18:00-18:30? Grover (England? or USA?, seeing = good and transparency = clear) observed south east of Plato at the foot of Mt Blanc a small bright spot like a magnitude 4 star - slightly out of focus. This bright speck remained unchanged for 30 minutes. The Cameron 1978 catalog ID=137 and the weight=3. The ALPO/BAA weight=2.
On 1969 May 20 at UT 19:35-20:30 Gomez (Spain, 12" reflector) observed blue-white pulsating light in Aristarchus that illuminated the inner walls - it was maximum at 19:55UT. This observation was made during the Apollo 10 watch. The Cameron 1978 catalog ID=1128 and weight=5. The ALPO/BAA weight=2.
On 1988 Apr 21 at UT 01:28-04:00 D. Fryback (Madison, WI, USA) took a series of photographs - Aristarchus was a luminous patch and in one photograph a red spot (Cameron suspects marks on the film). is seen near Aristarchus. Strangely though when looking through the telescope, the crater was not excessively bright. D. Spain (Fairdale, KY, USA, 3.5" reflector?, x60) observed a narrow white streak of mag 5-6 of duration 0.5 sec that covered 160-320km near the centre of the Moon at 01:53UT. A similar streak happened but the direction was different. Next 2 small red flashes were seen at 02:00 and 02:01UT of magnitude 7 (<1sec) in the vicinity of Aristarchus. The cameron 2006 catalog ID=327 and the weight=1.
On 1847 Dec 11 at 18:00UT Hdgson (Eversley, UK, x80 refractor and 40x reflector) observed in Plato (Though it might have been Cape Agassiz or Teneriffe Mts) a bright spot of about a 1/4 the angular diameter of Saturn that varied intermittently and was at all times visible on the night side of the Moon. The following day he glimpsed the same spot rhough clouds. From his drawing the spot was ~5' below the true N. point & near the following limb (IAU E. limb) Cameron comments that Plato fits the angular distance better than the other two candidates unless there was a large northern libration. The Cameron 1978 catalog ID=125 and weight=3. The ALPO/BAA weight=3.
On 1969 May 20 at UT 21:00-22:00 Bury (France, 4" refractor) observed Aristarchus to be very bright, as an elliptical bluish spot at 21:00UT. This observation was made during the Apollo 10 watch. The Cameron 1978 catalog ID=1128 and weight=5. The ALPO/BAA weight=2.
On 1988 Apr 21 at UT 01:53 D. Spain (Fairdale, KY, USA, 3.5" reflector?, x60) observed a narrow white streak of mag 5-6 of duration 0.5 sec that covered 160-320km near the centre of the Moon at 01:53UT. A similar streak happened again but the direction was different. Next 2 small red flashes were seen at 02:00 and 02:01UT of magnitude 7 (<1sec) in the vicinity of Aristarchus. The Cameron 2006 catalog ID=327 and the weight=1.
On 1969 May 20 at UT 21:10-22:30 Marcomede Rangel Nunes and Julio Dias Nogueira (Rio de Janeiro, Brazil, 18" refractor) Harpalus brighter than Bouguer - this was during the Apollo 10 watch and Cameron comments that the observers were inexperienced.

On 2011 Apr 07 UT 19:45-20:10 Aristarchus was seen to be “very bright” in Earthshine. Giorgio Sancristoforo (Milan, Italy, 203mm SCT, atmospheric seeing good) noticed Aristarchus to be exceptionally bright (Sketch supplied) at around 20:00 and was the first to report this. Although he did not record the start and end times, he commented that the effect lasted 20-30 minutes and then was significantly reduced in brightness. Although direct comparison in terms of brightnes could not be made with a star, he thought Aristarchus to be brighter than +0.7 in magnitude (Saturn). Furthermore Aristarchus was visible when daylight was still present, when looking through the telescope, although it could not be seen with the naked eye due to too much extraneous light. Aristarchus was probably white in colour, but the observer was partly colour blind and so was uncertain. Not much detail was seen elsewhere in Earthshine, even when the sky darkened, and he was not able to see Kepler or Copernicus, just the limb. No details were seen in Aristarchus itself, for example no ray to the SW was visible. It later transpired that Lajos Bartha (Budapest, Hungary, 70mm refractor, x83, seeing conditions good) had observed Earthshine even earlier from UT19:45-20:10 and noticed a bright area close to the edge of the Moon that he later confirmed was Aristarchus. When he started observing the sky twilight was still a deep blue, but the dark side of the Moon was seen both with the naked eye and through the telescope. Earthshine was medium in brightness and grey in colour. Copernicus and Kepler were weak in brightness but certainly visible. There was some scattered light from the sunlit side of the Moon noticed, but not enough to obscure Copernicus and Kepler from visibility. As a test he moved the telescope around and the bright spot moved with the Moon and so was not a glare problem. The following day he checked Earthshine again but found that the bright spot was not so conspicuous. As a footnote, Tim Haynes (UK) had been observing an occultation of 37 Tauri, much earlier at 19:14UT, through 10x50 binoculars. He commented that Earthshine was visible, but that he hadn't noticed Aristarchus - though he was not looking at the Moon specifically to see this crater. ALPO/BAA weight=3.
On 1912 May 20 at UT 21:00 Franks (6" refractor) observed the Leibnitz Mountains? (South Pole area) to have a small red glowing area on the dark part of the Moon. The Cameron 1978 catalog ID=338 and weight=1. The ALPO/BAA weight=2.
On 1969 May 21 at UT 20:00-21:00 Brandli and Germann (Switzerland, 6" refractor) observed a slow orange-red blinking on the surrounding area of Aristarchus. It was seen less markedly the next night. Wald (Zurich, Switzerland) noted at 20:30UT that the crater was pink (Confirmation says Cameron) - this was during the Apollo 10 watch. The cameron 1978 catalog ID=1131-1132 and weight=5. The ALPO/BAA weight=4.
South Cusp 1969 Jul 19 UT 17:55-19:10 Observed by Dzapiashvili (Georgia, Soviet Union) "Saw an abnormally bright spot at end of S.cusp. Polariz. meas. at 8.3% at 1845-1847h (Apollo 11 watch?)" NASA catalog weight=5 (very good). NASA catalog ID #1164.
On 1975 Mar 18 at UT 00:57-04:00 Reiland, Brown and Lojeck (Pittsburgh, Pennsylvania, 6" reflector x45 and 8" reflector x200, photos taken) observed the following at Aristarchus: "While obs. Earthshine on moon, saw it glowing -- a bright steady star-like glow, est. at 5-8th mag. First noted at 0057h. Obs. other obj. then came back to it. It was still there -- till moonset (@0500h). Saw it in other telscopes & Lojeck took photos. (photo shows Aris. prominent, but also LaLande, Pytheas & Timocharis. 2 prs. in Aris. but there are other pts on the print, it may be grain)".

