     On 1964 Feb 02 at UT08:30-09:40 G.Reneau and B.Crowe (2.4" 
     refractor, x90)observed Ross D to be double. This was during a 
     time when observers were looking for a Ranger crash plume. The 
     Cameron 1978 catalog ID=799 and weight=1. The ALPO/BAA weight=1.


2023-Nov-02 UT 04:22-06:19 Ill=79% Aristarchus observed by Marshall_KP on 1983-5-31

     On 1983 May 31 at UT03:45-04:30 K. Marshall (Medellin, Columbia) noted 
     that the whole area of Aristarchus, Herodotus, and Schroter's valley 
     was both blurred and violet. There was hardly any detail seen inside 
     the crater. Herodotus could hardly be seen either and Schroter's valley 
     was totally unrecognizable. A sketch was supplied. The Cameron 2006 
     catalog ID=223 and the weight=3. 


2023-Nov-02 UT 04:58-06:23 Ill=79% S_Pole observed by Unknown_Observer on 1895-9-8

     On 1895 Sep 07 an unknown observer (Lewis Swift?) observed a pale blue 
     segment on the upper limb - this was apparently confirmed by Faulkes 
     (Mem. BAA, 1895). Cameron says that this is probably 1895 Sep 08 at UT 
     06:00 as Sep 07 is local time. She also infers that "upper limb" is the 
     southern limb and that Swift was at the Lowell Observatory, Flagstaff, 
     AZ, USA. The Cameron 1978 catalog ID=285 and weight=5. The ALPO/BAA 
     weight=2.


2023-Nov-02 UT 23:11-00:01 Ill=72% Aristarchus observed by Louderback_D on 1991-7-31

     On 1991 Jul 31 at UT 07:50 D. Louderback (South Bend, WA, USA, 3" 
     refractor) observed that the south floor of Aristarchus was wellow - 
     "almost gold, spilled over S wall on ray toward Herodotus". Cameron 
     comments that Bartlett often reported a yellow floor but not a spill of 
     the colour over to the external ray. Cameron also comments that 
     Louderback's refractor would refract more in blue light than in yellow, 
     therefore she did not think that it was due to chromatic aberation. The 
     Cameron 2006 catalog ID=431 and the weight=3. The ALPO/BAA weight=2. 


2023-Nov-02 UT 23:11-00:01 Ill=72% Mons_Piton observed by Louderback_D on 1991-7-31

     On 1991 Jul 31 at UT 07:50 D. Louderback (South Bend, WA, USA, 3" 
     refractor) found that all of Mons Piton was "unusually dark". Points D, 
     C (E and S resp), usually brightest points, but this time were not 
     bright. "Whole mt was as dark as W wall usually is at this time. In 
     violet filter Piton disappeared completely, but was a little brighter 
     in red filter and points D & G showed. Color not seen by eye. No albedo 
     measured. Suggests red event." Cameron rules out chromatic aberation 
     from Louderback's refractor. The Cameron 2006 catalog ID=431 and the 
     weight=3. The ALPO/BAA weight=1.


2023-Nov-03 UT 03:30-04:03 Ill=71% Aristarchus observed by Rule on 1973-11-15

     Aristarchus 1975 Nov 15 UT 06:34 Observed by Rule (Edinburgh, Scotland,

     the whole of Aristarchus to be a strong violet color. No 
     colour was seen elsewhere on the Moon. The Cameron 2006 
     catalog ID is 272 and the weight is 2. The ALPO/BAA 
     weight is 2. 


2023-Nov-03 UT 05:48-05:58 Ill=70% Torricelli_B observed by Foley_PW on 1985-5-9

     On 1985 May 09/10 at UT 22:50-03:10 P.W. Foley (Kent, UK) found that 
     Torricelli B was very bright in Earthshine and was blue in colour. The 
     Cameron 2006 catalog ID=272 and the weight=2. The ALPO/BAA weight=2.


