In 1940 Dec 02 at 00:00? Vaughan (Des Moines, Iowa, USA, 3" reflector) observed Aristarchus in the dark part as a bright spot. The cameron 1978 catalog ID=480 and weight=2. The 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.

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.

On 1968 May 02 at UT 01:20-02:14 Doughty (Red Bank, New Jersey, USA, 8" reflector, x120) observed a bright area in Aristarchus, surrounded by a faint glow. May have been atmospheric dispersion. Glow fainter at 01:56UT and imperceptible at 02:14UT. Kelsey and Ricker consider the observation abnormal. The Cameron 1978 catalog ID=1070 and weight=3. 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.

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 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.
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???

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). Ringsdore confirmed. (Apollo 11 watch)" Confirmed by Baum 21:00-21:20UT. NASA catalog weight=5. NASA catalog ID No. 1166. 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 1975 Dec 08 at UT18:00-20:40 P.W. Foley (Wilmington, Kent, UK, 12" reflector, x60-x624, seeing II, slight mist) found Aristarchus to be less well visible than features such as: Grimaldi, Reiner, Darwin/Byrgius, Kepler, Plato and Sinus Iridum. Earthshine was exceptionally good tonight and was orange/red in colour. Photographs were taken and these confirmed the apparent dullness of Aristarchus. 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. Apparently Gassendi can often show up red colours (according to Cameron) but rarely is this seen in Earthshine. Foley saw the sketch and suspects that the location was Gassendi. The Cameron 1978 catalog ID=397 and weight=2. The ALPO/BAA weight=3.
Alphonsus area? 1949 Jun 01 UT 22:06 H.P. Wilkins (Kent, UK, 6" reflector x200) observed a bright white 1 sec stationary (mag 3?) flash in Earthhsine, close to the central meridian, and due E of Theophilus (potentially in the general area of Alphonsus?). The flash was approximately 6 km in diameter. ALPO/BAA weight=1.
On 1970 Apr 11 at UT 22:04-23:00 Claudio Pamplona and Jackson Barbosa(Fortaleza, Brazil, 2" refractor, x160, seeing=fair) observed an obscuration over Peirce, in particular they could not see the crater wall and the crater itself was like a black pit. (Apollo 13 watch). The Cameron 1978 catalog ID=1238 and weight=1. The ALPO/BAA weight=1.
On 1991 Jun 17 at UT 20:30 T. Castro (Sao Paulo, Brazil, 24" reflector, x500) observed "Large white spot with tail eastward shore of M. Crisium." The effect was seen on several nights but had faded completely by 20th June. Tonight it varied in brightness from "7.5-9.5 albedo" The Cameron 2006 catalog ID=430 and the weight=5. The ALPO/BAA weight=1.

On 1969 Jul 20 at UT 19:55-20:10 Delaye, Thinon, Donas, and Jourdran (Marseilles, France, 10" refractor, x60) saw between 19:55-20:04UT Aristarchus to be bright and in it pulsations with 10 sec duration. 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.
Atlas 1969 May 22 UT 21:20-21:40 Observed by Germann, Wild, Vieli (Zurich, Switzerland, 6" reflector) "Rim towards the sun was bright. Part of time was interrupted. (Apollo 10 watch)" NASA catalog weight=3 (average). NASA catalog ID #1135.

On 1984 Jul 05 at UT 00:00-01:25 Marshall (Medelin, Columbia) found Proclus to be much brighter than Censorinus (which of the two was abnormal is a question) - though he thought that Censorinus looked dull. The Cameron 2006 catalog ID=247 and weight=3. The 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.
On 1970 Apr 12 at UT 22:10-22:40 Censorinus was observed by Jean Nicolini (Sao Paulo, Brazil, 12" reflector, x680). The crater had a visible reddish hue--gap in bright area on western slope. Colourless to pink to reddish. Environs also involved. Photographs were taken. (Apollo 13 watch). Cameron 1978 catalog TLP ID 1241 and weight=3. ALPO/BAA weight=3.
On 1969 Jul 20 at 22:50-23:15UT Jean Nicolini (Sao Paulo, Brazil, 12" reflector x430, S=II.5-III.5) saw a weak reddish area on the north west(east?) wall of Eudoxus crater. An English Moon Blink device showed it dark in blue and opaque in red. Reddening remained unchanged while comparing it to adjacent region and Aristotles. Colour index was toward dirty orange. Colour most apparent in the good moments of seeing and disappeared in the poorer moments of seeing, Cameron says that this is opposite to what was expected if the effect was atmospheric in origin and no colour was seen in Aristotles. Apollo 11 watch. Cameron 1978 catalog ID=1177 and weight=3. The ALPO/BAA weight=3.
Proclus 2005 Jun 13 UT 16:00-17:10 Observed by Julio Lobo (Campinas, Brazil, 500mm telescope + finder scope) "Glow and reddishness (pink) seen on circular rim. Also crater was intensely bright all over. After 16:30 the brightness fades, returning to normal. The ALPO/BAA weight=3.

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.

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.
Fracastorius 1975 Apr 19 UT 19:47, 20:40, 20:45 Observed by Robinson (Teignmouth, UK, 26cm reflector) "Fracastorius had a blink - it was bright in red and darker in blue at these three times, and probably in between. This was possibly natural surface colour being detected?". ALPO/BAA weight=1.

On 1975 Apr 19 UT 21:09 P. Foley (Kent, UK), detected blue in Plato on east. Fiton at UT20:45 found blue along the south wall at the east (IAU?) end, which was very bright white. Blueness extended towards the large landslip at the east of the formation. Immediately north of the landslip, where the bright wall curves first westwards, then again northwards, red could be faintly detected, folloowed by a very faint blue. All other parts of the formation were normal. Examination with a Moon blink device revealed no colour blink. J-H Robinson also found blue, with red on the west wall (exterior?). By 21:30UT Fitton found Plato to be normal and so was Proclus, though he did find Epigenes (bright cresecent of east wall only) slightly blue to the N.W and red to the S.E. Mare Crisium was normal. Prominent spurious colour seen on Venus, but it was low in the sky, with blue to the north and red to the south. However J.H. Reading, managed to see the north east floor blurred and slightly blue from 22:45-23:00UT. These reports are BAA observation. The ALPO/BAA weight=2.

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.
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.

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.
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 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.
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.
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 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=2.
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.

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.
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.

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.
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 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).