Fracastorius 1973 Mar 09 UT ~19:57 Robinson (Devon, UK) saw a Moon Blink (colour) in this crater. This crater is long suspected of giving permanent blinks due to natural colour. The ALPO/BAA weight=1.
On 1969 Jul 19 at UT 1845-18:47 Pruss and Witte (Bochum, Germany, 6" refractor x36 and binoculars) saw brightenings in the north west wall of Aristarchus for 3-7 seconds of about 1 magnitude over the background. From orbit at UT 18:46 the Apollo 11 crew Armstrong, Aldrin, and Collins (in orbit around the Moon and using the naked eye) were asked to take a look at Aristarchus after Earth-based reports of TLP activity. Armstrong reported (after the solar corona had set, on the night side) that probably Aristarchus "to be considerably more illuminated than the surrounding area. It just has - seem to have, a slight amount of flourescence to it". Collins reported a moment later: "Looking out on the same area now. Well at least there is one wall of the crater that seems to be more illuminated than the others. I am not sure that I am actually identifying any phosporesecence, but that definitely is lighter than anything else in the neighborhood". Houston then asked if the crew could detect any colour and if the inner wall was the inner or outer part? Aldrim commnted that it was the inner wall and Collins mentioned thatno colour was incolved. The Cameron 1978 catalog ID=1165 and weight=5. The ALPO/BAA weight=3.
On 1969 Jul 19 at UT 19:30-21:30 Gervais (Lodure, France, 4.5" refractor?) saw the whole region of Aristarchus and its environs as brighter than normal. Two photographs were obtained. The Cameron 1978 catalog ID=1156 and weight=5. At UT 20:30-20:55 Oliver (Spain, using a reflector) found the Aristarchus to have brightened by about 1 magnitude. From UT 20:12-20:30 the crater had been normal. The Cameron 1978 catalog ID=1167 and the weight=2. At UT 21:00-00:35 P. Mourilhe Silva (Rio de Janeiro, Brazil, 19.5" refractor) saw Aristarchus as a very bright elliptical shape which extended to the north like a bridge between two points. Jose M. L. da Silva and Ronaldo Mourao (Rio de Janeiro, Brazil, 13" refractor) saw a brightening on the north west wall from 21:24-23:22UT intermittently but cont'd. Wall was extraordinarilly bright, along NW wall brighter. Moseley (Armagh, Northern Ireland, UK, 10" refractor) detected an unusual bright, along north west wall, brighter than normal in Earthshine and brighter than crater. It was not constant, but pulsated irregularly with frequency of 20 seconds and amplitude 0.75-1.0 magnitudes. No colour seen or obscuration though lokked for. Clouds interrupted observations. Vasquez (Valparaiso, Chile, 12" reflector) saw it as a very luminous point of magnitude 1. Wairy Cardoso (Rio de Janeiro, Brazil, 12" reflector and 18" refractor) noted a bright. 1s??? The Cameron catalog ID=1168 and the weight=5. The ALPO/BAA weight=4.
Theophilus 1969 Jul 19 UT 19:30-21:30 Observed by Fox (Notts. England, 6.5" reflector) and Ringsdore (England, 15" reflector). Fox saw intermittent glow in Theoph. for > 2h (time not given).

On 1966 Sep 20 at UT 03:22 Three Astronet observers (Phoenix, AZ, and Los Angeles, CA, USA) (independently?) reported flashes in Grimaldi crater. One observer was in Phoenix AZ, and another in Losa Angeles, CA, so probably not due to the atmosphere. Cameron comments that the astronaut Schmidt on Apollo 17 saw a flash in it while orbiting the Moon. the Cameron 1978 catalog ID=977 and the weight=5. The ALPO/BAA weight=4.
South Pole 2011 Apr 08 UT 19:30-20:00 A.Kemp (Mold, Flintshire, UK) observed that the Leibnitz peaks at the southern pole stood out sharply. However one of the peaks was “shining like a spot light. So bright that I couldn’t make out its shape”. – image clear and steady with excellent transparency and seeing in the 70mm f/13 refractor (25mm and 10mm eyepieces). Inspections during the above time period revealed no changes in brightness. Previous observations of this area had never shown such an unusual brightness, and Arthur likened the brightness to “a maximum brightness of Venus shining amongst 2nd magnitude stars”. The observer was an experienced observer. ALPO/BAA weight=2.

Grimaldi 1969 Jul 19 UT 20:39-20:45 Delaye (France, 25cm refractor) saw a bright bluish spot near Grimaldi. 20:43 a flash was seen by Thinon. Delaye saw flashes at 20:44 and 20:45. Between 21:00 and 23:00 (J. M. L.) da Silva (Rio de Janeiro, Brazil, 19.5" refractor) saw a bright spot on the W (IAU??) of Grimaldi. However there is a bright spot near Grimaldi, so this maybe normal. NASA ID = 1167. The ALPO/BAA weight=2.
On 1990 Mar 31 at UT 21:30 L. Jackson (England, UK?) observed a red glow in Earthshine in Gassendi as shown in a sketch.

On 1984 Jul 04 at UT 22:05-23:09 Richardson (Swinton, Yorkshire, UK, seeing=VE) found that a peak west of Theophilus crater had a deep blue colour, and this was strange because no colour was seen elsewhere on the Moon. Foley (Kent, UK, 12" reflector), once alerted, found a dome east of Kant? to be blue, and likewise no colour was seen elsewhere on the Moon. Cameron 2006 catalog ID=246 and the weight=4. The ALPO/BAA weight=3.
On 1984 Jul 04 UT 22:08-23:09 Foley (12" reflector, Kent, UK) found that Torricelli B was a much lower brightness than was expected and this remained the case for the rest of the lunation. The Cameron 2006 catalog ID=246 and the weight=4. The ALPO/BAA weight=1.

At 20:05UT it's spot brightened, at 20:08:50-20:35:50UT brightening and pulsations of variable duration. At 20:55:50UT just a feeble flash. Cameron comments that this is probably not atmpsheric effects as the period is too long - also it was during the Apollo 11 watch. The Cameron 1978 catalog ID=1175 and th weight=3. The ALPO/BAA weight=3.
Mare Crisium 1826 Apr 13 UT 20:00 Observed by Emmett (England?) "Black moving haze or cloud" NASA catalog weight=2 (low). NASA catalog ID = 109. ALPO/BAA weight=1.
On 1969 May 22 at UT23:20 an unknown observer reported some brightenings with pulsations in Aristarchus crater, Cameron suspects atmospheric aberrations. This was during the Apollo 10 watch. The Cameron 1978 catalog ID=1136 and weight=1. The ALPO/BAA weight=1.
Knopp of Paysandu, Uruguay on 1885 Feb 21 at 23:00-23:30? UT saw red patches in the crater. Reddish smoke or mist. The observer says several others had seen a star like point there that night. Cameron's 1978 catalog ID=348 and weight=4. ALPO/BAA weight=3.
Triesnecker Rille 1912 May 23 UT 18:00? Observed by Gordeenko (Russia) "Change in shape from representation by Brenner and Krieger not accountable by lighting conditions" NASA catalog weight=0. ALPO/BAA weight=1. NASA catalog ID #339.
On 1987 Jun 04 at UT02:26-03:26 D. Darling (Sun Praire, WI, USA, S=G and T=4) observed that Mons Piton was the brightest object on the Moon that he had ever noted before. Variations seen gave the mountain a "silvery" shine. The abnormal brightness was confirmed by another independent observer. The Cameron 2006 catalog ID=302 and the weight=5. the ALPO/BAA weight=2.
Mt Piton 2001 Sep 24 UTC 19:25-19:55 Observed by Marie & Jeremy Cook (Frimley, Surrey, UK) described Mt as the brightest point on the terminator flaring seen on the southern end and red in colour. Observers really thought it was normal (not a TLP) to be this bright and the flaring was spurious colour. Worth checking out just in case, and also because it looks spectacular. ALPO/BAA weight=1.
Theophilus 1969 Jul 21 UT 19:30-21:45 and 21:00-22:00 Observed by Fox (Newark, England, 6.5" reflector,) and Baum (Chester, England, 4.5" refractor) (S=6, T=4) "At wall, adjacent to Cyrillus was a redish glow, then obscur. (Fox). Baum saw intermittant white-blue shimmering as if glowing thru dust glowing & upsurge in brightness on c.p. Gradually faded to normal at 21:20. 1st time ever seen by him tho. obs. since 1947. Image sharp, no haziness. (indep. confirm. of activity, but details differ, but same time, Apollo 11 watch)." NASA catalog weight=5. NASA catalog ID #1180. ALPO/BAA weight=3.
On 1991 May 21 at UT05:30-06:15 J. Green (Orangevale, CA, USA, 11" reflector) photgrapphed a broad bright band stretching east and north of Cassini crater in 3 exposures taken 10 minutes apart. This photographic sequence shows a gradual widening towards Cassini and by the 3rd exposure the band is touching (and then obscuring) Cassini. A "fan" was visible in the north east and WSW directions, later this was seen as rays and this was even seen in the view finder of the camera. Cameron comments that this might be lens flare but suspects that it would not have been seen in the view finder. The Cameron 2006 catalog ID=427 and the weight=5. The ALPO/BAA weight=2.
Hyginius Cleft 1966 Jul 25 UT 04:40 observed by Kelsey (Riverside, CA, USA, 8" reflector, x300) "Points at opposite ends of cleft were very brilliant in red Wratten 25 filter & very dull in blue Wratten 47 filter. Richer uncertain if real LTP." NASA catalog weight=1. NASA catalog ID #957.

