On 1987 May 03 at UT 19:00-19:30 H. Miles (Cornwall, UK, 5" refractor, x30) found the Earthshine to be both pink and bright with prominent features clearly visible. A "brilliant" star-like point was seen in Aristarchus crater. There was another, albeit less bright spot near Darney-Agatharides. Spots pesisted despite various tests. Foley also confirmed that the Moon looked pink to him as well. The Cameron 2006 catalog ID=298 and weight=1. The ALPO/BAA weight=1.
On 1987 May 03 at UT 19:00-19:30 H. Miles (Cornwall, UK, 5" refractor, x30) found the Earthshine to be both pink and bright with prominent features clearly visible. A bright spot was seen near Darney- Agatharides. An even more "brilliant" star-like point was seen in Aristarchus crater. Spots pesisted despite various tests. Foley also confirmed that the Moon looked pink to him as well. The Cameron 2006 catalog ID=298 and weight=1. The ALPO/BAA weight=1.
On 1983 May 15 at UT20:30-21:05 P.W. Foley (Kent, UK, 12" reflector) was unable to see Aristarchus in Earthshine, though other craters were clearly visible. However by 21:30 the Cooks could clearly see Aristarchus. The Cameron 2006 catalog ID=215 and the weight=0. The ALPO/BAA weight=2.
W.limb 1983 May 15 UT 20:30-21:00 R.Moseley (Coventry,UK, 6" reflector, x60) observed a faint but extensive brightening of the W.limb, perhaps a little stronger at PA=80-90 deg. No other features seen in Earthshine. Observation confirmed br R.Martiott (Northampton, UK, 8.5" reflector). ALPO/BAA weight=1.
1837 Mar10 UT 13:46 (19:07 local time) T.G. Taylor (Madras, India) whilst observing a 9th magnitude star being occulted, noticed a 6th magnitude nebulous spot where Aristarchus should be. Had never seen anything quite as bright as this on previous occasions. ALPO/BAA weight=2.
On 1991 Dec 09 at UT 22:50 D. Darling (Sun Praire, WI, USA, 3" refractor, x36) witnessed a flash in Grimaldi crater. Cameron comments that others had seen a flash there earlier, and there was a meteor swarm. Fritschel (madison, WI, USA, naked eye observing) detected 3 flashes in Grimaldi and also at the western limb of the Moon. D. Weier (Sun Praire, WI, USA, 3" refractor, x36) was also observing. The Cameron 2006 catalog ID=436 and the weight=5. The ALPO/BAA weight=2.
On 1983 May 15 at UT21:30-22:30 M.C. Cook and J.D. Cook (Frimley, UK) could clearly see Aristarchus in Earthshine, whereas earlier that night P.W. Foley (Kent, UK) could not see the crater although other features were cisible. The Cameron 2006 catalog ID=215 and the weight=2. The ALPO/BAA weight=1.
Macrobius 1938 Jun 02 UTC 18:00? Observed by McLeod (England? 5" ? reflector) "Changes in dark areas. (near Proclus where Green saw phenomenom. see #443)" NASA catalog weight=2 (low). NASA catalog ID # 444.
On 1966 Apr 24 at 21:30UT R.Livsey (Scotland, 6" reflector at x275) observed that Aristarchus was "fluorescent" in Earthshine. It is uncertain whether the description of "fluorescent" should be involve this observation being categorized as a TLP, however just for safety it will be assigned an ALPO/BAA weight=1. This was a BAA Lunar Section report.
On 2003 May 05 at UT 19:50 P.G. Salimbeni (Italy) saw a faint flash (possible optical illusion) near to Pallas in Earthshine. The ALPO/BAA weight=1.
On 1987 Mar 04 at UT 19:03-19:47 H. Miles (Cornwall, UK, 5" refractor, x30, S=clear) found at 19:03 that Aristarchus was exceptionally bright (even without blocking out the sunlit side of the Moon), being the most easily seen crater on the Moon, and this was despite the sky not yet being dark. The crater had faded by 19:20UT and at 19:47UT Earthshine was no longer visible. CED brightness measurements were made and were less than usual and the inside of the crater may have had a blue/gray colour (unclear from the Cameron 2006 catalog description). The Cameron 2006 catalog ID=299 and the weight=2. The ALPO/BAA weight=2.
On 1983 May 16 at UT20:35-22:10 P.W. Foley (Kent, UK) noted that Aristarchus was dull in Earthshine (UT21:36-21:40). The floor was a luminous rose/violet colour. The Cameron 2006 catalog ID=219 and the weight=0. The ALPO/BAA weight=1.
On 1880 Nov 06 at UT 20:00 an unknown observer observed a TLP at an unknown location on the Moon. The Cameron catalog has an entry for this date and time but does not specify the location, the observer or what was seen. The Cameron 1978 catalog ID=218 and the weight=0. The ALPO/BAA weight=1.
