The external brightness was extended to the east wall at a clock position of 9 O'clock, but did not go outside the rim. It was less bright at the 11 O'clock position. The Cameron 2006 catalog ID=236 and the weight=3. The ALPO/BAA weight=2.
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 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.
1977 Apr 23 UT19:30-22:45 Foley (10.75" Newtonian and 4.5" refractor, seeing II, transpaency excellent) saw som every large variations in the brightness of Aristarchus whereas other features in Earthshine remained stable. Aristarchus was seen to be blue/violet. ALPO/BAA weight=2.
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.
On 1972 Dec 11 at UT22:28 Cernan, on board Apollo 17, saw a flash on the east rille in Mare Orientale (88W, 20S) as he orbited the Moon. The Cameron 1978 catalog weight=1354 and the weight=3. ALPO/BAA weight=2.
On 1891 Nov 07 at UT=19:00 d'Adjuda of Lisbon, Portugal (seeing fair) whilst observing Aristarchus noticed that the crater appeared as very distinct luminous point in the dark. Cameron 1978 catalog ID=275 and weight=3. ALPO/BAA weight=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.
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. 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.
Theophilus 1964 May 18 UTC 01:05-01:15 Observed by Dieke (Baltimore, MD, USA, 6" refractor, x125) "Crescent of crsimson color on SW between rim & flor. Was not present at 0500, nor did it reappear from 0115 to 0245h" NASA catalog weight=3 (average). NASA catalog ID #812.
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.
Alphonsus 1965 May 08 UTC 05:47-05:59 Observed by McLaria (Huntsville, Alabama, USA, 16" reflector, S=9) "Light flashes on c.p. color detected by Trident M.B." NASA catalog weight=5 (very high). NASA catalog ID # 875.

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.
On 1993 Jun 27 at UT 19:55-20:21 and 20:24-21:04) D. Kane (England? UK, 4" refractor) discovered that the central peak of Alphonsus crater was very bright. The central peak was also brighter in red than in blue light. However G. North (Herstmonceux, UK, 6" reflector, x135, seeing V-III) and M. Cook (Frimley, UK, 4" reflcrctor, x10, seeing=III) observed that the central peak was normal, however they did not use filters. The Cameron 2006 catalog ID= and weight=3. The ALPO/BAA weight=2.
Proclus 1972 Aug 17 UT 20:05-21:10 Observed by Haiduk (13.25E, 52.5N, 60mm refractor, S=1, T=3) "Well visible bright area at the NE wall, end of event uncertain for seeing became poor" Hilbrecht & Kuveler Moon & Planets (1984) Vol 30, pp53-61.

ALPO/BAA weight=1.
On 1867 Apr 12 at UT 19:30-21:00 Elger (Liverpool? UK, 4" aperture telescope) observed Aristarchus in Earthshine "grew fainter 7th mag. star; much fainter in last 15 min. & barely perceptible at 9PM. Had seen something similar on former occ." The Cameron 1978 catalog ID=152 and the weight=4. The ALPO/BAA weight=2.
In 1824 Jul 04 at UT23:00? Emmett (England, UK) observed a star-like light on the rim (in the dark). The Cameron 1978 catalog ID=100 and the weight=3. The ALPO/BAA weight=2.
Eratosthenes 1976 Jun 06 UT 02:01 Observed by Bartlett (Baltimore, MD, USA, 3" reflector x54-300, S=5, T=5) "Bowel was full of shadow but a small 5 deg bright spot on NE floor. Nothing seen in 1975 at nearly same col. but shadow was deeper." NASA catalog weight=4 (high). NASA catalog ID #1432.
Plato 1964 May 20 UT 01:00-01:30 Observed by Bartlett (Baltimore, MD, USA, 2.4" refractor x117, S=6, T=5). "Orange-red color on W. wall. Vivid" NASA catalof weight=4 (high). NASA catalog ID #813.