Knopp of Paysandu, Uruguay on 1885 Feb 22 at 23:00-23:30? UT saw a definite light, looking like Saturn in Cassini?. The previous night he had seen red patches in the crater. Cameron's 1978 catalog ID=348 and weight=4. ALPO/BAA weight=3.
Plato 1895 May 02 UT 20:45, 23:45 Observed by Brenner and Fauth (Germany?) "Streaks of light (Brenner) bright parallel bands in center Fauth (indep. confirmation?)." NASA catalog weight=5. NASA catalog ID #284. ALPO/BAA weight=1.
Plato 1972 Jun 19 UT 21:40-22:30 Observed by S.A. Jones (Swansea, Wales, 12" reflector x150) and Moore (Selsey, England, 12.5" reflector x450) "Noted a bright area in the center. Moore noted nothing unusual & he tho't obs. saw one of permanent light patches" NASA catalog weight=0 (very low). NASA catalog ID # 1336. ALPO/BAA weight=1
On 1979 Dec 27 at UT 05:32 D. Louderback (South Bend, WA, USA, 6" reflector x240, seeing=3-6/10 and T=4) noticed "2 small high-sun areas nr. Eimmart - brightening around Mare Crisium, except for interior of Proclus - in blue light. They were brighter than 2 spots on Cap. Agarum rated 8.5 & Proc. 9. Not as bright next night. Probably a real blue light brightening". Cameron 2006 catalog ID=79, location on Moon: (70E, 23N) and weight=4.
On 1965 Sep 03 UT03:00-05:00 D.Harris (Located near Whittier College, Whittier, CA, USA, using a 10" f/8.2 Newtonian reflector, x78 & x208, seeing 5-6, transparency 2-0) observed a ridge obscured SSW of Ross D. No drawing was made, only a written description. "Ridge not visible near crater; possible white patch 1/3 Ross D diameter" The ridge is the wrinkle ridge extending NNE from Ross D, a well established often visible feature. Harris comments that this was not one of the better TLPs seen near Ross D, and there were no independent observers, neverless he was ceratin of this being a TLP, and it was consistant with other activity seen near this crater between 1964 and 1970. Cameron 1978 catalog ID 891 and weight=3. ALPO/BAA weight=2.
Plato 1887 Nov 23 UT 20:00? Observed by de Speissens (France?) "Luminous triangle on floor. Klein says it was sunlight affect. (but similar to Klein's own obs., #190. Fort says never seen before nor since)." NASA catalog weight=0 (very unlikely). NASA catalog ID #256. ALPO/BAA weight=1.
Censorinus 1969 May 24 UTC 21:10-22:15 Observed by Jean Nicolini (Sao Paulo, Brazil, 12" reflector) "It was brighter than Proclus between 2130-2145h. A very tiny cirrus veil present & Censor. appeared less bright & Proc. continued to look normal. Weather worsened at 2215h. (Apollo 10 watch)." NASA catalog weight=2. NASA catalog ID #1144. ALPO/BAA weight=1.
Theophilus 1978 Nov 08 UT 20:49-22:00 Observed by J.D. Cook (Frimley, 12" reflector, 6mm Ortho eyepiece, seeing III-IV) Orange discolouration seen on ESE crater floor. Moon blink tried, but no blink detected. By 21:10 the effect had lessened, but was still orange. By 21:50-21:58 the effect was smaller and perhaps more on the SE of the floor. Colour confirmed by Foley. Fitton may also have been observing. At 22:00 A.C. Cook observed and commented that a darkish, perhaps brown-orange colour seen - but suspected it was probably spurious colour - but by now the seeing was V. J.H. Robinson, whilst doing a Moon Blink sweep of several features, including Theophilus, had not noticed anything unusual 18:50-19:10. By 22:30-22:35UT, he still could not detect a blink, but noticed intermittent darkining on the shaded area on the E. floor, but seeing was now IV. The darkening was more noticeable in blue than red light. BAA Lunar Section observation. 2006 Cameron catalog ID #40 weight=3. ALPO/BAA weight=1.
Piton 1960 Nov 27 ? UT 00:00? Observed by Schneller (Cleveland, OH, USA, 8" Reflector, x53), "Red obscuration concealing peak, @10m2 (if near SR, date is 27th; ancillary data given for 27th -- date not given)." NASA catalog weight=3 (average). NASA catalog ID #731.
On 1972 Feb 23 at UT0010-0035 Fornarucci (Garfield, NJ, USA, 6" reflector, x250, seeing=fair and transparency=3.5). Shading usually visible west of it was not seen. Cameon comments that the albedo must have been at 5, where normally it is 4.5 and the nearby plain is 5). Cameron 1978 catalog ID=1322 and weight=2. ALPO/BAA weight=2.
Alpetragius 1889 Aug 03 UT 03:00-03:45 observed by E.E. Barnard (Lick Observatory, CA, USA, 36" refractor, x150, x700) "Shadow of CP diffused & pale. Entire inside of crater seemed filled with haze or smoke. Shad. of E. wall was black & sharp. CP & floor seen thru haze. No other craters showed this appear.

Photo of bright red spot nr. Mask. (confirm. -- Apollo 10 watch)" NASA catalog weight=5 and 5 (very high). NASA catalog ID #1145.
On 2009 May 03/10 UT23:20-00:11 P. Abel (Leicester, UK, 20cm reflector, x312, seeing III-IV) observed that the north east wall was slightly brighter than would have been expected, slightly blurred (not seeing related blurring) and had a strong orange-brown colour. No spurious colour seen elsewhere. A change in eyepieces showed the same effect. No luck in alerting other observers. A drawing was made at 23:20UT and finished at 00:12UT. At 23:12UT part of the inner NW floor had a dull brown colour, whereas before it was grey.By 00:11UT the colour effect was fading and by 00:18 seeing condirions were too bad to continue. M. Cook (Mundesley, UK, 9cm Questar telescope, x80, x130, seeing III, transparency moderate to good) had observed Tycho earlier in the evening at 22:15UT, but had seen no signs of colour. W. Leatherbarrow (Sheffield, UK, 8cm scope, high cloud interuptions and bad seeing) had taken monochrome images at UT 20:07 and 20:10, but these showed nothing unusual, and he checked the crater visually at 00:00-00:30, but detected no colour, although the Moon's low altitude contibuted to poor seeing conditions and some spurious colour was seen. CCD images from M. Collins (Palmerston North, New Zealand) taken at 00:46UT showed nocolour apart from spurious colour on contrasty edges, in no way reflecting what was seen early by P. Abel. The ALPO/BAA weight=2.
Observer made a drawing over a period of 30 minutes. Upon examining drawing, and comparing with photos made under similar illumination was struck by the abnormality of a a small white blob in the north east corner of the shadowed floor. There should be no raised topography between the wall and the central peaks that could give rise to this. The making of the sketch overlapped with an earlier drawing made by Rony de Laet (Belgium) which did not show this blob. Subsequent attempts to find sketches/images at very similar illumination angles have failed to show the blob in the north east corner of the chadowed floor. ALPO/BAA weight=3.
Birt 1955 Apr 15 UT 03:20-05:00 Observed by Capen (California Seeing=Excellent) "Small craters between Birt & wall were invis. at times under excellent seeing, while craterlets on w.side were continually obs." NASA catalog weight=4 (high). NASA catalog ID #586.
On 1990 Apr 04 at UT 21:30-21:50 B. LeFranc (France?) reported observing a white flame effect in Copernicus crater (sketch made) - though Foley comments that the actual location was east of the crater. The Cameron 2006 catalog ID=398 and the weight=2. The ALPO/BAA weight=2.
Plato 1964 Nov 14 UT 01:00? Observed by Bartlett (Baltimore, MD, USA, 4" refractor?) "Peak on E. wall brilliant white, strong blue band at inner base; on S. wall was a small, bright red spot." NASA catalog weight=4 (good). NASA catalog ID #864.