W.limb 1983 May 16 UT 22:00-23:00 R.Moseley (Coventry,UK, 6" reflector, x60) observed a faint but extensive brightening of the W.limb, perhaps a little stronger at PA=80-90 deg. No other features seen in Earthshine although Aristarchus suspected. ALPO/BAA weight=1.
1837Mar11 UT 15:27 (20:48 local time) T.G. Taylor (Madras, India) whilst observing a star being occulted, noticed a 6th magnitude nebulous spot where Aristarchus should be. Had never seen anything quite as bright as this on previous occasions (except the day before). ALPO/BAA weight=2.
On 1983 May 17 at UT20:13-20:40 P. Madej (Huddersfield, UK, x38 and x63) found that Aristarchus was normal in appearance, but at 20:19 a blood red disk was seen as bright as a 6th magnitude star. The colour did not vary but the brightness changed from 4 to 8 over a 1.5-3min period, on the south west wall. Foley (Kent, UK, 12" reflector)observed Aristarchus at 22:10 and noted that it had the same rose-violet colour as had been seen by him a day earlier. The Cameron 2006 catalog ID=220 and the weight=0. The ALPO/BAA weight=3.
On 1984 Nov 28 at UT 17:30-18:05 P. Madej (Huddersfield, UK) found that the crater Hubble had a cream white oval patch for short while that was 2x brighter than it's surroundsings. The Cameron 2006 catalog ID=254 and weight=3. The ALPO/BAA weight=2.
Daniell 1979 Apr 02 UT 21:45-22:14 Obseved by Madej (Huddersfield, UK, 158mm reflector, f/4.2, x36-110, seeing II-III) "Obscuration seen" BAA Lunar Section Report. Cameron says that this was a bright white cloud that covered three quarters of the crater. A yellow filter was used at 21:48, but the cloud was still white, albeit thinner (at x110). By 22:14UT the TLP was barely visible and again no colour seen. Buczynski (Lancaster, UK, seeing = poor) saw spurious colour. Later (22:31- 22:46UT?) Mellor obtained some photos, but these revealed no colour. The Cameron 1978 catalog ID=48 and the weight=3. The ALPO/BAA weight=2.
On 1983 May 17 Foley (Kent, UK, 12" reflector)observed Aristarchus at 22:10 and noted that it had the same rose-violet colour as had been seen by him a day earlier. The Cameron 2006 catalog ID=220 and the weight=0. The ALPO/BAA weight=2.
On 1983 Jan 19 at UT 18:00-19:00 G. Amery (Reading, UK) discovered that Aristarchus could not be seen in Earthshine, this was odd because less prominent features could be seen. Other observers (Moore and Foley) confirmed the very low brightness of the crater. The Cameron 2006 catalog ID=197 and the weight=2. The ALPO/BAA weight=2.
On 1983 Jan 19 at UT 18:00-19:00 G.W. Amery (Reading, UK) found that Messier was difficult to define. The Cameron 2006 catalog ID=197 and the weight=2. The ALPO/BAA weight=1.
Theophilus 1955 Jun 25 UTC 20:30 Observed by Firsoff (Somerset, UK, 6.5" reflector, x240) "Blue mist. Both c.p. & ENE (IAU?) ridge appear misty, slightly blueish & milky -- renders effect perfectly. Absent next nite". NASA catalog weight= 4 (high). NASA catalog ID #596.
On 1981 Feb 10 at UT21:46-21:49 P. Madej (Huddersfield, UK) found a 2nd mag star-like point on the north east wall of Aristarchus crater. M. Price (Camberley, UK) at 21:46 and 21:49. North (UK) detected flashes from the central peak. Foley saw Aristarchus as a "translucent glow". Moore, Pedler and Ratcliff could not find Aristarchus. Earlier though Amery (Reading, UK) had found Aristarchus to be sharply defined. Cameron 2006 catalog ID=122 and weight=5. ALPO/BAA weight=3.
On 25 Jun 1993 at UT 23:30-23:52 Carlos Colesanti (Mairinque, Brazil) obtained two CCD images of Julius Caesar crater and noticed a brilliant fuzzy area on the rim of the crater. This appeared in both images and resembled a fuzzy white blob. Note that this is a REA-Brazil observation. ALPO/BAA weight=1. Cameron (2006) ID=463.
Near Ross D (23E, 12N) 1964 May 18 UT 03:54-04:53 Observed by Harris, Cross et al. (Whittler, CA, USA, 19" relector x720, 8" reflector x322, S=G) "White gas obscuration. Moved 20mph, decreased in extent. Phenom. repeated. Drawing." NASA catalog weight=5. NASA catalog ID 811. ALPO/BAA weight=4.
White spot near Censorinus 1966 Dec 18 UT 23:40-23:46 Observed by Enie (Pittsburgh, Pennsylvania, USA, 8" reflector x100, S=G) "Attention drawn to pink color in this usually white patch.