2023-Nov-04 UT 02:21-02:36 Ill=62% Plato observed by Foley_PW on 1975-6-29

     Plato 1975 Jun 29/30 UT 23:05-00:30. Foley (Wilmington, UK, 12" 
     reflector, seeing, III, good clarity transparency). At 23:05, 
     blue was seen on the inner wall:floor southern boundary, and red 
     on the corresponding northern floor:wall boundary. However by 
     00:30, blue was now on the W floor:wall boundary, and red on the 
     E floor:wall boundary. Atmospheric spectral dispersion existed 
     in many regions, but did not change like the colours in Plato. 
     Similar appearance craters such as Grimaldi, Schickard, and 
     Riccioli, were checked for a similar change in colour, but no 
     change was noticed in these. ALPO/BAA weight=1.


2023-Nov-04 UT 04:53-07:10 Ill=61% Aristarchus observed by Moeller_J on 1987-10-13 *

     On 1987 Oct 13 at UT14:00-17:00 J. Moeller (Kirkville, NY, USA, 
     6" reflector) observe and 10x70 binoculars) noted that 
     Aristarchus was brilliant in the sky and the most striking 
     feature on the lunar surface (2-3x brighter than Tycho). It 
     appeared as a hazy white cloud at first. The effect lasted for 3 
     hours. The Cameron  2006 catalog ID=309 and the weight=1. The 
     ALPO/BAA weight=1.


2023-Nov-04 UT 05:04-05:15 Ill=61% Aristarchus observed by Price_M on 1980-7-3

     Marcus Price (Camberley, Surrey, UK) noted that Aristarchus
     was extremely bright. A 6" reflector was used. The Cameron 
     2006 Catalog ID is #98 and the weight is 1. The ALPO/BAA weight
     is 1 too.


2023-Nov-05 UT 01:08-00:00 Ill=52% Plato observed by Moore_P on 1991-12-28

     On 1991 Dec 28 at UT 02:10 P. Moore (Selsey, UK) could see no detail on 
     the floor of Plato crater. This report needs to be read in context with 
     the comments by Cameron for A.C. Cook's observation of the floor of 
     Plato on 1992 Jan 18 - Cameron 2006 catalog ID=438.


2023-Nov-05 UT 02:23-03:13 Ill=52% Pitatus observed by Unknown_Observer on 1974-6-12

     On 1974 Jun 12 at UT0256 an unknown observer noted a dark blob on the 
     northern edge of the floor of Pitatus crater.

     127mm rich field refractor, seeing III, transparency Good) 
     observed that the northern half of Grimaldi seemed much lighter 
     than the southern half. She comments that she has seen this 
     before in last quarter phases, but it was really quite marked 
     how lighter the northern half was on this occasion. The ALPO/BAA 
     weight=1.


2023-Nov-07 UT 03:04-06:43 Ill=32% Earthshine: sporadic meteors

     On 1989 Feb 10 at UT 19:00? D. Holmes and Wooler (Lancashire, UK) found 
     area near Prinz to be bright, but so too was Aristarchus crater.  The 
     Cameron 2006 catalog ID=350 and weight=3. The ALPO/BAA weight=1.


2023-Nov-17 UT 17:18-17:48 Ill=21% Proclus observed by Edmonds on 1989-2-10

     On 1989 Feb 10 at UT 19:00? Edmonds (England) observed a 
     "bright red coppery" colour in the northwestern part of 
     Proclus crater. He checked and found that there was no colour 
     elsewhere, though he still suspects that the effect was 
     spurious colour. Cameron comments that usually blue 
     is seen in the north and red in the south if due to spurious 
     colour. The Cameron 2006 catalog ID=350 and the weight=3. The 
     ALPO/BAA weight=1.


