2020-May-01 UT 03:58-05:54 Ill=53% Curtis observed by Williams_AS on 1882-9-20

     Williams of the UK, on 1892 Sep 20 at Moon's age 8.4 days, noticed a 
     spot that had been seen on the 21st and 23rd of the same year with 
     abnormal brightness. The spot was near Picard. Williams comments the 
     spot was "nearly as large but a little fainter than Picard, This 
     observation was reported in the Astronomical Register of the Royal 
     Astronomical Society and is not included in the Cameron catalogs. It is 
     one of many measurements of the brightness of this spot for different 
     illumination angles and is one of three outlying brightness points 
     spotted on a graph by Willaims. The ALPO/BAA weight=3.

     Mons la Hire 1972 Nov 15 UT 09:45-10:18 M.Geisel (Brisbane, 
     Australia, 12.5" f/8 reflector, x90) discovered the TLP, P. 
     Anderson (9.5" reflector) independently confirmed that the TLP
     had an effect in his Moon Blink device - but the effect 
     (suspected that the blink was caused by the extreme nrightness 
     of the mountain?) was weak and thought it not worth further 
     investigation. Photographs taken by Anderson. Geisel believes 
     the effect to be real and states that the area remained sharp 
     and clear throughout. ALPO/BAA weight=2.


2020-May-02 UT 02:04-02:35 Ill=64% Aristarchus observed by Spencer_S on 1976-6-6

     On 1980 May 23 at UT22:30 (P.W. Foley (Kent, UK, 10" reflector, seeing 
     II) described Aristarchus as a "blue luminous patch", but it was too 
     faint to obtain a CED brightness measurement. Cameron 2006 catalog ID=
     96 and weight=3. ALPO/BAA weight=2.


2020-May-02 UT 02:04-02:35 Ill=64% Tycho observed by Blair_G on 1980-5-23

     On 1980 May 25 at UT 22:18 G. Blair (Bridge of Weir, Scotland, 216mm

     north of Tycho's north wall. Nothing more seen. ALPO/BAA weight=1. 


2020-May-02 UT 02:04-02:36 Ill=64% Copernicus observed by Darling_D on 1990-8-30

     On 1990 Aug 30 at UT02:11-02:36 D. Darling (Sun Praire, WI, USA, 3" 
     refractor, x90, seeing conditions: "at,. boiling") noted a coloured 
     area on the west wall of Copernicus that was unusual in appearance - 
     however other craters along the terminator had a similar effect. There 
     was also a "dazzling bright spot on the E. rim and he witnessed 6 
     flashes from the lighted part of Copernicus over a very short time 
     interval. Cameron comments that the colour may well have been dur to 
     chromatic aberation because a refractor was used. The Cameron 2006 
     catalog ID=408 and the weight=0. The ALPO/BAA weight=1.


2020-May-02 UT 02:04-02:36 Ill=64% Proclus observed by Darling_D on 1990-8-30

     On 1990 Aug 30 at UT 02:11-02:36 D. Darling (Sun Praire, WI, USA, 3" 
     reflector, x90, atmosphereic conditions: boiling) found "N rim of Proc. 
     bright interior uniform gray". The Cameron 2006 catalog report is 
     slight unclear as the description for thnis 1990 Aug 30 TLP also 
     includes Copernicus and Censorinus in the list of TLP craters. So one 
     description which might refere to Copernicus, could possibly have been 
     meant for Proclus, namely: "Dazling bright spot on E rim. Rotated 
     eyepiece but no change. N rim of Proc.......". The Cameron 2006 catalog 
     ID=408 and weight=0. The ALPO/BAA weight=1.