On 1968 May 07 at UT 03:00-03:40 Kelsey (Riverside, CA, USA, 8" reflector) observed Messier and Messier A and noted the following: "The ray-tail halo (in N. ray) showed a possible enhancement in blue filter at 1st obs. per. but not seen at 0330. Later enhancement was indicated in red filter but not apparent at 0600h. The red enhancement is very unsual; but has been suspected on a few previous occasions. Not seen vis. (confirm. of Jean?)" The Cameron 1978 catalog ID= and weight=5. The ALPO/BAA weight=3.
Tycho 1970- Apr 15 UTC 22:00-23:00 Observer: Nelson Travnik (Matias Barbosa, Minas Gerais, Brazil, 4" refractor, x250 & x400, seeing excellent, Wratten 15 and 23 filters used) "Slightly pulsating white glow on W.

On 1982 Oct 26 at UT 20:41-22:22 P. Madej (Huddersfield, UK, seeing=II and transparency=good) found that a blurring effect on the crater Yerkes had spread to Picard (~3.5 deg brightness). The effect was not detected in yellow light from the Wratten 15 filter, but a brightness change was picked up in red Wratten 25 light. J.D. Cook found dark surrounding Picard bright illumination. The Cameron 2006 catalog ID=188 and weight=5. The ALPO/BAA weight=3.
Yerkes-Picard 1982 Oct 26 UT 20:41-22:22 and 21:31 Observed by Madej (Yorkshire, England, Seeing II, Transparency Good) and Cook (Frimley, England, Seeing=II, Transparency Good) "(Madej) could not focus Yerkes as well as could Peirce. By 2041 effect extended to Picard (~3.5 deg). In W15 filter not apparent, but albedo change was very marked in W25 red filter. (M. Cook) at 2222 noted faint orange around Yerkes E. Spurious color seen in other areas. Color around Yerkes intermittent. In blue filter it was still orange. (J. Cook) at 2131 noted S rim of moon was orange & seeing was such that it was fizzing. Around Yerkes only orange tint - tending intermittent" Cameron (2006) catalog ID #188 & weight=5 (very good). ALPO/BAA weight=1.
Manilius 1970 May 04 UTC 19:20 Observer: Mansfield (Cape Town, S.Africa), distinct pink colour noticed. NASA catalog ID No. #1294. Weight assigned to this observation by the NASA catalog was 3 (average).
Proclus 1972 Mar 24 UTC 16:29-19:22 observed by Hopp (52.5N, 13.25E, 75mm refractor) "Enormous brightening, vanished until 1922. Pattern changed from oval to circular several times."Hilbrecht and Kuveler, Earth, Moon & Planets, 30 (1984), p53-61
On 1990 Apr 05 at UT 00:43-01:46 D. Darling (Sun Praire, WI, USA, 3" refractor, x90) observed that Bullialdus (the crater was in shadow) was pink in colour on the edge of its wall. The effect lasted from 01:15- 01:44UT and he could discern the terrace on the western wall. Comparisons were made to Tycho and Copernicus - all of which were normal. The Cameron 2006 catalog ID=399 and the weight=3. The ALPO/BAA weight=3.
Plato 1966 Jun 27 UT 21:40-21:55 Observed by Robinson (Teignmouth, England, 10.5" reflector) and Sartory (England, 8.5" reflector + Moon blink) "Color (red?) on SE wall detected by Eng. moon blink sys. (confirm)." NASA catalog weight=5 (very high). NASA catalog ID 949.
Plato 1969 May 26 UT 20:30-21:05 Observed by Farrant (Cambridge, England, 8" reflector, x160, S=G) "Had misty portion of SW(ast. ?) floor from 2030-2105h at which time it was gone. Clearly seen, had ill-defined boundaries & was an easy obj. to see. Alt. =33 deg. (Apollo 10 watch)." NASA catalog weight=3. NASA catalog ID No. 1148. ALPO/BAA weight=2.
Proclus 1989 Jul 13 UT 21:04-21:13 Observed by M.Cook (Frimley, UK, 90mm Quastar Cat., Seeing III, transoparency hazy) and by Moore (Selsey, England) "Following an alert call by Miles concerning the crater Proclus looking different, Cook observed a circular dark patch that filled about half of the eastern half of the crater floor. To cut down the glare a blue filter was then used and a slightly less dark area was seen extending from this in a southerly direction. 8 rays were seen. The dark patch was confirmed by Patrick Moore. However David Darling (USA) who observed a few hours later on 1989 Jul 14 at 03:28 UT could not see this dark patch." BAA Lunar Section observation. The Cameron 2006 catalog ID=370 and weight=?. The ALPO/BAA weight=2
Scarcely a trace of nebulae tonight. As long as to June 10 at 2000UT? A little blackness remained. (P. Moore thinks it was a LTP, WSC it was a permanent feature?) Drawing. Seen by Nevelius Emmett, J. Boroughbridge, England. The 2006 Extension catalog by Cameron assigns an ID No. of 4 and a weight of 1. The ALPO/BAA weight=1.
On 1983 Jul 20 at UT 18:50-22:40 P.W. Foley (Kent, UK, 12"reflector, seeing II-III) noted that the south wall of Plato at the 11 o'clock position, at the location of a cleft, was fuzzy on either side of the cleft. There was also a deep red colour along the cleft and the outside wall. The colour had gone by 22:40 though. All other parts of the rim of Plato were clear and distinct. M. Cook (Frimley, UK, seeing III) sketched some obscurations at 22:03UT. At 22:08UT the red colour reduced to a red line and vanished by 22:37. The south wall obscuration varied in size and there was a possible obscuration at the 7 o'clock position. J. Cook (Frimley, UK, seeing II-III) confirmed Foley's and M.Cook's observations. Detail inside the crater was sharp, but colour oppoiste to what is usual. Price (Camberley, UK, seeing IV-V) a few km away had atmospheric ripples affecting his observations. At 21:36UT G. North described the south wall as odd in appearance and the terrain south of this was lacking in detail - this was odd because elsewhere Plato was nice and sharp. At 21:45UT though the north section of the crater was a hazy red. The cameron 206 catalog ID=224 and the weight=5. The ALPO/BAA weight=3.
Campanus 2014 Jan 11 UT 22:00-22:30 S.Bush (UK, 6" SCT, x180, seeing average) made a sketch of the Campanus and Mercator craters. He found that the central peak of Campanus difficult to resolve and the floors of both craters were devoid of detail. Mercator was the lighter shade of the two floors. Earlier at 19:47 UT M.Brown (Huntingdon, UK) imaged this region and using Registax resolved details on the floors of both craters, though Mercator clearly was slightly lighter in floor shade and had less detail on its floor than Campanus. The most likely explanation was that it was just seeing effects blocking the visibility of detail - this of course is less of a problem for a Registax usid on the CCD image. However just to be sure this observation is being given an ALPO/BAA TLP weight of 1, to encourage visual observers to attempt this observation under similar illumination and seeing.
On 1983 Aug 19 at UT 07:15-07:30 D. Louderback (South Bend, WA, USA, 3" refractor, x150) found that the direct sunlit side of Mons Piton mountain (E) was brighter than (his designated) points C and D and this happened at the same time as some "blurring"at 07:15UT. The darker side, between C, A and B were not so dark through a red filter as through a blue filter (this was the opposite of what had been seen before at a high sun angle). Louderback suspects that there had been a colour change since he last observed. He also noted that in red light the whole lunar disk appeared fuzzy and out of focus. Louderback noted a 1 sec brightness on the east slope and the whole mountain sharp in blue light. The Moon's altitude was low though. Brightness measurements were 4 in blue light and >= 4.6 in red light and "so illdefined almost blended into plain". Cameon commnets that a telescope colour/focussing issue may have been at work here! The Cameron 2006 catalog ID=226 and weight=4. The ALPO/BAA weight=1.

