In 1821 Feb 05 at UT18:00? Garding (Breman, Germany, x132) saw a cloudy spot in Aristarchus crater. Olbers (Breman, Germany, x44 refractor) though thought this description was due to the magnification used, however they themselves did report a 6th magnitude star (Mems. R.A.S., 1-159).(25). 3-4'in diameter. Browne (England) also saw the event. The Cameron 1978 catalog ID=84 and weight=5. The ALPO/BAA weight=4.
On 1988 Feb 20 at UT22:25-22:34 H. Rodriguez Moreira (Fortaleza, Brazil, 4" refractor) observed a rapid rise in brightness at 22:25UT in Promintorium Olivium. About 4 minutes after this the brighness fluctuated 3 times and the TLP faded in 9 minutes after it started, returning everything to normal. "Bluish light point on darkside of it" - apparently a Greek observer (Aguirre) observed a flash but no date was given. The Cameron 2006 catalog ID=317 and the weight=3. The ALPO/BAA weight=3.
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 1821 Feb 06 at UT 18:00-19:00 At 18:00UT H. Kater (London, UK), Olbers (Bremen, Germany), Browne (UK), commented that Aristarchus looked like a 6-7th magnitude lumninous star, some 3-4' in diameter. At 19:00UT Aristarchus looked like a cloudy spot according to Ward and Bailley (England, large telescope, x80). The Cameron 1978 catalog ID= 84-85 and the weight=5. The ALPO/BAA weight=3.
Schroter observed Aristarchus to be extraordinarily bright on the dark side of the Moon. Cameron 1978 catalog ID=30 and weight=4. ALPO/BAA catalog weight=2.

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 1990 Aug 26 at UT 02:30-03:30 W. Cameron (Sedona, AZ, USA, 8" reflector, x110 and x220) observed that Proclus and Piccolomini craters both had a pink colour inside them. At a higher magnification of x220 Piccolomini was still pink and it was stronger on the central peak's wesern side. The cameron 2006 catalog ID=407 and the weight=3. The ALPO/BAA weight=1 as the Moon was not above the horizon at the date and UT given.
On 1990 Aug 26 at UT 02:30-03:30 W. Cameron (Sedona, AZ, USA, 8" reflector, x110, x220, seeing=good) observed that the north wall of Proclus crater was the brightest part of the crater, indeed very bright. Proclus and Picolomini had pink colours inside them. CED brightness measurements were as follows: "Proc. at 100x 4.0, 4.0; at 200x 3.4, 3.4; Theop. 3.5, 3.9; 3.5; Herc. 2.5, 2.75; 3.5; Atlas 2.8, 2.5, 3.0; Posidonius 3.0." The Cameron 2006 catalog ID=407 and the weight=3. The BAA/ALPO weight=1 as the Moon was not above the horizon at the UT given.
On 1990 Aug 26 at UT 02:30-03:30 W. Cameron (Sedona, AZ, USA, 8" reflector, x110 and x220, seeing=good) observed that the west wall of Theophilus crater was red (on terminator). However Posidonius was also on the terminator and no colour was seen elsewhere along the terminator, however Proclus and Piccolomini had pink interiors. At a higher power of x220 a prismatic effect was seen on the terminator in Theophilus and opther craters - "even on W rim of a crater due W of Theoph.". CED measurements of Theophilus... 3.5, 3.9, 3.5. The Cameron 2006 catalog ID=407 and the weight=3. The ALPO/BAA weight=1 because the Moon was below the horizon at this time.
On 1867 Apr 09 at UT 19:30-21:00 Elger(Liverpool? UK, 4"? aperture telescope) observed that Aristarchus was shining like a 7th magnitude star-like point, becoming fainter, almost extinguished at 9PM. He had seen lights before but never so strong. The Cameron 1978 catalog ID=151 and he weight=4. The ALPO/BAA weight=2.
Nebulous appearance. Cameron 1978 catalog assigns an ID No. of 12 and a weight of 1. ALPO/BAA catalog assigns a weight of 1.
Censorinus 1959 Sep 08 UT 22:45-23:50 Observed by Jean Nicolini (Brazil) "Much brighter than Proclus" NASA catalog weight=2. NASA catalog ID #721. ALPO/BAA weight=2.
2018 Jun 19 UT 04:00 G. Cross, using a 60" f/16 Cass, Strehl > 0.9, under descent seeing conditions, found that the ghost crater was not visible - was this an obscuration or just normal apeparance? ALPO/BAA weight=1.
Messier 1981 Feb 10 UT 19:20-20:10 TLP discoevered by Hedley Robinson (Devon, England) "Messier was brighter than Aristarchus in both red and blue filters and also appeared indistinct, later becoming invisible - lost in a bright streak. In comparison Aristarchus was clear. Another observer, Amery confirmed that Aristarchus was sharp in appearance but Messier certainly was not. Cook likewiese found Messier not to be as sharp as Messier A dueto a big shadow in Messier A. Pedler found that the sun facing wall of Messier was OK but that the shadow was changing from black to grey periodically at intervals of 2-3 minutes to a few seconds. By contrast he found that Messier A remained quite well defined. He tried red and blue filters but found no blink effect. At 20:23UT Pedler found that the shadow had stabilized to a shade of "mid grey" although remaining ill-defined. North also found that Messier A was distinct but Messier itself was ill-defined. Moore found the same thing but thinks that this is normal for Messier under this illumination to appear indistinct. More also saw the grey interior shadow. Price saw similar appearance to Moore and suspected that this was normal for this stage in illumination. Ratcliffe suspected everything normal - just commenting that Messier was smaller and no detail in comparison to Messier A. Madej and Taylor provided a sketch that showed again a grey interior and merging with the east wall/mare. Foley found Messier's pale grey interior to be un- focusable but in comparison Messier A was sharp. He says that he would expect a grey interior and the east wall to merge with the mare. However the complete loss of deatil and variability were not normal. Cameron comments that the Kuiper atlas confirms the fuzzy indistinct appearance of Messier and that a Lunar Orbiter picture shows a grey shadow. The Cameron extended catalog weight=5. The ALPO/BAA weight=2.
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.