Linne 1867 Aug 06 UT 21:00? Observed by Buckingham (England?) "Crater in darkness, he saw a "rising oval spot". Other obs. saw it as a triang. Bold black spot pointing to earth, slowly diffused white & drift of white on slope of pyramid. (indep. confirmation?)" NASA catalog weight=5 and catalog ID #155. ALPO/BAA weight=2.
On 2000 Feb 11 at UT19:00 G. North (Norfolk, UK) telephoned TLP coordinator, Patrick Moore, to report a possible colour anomaly in Aristarchus. Moore had poor conditions in Selsey (UK) and saw nothing unusual. However by this time North was reporting that, the colour was fading. Two other BAA members were alerted, but were clouded out. The ALPO/BAA weight=3.
1968 Apr 04 UT 18:45-19:20 Observed by Darnella (Copenhagen, Denmark, 6" refractor, x183) "Small area just E(ast.) of Menelaus was seen with a reddish color which gradually faded.

Aristarchus appeared to glow in Earthshine with a faint green luminescence that moved from side to side. A bright blue central spot was also seen. The green colour was detected in two seperate eyepieces. Observation made from England. Cameron 2006 catalog extension ID=266 and weight=2. ALPO/BAA weight=2.
On 1888 Jul 16 at UT 05:35? Holden, at Lick observatory, CA, USA saw a "Lunar Volcano, 1st magnitude star on the dark side. Yellow light tinged with red from refractor's secondary spectrum (facet glint? or peak catching sun before others? Hunt saw similar phenomenon in 1863." Corliss states that it was later revealed to be a mountain ridge near the southern termination of the Alpes. Cameron 1978 catalog ID=357 and weight=1. ALPO/BAA weight=1.
Mons Piton 1843 Jul 04 UT 21:15-22:00 Observed by Gerling (Germany?) "Bright pt. glowing like a star on the S. extension of the Alps. On the following eve. found a small mt. which he did not see before." NASA catalog weight=1. NASA catalog ID=122. ALPO/BAA weight=1.
Ptolemaeus 2020 Feb 01 UT 19:40-19:50 P. Sheperdson (York, UK, 102mm Mak - BAA) saw an "ashen" sliver of bright light across the floor. Images taken. This maybe normal appearance - though observer re-observed in May and found the effect different in that there was no "ashen" like effect. Visual sketches and time lapse image sequences welcome. If doing visual work - try using a polaroid filter and rotate it to see if that makes any difference. For imaging work, please over-expose slightly to bring out detail on the floor; you could also try colour imaging of the floor as an interesting experiment - though for comparison purposes image other terminator features exhibiting shadow spires. ALPO/BAA weight=1.
Proclus 1972 Jan 23 UT 15:20-16:50 observed by Stolzen (51.17N, 9.25E, 50mm refractor, T=2, S=2) "Pure bright white point within crater" - Hilbrecht and Kuveler, Earth, Moon & Planets, 30 (1984), p53-61
On 1983 May 20 at UT00:00-03:00 K. Marshall (Medellin, Columbia) noted that Mons Piton was too bright near the terminator and was surrounded by shadow. A sketch was made. The mountain appeared segmented with one thin shadow line. The mountain looked like a Mexican Sombrero hat. This appearance is normal. What was abnormal was that Piton was brighter than Proclus, and only slightly fainter than Censorinus. The CED brightness measurements were normal Piton=3.6, Proclus=3.5 and Censorinus= 3.7. Please check to see whether this is still the case. The cameron 2006 catalog ID=221 and the weight=3. The ALPO/BAA weight=1.

