On 1993 May 28 at UT 21:02-21:30 M.C. Cook (Frimley, UK, 3.3" Questar telescope, x80-x130, atmosphere hazey - poor transparency) noticed that the east side rims were slightly fuzzy and suspects that this might have been due to the illumination angle. A.C. Cook (Frimley, UK) obtained some CCD images that revealed that the effect was to some extent still there one hour later. The Cameron 2006 catalog ID=461 and the weight=5. The ALPO/BAA weight=2.
Large plume-like diffuse cloud over central peak, very large compared to central peak (@ approx 30km diameter) with intensity much different from other parts. Brightness between walls and shadowed floor. Would take 3 minutes to collapse, so continuously fed. 13-14 days later, at SS, central peak was normal. Kuiper took photos after Kozyrev's observations, but saw nothing abnormal. Drawing. Haas saw nothing in 12inch reflector at the time. Cameron 1978 catalog TLP ID=705 and weight=4. ALPO/BAA weight=2.

Louderback (South Bend, WA, USA, 4" refractor, x95, seeing=1-2-1 and transparency=4) detected a change in brightness of Mons Piton point D (his designation) during 04:56- 04:59. The whole of the east slope was affected - initially bright and then faded and there was a blue colour (detected with filters). The variabilty was 8-11sec (Cameron suspects atmosphere as the altitude was low). The brightness stabilized at 05:12UT, but variability resumed until observing finished. As a comparison Aristillus was not seen to change. The Cameron 2006 catalog ID=287 and the weight=1. The ALPO/BAA weight=1.

On 1981 Aug 09 at UT05:08-05:21 D. Louderback (South Bend, WA, USA, 3" refractor) found that the bright patch in the southern part of Eimmart, could only be seen well in red light (this is between A, C and D in his feature notation) i.e. 5 brightness values higher than in white or blue light. Indeed in white light this bright area was closer to the east wall bright spot. The Cameron 2006 catalog ID=149 and weight=4. The ALPO/BAA weight=2.
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.

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.
On 1994 Apr 19 at UT 22:00 R. Knopp (Berlin, Germany) noticed a darkening of the interior of the crater Atlas. The ALPO/BAA weight=1.

No interposition of dates works e.g. 13th or 1926 or Dec 26 1923. Only Dec 3 1927 is feasible as it would be just after 1st Q. & more similar to the May obs.)" NASA catalog weight=4? NASA catalog ID #396. ALPO/BAA weight=2.
On 1988 Mar 27/28 UT23:30-00:30 M.C. Cook (Frimley, UK, 12" reflector) found Censorinus to have a "foggy/fuzzy" appearance that was not seen in adacent areas. The Cameron 2006 catalog ID=321 and weight=4. ALPO/BAA weight=2.
On 1988 Mar 27/28 at UT 23:30-00:30? M.C. Cook (Frimley, UK, 12" reflector) noted that the crater Proclus was bright visibly, but the CED brightness measurement gave the same brightness as Censorinus crater. The Cameron 2006 catalog ID=321 and the weight=4. The ALPO/BAA weight=2.

On 1968 Oct 01 at UT 21:00? Bartlett (Baltimore, MD, USA) and Beck (Ohio, USA, x437) observed lack of detail on the floor of Plato, however the wall of the crater was easily resolved. Cameron says that this was an independent confirmation. The Cameron 1978 catalog ID=1092 and weight=5. The ALPO/BAA weight=3.
On 1986 May 18 at UT 20:45-22:25 M. Mobberley (Suffolk, UK, seeing II- IV) found that the central craterlet of Plato was an ëasily seen "white splodge" although it was quite difficult to see when imaged with video. Foley and Cameron comment on IR sensitivity of the CCD camera used. The Cameron 2006 catalog ID=285 and the weight=1. The ALPO/BAA weight=1.
On 1988 Jul 24 D. Darling (Sun Praire, WI, USA, 12" reflector, x150, S=7/10, T=3) observed the following in Proclus: "At 0213 the previously observed gray area was 1/3 of July 22 and V shaped and fanned out across the floor. Could see hint of knot seen before. Craters named in 7/23/88 (#319) were all normal this time too". Is it possible that this report refers to the crater "Gray" rather than "Proclus" as the column field suggests in the Cameron catalog? The Cameron 1978 catalog ID=333 and weight=5. The ALPO/BAA catalog weight=2.
On 1963 Nov 27 at UT 03:00 Olivarez (New Jersey?, USA, 17" reflector) and Fisher (Colfax, CA, 8" reflector, x300) observed a red glow in Anaximander in the dark part of the Moon. The Cameron 1978 catalog ID= 784 and weight=5. The ALPO/BAA weight=3.