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 1980 Jul 23 at UT22:00 G.W. Amery (Reading, UK, 8" reflector, x144 and x207, seeing=III-V and transparency=fair) found that the interior shadow was a light grey. BAA TLP coordinator (Foley) suggests that this was light reflecting from the illuminated walls? Cameron 2006 catalog TLP ID=102 and weight=1. ALPO/BAA weight=2.
On 1990 Jan 08 at UT00:55 D. Weier (Sun Praire, WI, USA, 12.5" 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 LTP. Darling had never seen such effects before (flickering implies a medium in it)." The Cameron 2006 catalog ID=387 and the weight=3. The ALPO/BAA weight=3.
On 1977 Apr 29 at UT21:40-23:20 an unknown UK observer reported a TLP in Gassendi crater. The following are reports by observers attempting to confirm activity: J.W. Napper (Didcot, UK, 30cm reflector, x287, Wratten 25 and 44a, conditions clear 5+) received a telephone alert call at 22:00 but the sky was cloudy until 22:30. An initial look revealed nothing unusual, then at 22:54 he observed a colour blink just inside the north wall, appearing bright in red and normal in blue or white light. No loss of detail seen and the effect lasted only 2 minutes. A sketch was made. However the observer stresses that the very bad seeing casts some doubt on this observation. L. Fitton observed using a 8.5" reflector, with Moon blink device at x200, seeing was I- II. All areas negative, including Gassindi from 21:40-21:55 and again 22;00-22:25 and finally 22:50-23:30 negative. Mike Brown (Huntington, York, UK, 30cm reflector, x220 and x350, seeing 3-4/5, and transparency 5/5) - observed from 22:00-23:25UT no colour seen, nor obsecuration, all filters negative, despite seeing a lot of fine setail inside this crater.
Gassendi 1976 Oct 04 UT 20:55-20:58 Observed by Robinson (Devon, England) - observer noted that the east outside wall was bright in red and normal in blue. Note that the Moon was 30 deg above the horizon at the time of the observation. The crater returned to normal at 20:58. Also seen by Moore (Selsey, UK) and Foley (Kent, UK). At 21:25-21:50 D. Sims (Dawlish, UK, 25cm reflector, x300, seeing IV and some cloud at times) noticed a possible obscuration over the southern part of Gassendi. He had been observing earlier at 18:40-19:30 but had not detected a TLP in Gassendi then. 22:11UT Robinson notices that the spot outside the east wall is again bright in red., though by 22:25 it had faded and was gone by 22:28UT. The Cameron 1978 catalog further quotes: "Vivid red spots & general red color seen around rim by 2 obs. At 2209h blood red small area was seen. 1 h later the most westerly (IAU?) of the peaks had become hazy white all other areas were sharp. (Indep. confirm.)." Cameron 1978 catalog weight=5 and catalog ID #1454. The ALPO/BAA weight=3.