Alphonsus 1990 Feb 03 UT 18:00-18:23 Observed by A.C. Cook (Frimley, UK, CCD video camera, seeing III-IV). At 18:06 W and SE dark floor patches, equally dark, but at 18:10 and 18:23 the W dark patch was the darker of the two?. Between 18:06 and 18:23 and a bright patch to the north of the central peak brightned slightly wrt the its surroundings. However seeing conditions worsened as the observing session progressed, and in view of this the ALPO/BAA weight=1.
Tycho 2003 May 09 UT 21:04 Observer Brendan Shaw (UK) "CCD image of central peak - Sun's altitude suggested that this should not have been directly illuminated this early - may have been from secandary reflectance off illuminated W wall?" ALPO/BAA weight=1.
Plato 1925 Jun 20 UT 20:00? Observed by Markov (Russia) "Light bands in bottom seen in shadow & did not seem to be elevations. These have been seen 5X from 1913-1922." NASA catalog weight=3. NASA catalog ID #391. ALPO/BAA weight=2.
Alphonsus 1966 Apr 28 UT 21:58 Observed by Smith (England, 10" reflector) and Corralitos Observatory (Organ Pass, NM, USA, 24" reflector+Moon Blink) "Reddish patches, (not confirmed at Corralitos with MB tho they give feature as Gassendi in their report)." NASA catalog weight=2. NASA catalog ID #930. ALPO/BAA weight=1.
Alphonsus 1990 Feb 03 UTC 20:05-21:22 Observed by Brook (Plymouth, UK, 10" reflector) "Brightness variance noted". The Cameron 2006 catalog does not have an entry for this observation. The ALPO/BAA weight=2.
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.
Alphonsus 1966 Nov 22 UT 03:17-03:40 Observed by kelsey (Riverside, CA, USA, 8" relector x300) "Seen first with (Eng.) moon blink, red filter but not in the green. Not seen at 03:42h" NASA catalog weight=4 (high). NASA catalog ID #998.
Aristarchus 1976 Jun 06 UT 21:30-21:40 S.Spencer and R. Hunt (60mm refractor, x150 and x60) both observed red on the SW corner of Aristarchus. ALPO/BAA weight=1.
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.
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.
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.
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.
On 1989 Jan 16 at UT 20:00 G. North (Herstmonceux, UK, 30" reflector) observed Toricelli B to change in brightness and found colour in it. A 10 minute exposure spectrum was taken (Cameron does not have information on whether anything unusual was recoeded) before clouds obscured the Moon. Normally a 30 minute exposure would be needed. The Cameron 2006 catalog ID=345 and the weight=3. The ALPO/BAA weight=3.
Aristillus 1939 Sep 23 UT 01:00 Observed by Haas? (New Mexico?, USA, 12" reflector?) "Dark area in W. part of floor had I=1.3. comp with I= 1.3, 3.7, 4.0 in #450, 454, & 459, respectively. (albedos disagree at same phases, so are real anomalies). (normal here?)." NASA catalog weight=4 (high). NASA catalog ID #461.
Alphonsus 1966 Apr 20 UT 22:28 Observed by Smith (Nottingham, England, 10" reflector) Reddish patch possibly detected on SE flank of central peaks, but more dubious than that from 28th Apr. ALPO/BAA weight=1.
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.
On 1882 May 27 ay UT 20:00 an unknown observer (10" reflector) saw a bright luminous ray near west (astronomical?) wall on floor of Plato. Cameron suggests sunlight between peaks?. The Cameron 1978 catalog ID= 233 and weight=0. The ALPO/BAA weight=1.
On 1980 Jul 22 at UT20:08-21:50 G.North (Sussex, UK, 8" reflector, x144 and x207, seeing III-V and transparency fair) suspected an obscuration on the north and north west wall. The effect came and went. May have been due to seeing and image contrast? Cameron 2006 catalog ID=101 and weight=1. ALPO/BAA weight=1.