Om 1987 Sep 04 at UT 03:00 J. Caruso (Middletown, CT, USA, 3" refractor, x155, S=6/10 and T=8/10) found that Bianchini G was not visible, however Heraclides E, Helicon G, and indeed many other smaller craters could be seen. There were two small mountains in the general area of Bianchini G. and a mare ridge - all these were clearly seen. Caruso states that Bianchini G should normally be much more clearly seen than the other features mentioned and is the same size as Heraclides E. The Cameron 2006 catalog ID=305 and the weight=3. The ALPO/BAA weight=1.

nr Fra Mauro 1970 Aug 14 UT 05:00? Observed by Bell (Californina). "Bright blue-white flare (meteor?)(call for obs. at Fra Mauro at perigee because of moonquakes there -- therefore biased to tidal hypothesis. That was the original location given for the A1 moonquake site, but it is located elsewhere now. Ancill. data given for 1970)." NASA catalog weight=1. NASA catalog ID #1273. ALPO/BAA weight=1.
On 2017 Sep 02/03 UT 23:55-00:30 A.Anunziato (Parana, Argentina, 105 mm Maksutov-Cassegrain, x154, seeing 6/10, some interuption from clouds) observed a light spot SE of the centre of the floor of the crater, which came and went in visibility. There is a light spot here, but what was unusual was that the visibility decreased over time. ALPO/BAA weight=1.
Herodotus 1971 Jul 05 UT 03:48 Observed by Bartlett (Baltimore, MD, USA) described in the NASA catalog as: Pseudo-c.p. I= 4(albdeo) appeared to cast a distinct shadow. 1st time seen.

Aristarchus 1982 Nov 27 UT 20:13-01:00 J-H Robinson (Teighmouth, Devon, UK) found that the bands of Aristarchus were clearer in red than in blue light. North found that the sunlit part of the crater was very bright. M. Cook described the crater as a "kaleidoscope of colour. Foley observed UT 23:05-01:00 (Kent, UK, Antionadi III, Transparency Moderate) - Colouration Seen - Ref: BAA Lunar Section Circular. The Cameron 2006 catalog ID=190 and weight=5. The ALPO/BAA weight=3.

On 1997 Oct 13 at UT11:09-11:21 D. Rodway (Oamaru, South Island, New Zealand, 8.5" reflector, x270) saw a deep salmon-pink colouration in the south east corner interior of the crater Aristarchus. This colour was confirmed by the observers wife. By 11:21 UT the colour had faded completely. Rodway had been a lunar observer since 1958, using a wide range of instruments from 3 inch refractors to 12 inch reflectors and had observed a TLP in Gassendi back in 1966 (from L'ondon, UK), and so was an experienced observer. The ALPO/BAA weight=4.
Herodotus 2022 Nov 06 UT 00:05-00:38 A. Anunziato (Parna, Argentina - 105mm Meade EX 105, x154). Glimpsed an elongated light patch on the floor, slightly east of the centre of the floor. Observer was a bit uncertain if this was a genuine observation, or a biased observation – based upon the written account in the repeat illumination predictions. Detailed sketch made. Anyway, seeing detail on the floor of Herodotus was at the limit of his telescope. We shall therefore assign an ALPO/BAA weight of 1.
On 1982 Aug 01 at UT20:50 M. Mobberley (Suffolk, UK, 14" reflector, seeing III-IV) found that LaPlace A was significantly more prominent than usual - comparisons were made with photographs in books. The Cameron 2006 catalog ID=178 and weight=3. The ALPO/BAA weight=1.

On 1915 Jul 24 at UT 22:00? Barabashovihi (Russia) observed a TLP on the west limb: "When phi Strettsa (?) approached the edge but still separated, the star began to stretch in a belt 3X its own length & then instantly disappeared. Probably no significant atm. or vapors. (similar to other reports of fading occult. Gives limb as E. but that is in ast. convention)". The 1978 Cameon catalog ID= 357 and weight=2. The ALPO/BAA weight=1.