2020-May-02 UT 02:04-02:59 Ill=64% Copernicus observed by Horner_E on 2012-9-24

     2012 Sep 24 UT 22:00-23:00 Copernicus. E. Horner (Salisbury, 
     UK, 15cm reflector) observed a prominent red arc where the 
     sunlit part of the interior wall met the shadow. Sometimes the 
     arc was 1/4 the way around the interior, and sometimes half of 
     the way around. Telescope moved, but the red arc stayed where 
     it was. Eyepieces change, but the effect remained. Other parts 
     of the Moon checked, but no red seen. There were however 
     splashes of green e.g. Longomontanus on the terminator, 
     elsewhere further inland from the termionator, and little 
     splashes of green on Mare Frigoras - but lasting a brief time. 
     The red colour was as strong as a red LED and the green similar 
     to that of the northern lights. The observer's husband was asked 
     to independetly check Copernicus and remarked that he could see 
     a little bit of green at the top and some red near the bottom, 
     along the line of the internal shadow. Although there were 
     checks for red elsewhere on the Moon and none were seen, the 
     Moon was starting to get low and it is typical of spurious 
     colour in a few respects. Therefore the ALPO/BAA weight=1 for 
     safety.


2020-May-02 UT 03:18-04:59 Ill=64% Proclus observed by Classen on 1969-11-18

     Proclus 1969 Nov 18 UT 20:00? Observed by Classen (Pulnitz, 
     Czechoslovakia, 8" refractor) "Brightened, exceeded normal. Brightness

2020-May-02 UT 03:41-07:30 Ill=64% Vitello observed by Unknown_Observer on 1960-8-1 *

     On 1960 Aug? 01 at UT 22:00? an unknown observer detected that Vitello 
     was illuminated -it should have been in shadow? Cameron says that if 
     several days before sunrise then the date could have been July through 
     to December, with August 1st most likely, and ancilary data is 
     therefore given for this date. The Cameron 1978 catalog ID=729 and 
     weight=1. The ALPO/BAA weight=1.

2020-May-03 UT 02:13-04:07 Ill=75% Copernicus observed by Johnstone_GH on 1954-11-6

     Observed by G.H. Johnstone of Albuquerque, NM, USA on 1954 Nov 05 UT 
     20:00 (according to Cameron), but 02:00-04:00 according to the
     original observation and at colongitudes 34.7 to 35.7 deg. 4" 
     reflector, x150 used. The obsewrver reported that the western part 
     (about 1/3rd of the interior) was pitch black with shadow. However 
     there was a zone about as wide, or perhaps only a fourth of the total 
     width that was distinctly a lighter bluish shade, almost like twilight. 
     The shadows of the peaks on the western edge of the rim were clearly 
     seen crossing this bluish shadowed area. Then this area ended sharply, 
     and the farside was bathed in light from the rising sun. The shadows of
     the peak were sharply defined across the twilight zone, and the edge of 
     the pitch black shadow was easily defined but not as sharp as the
     darker shadows crossing the the blue twilight zone. The observer 
     checked other craters but did not see this condition in any of them - 
     they all had the abrupt division between black and white that we would
     normally expect to see. Cameron 1978 catalog ID=579 and weight=2.

2020-May-03 UT 03:06-05:00 Ill=75% Plato observed by Moore_P on 1981-6-12

     P. Moore at 21:10 found the southern wall (and ontothe southern floor)
     of the crater to be indistinct. Elsewhere in the crater everything was
     sharp. The effect was still seen at 21:42UT, but less strong. A check
     was made for colour with aq Moonblink device, but none was seen. There
     was still a trace of this effect at 21:44UT, although detail was now
     becoming visible. By 21:48UT vertical streaks were seen crossing
     the floor from the obscuration area and these were more visible in the 
     red filter and not in the blue. Cameron comments that undefined patches
     on the floor of Plato are not normal. By 21:55UT some craterlets on the
     floor started to become visible and the TLP for Moore ended by UT22:23.
     P.Foley was alerted by Moore and saw a "amssive dense obsecuration
     on the south wall, south floor and south outer glacis to the Mare".
     Foley noted that by 21:50UT the effect was fading and finished by 
     22:03UT. Foley reported an orange translucent haze covering half of the 
     floor, but floor craterlets could be seen on and off - however his 
     atmospheric seeing conditions were IV. At 22:00 UT Foley reported the 
     floor close to the north wall to be "milky or misty". No detail was 
     visible at 21:15UT and variability in the floor continued until 
     23:10UT. Hedly-Robinson was aleted at 21:35UT and found no difference 
     between red and blue views of the area, however he did find that the 
     south rim was indistinct although this effect had lessened by 22:00 UT 
     and was normal by 22:17UT. M. Mobberly saw a white spot on the floor at 
     21:20 UT, whereas he normally would have expected to see craterlets. 
     Mobberly was alerted at 21:40 UT and took some colour photos. He also 
     made sketches that showed variability in the floor and dark lines and 
     patches in the north west corner. However the altitude of the Moon was 
     low. Cameron mentions that two of the photos show loss of detail at the 
     south wall and beyond.and also a change in the floor markings.The north 
     wall at 21:50UT was strangely reddish (didn't think this was spurious 
     colour). The rest of the wall was sharp at 22:20UT through a yellow 
     filter. Large bright patch in the centre and rest of the floor was 
     apparently of the same shading as Mare Imbrium. The above notes are 
     based upon the Cameron 2006 catalog extension TLP ID 145 and weight=4.