Brightness 9 and adjacent plain was of brightness 6.5. The Cameron 2006 catalog ID=308 and the weight=3. The ALPO/BAA weight=2.
Gassendi 1966 May 01 UT 19:30-00:21 Observed by Sartory (UK, 8.5" reflector, x500, S=G), Moore, Moseley (Northern Ireland, 12.5" reflector x350, S=E) and by Corralitos Observatory (Organ Pass, NM, USA, 24" reflector + moon blink) "Eng. moonblink & obscuration, also vis. confirm (Moore & Moseley alerted by Sartory. Corralitos MB did not confirm. - but they may not have been observing at the ame time?)." NASA catalog weight=5. NASA catalog ID #932. ALPO/BAA weight=4.
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.

Gassendi 1939 Sep 25 UT 01:30 Observed by Haas (New Mexico? 12" reflector?) "NE part pf c.p. had I=9.4 comp. with I=6.4 (normal? in # 458. under similar obs. cond. (& phase. thus real diff.)" NASA catalog weight=4 (high). NASA catalog ID #462.
On 1989 Sep 12 at UT00:58-02:25 D. Darling (Sun Praire, WI, USA, 12.5" reflector, x159, S=7/10) observed similar light conditions to 1989 Jul 15. 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.
Aristarchus 1975 Oct 16 UT 20:00? Observed by Foley (Kent, England, 12" reflector) "Deep blue-viol. spot in NW (IAU?) interior corner." NASA catalog weight=3. NASA catalog ID # 1413. ALPO/BAA weight=1.

Moon 1967 Apr 22 UT 02:30 Observed by Dunlap et al. (Corralitos Observatory, Organ Pass, NM, USA, 24" reflector) "UV excess as in # 1029. Gradient was 10# at term. to 25-30$ at subsolar pt. (153 deg long)." NASA catalog weight=5 (very high). NASA catalog ID #1031.
On 1980 Jul 24 at UT22:10-22:55 P. Moore (Selsey, UK, 15" reflector, x360 and x400) found an area just south east of the central peak (and upto the wall) to be quite dark in blue light, but normal brightness in red light or in white light. All other features were normal colour- wise. At 22:55UT Tycho was normal again. Cameron 2006 catalog ID=103 and weight=4. ALPO/BAA weight=3.
On 1982 Dec 27 at UT 23:00 M. Price (Camberley, Surrey, UK, Seeing=III and transparency=good) observed that Piazzi-Smyth was brighter than Mon Piton at 23:00. Photographic atlas was checked to verify that this was abnormal. The Cameron 2006 catalog ID=193 and weight=4. The ALPO/BAA weight=2.
On 2004 May 02 at UT03:24 M. and L. van Son (Bremerton, WA, May 1st 7:24PM PST) saw a naked eye flash on the Moon. The observers were glancing up at the Moon in daylight when they saw a bright white flash (observer and his wife together) in the upper/mid Mare Serenitatis region, west of the crater Posidonius. "Larger than how Venus appears". "It was a quick flash like white, intense lightning. I'm not sure how to report degrees of arc but if the face we see is 900, and we start from the east then the flash occurred about 225 arc seconds to the west. This was observed by the naked eye, with clear skies between us and the moon." The observers checked for signs of aircraft vapour trails but could not see any. There is a possibility that it could have been sun glint from an Iridium satellite, but this needs to be checked out and usually these last longer than the observed effect. It would be useful to obtain whole Moon images under the same illunination and libration so that we can judge this observation properly. The ALPO/BAA weight=4.
Cobra Head 1966 May 02 UT 20:05 Observed by Sartory (England, 8.5" reflector x400) "Eng. moon blink detected red spots, seen visually also". NASA catalog weight=4 (good). NASA catalog ID #934.

