2020-Aug-01 UT 01:16-01:17 Ill=93% Vallis_Schroteri observed by Weier_D on 1992-3-16

     On 1992 Mar 16 at UT 00:39-01:14 D. Weier (Sun Praire, WI, USA, 11" 
     reflector) at 00:39UT noted some soft, diffused, faint ďllumination 
     within the shadow projected over the Cobra Head area, though it had a 
     sharp appearance to the edge of the shadow. D. Darling (Sun Praire, WI, 
     USA, 11" reflector) was taking photographs from UT 00:51 and making 
     drawings and visual descriptions. The first 3 photographs in the 
     sequence have the crater as normal. Four other photographs reveal an 
     abnormality. Seeing conditions were excellent and a great deal of 
     surface detail was seen inside Aristarchus crater - however the 
     apeparance of the Cobra's Head was "washed out" and again shadows near 
     to this were illuminated. The NASA catalog ID=442 and the weight=5. The 
     ALPO/BAA weight=3.

     Dungan (Flagstaff, AZ, USA, 24" refractor) observed a deep violet 
     area form on the western exterior of Aristarchus, and a less deep 
     violet area form to the eastern edge of Aristarchus. As these 
     were becoming stronger, a blue-like haze formed on the sunlit 
     floor of Aristarchus, that obscured underlying detail. The 
     ALPO/BAA weight=2.

     On 1997 Oct 13 at UT11:09-11:21 D. Rodway (Oamaru, South Island, New 
     Zealand, 8.5" reflector, x270) saw a deep salmon-pink colouration in 
     the south east corner interior of the crater Aristarchus. This colour 
     was confirmed by the observers wife. By 11:21 UT the colour had faded 
     completely. Rodway had been a lunar observer since 1958, using a wide 
     range of instruments from 3 inch refractors to 12 inch reflectors and 
     had observed a TLP in Gassendi back in 1966 (from L'ondon, UK), and so 
     was an experienced observer. The ALPO/BAA weight=4.

     features, one on the southern floor of the crater, and another 
     just slightly to the NW of the centre. on the southern 
     floor of the crater. Lena suspects a combination of seeing 
     effects and albedo markings on the floor. However this effect of 
     two spots on the floor has not been repeated again.For further

     3" refractor, x150, seeing poor and chromatic aberation on the limb) 
     detected "purple"in the vicinity of Aristarchus crater and this was 
     stongest on the north and north west external rims, however there was 
     no "violet glare"from inside the crater. However the region of the 
     central peak was very bright - though he could not detect the central 
     peak. The brightness of the TLP was 4.5 and it should normally be 3 
     (nimbus area). Near the "big plain"it was 7. The chromatic aberation 
     seen on the crater. There was also violet on the northen wall of 
     Herodotus crater and the Cobra Head. Ďt appeared dark blue in the blue 
     filter", the surrounds remained gray". Apparently on the 26th the"ring 
     was still dark with faint violet - nearly normal". Cameron comments 
     that the TLP was due to spurious colour. The Cameron 2006 catalog ID=

     weight=4.


2020-Aug-06 UT 05:41-07:38 Ill=93% Aristarchus observed by Foley_PW on 1983-10-23

     Aristarchus 1983 Oct 23 UT 19:00-01:30 Observer: Foley (Kent, UK, 
     12" reflector, seeing=II) noiced at 19:00UT an extended bright 
     spot on E wall and extending beyond. This was brighter than other 
     areas of the crater. There was also occasional star-like 
     glistening. Foley comments that the inside of Aristarchus was 
     slightly obscured. The TLP started fading from UT20:30 and 
     finished by 01:30UT. six out of nine independent observers 
     confirmed the effects seen. In total 14 observers observed, 9 
     reported back and 6 found abnormalities in Aristarcus though all 
     encountered variable seeing conditions - some had spurious 
     colour. Cameron comments that this was one of the best 
     recorded/confirmed TLP events. All CED brightness measurements 
     obtained were very high. Moore, Nicolson and Clarke (5" refractor 
     and 15" reflector, 230-350xseeing III) found the crater to be 
     very bright at 19:11UT through a 5" refractor and there was a 
     blob on the east rim (Bartlet's EWBS?) at 19:14UT. Nicolson also 
     saw a very bright star-like area on the eastern wall but this was 
     not defined as it usually is. The crater was also very bright at 
     22:43UT using the 15" reflector available to these observers. At 
     01:07UT they used a Moon blink and discovered that the bright 
     region was bright in blue light and less bright in red - although 
     this was not a detactable blink when switching rapidly between 
     filters. They found that the crater had returned to normal by 
     01:15UT. M.C. Cook (Frimley, UK, seeing III-IV) observed a large 
     diffuse spot on the east of the crater that was brighter in blue 
     than in red light and the CED device gave a high reading. J.D. 
     Cook (Frimley, UK, seeing III-IV) made a skecth that showed the 
     bright spot extended on the east wall - again the CED reading was 
     high and a lot of detail was visible on the floor. A.C. Cook 
     (Frimley, UK, seeing III-IV) also noted remarkable detail and the 
     bright (as confirmed by CED) blob on the eastern rim. G. North 
     (Sussex, UK, seeing III-II) also confirmed the bright blob on the 
     eastern wall. Wooller found the north west wall was a dirty 
     yellow colour - though no colour was seen elsewhere in or outside 
     the crater. Mosely found the crater to be bright and his sketch 
     revealed the extension of the bright blob on the eastern rim and 
     again a great deal of interior detail. Amery (Reading, UK, seeing 
     III) found Aristarchus to be "a brilliant splash against dulled 
     background in violet filter, especially polarizing filter. CED + 
     polarizer readings high, but not as high as previous night". 
     Mobberley (Suffolk, UK, seeing III-IV) remarked that "spurious 
     colour a total mess around Aristarchus & nothing abnormal seen". 
     A photograph was taken at 20:50UT reveals the  bright blob and 
     entire detail. Peters (Kent, UK, seeingIII-II) observed  
     Aristarchus with a UV screen from 20:15-21:23UT and comented that 
     althogh being very bright, there was no variation between white 
     and UV. It was checked with a Moon Blink device and the radial 
     bands were  clearly seen in white light, < in blue. The Cameron 
     2008 catalog ID=233 and the weight=5. The ALPO/BAA weight=4.