2020-May-03 UT 05:26-07:23 Ill=76% Plato observed by Brook_C on 2006-2-8

     C. Brook of Plymouth UK, using a 4" refractor x216, noticed at UT 20:10
     dark patches coming and going (in terms of visibility) on the floor of 
     Plato. Occasional views of the central cratelet (seen as a white spot) 
     were glimpsed. The dark patches seen lasted about 1-2 seconds before
     fading out during each visibility cycle. Teneriff Mountains were 
     checked but no sign of seeing effects that might explain the dark floor
     patches. By 20:26UT the dark patch effect was fading and by 20:31UT 
     floor detail was visible. Observations ceased at UT 20:34. Seeing 
     conditions were II and the Moon was at a high altitude. Other observers 
     were alerted but came on-line after the effect had finished. ALPO/BAA 
     weight=2.


2020-May-03 UT 06:31-08:27 Ill=76% Censorinus observed by North_G on 2007-10-21

     At approximately 18:43UT observer noticed that Censorinus, and 
     its bright apron, appeared particularly brighter than normal. 
     There was some spurious colour present - but just a redness 
     along the southernmost extent of the apron visible; could not
     detect any blue along the northern edge however, he did do not
     suspect the colour to be anomalous. A re-examination at 18:51UT 
     revealed that the crater had faded and was seen to fade visibly 
     in real time to normal levels (over about a minute) by 18:53UT. 
     Other features remained constant and so too did the apparent 
     spurious colour.

     reflector, x159) observed an "anomalous black bar across Aris. Nearly 
     digonal to terminator." The nearby crater Prinz had curious shadow 
     patterns, perhaps related to the rising sun projecting shadows from the 
     eastern rim and "reflected down"? "At 0224 W wall had a break in it & a 
     diffuse glow where it should not be. Manske thinks it was Earthshine 
     effect. At 0305 Weier saw Manske's bar - with diffused light and 
     flicker like an aurora - like a gas with electric charge. At 0325 saw a 
     strange glow in Aris. but may be due to atm. though thought it to be a

     have been due to the seeing? By 21:42 the dark halo was gone. By 21:44-
     21:49 UT the crater was brighter and more normal in brightness than 
     before. By 22:17 UT all was normal. The variations in brightness were 
     also seen by Cook (Mundesley, UK). Observations by Carbognani (Itlay)

     Foley (Kent, UK) saw the west wall dull and stongly coloured. Moore 
     (Sussex, UK) saw the wall as normal. However Cameron points out that 
     Foley (Kent, UK) is a lot more Blue/UV sensitive than Moore. Mosely 
     (Covington, UK) at 22:10 UT noticed a brightening on the East wall and 
     at 01:10-01:25 UT suspected that the interior had a weak yellow-green 
     cast to it. Cook (Frimley, UK) states that orange colour was within the
     interior crater, but green beyond the east rim at the 9 O'Clock and
     the south east corner to floor blue/mauvre beyond the northern rim 
     NW/WSW. Foley sstates that orange and blue/mauvre might be spurious 
     colour, but green one cannot get this way. Cameon suggests chromatic 
     aberatons as a possibility but thinks that the observers concerned were 
     experienced enough to recognize this if it were the cause. Cameron 2006 
     catalog extension ID=239 and weight=0. Moore used a 15?" refletor and

     was a slate blue-gray in colour at 22:45UT. A noticeable green spot
     inside the crater on the south east appeared at 22:25UT and vanished
     at 00:50UT. Cameron notes that one doesn't get green with spurious 
     colour. Crater Extinction brightness measurements were made at 22:00 UT
     (reading=2.8) and at 23:45UT (reading=3.7). The crater dropped in 
     brightness from 3.7 to 2.8 at 23:50UT and remained lower until 3.0 at 
     23:50-03:15 UT. A graph was produced and showed Proclus and Censorinus 
     at similar brightnesses, but Aristarchus variable. The Earthshine was 
     0.3. Cameron 2006 Extension catalog ID=31 and weight=5.