On 1960 Sep 04 at UT00:00? Miranova (Russia or Israel) observed a TLP at an unnamed lunar feature: "Spectral photom. of some lunar obj. in 4250, > 5000A bands. Spectral plates". Cameron suspects luminescence? The Cameron 1978 catalog ID=730 and weight=5. The ALPO/BAA weight=1.
Aristarchus 1982 Nov 28 UTC 23:35-23:55 Observed by Foley (Kent, UK, Antionadi III, Transparency Moderate) - Colouration Seen - Ref: BAA Lunar Section Circular. ALPO/BAA weight=2.
Aristarchus 1975 May 23 P.W. Foley (Wilmington, UK, 12" reflector, x200, x360, x624, atmospheric clarity good, seeing III from 20:15-22:30, but the clouded out at 22:30, and from 23:15-01:15 seeing was IV-V with poor transparency) observed (22:20-20:45 UT) variation in the SE corner of the Aristarchus, namely the usual dark bands were alternating light to dark, not in keeping with otyher crater features. This effect was not linked to atmospheric turbulence. Also projected image of bands beyond the crater W. wall were repeatedly noted. The observer broke away from observing at 20:45UT to make a telephonealert call. At 20:55UT they noted that the area between Vallis Schroteri and Herodotus seemed very light/bright, also the E. exterior of the crater wall of Herodotus. From 21:01-21:11 A slight blueness was seen to extend from the NE corner of Aristarchus, along the exterior rim, acrossand beyond Herodotus to the SW. A tgorough search was made of many bright areas, both near the terminator and to the E., but no blueness could be detected elsewhere. A slight orange hue was noted along the E. limb of theMoon (Spurious colour). From 21:18;22:30 Aristarchus seemed normal again, and likewise the head of Vallis Schoteri too. The observer was clouded out from 22:30-23:15and from 23:15-01:30 the seeing was so appaling that no colour or projection of the bands could be seen. A Moon Blink was used during the session, but no colour was detected in this? Another observer, R.W. Rose (Devon, UK) observed 21:20-21:30 but had IV seeing, and saw nothing unusual, but commented that if TLP wactivity had been taking place, then they would probably not have seen it. The ALPO/BAA weight=1.
On 1964 Jun 23 at UT 04:45-05:05 Bartlett (Baltimore, MD, USA, 5" reflector, x180, S=4-1 and T=3) observed a blue-violet glare on the north east rim and a strong violet tinge in the nimbus. The effect was absent 1 hour earlier. The Cameron 1978 catalog ID=821 and weight=4. The ALPO/BAA weight=2.
Aristarchus 2015 Mar 03 UT 23:58 Brendan Shaw (UK) saw a flash on the NW rim of Aristarchus on his computer screen - the camera was working in the near IR. Seeing was not very good at the time. Unfortunately this flash occurred in between imaging sessions. No other flashes seen, despite looking. The observer considerd the possibility that it might have been a cosmic ray detection, but cannot say for sure. The ALPO/BAA TLP weight=1.
Colour seen between Aristarchus and Herodotus by P. Moore and G. North. ALPO/BAA weight=3.
On 1977 Apr 02 at UT22:00-00:00 L. Fitton (Shaw, Lancashire, UK, 8.5" reflector, x200, Wratten 25 and 44A filters, seeing II-III, transparency, good) noticed in Aristarchus, blue to the north west (IAU?) internal wall, also blue observed in other small bright objects against dark backgrounds. Lunar rotational axis and optical normal related such that the normal runs NW-SE (IAU?) through these features. Observer deduced that the coliur was obviously spurious and no blink was seen in any feature. The blue disappeared as the lunar altitude increased and no blue seen by 00:00UT. This is a BAA lunar section observation. The ALPO/BAA weight=1.
On 1988 Apr 01 atUT01:15-03:20 H.Hill (Lancaster, UK, 10" reflector, x286) observed that east of Lichtenberg were ëxtensive rosy areas" around the northern edge of the lava sheet. Hill believes that it may have been the same effect as seen by Madler (Germany), Barcroft (USA) and Baum's (UK) 1951 observation. The colour was "ünmistakable" and nothing to do with the atmospheric spurious colour. Other features were checked. the cameron 2006 catalog ID=322 and the weight=3. THe ALPO/BAA weight=2.
On 1892 May 10th at 19:00UT? Pickering, based at Arequipa. Peru, using a 12" reflector, saw varitions in vapor col. Drawings were made. Time calculated from the given colongitude. Cameron 1978 catalog ID= and weight=3. ALPO/BAA weight=2.
On 1992 Jan 18 at UT 22:34-23:48 A.C. Cook (Frimley, UK, 8" reflector, seeing=III) was able to see 4 craterlets and two rays on the floor of Plato. This was suprising because Moore, using a larger telescope and magnification, was unable to see any detail here on 1991 Dec 12th at 02:10 - according to Cameron. The Cameron 2006 catalog ID=438 and the weight=2. The ALPO/BAA weight=1.