At 03:00UT(?) Evrard et al from the western US(?) saw somewhere a reddish glow, followed by black obscuration. The date in the Middlehurst catalog is 18/1/65, but there may have been a descrepency between local time date and UT date? Cameron 1978 catalog TLP No=916 and weight=3.
On 1984 Dec 01 at UT 20:00 a British Astronomical Association Lunar Section member (Southam, Warwickshire, UK) found no detail on the floor of Autolycus, despite there being plenty of detail on the floor of Aristillus crater. According to Foley, there should be some detail at this stage of illumination. Grego reports that the observation was from a Society for Popular Astronomy member and they described "a homogeneous grey veil over the 20 km floor of the crater". The Cameron 2006 catalog ID=255 and the weight=2. ALPO/BAA weight=2.
On 1982 Jun 30 at UT 02:05-02:15 Marco Petek (Porto Alegre, Brazil) found that the region between Eratosthenes and Bode (7W, 13N) looked like it had a darkening (cloud?) that had even darker points inside. The Cameron 2006 catalog ID=172 and weight=3. The ALPO/BAA weight=2.

Tycho 2003 May 10 UTC 03:15 Observer Robert Spellman (Los Angeles, USA) - "CCD video of spur-like features coming off N & S edges of central peak - spurs pointed eastwards". It is now thought that this effect is almost certainly seeing flare as it is visible on other features in the image, although to a much lesser extent. The ALPO/BAA weight=1.
On 2001 Jun 29 at UT22:16-22:22 C. Brook (Plymouth, UK, 60mm refractor, x120, no spurious colour seen, seeing I) observed that the central peaks of Alphonsus looked bright at 22:16UT but had dimmed by 22:22UT. The three dark patches on the floor of Alphonsus were clearly seen. The ALPO/BAA weight=1.
On 2001 Jun 29 at UT 22:16-22:20 C. Brook (Plymouth, UK, seeing conditions very good, x120) reported that the central peak of Alphonsus was brighter than the central peak of Arzachel (or was it the other way around?). Cook observed 4 hours later from Washington DC, USA and found that on CCD images that the central peak of Alphonsus was only slightly less than that of Arzachel. The ALPO/BAA weight=2.
Plato 1979 Apr 06 UT 18:00-21:00 Observed by Crick (Belgium, seeing II- III) Part of floor darker than normal and obscuration on inner west wall - the effect did not change during the observation. Drawing made. Cameron 2006 catalog ID=49 and weight=3. ALPO-BAA weight=2.

(albedos disagree at same phases, so are real anomalies). (normal here?)." NASA catalog weight=4 (high). NASA catalog ID #461.
On 1987 Mar 09 at UT20:00 M. Mobberley (Sussex, UK) obtained some video of Mons Pico - apparently these show the mountain with a puzzling appearance (not sure whether it was the observer who claimed this or some one who analyzed the tape). The Cameron 2006 catalog ID=300 and the weight=5. ALPO/BAA=1.
1864 May 15-16 UT 23:00-01:00? East of Picard (probably Curtis Observed by Ingall (Camberwell, England?) "Remarkable bright spot" NASA catalog weight=3 (average). NASA catalog ID #134. ALPO/BAA weight=3.

Neighbouring craters/detail were sharp. Details in the crater wall interior were starting to become visible as time went on, but it had clouded over by 11:30. A Moon Blink was used but no colour was detected. ALPO/BAA weight=1.
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.

At 21:41 it clouded over but at 21:47-21:48 it cleared briefly and effect was noted again. Also Darney appeared very visible through the red filter. Probably spurious colour as the Moon was -18 deg in declination and the whole Moon had a slight brownish tinge" ALPO/BAA weight=1.
Darney observed by Cook (Frimley, UK, seeing III, Moonblink device) See TLP report for Bullialdus (eastern side) concerning reddish areas. At 21:41 it clouded over but at 21:47-21:48 it cleared briefly and the effect was noted on Bulialdus again. Also Darney appeared very visible through the red filter. Probably both effects were spurious colour related as the Moon was -18 deg in declination and the whole Moon had a slight brownish tinge. An ALPO/BAA weight of 1 is assigned to this TLP."