     lights were seen by Pratt, and 28 by Elger, but only 4 by Gledhill, in 
     Brighton. Atmospheric conditions may have made this difference, or the 
     lights may have run up and down a scale from 4 to 28. As to 
     independence of sunlight, Pratt says (Rept. B.A., 1871-88), at to this 
     display, that only the fixed, charted points so shone, and that other 
     parts of the crater were not illuminated, as they would have been to an 
     incidence common throughout.(30) In Pratt's opinion, and, I think, in

     reversal of spurious colour - Cameron suspects that this was a 
     local effect. No spurious colour noticed by anyone else.

2020-May-07 UT 09:27-11:04 Ill=100% Aristarchus observed by Darling_D on 1990-12-2

     F. Graham took some photos of the Cobras Head and found a blue cloud 
     about 50 km in diameter and scattering light - Cameron says that 
     this indicates high density. Darling found the Cobra's Head obscure and 
     variable "clear and bright to diffused". Cameron was alerted observed 
     (02:40UT) variations with periods of approximately 30 seconds, and 
     thought that she could see a red tinge on the east rim of Aristarchus - 
     checks elsewhere found no other colours. Darling found that a blue 
     filter enhanced the effect and a red filter made it disappear. There 
     was a blink at 02:55UT but no blink in the Cobra's Head, which looked 
     fuzzy and lacking in detail. The effect was confirmed by Weier, who 
     also saw two dark spots in the Cobra Head in blue but not in red light. 
     The brightness of the Cobras Head was 6.0, Herodotus floor 5.5, NW wall 
     7.5, South wall, 7.0, Aristarchus south wall 9.0, west wall 9.0, south

     refractor, x28) found Aristarchus to be brighter than he would 
     have expected. Compared to Proclus and Tycho. He observed from 
     20:55-22:38 and found it to be normal in brightness over this 
     time. The ALPO/BAA weight=1.


2020-May-08 UT 04:57-06:53 Ill=99% Picard observed by Ingall on 1865-9-5

     Conspicuous bright spot seen on 6th. Also seen on 7th, absent on 8th.
     Cloud-like effect where light had been (on 8th). Cameron 1978 catalog

2020-May-08 UT 06:52-08:32 Ill=99% Aristarchus observed by Mellor on 1978-5-22

     Aristarchus was not normal, but all the following features were: Mare 
     Crisium, Proclus, Sinus Iridium, Grimaldi, and Tycho. Observed by 
     Mellor and Fitton, UK. Observer notes that Aristarchus is brighter than 
     Tycho when normal. Estimated variation was 25%. However the Moon was 
     low and the Moon was yellow. Despite this the observer decided that the 
     effect was real. Cameron 2006 extension catalog ID=32 and weight=2. 
     ALPO/BAA weight=1.


2020-May-08 UT 07:33-08:14 Ill=99% Aristarchus observed by Moore_P on 1977-7-1

     P Moore, Selsey, Sussex, UK, used a 5" x250 scope and between
     23:50UT on Jul 1st 1977 and 00:10UT on Jul 2nd 1977 observed
     Aristarchus. The south wall of the crater was reddish, extending 
     down to the outer south east wall (IAU). However seeing was no 
     better than III-IV and he was 99% sure that the colour was 
     spurious. His report was submitted only in case any other 
     observers reported something similar. ALPO/BAA weight=1.