2020-Aug-06 UT 05:58-07:28 Ill=93% Aristarchus observed by Brook_C on 2002-9-23

     On 2002 Sep 23 at UT22:45-23:56 C. Brook (Plymouth, UK) noticed that 
     the bands inside Aristarchus varied (UT22:45-22:56) in definition 
     whilst the rim of Herodotus and the rays of Kepler and Copernicus 
     remained sharp. These bouts of variation were 1-2min in duration. At 
     23:56UT when he checked again the periodic blurrings of the bands were 
     still present. The observer suspected atmospheric effects. M.Cook 
     (Frimley, UK) observed 22:00-22:30 and could see only 2 bands on the 
     west wall - but this may have been because of poor transparancy. The 
     ALPO/BAA weight=1.

     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 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.

2020-Aug-23 UT 00:24-01:13 Ill=20% Aristarchus observed by Fryback_D on 1988-4-21

     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

2020-Aug-24 UT 00:23-01:42 Ill=31% Aristarchus observed by Pruss on 1969-7-19

     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 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.

     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.


2020-Aug-24 UT 00:36-01:42 Ill=31% Aristarchus observed by Gervais on 1969-7-19

     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

     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.


2020-Aug-24 UT 01:04-01:42 Ill=31% S_Pole observed by Kemp_A on 2011-4-8

     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.

     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

     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.


2020-Aug-26 UT 00:41-02:32 Ill=53% Theophilus observed by Fox_WE on 1969-7-21

2020-Aug-26 UT 00:49-02:37 Ill=53% Promontorium_Agassiz observed by Green_J on 1991-5-21

     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.

2020-Aug-27 UT 00:19-01:28 Ill=64% Ross_D observed by Harris on 1965-9-4

     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

2020-Aug-27 UT 01:42-03:21 Ill=64% Theophilus observed by Cook_JD on 1978-11-8

     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.


2020-Aug-28 UT 00:17-00:48 Ill=74% Tycho observed by Abel_P on 2009-5-3

     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.


2020-Aug-28 UT 00:29-02:26 Ill=74% Copernicus observed by Burt_G on 2006-6-5

     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.

2020-Aug-29 UT 04:40-06:54 Ill=84% Campanus observed by Bush_S on 2014-1-11 *

     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 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

2020-Aug-30 UT 02:50-04:46 Ill=90% Herodotus observed by Fabian on 1989-5-17

     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. 


2020-Aug-30 UT 04:52-06:10 Ill=91% Gassendi observed by Foley_PW on 1978-1-20

     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

2020-Aug-30 UT 05:24-06:10 Ill=91% Aristarchus observed by Fitton on 1975-2-22

     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

     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.

     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

2020-Aug-31 UT 01:28-03:15 Ill=95% Aristarchus observed by Greenacre on 1963-10-30

     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.


2020-Aug-31 UT 01:28-02:58 Ill=95% Aristarchus observed by Gray_R on 2002-9-19

     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.

     reflector) observed that Oceanus Procellarum was 1.13 magnitudes 
     brighter than normal. Observation at sunrise and is abnormal if area

2020-Aug-31 UT 01:42-02:59 Ill=95% Aristarchus observed by Wildey on 1962-12-9

     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.

     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)"

     weight=3.


2020-Aug-31 UT 01:49-03:20 Ill=95% Langrenus observed by Moore_P on 1992-2-16

     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.


2020-Aug-31 UT 02:06-04:03 Ill=95% Prinz observed by Gray_R on 2002-9-19

     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.

2020-Aug-31 UT 03:20-04:39 Ill=96% Torricelli_B observed by North_G on 2002-10-18

     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.


2020-Aug-31 UT 04:19-06:15 Ill=96% Aristarchus observed by Foley_PW on 1975-2-23

     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). Turner of Sussex, UK with an 8" 
     reflector, observed as well. (confirm. of activity earlier & neg. 
     later). Cameron 1978 catalog ID=1397 and weight=5. ALPO/BAA weight=3. 


2020-Aug-31 UT 04:27-06:24 Ill=96% Aristarchus observed by Greenacre on 1963-10-30

     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.


2020-Aug-31 UT 04:55-06:51 Ill=96% Plato observed by Hobdell on 1981-10-11

     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. 


2020-Aug-31 UT 06:35-07:20 Ill=96% Promontorium_Agarum observed by Albert_J on 2015-11-24

     Promontoroum Agarum. On 2015 Nov 24 UT 00:50-01:15 J. Albert 
     (Lake Worth, FL, USA, Celestron C11, x224, seeing 4/10, 
     transparency = 3rd magnitude) observed that this feature was 
     slightly brighter through a red Wratten 25 filter than 
     through a blue Wratten 44a filter. ALPO/BAA TLP weight=2.