Gassendi 1967 Jun 18 UT 22:50-23:59 Observed by Whippey (Northalt, England, 6" reflector?) "Faint redness outside NE & SE wall of crater." Moore (10" Armagh refractor, x360) was observing earlier 22:10-22:40, with and without a Moon Blink but detected no redness, however his observing conditions were not very good at the time. NASA catalog ID #1039. NASA catalog weight=3. ALPO.BAA weight=2.
Aristrachus 1966 Jul 29 UT 03:40 Observed by Simmons (Jacksonville, FL, USA, 6" reflector x192, S=7, T=4-5) and Corralitos Observatory (Organ Pass, NM, USA, 24" reflector + Moonblink) "Spot on S.wall vis. only in red filter, brightness 8deg. Slightly brighter than surrounding wall. No confirm. Says it might be part that reflected better. Not confirmed by Corralitos Obs. MB." NASA catalog ID #968. NASA catalog weight=1 (very low).
Aristarchus 1975 Dec 14/15 UT 17:05-00:30 Observed by Foley (Dartford, England, 12" reflector, S=II) and Moore (Sussex, UK, 15" reflector x250 S=IV) and Argent and Brumder (Sussex, UK). In early sunrise conditions, W. wall was less brilliant than usual -- matched only by Sharp, Bianchini, & Marian. Extraordinary detail could be seen on this wall. Also noted intense & distinctly blue color entire length of W. wall. 3 others corroborated detail, but not color. Moore found things normal & saw Aris. brightest at 2030-2125h tho Argent & Brumder made it < Proclus" NASA catalog weight=4. NASA catlog ID #1422. ALPO/BAA weight=1.
On 1938 Mar 13 at UT 04:00-06:00 Barker (Chestnut, England, UK) noted a slight reddish colour in Plato. However Fox (Newark, UK, 6.5" reflector, x240) saw none on the south east wall, but instead saw a yellowish glow on the southern floor at the same time (confirmation?). Appearently Fox saw the same effect on Apr 10, 11, and May 8-11, then on June 8-10. The Cameron 2006 catalog ID=432 and the weight=5. The ALPO/BAA weight=3.
On 1982 Sep 29 at UT 05:52UT D. Louderback (South Bend, WA, USA, 8" reflector, x240) saw approximately 7-8 diameters from Aristarchus (72W, 15N) a star-like point on the dark side - uncertain if this weas on the limb or inside the disk of the Moon. Cameron 2006 catalog ID=185 and weight=1. ALPO/BAA weight=1.
On 1989 May 17 at UT Fabian (Chicago, IL, USA, 4" reflector, x35-x50 and 8" reflector) noted a pale blue colouration in the ridges situated west of Aristarchus and north of Herodotus craters, in the vicinity of the terminator (and on the night side). Aristarchus itself did not have any colour. Ďt was only area with such color though there were numerous others of similar elevation and relation to term. The colour was seen in a 4" Cassegrain telescope, but when an 8" reflector was used at 02:30UT, even with the same eyepieces. Cameron comments that maybe the larger telescope spread the colour out? The sketch that Fabian suplied, suggested to Cameron that the TLP was located at Herodotus, and the ridge was part of Schroter's valley - Cobra Head. The Cameron 2006 catalog ID=364 and the weight=2. The ALPO/BAA weight=2.
On 1978 Jan 20 at UT19:10 P.W. Foley (Kent, UK, 12" reflector) observed a red spot at the southern edge of Gassendi C. P. Moore (Slesey, UK, 15" reflector, S=II-III) reported nothing unusual 17:00-17:50. Turner and others reported negative at 22:01. Pedler (UK, 12.5" reflector, S=III-IV) though detected a yellow-orange tint on the east floor of Gassendi A but the effect faded during poor seeing moments. Cameron 2005 catalog ID=24 and weight=5. ALPO/BAA weight=3.
On 1975 Feb 22 at 19:00-22:50 Fitton (Lancashire, UK, 8" reflector, seeing=II-III-I) saw Aristarchus (at 19:00UT) blue, with no obscuration visible in white, red or blue filters. This was not a telescopic effect. "Obs. 4.5h. Says it & next 5 nites obs. were due to high pressure system W. of obs.". Foley found nothing unsual in Aristarchus in his observing session, which overlapped Fittons. The 1978 catalog ID=1396 and weight=3. The ALPO/BAA weight=1.
On 1975 Feb 22 at 20:04-22:50 P.W. Foley (Kent, UK, 12" reflector, seeing=good) observed Prinz to have a diffuse white obsecuration. There were pulsations of 30-50sec intervals. Effect ceased at 22:50UT and indeed was fading earlier from 22:35UT. Photgraphs were taken but showed nothing unusual and no colour. Aristarchus was also negative. The Cameron 1978 catalog ID=1396 and weight=3. The ALPO/BAA weight=2.
On 1969 May 28 at UT 02:18 Delano (Taunton? MA, USA, 12.5" reflector, x300, seeing=fair and transparency=good) through the red filter at 02:18UT saw a bright area on the west wall of Aristarchus crater become 2x brighter than normal then faded back to normal in < 1 min duration. The spot was 8km centred on sigma=0.682 and eta=0.397. No events seen at Kepler (Apollo 10 watch). The Cameron 1978 catalog ID=1149 and weight=4. ALPO/BAA weight=3.
Aristarchus 1989 Jul 15 UT 02:00-04:20 Observed by Manske, Weier, Curtis, Keyes, Yanna, Norman, Knutson, Sullivan, Eichman and Radi (Carl Fosmark Jr. Memorial Observatory, Madison, WI, USA, SCT C11) "Manske initially observed a reddish tinge on the SE rim of Aristarchus. The colour was present in different eyepieces. Two other pinkish tinge areas were seen on the SE and NE rims. 4 of the observers did not see colour. Independent confirmation was made by Don Spain (KY) and Smith in LA. Full details can be found on the following web site: http://www.ltpresearch.org/ltpreports/LTP19890715.htm " An ALPO report.
On 1969 May 28 at UT 02:18 Delano (Taunton? MA, USA, 12.5" reflector, x300) suspected a short duration flare up on the W wall of Aristarchus at 0.682 and 0.397, but it may have been due to poor seeing. No events seen at Kepler (Apollo 10 watch). The Cameron 1978 catalog ID=1149 and weight=4. ALPO/BAA weight=1.
On 1980 Dec 18 at UT20:46-23:58 A.C. Cook (Frimley, UK, 12" reflector, 40-250x, S=IV and transparency good) found the north west wall to be brighter in red than in blue light, however the effect faded during 21:29-21:41UT and was gone by 22:40UT. There was however spurious colour on the north west wall. M. Cook (Frimley, UK) found the central peak to be both bright and diffuse, and brighter in red than in blue light during 20:52-20:57UT, however at "22:53-23:58 c.p. very bright & previous area decreased in size. No detail in white or red, just visible in blue. Sketch (J. Cook) Orange out on NW rim & on NW side of c.p. Similar effects seen on other craters. (madej) c.p. & W. rim wall very sharp. c.p. disappears in yellow but still seen in purple. (pedler) c.p. > red than blue but no obstruction. W wall interior dusky, darker in blue." A.C. Cook's photo depicts the central peak as very bright. Cameron 2006 catalog TLP ID=120 and weight=5. ALPO/BAA weight=2.