eclipse an unconfirmed impact flash on the Moon. The ALPO/BAA weight=3.
Moving glows seen around the middle of the disk during a lunar eclipse. It is possible that the TLP referred to might have been from the 1783 Mar 18 eclipse instead?
On 1978 Sep 16 at UT 18:28-18:57 G.Searle (Concord, Sydney, NSW, Australia, 8" reflector, x100, x160, S=III) observed a bright star-like point on the western (IAU) edge of Mare Tranquilitatis (x100) that appeared unlike any other crater and a check of the location revealed no suitably bright crater in that region (from a map?). Changed to a higher power (x160) and it was still there, but not as conspicuous. Observer thinks that this may have been due to the Moon's low altitiude (16 deg) and the seeing. At 18:35 he compared it to the brilliant crater Proclus and found the star-like point to be 75% of the brightness of Proclus. Ken Wallace (Australia) had been taking photos and observed the object at 17:37.5UT. The object gradually faded over the next 15 minutes and by 18:52UT could only be seen in averted vision at x100.

On 1964 May 26 UT 04:10-04:35 Bartlett (Baltimore, MD, USA, S=5, T=5). observed that Aristarchus had a strong blue-violet glow on the east wall and EWBS, with a strong violet tinge on the nimbus. Crater was hazy, could not focus it in red, green or blue light. The Cameron 1978 catalog ID= and weight=4. The ALPO/BAA weight=2.
On 1982 Jan 09 at UT18:46-21:42 P. Moore, (Selsey, UK) and others found that Aristarchus and Plato changed in brightness and colour during a lunar eclipse. Aristarchus was especially bright during the lunar eclipse. Cameron 2006 catalog ID=162 and weight=5. ALPO/BAA weight=3.
On 1982 Jan 09 at UT 18:46-21:42 P. Moore (Selsey, UK) and other observers noted Censorinus was exceptionally bright. Cameron 2006 catalog ID=162 and weight=5. ALPO/BAA weight=2.
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.

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 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.
On 1915 Mar 22 at UT 11:30-12:30 Jackson (France?) observed Aristarchus during a total lunar eclipse: "Dur. totality there remained vis. to the NW a red luminous pt. not much larger than Mars & of the same color". (date & time is old system and has been converted by Cameron). The Cameron 1978 catalog ID=343 and the weight=3. The ALPO/BAA weight=3.
On 2000 Jun 16 UT 20:37 C. Brook (Plymouth, UK, 60mm refractor, x117 & x40, seeing good, transparency excellent) observed abright spot on the north rim of Mare Crisium (57E, 25N). 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. It extended its radiance to adjecent craters (e.g. Herodotus) all throughout totality. At the subsequent eclipse in September 1895 it was seen to be inconspicuous. the Cameron 1978 catalog ID=283 and the weight=5. The ALPO/BAA weight=4.

On 1989 Feb 20 at UT 16:55 G. Kolovos (Thessolonki, Greece) photographed in one photograph (out of 3) during a lunar eclipse, some bright patches below (south?) of the crater that were not in the other photographs (UT16:56:32 or 16:58:56). Foley commented that the photographs were grainy so cannot tell for sure. The Cameron 2006 catalog ID=356 and the weight=1. The ALPO/BAA weight=1.
On 1967 Apr 24 at UT 11:47-12:08 Osawa (Hyogo, Japan, 6" reflector, x50) observed during totality, two luminescent spots (started 20 min after beginning of totality) near Grimaldi. Location not certain because of dimnesa of umbral shdaow and lunar features. (bright spots in Sven Hedin?). Colour was bluish rather than yellowish and magnitude < 9. The Cameron 1978 catalog ID=1035 and weight=3. The ALPO/BAA weight=2.