On 1980 Jul 24 at UT02:00 F. Graham (East Pittsburgh, PA, USA, 6" reflector) took some photos (albeit out of focus) that showed a bright spot on the west rim. Cameron comments that this spot was sharp compared to the rest of the photograph, so was probably a photographic artifact. The effect was not seen in the finder scope. The Cameron 2006 catalog ID=103 and weight=2. The ALPO/BAA weight=1.
Aristarchus 1966 May 01 UT 21:55-22:45 Observed by Paterson, Brown, Sartory, Ringsdore (England, 12" reflector x252 for the former and 8.5"? reflector for the latter) "Eng. moon blink system detected red spots with vis. by all but Ringsdore.

At 02:00 he observed pink on the south west wall of Aristarchus crater. At 01:24UT the Aristarchus ray was yellowish, however the entire Moon had a grey-yellow tinge of colour. Chromatic aberation was observed at 01:56UT. By comparison Gassendi was checked and had no colour. At 02:10 the crater wall of Aristarchus was unusual and was quite different in appearance to rims of other craters. The cameron 2006 catalog ID=375 and the weight=1. The ALPO/BAA weight=1.

Deslandre - 1965 May 12 at UT 19:10 E. Penzel (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% sure that what he detected was impact debris/cloud?. The ALPO/BAA weight=1.
Gassendi 1968 Oct 03/04 UT 19:30-19:50 & 00:20-01:40 Observed by Rawlings (Aylesbury, UK, 6" reflector low magnification) and by Moore (Selsey, Sussex, UK, 12.5" reflector, x360) "Slight blink (Eng.) arcuate in shape, N. of c.p.

On 1988 Sep 23 at 19:40-19:55 & 20:36-20:41 G. North (760mm Coude Rrefractor, x250, Royal Grenwwich Observatory, Herstmonceux, UK, seeing V, Transparency: Fair). 19:40-19:55 image very unsteady. All seems normal in other crtaters with the exception of Arcimedes. Much of the rim seems indistinct apart from a 1/4 length of the west rim. Strongly suspected that this was due to a combination of seeing and illumination. UT 20:02-20:06 - checked the area with a lower magnification 10" Astrographic Refractor - the crater seems more normal, so suggesting that the theory was correct. 20:36-20:41 returned to the 30" reflector, and the crater appeared similar to the start of the session. This is almost certainly not a TLP, but it would be helpful to have some images or sketches to check this theory out. Weight=1.
On 1985 May 02 at UT 20:20-20:38 J.D. Cook (Frimley, UK) noted at 20:20 found the south rim (and just outside) to be blurred in appearence and there was also a hazy shadow inside the crater. M.C. Cook found a "break in clarity in break on S wall". Miles (UK) also found the south wall blurred in appearance and Foley (Kent, UK) noted that the area was featureless and the 2 craters positions at 1 o'clock high up on the inner wall were obscured", although just north of these was sharp detail. Foley also recorded that the shadow on the east wall was opaque"and that thye inside of Aristarchus was slate/blue in colour and dull, however by 20:28 the crater had brightened by 0.4 steps on Foley's CED device and the missing craterlets were visible again. Jean (Canada, 4" refractor) observed a rose colour intermittently (UT 1948- 20:58) - however Cameron suspects that this is chromatic aberation. The Cameron 2006 catalog ID=269 and the weight=5. The ALPO/BAA weight=3.
On 1987 Mar 13 at UT02:00-03:00 De Groof (Belgium, 8" reflector x150, seeing=clear) noted that the north west part of Aristarchus had a blood red shimmering filling the whole crater. A video by Mobberley some 18 hours later, shows variation in Aristarchus. Cameron 2006 catalog ID= 301 and weight=5. ALPO/BAA weight=3.
On 1983 Dec 17 at UT 17:25-19:20 Moseley (Covington, England, UK, x120 and x240, seeing=III and spurious colour present) found that the inside of Aristarchus crater was dull and slightly blue. Suspected the colour to be spurious: at 19:20 at x240 the colour was pink but at x120 there was no colour. Cameron 2006 catalof ID=234 and weight=3. ALPO/BAA weight=2.
Alphonsus 1966 May 03 UTC 21:30 Observed by Smith (England, 10" reflector) and Corralitos Observatory (Organ Pass, NM, USA, 24" reflector, Moonblink) "Reddish patches.