On 1964 Jan 24 at 20:00? Scarfe (UK) obtained spactra showing luminescence? The Cameron 1978 catalog ID=796 and weight=5. The ALPO/BAA weight=3.
Ross D 1966 Nov 23 UT 04:50-05:02 Observed by Cross (Whittier, CA, USA, 19" reflector, x250 & 2390, S=4-5 (sometimes 6), T=4, excellent contrast) Activity level 5, eastern third of Ross D's circumference possibly partly obscured. ALPO/BAA weight=1.
On 1987 Oct 03 at UT 01:0?0-02:00 R. Manske (Brooklyn, WI, USA, 8" reflector, x226) observed sunlight glinting of the walls in spectacular display of colours. White (even gold) was seen at the centre, and blue on the top most part of the rim. The white (or gold) band was thin in comparison to other bands. The observer suspects that this effect was terrestrial atmosphere related. Cameron 2006 catalog ID=307 and weight= 0. ALPO/BAA weight=1.
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. ALPO/BAA weight=3.
Plato 1998 Mar 08 UT 19:30-20:10 S. Beaumont (Windermere, UK, 30cm reflector, Meade 23A and 38A filters, seeing III, transparency fairly good, some haze) observed a whitish misty effect seen bordering the shadows of the SE rim. It appeared intermittently and was not seen in the violet or red filters. Observers wonders if it could have been an effect associated with the Earth's atmosphere, which was unsteady with some haze. However, other craters appeared normal. The ALPO/BAA weight=1.
Gassendi 1966 Apr 30 UT 21:30-23:28 Observed by Sartory, Ringsdore (England, 8.5" reflector, S=E), Moore, Moseley (Armagh, Northern Ireland, 10" refractor, S=VG), Coralitos Observatory (Organ Pass, NM, USA, 24" reflector, Moon Blink) "English moon blink system detected red spots with vis. confirm. Ringsdore says no color but saw obscuration. (LRL 60-in photos showed nothing unusual by my casual inspection). Indep. confirm. (even E. wall was in dark). Corralitos did not confirm by MB." N.B. event had finished by the time Corralitos came on-line. NASA catalog weight=5. NASA catalog ID #931. ALPO/BAA weight=4.
Eratosthenes 1968 Nov 01 UT 01:50-02:06 Observed by Chilton (Hamilton, Canada, 12" reflector, 300x) "Red glow in the crater. Weak blink beyond ESE (IAU?) wall. Visually, area would not focus & gave impression of fog cascading down slope, but no motion was vis. (Moore has misprint in time in his cat. extension -- should be 0150-0206)." NASA catalog weight=3. NASA catalog ID 1106. ALPO/BAA weight=3.
Plato 1906 Mar 06 UT 22:00? Observed by Fauth (Germany? 6" refractor) "Color (brightness?) greatly enhanced as it was to be on the next nite" NASA catalog weight=3 (average). NASA catalog ID #324.

The ALPO/BAA weight=1.
Peice A (Swift=IAU name?) 1927 May 12 UT 22:03 Observed by Wilkins (England, 15" reflector) "Complete obscuration of crater. Saw no trace of it. It was vis. May 11 & faint on May 13. 3x in 1948 Moore saw whole area misty gray & devoid of detail, whereas surroundings were sharp & clear. Birt also found it invis. at times in late 1800's" NASA catalog weight=4. NASA catalog ID #394. ALPO/BAA weight=3.
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 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 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.
Aristarchus visible just past terminator. West wall was brighter than normal. Bright flash seen in/on NW wall - apparently in the same place as Pedler's May 17th sketch. Cameron 2006 extension catalog ID=146 and weight=4. Observed by M. Price of Camberley, Surrey, UK with a 6" reflector and a Moon Blink device. Seeing=III.
Plato 1981 Jun 13 UT 20:48-21:08 Observed by Price (Camberley, England, 152mm reflector, seeing III) Possible Moon blink (red) seen on north wall. Also the craterlets on the floor could be seen despite the observing conditions not being optimal. BAA Lunar Section observation. Cameron 2006 extension catalog ID=146 and weight=4. ALPO/BAA weight=3.