2023-Nov-17 UT 17:51-19:41 Ill=22% Earthshine: Leonids: ZHR=15 vel=71km/s

2023-Nov-18 UT 17:17-18:54 Ill=31% Aristarchus observed by Cook_JD on 1981-3-11

     A faint white pinpoint flash seen and also in the same position
     a whitish glow around the crater. No futher flashes seen after the
     first one. From UT2117-2130 the glow was still visible but faded
     making it more difficult to locate. When Foley observed he found 
     Aristarchus not very visible in Earthshine, despite Plato, Grimaldi,
     and several other features being visible. Both observers used
     12" reflectors. Cameron's 2006 catalog Extension ID=124 and 
     weight=0. ALPO/BAA weight=3. 


2023-Nov-18 UT 17:17-17:54 Ill=31% Aristarchus observed by Miles_H on 1985-4-25

     On 1985 Apr 25 at UT 21:34-22:04 H. Miles (England) observed 
     Aristarchus within Earthshine. Foley (Kent, UK, 12" reflector) had 
     observed it one hour prior to Miles and found it to be both dull and 
     blue - with a bright patch west of the crater on Aristarchus Upsilon 
     Mountain. At 21:45UT 6 star-like flashes seen on the floor. They 
     occurred again a few minutes later and repeated at 22:04UT.By 21:45UT 
     the bright patch had gone though. Smith (England) had also apparently 
     seen the flashes and a further glow, albeit more north of the one seen 
     by Foley. Miles confirmed Smith's glow north of Aristarchus. 
     Peters did not see much, indeed found Aristarchus to be quite 
     faint (2130-2141). The Cameron 2006 catalog ID=264 and the 
     weight=3. The ALPO/BAA weight=2. 


2023-Nov-18 UT 17:17-17:54 Ill=31% Torricelli_B observed by Cook_MC on 1985-4-25

     Curious lack of detail, but this may have been related to
     the seeing. Of greater interest though was a dark blue
     splodge where the crater should have been. Shadow seen through
     this splodge, but no crater rim seen.

     On 1981 Mar 12 at UT 19:25-20:30 Butler (of Brixton, UK, using a 
     10" reflector at 32-64x) noticed that Aristarchus was not 
     visible, although the Earthshine was very obvious. Foley (of 
     Kent, UK, and using  12" reflector) noticed that the crater was 
     only just visible but Plato could definitely be seen. Cameron's 
     2006 TLP extension catalog ID=125 and weight=0. ALPO/BAA

     On 1789 Sep 26 at UT 03:30 Schroter (Lillienthal, Germany) observed 
     close beneath Mons Blanc at the west foot, in the dark, a small 5th 
     magnitude, speck of light. Its round shadow was sometimes black, 
     sometimes grey. Cameron suspects that this is the same as her TLP 
     report No. 50. the Cameron 1978 catalog ID=62 and weight=4. The 
     ALPO/BAA weight=3.

2023-Nov-20 UT 17:16-17:53 Ill=53% Werner observed by Lippert_RM on 1953-9-16

     On 1953 Sep 16 UT03:00 R.M. Lippert (San Diego, CA, USA, 20cm 
     Cassegrain reflector, x90)saw a bright magnitude 1 flash on the 
     Moon, that was probably on the east rim of Werner(?) crater. It 
     is unclear if the observer meant it was really magnitude 1, or

     On 1973 Dec 02 at UT 22:17:33 Barrett and Brick (New York, 3.5" Questar 
     freflector) observed an occultation of Kappa Aquari, a wide double 
     star, on the western limb. The star faded perceptably before 
     disappearing. Cameron says that the fact that the star was a double was 
     not an explanation - she says that there are many reports of similar