2020-May-08 UT 10:35-11:41 Ill=99% Torricelli_B observed by Mobberley_M on 1985-12-27

     Mobberley noticed that Torricelli B was bright and had an even brighter 
     spot on the inner north wall. The observation was made from UT19:45-
     21:40 using visual and video techniques. There was also a bright region 
     NNE of Toricelli B, that was noticed. Foley examined the video and 
     found that the crater faded in brightness over time and also the bright 
     area to the NNE was not as bright on video as had been seen visually. 
     Foley speculates that because the CCD camera was sesnitive to the near 
     IR that maybe the spot was blue?. Foley observed from 21:12-21:21UT and 
     also saw the bright spot on the inner north wall - but saw a blue halo 
     around the crater. Response in blue filter, darkening over whole 
     region. Brightness measures with a crater extinction device (CED) 
     indicated that the crater was 80-85% the brightness of Censorinus. 
     There was a bright area NNE of the region. M. Cook observed 22:10-
     22:16UT (15cm reflector and seeing III-IV) and also saw that the crater 
     was very bright indeed with a spot NNE of the region (same position as 
     28/28 1985 observation) - suspected that the crater might have been 
     brighter than Censorinus, but judgement effected by seeing. In a blue 
     filter the crater dulled leaving the bright spot prominent (but only 
     during a good moment of seeing) - therefore had some suspicion of 
     seeing effects. At 01:00-01:04UT M. Cook used a 12" reflector on the 
     area, but the seeing was even worse - but did manage a check of the 
     brightness of Torricelli B to Censorinus and now made it one quarter of 
     that of Censorinus and no sign of the crater dimming in the blue as had 
     been seen earlier in the 6" refletor. A. Cook (Frimley, seeing V) at 
     21:15UT (Dec 27) thought that Torricelli B looked normal and saw no 
     colour. At Dec 28 at UT 00:02-00:25 A. Cook obtained some CCD images 
     through red+IR (Wratten 25) and IR (Wratten 87) but found no colour 
     differences, though there was a very slight hint that a brightness fade 
     may have occurred between those two observing times. Note that this
     report does not have an entry in the Cameron 2006 Extension Catalog.
     The ALPO/BAA weight=4.

     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.

     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

     boundary, and red on the NE-SE floor:wall boundary. Atmospheric 
     spectral dispersion existed in many regions, but did not change 
     like the colours in Plato. Similar appearance craters such as

     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.

     Heywood of Westville, Ohio, USA, using a 2" refractor under fair seeing 
     conditions, saw an unusually bright glow covering the dark part, nearly 
     uniform. Thought it was electric because it was too bright for

     "green glow in the "peninsular region" of Cape La Place (south of poss. 
     Helicon A?) and brown on the Earthlit limb. Foley (Kent, UK, 12" 
     reflector) noticed a "pin point glow surrounded by blue-green halo" 
     through a blue filter, but not seen through a red filter. He also 
     suspected some brightness variations. He noted that Aristarchus was 
     barely seen and Copernicus was only a faint smudge, presumably because 
     of the bright limb? J. Cook (Frimley, UK) observed a white glow in the 
     Cape region (made up of pin points?) - no other places had a similar 
     effect. P. Moore (Selsey, UK, 12" reflector) reported that nothing 
     unsual was to be seen anywhere on the Moon. M. Cook (Frimley, UK) found 
     a "bright point source near the tip of LaPlace perhaps maupertius D (or 
     LaPlace D?)." This was seen in a blue filter but not through a red 
     filter - the limb was also seen as bright and the cape as a faint 
     patch. Holmes (Lancashire, UK, 30"? reflector or refractor?) although 
     commenting that Aristarchus was a bit dull, could not see the Sinus 
     Iridum glow, North (UK) could only detect the vague presence of 
     Earthshine throug his finder scope, but not in his telecope. The

     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.

     weight=2.


2020-May-27 UT 04:21-04:27 Ill=19% Mare_Nubium observed by Cook_AC on 1986-3-15

     On 1986 Mar 15 UT 19:51-19:55 A. Cook (Frimley, UK, Naked Eye 
     and 12" reflector, x60, seeing IV, transparancy poor) 
     observed a naked eye flash at 19:50.5 UT in the Mare Nubium 
     area. The flash was white in colour and lasted not longer 
     than 0.5 sec and was about magnitude 2 at most in brightness. 
     There was no rise or fade associated with this flash. Upon 
     checking the area with the telescope, the observer reproted 
     seeing a faint fuzzy small patch that came and went over 
     several seconds in the same general area - but this may have 
     been due to the seeing conditions and/or glare from the 
     bright side of the Moon. The patch area was about the same 
     size as Aristarchus, i.e. approx 40 km across. Note however 
     that observing conditons were too poor that night to see 
     Aristarchus. At later observing sessions from  20:30UT 
     onwards, the patch was not seen. The ALPO/BAA weight=3.