During an eclipse of the Moon the crater appeared normal until it emerged from the shadow. In the north east the dark floor was not its normal hue and two light areas appeared to join. The emerging patches became less and less bright, finally disappearing at 0345 UT when the crater returned to normal. Cameron 2006 catalog extension ID=10 and weight=2. ALPO/BAA weight=2.
1963Dec29/30 UT 22:00-03:00. Doherty (Small Thorne, UK) 8.5" reflector, x110, x200 & x274, S=8-8.5, T=8, Moon 57 deg in alt) and 3 others, using the same instrument, saw a bright purple- blue patch in Aristarchus. Other areas checked for colour and none sen elsewhere. Attempts were made to contact observers elsewhere but with no success. Sketch made and shows the patch covering the floor area of Aristarchus and extending out beyond the east rim. Patch was elliptical in shape and the semi-major diameter was approximately 2/3rds of the diameter of Aristarchus, or about 27 km. The event lasted 5 hours and gradually faded. NASA catalog weight=5 (very high quality)". ALPO/BAA weight=4.
1982 Mar 08 Daniell UT 22:49-22:57 P.Madej (Hudersfield, UK) - A colour and brightness anomaly was seen a TLP alert was put out. Cameron 2006 catalog extension weight=165 and weight=3. ALPO/BAA weight=2.

S.part of crater was brownish, (not on alert). Delano saw E.wall bright spot unusually bright, confirm, ?" NASA catalog weight=5. NASA catalog ID #947. ALPO/BAA weight=3.
On 1970 Aug 17 at UT 02:40 Pedler (England) noted that the shadow flowed around instead of over Plato. Wondered if shadow matched the gray of the crater. Within minutes the shadow line looked normal again. At 04:41UT Claudio Pamplona (Brazil) saw a pulsation in Plato during a lunar eclipse. He thought that this was due to falling temperatures. The Cameron 1978 catalog ID= 1274 and the weight=0. The ALPO/BAA weight=1.
On 1877 Aug 23/24 at UT 23:10-01:00 Airy, Pratt and Capron (Greenwich, England, France) observed during a lunar eclipse an unusual spectrum with strong absorption in yellow.

It's albedo=8, surroundings=7 (ALPO-LTP prog.)" NASA catalog weight=3. NASA catalog ID #1360. ALPO/BAA weight=2.
Aristarchus 1976 Nov 13 UT 05:25 Observed by Bartlett (Baltimore, MD, USA, 3" refractor, 54-200x, S=6, T=4) "Floor 8deg except S.=6deg which is also granulated & la pale yellow. Different aspect fr. other obs. at same col. Viol. in outer nimbus. Bright blue-viol. glare where viol. radiance was on 11th. SWBS still large & 9 deg bright." NASA catalog weight=4 (high). NASA catalog ID #1457.
On 1964 Jan 06 at 02:00? Markov and Khoshlova (Russia) observed anomalous IR radiation on the Moon. The Cameron 1978 catalog ID= and weight=5. The ALPO/BAA weight=3.
Aristarchus 1965 Nov 15 UTC 05:55-10:00 Observed by Hall, Johnson, Nordling (Pt. Tobacco, MD, USA, 16" reflector x400), Genatt (Greenbelt, MD, USA, 6" refractor, x50 & 20" reflector x400), Wagmann (Pittsburgh, PA, 30" refractor). "Color on c.p. detected with Trident MB, not seen vis. at Port Tobacco. Network alerted & 6 responded. 4 did not see anything unusual; 2 others did & saw red on c.p. in 6-in refr.. but not in 20-in refl. at 400x; other saw indistinctness. Port Tobacco obs. took 5 rolls of film in blue & red & neutral. Phenom. not detectable on them, but focus was poor. Blue image had most detail, whereas would expect red or neutral to. Phenom. still present at dawn in Moon Blink device." NASA catalog weight=5. NASA catalog ID #914. ALPO/BAA weight=4.
On 1983 Jan 05 at UT22:00 P. Madej (Huddersfield, UK) noticed some colour on Aristarchus. The Cameron 2006 catalog ID=195 and the weight= 2. The ALPO/BAA weight=1.
Aristarchus 1976 Nov 14 UT 06:09 Observed by Bartlett (Baltimore, MD, USA, 3" refractor, 54-200x, S=5-4, T=5) "Walls & floor 8deg except S.= 6deg, SWBS now smaller but still 9deg. S.floor still granulated & now yellow-brown. Strong viol. tint still on outer nimbus but now viol. radiance (gas?) again on ENE rim as on 11th, but not as on 13th" NASA catalog weight=4 (high). NASA catalog ID #1458.