On 1992 May 13 at UT 20:16-21:29 several observers reported a TLP in Plato mostly concerning the visibility of floor craterlets, however observer seeing varied from III-V. North (UK, 18.25" reflector) reported "Colouration and floor craterlets very prominent. Seeing Antoniadi V, Transparancy Poor.". Foley (Kent, UK, 12" reflector seeing=III-IV) found the floor to be bright and in the better moment of seeing detected floor craterlets. The WNW spot was misty some of the time. Moore (Selsey, UK, 15" reflector, seeing V) had very poor seing conditions. J.D. Cook and M.C. Cook (Frimley, UK, 3.6" reflector, seeing II-III) used a CCD camera at 22:11 UT. The Cameron 2006 catalog ID=445 and the weight=5. The ALPO/BAA weight=2.
40-54W, 54N-60N i.e. nr. South? or J.Herschel 1913 Jun 15 UT 22:00? Observer: Maw (Surrey, UK, 6" & 8" refractors) "Small distinct redish spot which became diffused into a patch as term. advanced on the plateau NE of the crater South. When the plateau was on the term. (Goodacre says the crater was J.Herschel for same date -- 2 different spots or misident. for one?" NASA catalog weight=3. NASA catalog ID #345. ALPO/BAA weight=2.
Two small conical mountains, near last 4th May eruption, close to the third one that he had seen before, but not these two. They were not on any map.
SE of Langrenous 1947 Aug 28 UT 21:00? Observed by Baum (Chester, England) A long mountain mass, on limb to the SE of Langrenus crater, had a decidedly bluish cast. To the north, on the limb, were several ordinary peaks appearing in profile and some were sharp and pointed. NASA catalog ID=498. NASA catalog weight=3. ALPO/BAA weight=2.
On 2006 Jun 08 at UT 20:30-20:45 C.Brook (Plymouth, UK, 60mm refractor x75) found that Aristarchus was "shining exceptionally bright during daylight on a gibous moon". The ALPO/BAA weight=1.
Proclus 1950 Jul 27 UT 02:56 Observed by Bartlett (Baltimore, MD, USA) described in the NASA catalog as: "C.p. of Proc. disappeared)" 5" reflector used at x100, NASA catalog weight=4. ALPO/BAA weight=2.
On 2002 Sep 19 at UT 06:31-07:22 R. Gray (Winnemucca, NV, USA) found that the bright areas of the crater floor, and the east facing part of the west rim, were brighter noticeably in red (Wratten 25) or white light, than in blue (Wratten 38A). The observer suspects that the apparent TLP was more to do with the relative densities of the filters and the contrast in Aristarchus than a real event. This was partly confirmed after checks on other craters, though it did not work everywhere. The ALPO/BAA weight=1.
In 1962 Dec 09 at UT 07:36 Wildey and Pohn (Mt Wilson, CA, USA, 60" reflector) observed that Oceanus Procellarum was 1.13 magnitudes brighter than normal. Observation at sunrise and is abnormal if area measured was mare. If it were an east facing wall it would be normal. The Cameron 1978 catalog weight=5. The ALPO/BAA weight=2.
Aristarchus 1963 Oct 30 UT 01:50-02:15 Observed by Greenacre and Barr (Flagstaff, AZ, USA, 24" Clark Refractor) observed 2 ruby red spots - one just to the SW of the cobra's Head and the other on a highland area east of Vallis Schroteri. A pink colour formed coverting the SW rim of Aristarchus. Effects present with or without Yellow Wratten 15 filer. Similar effects checked for elsewhere on other craters but not seen. So presumed not to have been due to chromatic aberation or astmospheric dispersion. Effecta not seen in 12" refractor, but this may have been a resolution issue. The NASA catalog ID No. is #778. The NASA catalog weight is 5 (highly reliable). ALPO/BAA weight=4.
In 1962 Dec 09 at UT 07:42 Wildey and Pohn (Mt Wilson, CA, USA, 60" reflector) observed that Aristarchus was 0.80 magnitudes (x2) fainter than average for this age (photometric measurement) Vmag=3.80, average= 3.0. The Cameron 1978 catalog weight=5. The ALPO/BAA weight=2.
On 1992 Feb 16 at UT 01:05-01:35 P. Moore (Selsey, UK, 12.5" reflector, seeing=III) found the north rim area to be both very bright and misty - though he did not think it to be a TLP but wanted it to be recorded, just in case. The Cameron 2006 catalog ID=440 and the weight=1. The ALPO/BAA weight=1.
Herodotus 1950 Jul 27 UT 03:56 Observed by Bartlett (Baltimore, MD, USA) described in the NASA catalog as: "Pseudo c.p. in Herod. Drawings. (Similar to NASA catalog event #523)" 5" reflector used at x100, NASA catalog weight=4. ALPO/BAA weight=3.
Aristarchus-Herodotus 1970 Apr 18 UT 20:14 Observed by MacKenzie (UK,2.5" refractor x45, seeing Antoniadi I) "Fairly strong blink in a spot 1/2 way between the 2 craters. Drawing (Apollo 13 watch). NASA catalog weight=2. NASA catalog ID #1257. ALPO/BAA weight=2.
On 2002 Sep 19 at UT07:36-08:06 R. Gray (Winnemucca, NV, USA) found that Prinz was more difficlut to see through a blue Wratten 38A filter than through a red Wratten 25 filter. However he suspects that it might have something to do with the unequal (to his eyes) transmission density differences between either filter. The ALPO/BAA weight=1.
Torricelli B 2002 Oct 18 UTC 20:56-21:59 Observer: G.North (UK, 8" reflector, x134, Seeing Antoniadi IV, Transparency good) - thought that Torricelli B was perhaps a little brighter than expected, especially when compared to Moltke and Censorinus based upon past recollection of relative brightnesses at this colongitude). Slight bluish tint seen as well. The ALPO/BAA weight=1.
Aristarchus and Cobra Head 1966 Jul 30 UT 06:35-07:29 Observers Ariola and Cross (Whittier, CA, USA). NASA catalog states: "S. part of Cobra Head nr. Herodotus was a red spot; also nr. Aris. & the fork of Schroter's Valley. Variations in phenom. color, 1st on S. rim of Aris., later on N. rim. Drawings". 19" x390 reflector used. NASA catalog weight=5. NASA catalog TLP ID No. #959. ALPO/BAA weight=4.
On 1975 Feb 23 at UT 18:00-00:24 P.W. Foley (Kent, UK, 12 inch reflector, seeing Good), noticed that Aristarchus was a slate-grey tinged with blue, and abnormally bright, fading at UT 18:47, and decreased activity at UT20:45 after a cloudy period. Blue was seen on the northern wall at UT19:00, but at 19:10 no colour, but instead an obscuration. All normal from UT 21:04-21:46 according to Foley. At UT19:00 G. Amery (Reading, UK, 10 inch reflector) noted shadowy grey near the shadow under the south wall, indistinct small area, no colour. At UT 20:00 activity increased. Colour negative fr. 150-300x till 21:10 (Hunt, Cambridge, UK, 2.5" refractor, seeing Poor-Very good). Negative fr. 20:20-21:00 in bad seeing, and very good seeing at 200x all negative (colour blink filters). From 23:45-00:20UT (Fitton, Lancashire, UK, 8" reflector).