In 1902 Apr 22 at UT 22:00 (Cameron estimated UT) Zlatinsky (Russia, 3" refractor?) observed Aristarchus to have some luminescence during a total lunar eclpise. Mid eclipse was at 18:53. The weight=2. The ALPO/BAA weight=1.
In 1949 Apr 13 at UT 05:00 Vreeland and others (Mill Valley, CA, USA, 4.5" refractor) observed in Aristarchus a brilliant star-like point just after 3rd contact. This was not seen before or during totality. He thinks that it was a high peak catching the sunlight before the rzst of the surface. It remained bright but larger as the sun hit it. The Cameron 1978 catalog ID=517 and the weight=1.
Bright light seen during eclipse. Date given as 8th but the Full Moon was on 6th according to Goldatine's "New & Full Moon's"). ALPO/BAA catalog weight=1. Cameron catalog weight=3. Cameron Catalog ID: 4. Julian date 1096 Aug 06. Gregorian date 1096 Aug 12.
On 1905 Aug 15 at UT 03:30 Rey (Marseilles, France) observed Tycho during a lunar eclipse to be visible, indeed it was described as brilliant during the eclipse (mid eclipse 03:31UT). The Cameron 1978 catalog ID=322 and weight=1. The ALPO/BAA weight=1.

On 1982 Jul 09 at UT 01:05-01:25 P. Moore (Selsey, UK, 12.5"? reflector, seeing III) found that Aristarchus was very bright and slightly blue. Cameron comments that Moore's eyesight is not very blue sensitive. The Cameron 2006 catalog ID=175 and weight= 4. The ALPO/BAA weight=2.
On 1982 Jul 09 at UT01:05-01:25 P. Moore (Selsey, UK, 12.5" reflector, seeing=III) found that Grimaldi A was the 2nd brightest feature on the Moon, and that there was colour detected with a Moon blink device on the floor of Grimaldi. The Cameron 2006 catalog ID=175 and the weight= 4. The ALPO/BAA weight=3.
On 1979 Sep 09 at UT08:00-08:15 D. Darling (Sun Praire, WI, USA, 12.5" reflector, x75 and photography used, seeing 4/10 and the Moon's altitude was 45deg) photographed Romer crater and recorded two adjacent bright cigar shaped objects - these were the same size as an observation made in 1987. Darling believes that these are ridges. Cameron comments that in LO-IV 192-3,2 a ridge is revealed on the inside wall that matches the description. Cameron 2006 catalog ID=66 and weight=2. ALPO/BAA weight=1.
Macrobius 1898 Dec 31 UTC 20:00 Observed by Goodacre (Crouch End, England, 12" reflector) "Interior nearly filled with shadow at sunset. Inner E.wall very bright-a distinct penumbral fringe to black shad. cast on it from W.wall. Seen best using high powers. (Firsoff & MBMW give date as just 1895 but must be wrong-phase - see app.ref.)" NASA catalog weight=4 and catalog ID #304. ALPO/BAA weight=2.
On 2005 Oct 21 at UT 13:07-14:27 R. Gray (Winnemucca, NV, USA, 15cm F/9 refractor, x228, seeing 4-5, transparency 5-6) observed a possible TLP in Macrobius. His report is as follows: "Blinked Macrobius with Wratten Filters Blue 38A and Red 29. Macrobius became almost invisible through the Blue 38A and essentially the same as in white light through the Red 29. The interior of the crater was completely in shadow. The only part of the east wall that was visible was an apparent high point still in the sun and seen as a bright point of light. This faded into darkness before 13:56UT. No sign of any illumination of the east wall crater interior or the interior of the west wall was seen during the observation period. The outer west wall was a rough looking, complicated mix of deep shadow and illuminated sunlit terrain." The observer concluded that there was not a TLP - although he did get a filter reaction, this may have been due to the different densities of the filters? ALPO/BAA weight=2.
On 1989 Aug 20 at UT13:55 M. Lucas (Melbourne, Australia, naked eye) witnessed a "pin-point flash" in the middle of the lower right quadrant of the Full Moon. Foley suspects that this was in the Proclus region? The Cameron 2006 catalog ID=374 and the weight=2. The ALPO/BAA weight=2.
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.
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.
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.