2023-Nov-21 UT 18:04-19:24 Ill=65% Tycho observed by Spellman_R on 1996-4-27

     1996 Apr 27 UTC 02:26-03:14 Observed by Spellman (Los Angeles, CA, USA)
     " 02:26 U.T. Sunrise on Tycho 3/4 of the crater was in shadow, 
     topmost section of the central peak was in sunlight. In white light 
     brightness of the central peak rivaled the brightness of the Eastern
     (sunlit) wall. No change was detected in red light, however in blue 
     light definite strong darkening was observed. Blink obtained when 
     viewing thru 25A and 38 filters. At 2:52 U.T. in the poor to fair 
     seeing the apparent size of the central peak in white and red light was 
     the same, in blue light the central peak in white and red light was the 
     same, in blue light the central peak size shrank to 1/2 white and red 
     size (and brightness). Also appearing sharper. Comparison was made also 
     with the central peak of Alphonsus, no changes were observed. The 
     significant part of the observation was the relative brightness of the 
     central peak to the sunlit rim in white and red light, they appeared 
     almost identical with the crater rim, being just slightly brighter. In 
     blue light the brightness of the central peak was reduced by at least 
     half while the rim brightness was not, (relative to one another). I 
     strongly believe that this was a real event. The shadow filled 
     portion of Tycho was examined for any abnormalities but none 
     were observed. Observations were ended shortly after 3:14 U.T. due to 
     clouds. I also conducted about 20 Moon blink observations during this 
     observing run and got the same strong reaction each time." ALPO/BAA

2023-Nov-21 UT 21:43-23:32 Ill=66% Aristarchus observed by Madej_P on 1984-12-31

     Although the crater was on the night side, a small bright spot
     was seen. This was blue, almost UV, and equivalent to a star of
     magnitude 2. It flashed over intervals of about 30 seconds
     and changed in colour from UV to blue. The BAA Lunar Section
     TLP network was alerted. Mobberly and J.Cook did not see much
     although J. Cook may have seen something, but located else where?
     Cameron lists this as a confirmed? observation? The Cameron

     (Rodewisch, East Germany) was taking a sequence of images 
     during the impact of the Soviet Lunik 5 (upper stage of the 
     carier rocket?). He  detected a tens of km scale elongated 
     cloud after the impact over a duration of 9.5 minutes. This 
     was near to Deslandre crater. However there are differences 
     between the images elsewhere on the Moon, possibly due to 
     different exposures or some other effects and it is not 100%

     Aristarchus Area 2004 Nov 22 UT 04:58-05:49 Observed by Gray 
     (Winemucca, NV, USA, 152mm f/9 refractor, seeing 4-5, trasparency 4-5, 
     x114, x228) "Blinked Herodotus with Wratten filters Blue 38A and Red 
     25. The illuminated west crater wall stood out brilliantly in blue 
     light, much more so than in white light. This was true also of 
     Aristarchus. Red light did not increase contrasts in Herodotus any more 
     than they were in white light. Shadows in Herodotus appeared as black 
     as the night west of the terminator and remained that way throughout 
     the observing period. No TLP seen in Herodotus tonight. A possible TLP 
     was seen to the west of Herodotus near the terminus of Schroters 
     Valley. It was noted at the beginning of the observing period that 
     there were four very bright spots of light, one near the end of 
     Schroters Valley, the other three grouped together a little farther 
     north. Although not far from the terminator they were definitely east 
     of it. It was noted that all of them nearly vanished in the Blue 38A 
     filter while Aristarchus and the rim of Herodotus gleamed brilliantly. 
     At 5:19UT it was noted that the most brilliant of the four lights, the 
     one near the terminus of Schroters Valley, had faded almost to 
     invisibility in white light. When first seen it had been brighter than 
     Aristarchus. It remained very dim after this through the remainder of 
     the observing period, and was unchanged at 7:35-7:49UT when I again 
     examined the area. The other three bright spots remained brilliant and 
     unchanged."

     On 1984 Feb 14 P. Moore (Selsey, UK) observed that Plato was darker 
     than the nearby mare and no detail could be seen on the floor or the 
     eastern wall - the later was obscured. At 23:40UT some dimming was 
     still present on the north east wall and still no detail on the floor 
     of Plato. Cook noticed that the eastern floor close to the wall was 
     misty and also noted no detail on the floor. Amery though noted that 
     all parts of the floor were sharp although some darkening was visible 
     in the north west and a hint of obscurtion. The east wall though was 
     quite sharp. Mosely could see the central craterlet but from 8-6