Aristarchus 1963 Oct 30 UT 05:00-08:00 Observed by Greenacre and Barr (Flagstaff, AZ, USA, 24" Clark Refractor) a violet or purple-blue colour formed beyond the NW of Aristarchus. ALPO/BAA weight=2. This followed an earlier observation that night of two red spots and a pink glow.
On 1981 Oct 11 at UT 00:05-02:00 B.Hobdell (St Petersberg, FL, USA, 4" refractor, S=3 and T=5) observed a brightening on the floor of Plato. 4 bright spots appeared and vanished and there was a fith one in the centre that was very bright at times. At UT 00:14 the central spot became bright then was "followed by a haze permeating entire floor, heaviest in the northern quadrant. Came from 2 S peaks or white spots, shaped like a boomerang extending to presumed c.p. (c.c ?). White flashed at 0052 from it cloud changed shape - spread N. At 0136 brightening from c.c. area 0419 dissipated. All white spots seen at 0200. Its outer flanks seen clearly the whole time". The above is quoted from the Cameron 2006 catalog ID=155 and weight=3. The ALPO/BAA weight=3.

On 1980 Sep 22 at UT05:00? D. Louderback (South Bend, WA, USA, 8" reflector, x140 and 2.5" refractor) observed in Promitorium Agarum that one of his pre-designated points, called "A", through to "C and "D" was at least 5 brightness points brighter in red than in blue light. The reverse was true on Sep 25th. Tonight the red seemed to be on a narrow strip on the western edge. The Cameron 2006 catalog ID=109 and the weight=3. The ALPO/BAA weight=3.
On 1994 Apr 24 UT08:15 A.T. Brakel (ACT, Australia) noticed that Mare Frigoris appeared darker than the day before. This was during a Clementine watch. The ALPO/BAA weight=1.

Aristarchus 1975 Feb 24 UTC 18:00-23:30 Observers (all in UK): Foley (Kent, 12" reflector), Gannon (Middlesex, 6" reflector), Peters (Kent, 8" reflector), Farrant (Cambridge, 8" reflector), Turner (Sussex, 8" reflector), Fitton (Lancashire, 8" reflector) - "(Foley) 1800h -- slate gray bluish on all of crater; blue at 1816h, fading at 1835h, no color on floor. At 1949h brillinance reduced, eyepiece tested at 1959h with result of elong. gray blur & afterward activity at reduced light level. Blue again at 2013h. (Gannon) at 1851h saw red tint on S.rim (instru.), neg. in white & filter lite till 2000h, (Peters) at S=P had impression of large faint blink on S.side, diffuse till 2000h, then seeing improved & saw darkish patch on S.wall -- darker in blue than red. Craters on limb were normal to 2017h, neg. at 2058h & 2130h, (Farrant) at 2000h, normal. At 2053h color in small area to W. of W. wall. (Turner) at 2230h-2300h got neg. (Fitton) at 2330h got neg. in white, seeing too poor for filters. Fitton & Farrant think obs. due to atm. effects. (activity earlier & none later confirmed)." NASA catalog weight= 5 (very good).

On 1983 Aug 22 at UT 05:44-06:33 D. Louderback (South Bend, WA, USA, 3"refractor, x150) found the brightness of Aristarchus (diffuse white patch) to be 7 to 7.5 but apparently it is normally 8-8.5, so fainter than normal. Another brightness reading found "brightening then nearly extinction at S. wall similar to changes seen on Eimmart before. Watched fluctuation compared to Cobra Head, they were similar but more pronounced at Aristarchus" especially in blue light compared to red (although there was a little brightness in red). Timings of these fluctuations were 7sec, 7sec, 9-10sec and 9-10sec. The latter two might have been seeing related as the crater enlarged up at these times. The observer felt that the Cobra Head appeared fainter than the previous year and had faded during the second set of brightness measurements. Cameron 2006 catalog ID=227 and weight=3. ALPO/BAA weight=2.
On 1983 Aug 22 at UT05:44-06:33 D. Louderback (South Bend, WA, USA, 3" refractor, x150) found that Mons Piton was still brighter in red light than in blue - the opposite was found in his July observations. The Cameron 2006 catalog ID=227 and the weight=3. The ALPO/BAA weight=2.
On 1981 Oct 12 at UT 00:00?(?) B.W. Chapman (12cm refractor, Seeing II, transparency poor, Kingston-Upon-Thames, UK) found that Mons Pico was brighter in red light than in blue. Aristarchus for comparison was the same brightness in both filters. ALPO/BAA weight=1.

On 1976 Feb 14 at UT23:35-0053 LeCroy (Springfield, VA, USA, 4.5" reflector, x75, S=6 and T=4.5). A blue haze was seen on the east side of Aristarchus and red haze on the west side. At 00:00UT details were more clear and at 00:24UT Aristarchus and Herodotus, were seperated. At 00:34UT colours were gone. At 00:35UT blue was on Aristarchus and the area was bright, but was black in a red filter. At 00:53UT the features were clear and the colour gone and the brightness had decreased to 9. Cameron comments that the colour was not due to temp. inversion because of being dark in the red filter, implying a medium). The Cameron 1978 catalog TLP ID is 1428 and the weight=1.

On 1996 Dec 24/25 at 18:12-00:02UT P. Moore (Selsey, UK, using a 15" reflector x250-360, and seeing III) saw a strong orange colour on the south wall and floor of Aristarchus. He suspected it to be spurious colour but could not detect colours on any other craters. The colour remained but at 18:12 UT he suspected a trace on colour on Mons Pico but was not sure. However he reported it to the TLP coordinator of the BAA Lunar Section. The orange in Aristarchus gradually faded and had almost vanished by 00:20UT when seeing was too bad to continue observing. At 02:30UT he was able to re-observe again and there was still a very very slight hint of orange in Aristarchus - but he comments that if he had not been looking for it he might not have noticed. ALPO/BAA weight=2.
On 1985 Sep 28 UTC 20:54-23:52 P.W. Foley (Suffolk, UK) found (actually before 20:54 UT) brightness variance in Torricelli B. J.D. Cook (Frimley, UK) observed a brief blue coloured patch somewhere in the Torricelli B region, but could not pin it down precisely. At 22:50UT M.C. Cook (Frimley, UK, 30cm reflector, seeing III - occasionally V, transparency moderate to good) Found the crater to have an elongated appearance (in SSW-NNE direction) in white light, similar to the previous night. A bright elongated spot was seen on the NNE floor, close to where the wall should be. Not able to define the rim. There was a very dark surrounding area to the crater, similar to what it was on the previous night (roughly 1/4 brightness of Censorinus). 23:04UT brighter in yellow, then red, then blue. At 23:10 it was seen that blue filter dulled the crater - this was odd because both Censorinus and Proclus were brighter in blue, which is what he would normally expect. At23:15 UT Censorinus was brighter in blue, then yellow then red filters and some orange spurious colour seen to the south of Censorinus. At 23:23UT no spurious colour seen on Proclus or Censorinus. 23:46UT Torricelli B elongated as before, but a very faint ray might have been seen to the south west of the rim. This report is not in the 2006 Cameron catalog. The ALPO/BAA weight=3.
Plato 1966 Aug 01 UT 06:14 Observed by Kelsey (Riverside, CA, USA, 8" reflector x300) The wall from the S to the NNE wouldn't focus well though at least 4 craterlets on the floor were clearly seen (Ricker uncertain if real TLP.