     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. 


2020-May-28 UT 02:21-03:48 Ill=28% 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.


2020-May-28 UT 02:22-04:04 Ill=28% Proclus observed by Cook_MC on 1985-4-25

     Almost certainly the following was spurious colour and not
     a TLP. Proclus was found to be brighter than Censorinus. 
     Red was seen on the northern inner floor and blue on the
     edge of the external north rim NNE-NW. The rim to the SW
     could not be seen. ALPO/BAA weight=1.


2020-May-28 UT 02:54-04:01 Ill=28% 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

     G Johnson of Swanton, MD, USA used a 2" refractor at f/12.
     Aristachus revealed as a red spot on a photo of the Moon. This
     was similar to another photo obtained on 1988 Apr 21st. Frame (with 3
     exposures present)reveals a dim star like point near Campanus on 
     exposure 1. Expsoure 2 shows it a little east on the Earth-lit 
     part. Exposure 3 shows it off the south-east limb. Apparently 20
     minutes later took 2 exposures and frame 18 was a double. The
     second exposure revealed an object farther from the limb but the
     first exposure does not show the object. The two high power exposures 
     do not show it. Cameron could not see the spots that Johson describes
     on his slides, but did see several spots (defects?) on the 
     8 and 12 second exposures near Hevelius and also on the 20 second
     exposure near to Hecataeus only. BAA members observed star like 
     flashes a few hours earlier - near Aristarchus. One BAA member, Madej, 
     had seen a green glow in Arisarchus in two places in two eyepieces.

2020-May-28 UT 04:32-05:16 Ill=28% Hecataeus observed by Johnson_G on 1985-4-26

     G Johnson of Swanton, MD, USA used a 2" refractor at f/12.
     Aristachus revealed as a red spot on a photo of the Moon. This
     was similar to another photo obtained on 1988 Apr 21st. Frame (with 3
     exposures present)reveals a dim star like point near Campanus on 
     exposure 1. Expsoure 2 shows it a little east on the Earth-lit 
     part. Exposure 3 shows it off the south-east limb. Apparently 20
     minutes later took 2 exposures and frame 18 was a double. The
     second exposure revealed an object farther from the limb but the
     first exposure does not show the object. The two high power exposures 
     do not show it. Cameron could not see the spots that Johson describes
     on his slides, but did see several spots (defects?) on the 
     8 and 12 second exposures near Hevelius and also on the 20 second
     exposure near to Hecataeus only. BAA members observed star like 
     flashes a few hours earlier - near Aristarchus. One BAA member, Madej, 
     had seen a green glow in Arisarchus in two places in two eyepieces.

2020-May-30 UT 02:29-04:10 Ill=50% Aristarchus observed by Mobberley_M on 1985-4-27

     Mobberley and Foley note that Aristarchus was very
     prominent in Earhshine. Little other detail seen
     in Earthshine other than the limb. The Cameron
     2006 extension catalog then says: "Confirm moving 
     side to side. Saw bright blue spot in center" however 
     it is unclear whether this refers to Aristarchus,
     or Torricelli-B - the latter was also undergoing a TLP
     at this time. Cameron 2006 extension catalog ID=267
     and weight=5 (confirmed?).

     On 1985 Apr 27 UT 22:00 M. Mobberley (Suffolk, UK) could not see much 
     detail in Earthshine (apart from Aristarchus), except that there was a 
     brightness on the western limb of the Moon. The Cameron 2006 catalog

     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 
     fades for single stars. The Cameron 1978 catalog ID=1384 and weight=4.

     (Frimley, Surrey, UK, 12" reflector x240, S=IV (Antoniadi)) 
     "Small triangular area on the NW floor of the crater, at the 
     foot of the rim, was slightly brighter in blue light than in red 
     (Moonblink used). Suspected this was due to the poor observing 
     conditions. Certainly blink reaction was not unmistakable".

2020-May-31 UT 02:55-04:51 Ill=61% 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
     weight=3.