2023-Nov-25 UT 22:14-00:09 Ill=97% Plato observed by Foley_PW on 1978-8-16

     Peter Foley (Kent, UK, 8" reflector, seeing=II) noticed that
     the floor beneath the north wall, and the area over the north
     wall were indistinct (almost out of focus). Despite looking
     elsewhere in the crater and surrounds, no other blurring
     (obscuration of detail) could be seen, indeed everywhere else
     was sharp and detailed. Foley tried several eyepieces but this
     made no difference. He used a crater extinction device but
     found no variations in brightness. There was a slight
     darkening when he used a red filter in the Moon Blink device.
     The obscuration effect weakened between UT20:56 and 21:10,
     was difficult to see at 21:13 and had finished by 00:15.
     Patrick Moore (12" reflector, Dublin, Ireland) saw nothing

     On 1980 Apr 28, Louderback (South Bend, WA, USA using a 8" reflector 
     and a 2.5" refractor) observed a very bright reg region on top of the 
     south west rim of Aristarchus crater. This was on the same side as the 
     ray system between Aristarchus and Herodotus. Louderback noticed some 
     chromatic aberation - blue where he had seen the red patch before.
     Louderback suspects chromatic aberation was the cause although did not 
     see red in that region ever again. "Patch was between his observation 
     points A and C. Point C was 5 points brighter in the red filter than in 
     the blue." A sketch was made. Cameron suspects that the TLP was real.

2023-Nov-25 UT 23:32-01:07 Ill=98% Aristarchus observed by Louderback_D on 1985-12-25

     Louderback observed that the south west wall was a creamy deep yellow.
     There was also strong fluorescent blue on the west wall of the Cobra
     Head - Schroter's Valley area and this was similar to the violet glare
     seen on Aristarchus at times. Violet was seen between Aristarchus and
     the Cobra Head. Seeing coditions were poor. Brightening of a point
     near C occurred roughly every 10-15 seconds and lasted 0.5 sec -
     (Cameron concludes that this was not due to the Earth's atmosphere).
     A 0.2 step drop in brightness was seen on point A (twin spots).
     Point C had reduced by 0.6 steps. Elsewhere was stable in brightness.

     Aristarchus normal in red and blue filters however the
     Cobra Head part of Schroter's Valley was brighter in blue.
     Indeed it was very dull in red - Louderback says that this
     was not surprising as the whole areas around Aristarchus is
     brighter in blue. Louderback is an experienced observer

2023-Nov-27 UT 23:04-00:42 Ill=99% Aristarchus observed by Darling_D on 1989-10-15

     David Darling observed bright glittering on Aristarchus. This
     was followed by a flare up in brightness at 00:38:05 UT in the
     comet-like ray area of the crater equivalent in intensity to the
     central peak. Then he saw another one on the north east rim of 
     Aristarchus of the same brightness. A third flare was seen at
     00:49UT in south of Herodotus, on the comet-like ray. Another
     two flares were observed at 00:56UT on the north west rim of
     Aristarchus. Darling suspects that these effects were due
     to seeing effects and Cameron agrees. However Weier suspects
     that they were TLP? Brightness measurements by Weier were for
     the south west rim of Herodotus 8.0, for a spot at the Cobra's
     Head 9.0 and 7.5 for C.H. Cameron apparently did not see the flashes
     but did suspect that the interior of Aristarchus was a bit unusual. 
     Don Spain did not see anything unsual at all. Cameron 2006 extended

     On 1978 Aug 18 at UT 22:00 Coates (England?, UK, 3" refractor, 
     seeing=II) found that the inner bands of Aristarchus were hard to see, 
     this was odd because the seeing conditions were good and he usually 
     sees them? However he did not believe that there was any obscuration 
     going on. The Cameron 2006 catalog ID=37 and weight=0. The ALPO/BAA

     x120 - no cloud, slight haze, no wind, seeing good) noticed during 
     first part of observing period that Aristarchus was getting steadily 
     brighter, very much brighter than Proclus. This continued until 02:36UT 
     when it dimmed suddenly over a period of about a minute or so. No 
     colour effects seen. ALPO/BAA weight=2.