On 1963 Nov 01 at UT 00:20-00:35 Kopal and Rackham (Pic du Midi, France, 24" reflector) observed in Kepler an enhancement in red light at 672.5nm and 545.0nm. Luminescence ~86% +/-3% of background. The Cameron catalog says that Moore saw something between 23:30 and 03:00, but it is not clear what exactly, or whether it was Copernicus, Kepler, or Aristarchus? The Cameron 1978 catalog ID=779 and weight=5. The ALPO/BAA weight=5.
On 1963 Nov 02 at UT 00:00? Scarfe (Cambridge, UK) observed a spectral line dpeth anomaly? The cameron 1978 catalog ID=780 and weight=5. The ALPO/BAA weight=4.
On 1980 Sep 24 at UT21:34 J-J. Robinson (Teighmouth, Devon, UK, 10" reflector, x200, seeing=III) found, using a Moon Blink device, that Fracastorius blinked on the northern side in the red filter. Cameron 2006 catalog ID=110 and weight=5. ALPO/BAA weight=3.
On 1980 Sep 24 at UT 21:13-23:50 P.Moore (Selsey, UK) at 22:45 saw loss of detail in the north west wall, especially in red light, but also slightly in blue light too. By 22:48 there was activity on the crater floor i.e. the four bright spots were visible in white light but not in red. In blue the central spot was seen and there were dark radial streaks to the south wall and south east. At 22:50 there was a loss of detail. Other craters were normal. At 23:08 the floor was dark in red, but some details were visible in blue. the effect had finished by 23:35. At21:34 J-H Robinson found Plato to be normal and no blinks, though floor clearer in red than in blue, however the floor detail had gone by 21:57. Blair suspected a dusty patch in north of Plato, especially in red light. at 21:57 and it started spreading at 21:13, then east at 21:15 and then north. Though it faded at 21:25 but was back again at 21:35, and Moon blink colour filters still gave a reaction at 21:50 - the TLP remained strong until 23:50UT. The Cameron 2006 catalog ID=110 and weight=5. The ALPO/BAA weight=4.
On 1993 Mar 08 at UT 22:30 R. Titford (England, UK, 8.5" reflector, seeing=III) found a very bright white area on the northern wall, "floor < Mare Imbrium". The Cameron 2006 catalog ID=456 and weight=3. The ALPO/BAA weight=2.

Mare Crisium 1973 Mar 20 UT ~19:55 Robinson (Devon, UK) patches clearer in a red filter than in a blue filter. This is unlikely to be a TLP, more likley something to do with effects in our atmosphere, but is worth checking out, just in case. ALPO/BAA weight=1.
Aristarchus 1978 Nov 16 UTC 19:40-19:45. Observer: Mark Kidger (UK, 6" refractor x40, x133, x200, seeing poor-boiling) - saw the north wall of Aristarchus to be an electric blue. No spurious colour was seen in other craters (despite the conditions). No other observers were able to confirm this due to the weather. ALPO/BAA weight=2.

Aristarchus 1987 June 14 UT 04:43-08:00 Observed by Curtis, Jacobs, and Manske (Yanna Research Station, Carl A. Fosmark Jr. Memorial Observatory, Madison Astronomical Society, WI, USA, 17" f4.5 Dobsonian and the 8" f10 SCT Celestron) "On the night 13/14 June 11:42 P.M. to 3:00 A.M. local time or 14 June 04:43 to 8:00 UT. Three people witnessed this event and all three of them observed with three different telescopes to rule out instrumental aberration. These three pople were members of the Madison Astronomical. The three observers involved are Keith Curtis, Tom Jacobs and Robert Manske. Keith Curtis took detailed notes of the event as he observed it. The observations were made at the Yanna Research Station, Carl A. Fosmark Jr. Memorial Observatory of the Madison Astronomical Society following the annual picnic. This is MAS dark sky site and is located near Brooklyn, Wisconsin. As they were observing the night sky they saw the Moon rising and noted a strong orange color due to atmospheric effects. Approximately 1/2 hour after the Moon rise they decided to turn one of the telescopes on it. It was at 04:43 UT, it was noted by Keith Curtis that as the Moon rose it began to loose the horizon color effect and return to its normal color, but he found that the red color was not leaving the crater Aristarchus. At first they all thought this was an atmospheric effect but decided it was a real event since they detected a second crater (Euler) showing red color on its rim. Keith Curtis said that the red color was very strong on the Western rim of Aristarchus with a strong blue/green or aqua green on the Eastern rim. Keith also reported that the glow opaque enough to prevent viewing of the interior of crater Aristarchus. He said they observed until 3:00 A.M. daylight saving time or 8:00 UT. and the red glow was still visible when they ended their observing session. Robert Manske description of the event was that he saw two craters glowing a strong red and blue giving it a rainbow effect. He said that the red glow was so strong he was unable to see the craters underneath during the entire observing session. Concerning the orientation of the red and blue was on the crater he stated that he did not remember since he failed to take any notes. Concerning whether there was any difference in appearance when they observed it with the 17" f4.5 Dobsonian and the 8" f10 SCT Celestron. He said that he could not detect any difference to the lunar formation or the color on it regardless of which telescope he used. He did mention that as the Moon was rising it had the appearance of one large Maria in the center of the disk. This illusion disappeared as the Moon rose higher into the sky. When talking to Tom Jacobs he said that he remembered that he did not see anything on the Moon until 1/2 hour after Moon rise. He said that he remembered that the entire Aristarchus region had a strong reddish or pinkish color. All three witness all reported variations in the type of color they were seeing. This would indicate that individuals color perception is a major factor during a color event. Keith Curtis saw a very strong coloration around the rim of the craters, where Robert Manske saw the entire region covered by this red and blue coloration and he could not see the interior of the craters underneath. Tom Jacobs reported that the glow covered the entire crater but he could see the crater underneath it. The Moon never achieved a height greater than 21 degrees so it could be that what the observers saw was caused by the Earths atmosphere. Further details can be found on the following web site: http://www.ltpresearch.org/ltpreports/ltp19870614.htm " ALPO observational report. Cameron 2006 catalog ID=303 and weight 5. ALPO/BAA weight=3.

Nothing unusual seen by M.Cook at 23:52UT or by A Cook at 00:40-00:52 and indeed other craters did appear to have shadows this far from the terminator ? so perhaps only unusual aspect of the original observation that could not be checked due to poor seeing by the latter observer was the fuzziness.

On 1979 Nov 09 at 10:30-11:05UT D. Louderback (South Bend, WA, USA, S= 4-2/10, T=P) detected a rapid fade in brightness of south and north sunlit slopes of Mons Piton. Then the western flank faded and became obscured in detail. The variations detected were approximately 5 sec in duration, where as seeing effects were of the order of 15 sec. Mons Pico and other mountains did not show a similar effect. "It was seen only in viol. filter tho once seemed blurred in red. No changes, dimming was like a veil of mist covering the mtn - swiftly, then dissipating as rapidly. Sketch. Phenomenon went on & off till 11:00UT. Cloud was cir. In viol & spreadover mtn in 2s. Saw 6 rapid, spinning motions within the cloud like an explosion or tornado seen from above. Blurring in red was more elongated. Motion across it was like a heat wave. Whole event lasted ~35m but disappeared in a few secs. Albedos 7.4 cp, 7.5 pt A, 7 pt B." Cameron 2005 catalog ID=75 and weight=4. ALPO/BAA weight=3.