On 1982 Jan 09 at UT18:46-21:42 Henderson, Sykes and Radley saw an obscuration near Le Verrier - a completely circular halo with dark mare showing through it for a duration of 15 minutes. This was during a total eclipse of the Moon. Cameron 2006 catalog ID=162 and weight=5. ALPO/BAA weight=3.
On 1982 Jan 09 at UT21:37 P. Moore (Selsey, UK) observed that Plato underwent brightness and colour changes, during a total lunar eclipse. At 20:07UT Madej observed a "slight anomaly in Plato". Cameron 2006 catalog ID=162 and weight=5. ALPO/BAA weight=3.
On 1982 Jan 09 at UT 18:46-21:42 M.Mobberley (UK) observed that Schmidt was very bright compared to its surroundings during a total lunar eclipse. Cameron 2006 catalog ID=162 and weight=5. ALPO/BAA weight=2.

On 1984 Dec 07 at UT 19:30-23:30 M. Mobberley (St Edmunds, UK, seeing=IV-V, transparency=good, spurious colour seen) found 2 bright pathces on the east rim on alternate sides of a bright region. The band from the central 16km wide region was dark on the east side. Foley (Kent, UK, 12"reflector, seeing=II-III) found Aristarchus to be not as bright as normal, apart from the band that Mobberley found (1 hour later). The dark regions were a murky green colour (bright through green, blue and yellow filters and dark through red and orange filters). Cook (Frimley, UK, transparency=excellent, CCD camera used) found a bright "bulge"on the eastern side. Apparently data suggests that the band was brighter in red than in near IR light. Cook's calibrated brightness measurements suggest that there was no change in brightness over the crater with time. Two other bright points were seen: one at the Cobra's Head and another half way between the east rim of Aristarchus and passes Herodotus. Wratten 29 (deep red), Wratten 87 (near IR) and combined Wratten 29 and Wratten 87 were used. In the red Wratten 29 filter the brightness falls at22:20 at Shroters valley and then rises in the bright ray. They return to normal at 22:30UT. There was however a lot of measurement noise from the brightness readings of points B and D. The Cameron 2006 catalog ID=256 and the weight=5. The ALPO/BAA weight=3.
On 1963 Dec 30 at UT11:00 many observers reported seeing a red glow on the North East (IAU?) limb of the Moon. This was also captured on a photograph. Cameron suggests eclipse geometry as an explanation. Thye Cameron 1978 catalog ID=792 and weight=1. The ALPO/BAA weight=1.
On 1953 Jan 29/30 UT 23:00?, 01:00? Dubois (Floirae, France) observed excess luminescence, in Mare Fecunditatis, between 420nm and 470nm (maximum at 435nm) and between 480nm and 520nm (maximum near 505nm). 20-60% during eclipse at 50' from the centre of the umbra, during a lunar eclipse. The cameron 1978 catalog ID=557 and weight=5. The ALPO/BAA weight=4.
On 2000 Jan 21 UT04:40 G. Emersen (Golden, CO, USA, 30cm focal length lens with Wratten 25 ref filter) took 43 CCD images of the eclipse of the Moon and on one of them at 04:40UT (exposure 0.3 sec) a relatively bright spot appeared in the southern part of Mare Fecunditatis. The spot looks sharper than the rest of the Moon and so might be a cosmic ray? CCD images taken from Washington D.C. by A.C. Cook at this time, do not show this spot, however exposures were at intervals of 0.25 sec and so might have missed this spot if it happened during image readout. The ALPO/BAA weight=1.
On 1953 Jan 29-30 UT 23:05-01:40 G. Brown (UK?) observed a white patch of light of low brightness was seen to move around the north polar area. Coloured bands were also seen on the Moon.
On 1877 Feb 27 at UT19:19 Prof. Dorna (Turin, Italy) observed a flickering light on the lunar surface during a lunar eclipse. The Cameron 1978 catalog ID=186 and the weight=2. The ALPO/BAA weight=2.
On 1848 at UT 21:00 Rankin and Chevallier (France?): Luminous pts. seen during an eclipse. Cameron ays that year 1847 given by Middlehurst must be wrong as age is 2.7 days for this date in 1847 and could not be 18- 19 as in Middlehurst because eclipse is on the 19th at 21h (mid) in 1948. aux. data here are for 1848. At 21:12 Forster (England) and Bruges (France) observed rapid changes in red colour. The Cameron 1978 catalog ID=126 and 127 and the weight=5. The ALPO/BAA weight=3.

It was comparable to the illuminated rim of Proclus in brightness. No colour seen. The spot was not visible the next night. The ALPO/BAA weight=1.
On 1895 Mar 10 L. Swift et. al (Lowell Observatory, Flagstaff, AZ, USA) and Elger et al. (England), observed during a total lunar eclipse that Aristarchus was glowing with brilliance never seen before. This attracted everyones attantion.