2023-Nov-28 UT 00:32-01:31 Ill=99% Proclus observed by Brook_C on 2002-3-29

     it Aristarchus that was varying, or Proclus?


2023-Nov-28 UT 00:57-01:53 Ill=99% Eimmart observed by Louderback_D on 1980-4-30

     Louderback, of South Bend, WA, USA observed a bright area over
     Mons Anguis and Eimmart - it resembled a comet and had a bluish 
     colour and varied in brightness. The colour was confirmed as it 
     was not seen in a red filter but could be seen in blue and white 
     light. Other features were checked but did not show anything 
     similar although a violet glare was suspected in the blue filter. A
     sketch was made. Observer made Eimmart 8 in brightness at 07:30UT.
     Noted that the area around Eimmart appeared opaque at times and less so
     at other times. At 08:52UT the phenomenon was seen again. On May 2nd 
     a bright spot was still seen in the region but it was not changing 
     dimensions. During the observation on Apr 30th the atmospheric
     transparency was excellent. A 2.5" refractor was used. Reference:
     Personal communication from Louderback to Cameron on 1980 Jul 16th.
     The Cameron 2006 catalog extension ID of this TLP was 93 and the 
     weight was 4. ALPO/BAA weight=3.

2023-Nov-28 UT 05:18-06:45 Ill=99% Aristarchus observed by Porter on 1978-8-19

     On 1978 Aug 19 at UT02:45-04:00 Porter (Naragansetts, RI, USA, using a 
     6" reflector, Seing = 6/10) noticed blue on the north east corner of 
     Aristarchus and an orange glow on the south east wall. They detected no 
     movement or change in brightness. The observer used both eyes, to make 
     sure it was not an eye defect, and three filters: red Wratten 25, blue 
     Wratten 82 and Violet Wratten 47. Porter found that the colours faded 
     for a duration of 5 minutes and then returned. Their right eye gave a 
     good view and using their left eye they suspected that it was 0.5 steps 
     brighter than the remainder of the crater. The suspected colour 
     remained visible, even under moments of good seeing conditions. The 
     colour eventually faded over time and was eventually gone. Porter 
     reportd seein gcolour here on the following night. Apparently other 
     bright spots showed no colour. Fitton suggests that the filters used 
     confirm that the south east wass was definitely red in colour. The 
     Cameron 2006 catalog ID=37 and the weight=0. ALPO/BAA weight=1.

     On 1978 Apr 23 at UT20:35 (Rawlings, UK, finderscope, x50) 
     observed a bright flash (~0.3 sec duration) near to Copernicus (20W, 
     9N) with rays to the south east whilst he looked through a finder 
     scope. Moore, who studied the drawing, suggests that the area of the 
     flash was near Copernicus. However Cameron says this cannot be the case 
     if the flash was in darkness as mentioned in the BAA Lunar Section 
     circular. She comments that it might have been a meteor? The Cameron

     On 1996 Jul 31 at 22:40UT P. Moore (Selsey, UK, 15" reflector, x300) 
     noticed a lack of detail in the Cape Agarum area - he would normally 
     have expected to have seen some craterlets. However he would not rate 
     this observation much because the seeing was only III and he does not 
     think that it was an obscuration. However just in case he wanted to 
     record this report in the archives. ALPO/BAA weight=1.