On 1984 Jan 14 at UT 20:00 P. Moore (Selsey, UK) observed that Aristarchus was brighter than it normally is at sunrise. No quantitative measurements were made though. The Cameron 2006 catalog ID=238 and weight=3. The ALPO/BAA weight=1.
Observer noted a bright spot on the interior west wall that seemed brighter than what they would have expected. unfortunately the precise time of this observation was not recorded so the moon-rise and midnight UT values are used to place a limit on the time of observation. Images by Shaw taken at UT 1754, 18:45 and 23:13 do not exhibit the effect.
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.
On 1987 Oct 04 at UT 02:20 D. Darling (sun Praire, WI, USA, 12.5" reflector, x170, S=8, VG, T=5) obtained the brightest measurement he had ever recorded on the northern rim of Proclus. Brightness 9 and adjacent plain was of brightness 6.5. The Cameron 2006 catalog ID=308 and the weight=3. The ALPO/BAA weight=3.
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. Brown saw intense white spot NW of crater wall" NASA catalog weight=5. NASA catalog ID 933. ALPO/BAA weight=4.
M. Cook of Frimley, UK observed a brightening of the crater during this observing session. The cameron 2006 extended catalog ID=346 and weight=3. ALPO/BAA weight=2.
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.
Gassendi 1967 Mar 22 UTC 19:39-19:43 Observed by Mosely (Armagh, N. Ireland, 10" refractor, x360) "Red color & blink strongly suspected in small area centred on junction of 3 clefts 1/2 way from c.p. & ESE wall. Well-defined & did not note change during obs. period. Clouds terminated obs. till 2120 when it was not seen." NASA catalog weight=3 (average). NASA catalog ID #1018.
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.
G. Ward (a lunar observer for 15 years) observed an area just south west of Mersenius C to be blurred and in a greenish cloud. The green colour was more like that of dead grass than one gets from a neon bulb. The effect was seen from 04:50-04:57UT, but could have been going on before it was first noted at 04:50-UT. Seeing was 6-7/10 4" Refractor (2 element). refractor had been used hundreds of hours before (over a 10 year period) with no similar colour was seen. The observer checked other areas but did not see any similar effects. They also rotated and changed eyepieces, but this made no difference to the TLP. The TLP site seen was picked up on an image taken earlier at 04:47UT by W. Bailley, from Sewell, NJ, USA. Unfortunately the area concerned, a mountain on the image, was saturated and so we cannot tell if a colour was present there and the seeing was poor.
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.

Aristarchus 1919 Jun 10 UT 19:00-19:30 Observed by Lapshin (Russia) a "Greenish-yellow light shone from inside the crater for 1/2 hr. after which it returned to normal. Violet tint on W. bank & surrounding area & the dark color of the saddle & dark spot were distinct. Term. slightly E. of Herodotus. (Ast. E)=IAU W." NASA catalog weight=3. NASA catalog ID #372. ALPO/BAA weight=3.
In 1949 Nov 03 UT 01:06 J.Bartlett (3.5" refractor, x100) noted that the floor of Herodotus was very dark, the east wall was very bright, and the floor contained a central bright peak. The BAA/ALPO weight=3.
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.
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 Foley used a 12" refletor. Mosely experienced II seeing and good transparency. Cook had III seeing and also good transparency. P. Grego made an observation this night too. The ALPO/BAA weight=2.

Foley used a 12" reflector and seeing was III-V. ALPO/BAA weight=3.
On 2009 Jan 09 at UT 20:00 P. Brierley (UK) took a CCD image of the Aristarchus area - P.Grego upon examining this comments that he thinks that Schiaparelli crater looked "muted in brightness -- it is normally quite bright to look at". Though Grego comments that it might have something to do with the image processing aplied to the image. The ALPO/BAA weight=1.