2023-Nov-29 UT 07:02-07:38 Ill=96% Alhazen_Alpha observed by Daw on 1972-10-23

     Alphazen Alpha 1972 Oct 23 UT 22:10?-22:13? (Stoke-on-Trent, UK, 
     21cm Newtonian, x217, seeing very good). Flickering colours seen 
     on the north field of Alhazen Alpha mountain. Above UTs 
     estimated by the observer, but the duration of the effect was 3 
     minutes. Colouration centred on the hills that run north to 
     south between Mare Anguis and Mare Crisium. The colour 
     alternated from east to west about 2 or 3 times per second. The 
     colour was not apparent to the north or south, or indeed on any 
     other features. Telescope field of view moved, but effect stayed 
     in the same place on the Moon. Moon't terminator scanned for 15 
     minutes afterwards, but the effect did not recur. The colour 
     seen was mostly red, with a band of orange, and a strip of 
     yellow nearest the hills, the proportions being 6:2:1. The bands 
     seemed to arc up steep above the Moon's surface and flatten out 
     over the mare surface either side of the hill features. No 
     filters were used in the observation. Observer suspects some 
     kind of diffraction spectrum to explain the larger dispersion in 
     the red end of the spectrum. ALPO/BAA weight=3.

     Aristarchus 1968 Dec 07 UT 07:00? observed by Corralitos Observatory 
     (Organ Pass, NM, USA, 24" reflector+Moon Blink) "Bluing around 3 
     craters, strongest at Aris. Lasted several days. Photos show 30% more 
     intensity in blue filter than in red or neutral. Moon's declination 
     northerly. Obs. think it was due to atm. effects" NASA catalog weight=5 
     (very high). NASA catalog ID #1105.


2023-Nov-30 UT 01:04-02:27 Ill=92% Kepler observed by Corralitos on 1968-12-7

     On 1968 Dec 07 at UT 07:00? Corralitos Observatory (Organ Pass, NM, 
     USA, 24" reflector and Moon Blink device) observed a bluing around 
     three craters, one of which was Kepler. This effect lasted several 
     days. Photographs were taken that show30% more intensity in the blue 
     filter than in red or neutral. The Moon's decination was northerly. The 
     observers suspect that it was an atmospheric efect and not a TLP. The 
     Cameron 1978 catalog ID=1105 and the weight=5. The ALPO/BAA weight=3.


2023-Nov-30 UT 02:39-03:14 Ill=92% Aristarchus observed by Pedler_J on 1990-1-13

     On 1990 Jan 13 at UT 22:15-23:05 J. Pedler (Bristol, UK, seeing=III and 
     transparency=excellent, no spurious colour) detected a blue region on 
     the north of Aristarchus, varying in sharpness/diffuseness. The crater 
     rim in this region could not be descerned. Eleswhere the crater rim was 
     normal as too were other features. When a Moon blink device was used, 
     no colour blink was detected, however through the blue filter the 
     suspected area was bright and the crater rim indistinct. Whereas 
     through the red filter the area looked perfectly normal. At 22:30UT the 
     effect had vanished and everywhere was normal. The Cameron 2006 catalog 
     ID=388 and the weight=5. The ALPO/BAA weight=3.

     On 1990 Jan 14 at UT 01:14-01:55 M.C. Cook (Frimley, UK, seeing=poor) 
     observed that Aristarchus did not appear normal for this illumination. 
     the northern half of Aristarchus was "2x>" than the southern half of 
     the crater. There were two white patches of apron material near to the 
     crater Herodotus that were 50% of the brightness of the southern half 
     of Aristarchus. Furthermore the southern half of Aristarchus had a 
     circle - "dull patch on inner S wall with a bright point shining 
     through it. (Bartlett's EWBS?)". The Cameron 2006 catalog ID=389 and

2023-Nov-30 UT 21:56-22:12 Ill=86% Plato observed by Wilkins_HP on 1944-3-12

     On 1944 Mar 12 at UT 23:00 H.P. Wilkins (Kent, UK, 8.5" reflector) 
     observed that Plato appeared incomplete - the central crater had it's 
     north wall obscured. cameron comments that maybe this was due to the 
     low altitude of the Moon? The Cameron 1978 catalog ID=491 and 
     the weight=4. The ALPO/BAA weight=2.

     England, 10" reflector x280, S=VG) "All bright areas were similar in 
     intensity (albedo) but 2 larger ones at times seemed brighter. N & S. 
     The E. IAU? wall of the small craterlet showed most prominently & at 
     times suspected a faint pt. of light just W. of its center. This was 
     very suspect however." NASA catalog weight=1 (very low). NASA catalog
