On 1939 Apr 22 at UT 18:00? Malakhov, Fillppova (Russia) observed in Aristarchus: "Intensive luminescence in ashen light". The cameron 1978 catalog ID=448 and weight=5. The ALPO/BAA weight=2.
On 1991 Dec 09/10 at UT 23:53-00:12 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 2010 Dec 09 at UT 17:00 A. Heath (Long Eaton, UK) whilst observing the Earthsine with 10x50 binoucluars, noticed some coloured bands on the night side. The NW sector of Eartshine, closest the limb was a normal dull brown, there was a whitish fringe on this going from the N to the SE, followed by a thicker bluish fringe. The rest of the Earthshine beyond, until reaching the illuminated crescent was black. The two coloured fringes curved slightly. Local temperature 38F and some broken cloud present. Thickening cloud prevented further observations. The observer suspects that it could have been caused by the weather conditions, but could also have been due to a cataract starting to form in his observing eye. This is unlikely to be a TLP due to the above observer suggested reasons, and anyway it would have to have been an unbelievably large phenomena to cover such a large part of the Moon. However it is worth checking to see if anybody else was observing at the time. ALPO/BAA weight=0.
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 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.
In 2005Apr14 at UT18:32.5 +/-2.5 min A.Brosio (Rosarno (Reggio Calabria, Italy, Latitude: 38d 29' N, Longitude: 15d 58'E, 152mm reflector, x75) observed a small square form in Earthshine near Archimedes. This is a UAI observation.
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.
Proclus 1983 Jan 19 UT 20:36-21:00 Observed by Cook (Frimley, UK, Seeing III, Transparency, Moderate) "Colouration seen". BAA Lunar Section Report. ALPO/BAA weight=2.
Leibnitz Mountains 1948 Apr 14 UT 20:00? Observed by Wilkins (Kent, England, 12.5" reflector) " S.cusp prolonged -- detached peaks -- starlike pts. connected by fine filaments brighter than earthshine. (Barcroft, Haas, Vaughan, Moore & Firsoff also have seen similar phenom.)(just sunlight catching high peaks?)." NASA catalog weight=2. NASA catalog ID #502. ALPO/BAA weight=1.
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. Area was as large as Menelaus & had just come into sunlight. The dome just W.(IAU) of Menelaus?)." NASA catalog weight=3. NASA catalog ID #1065. ALPO/BAA weight=3.
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.
On 1984 Jun 05 at UT20:00 Marshall (Covington, UK) saw an unusual darkening on the floor of Proclus and irregular shape. The Cameron 2006 catalog ID=243 and the weight=2. The ALPO/BAA weight=1.
Webb (England, using a fluid achromat) saw brilliant minute spots and streaks in Mare Crisium dotting its surface. This was seen near first quarter. Cameron states that Schroter, Betr?, Madler, Slack and Ingall had all seen it this way at times. Cameron 1978 catalog iD=111 and weight=3. ALPO/BAA weight=2.
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.
Plato 1948 Apr 15 UT 20:00? Observed by Thorton (Northwitch, England, 9" reflector) "Brilliant orange-yellow flash 1 km inside E. rim (similar to earlier #500 LTP flash in the dark)" NASA catalog weight=3 (average). NASA catalog ID #504.
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.
Cassini 1972 Jan 23 UT 16:55-17:15 P.Radford (Harlow, UK, 11.5cm reflector) saw a large red flash followed by several weaker red flashes, situated on the 32,335 foot spot elevation just above the Cassini area. The ALPO/BAA weight=2.
"Eudoxus" 1877 Feb 20 UTC 21:30-22:30 Observed by Trouvelot (Meudon, France, 13" refractor?) "Fine line of light like a luminous cable, drawn W. to E. across crater". NASA catalog weight=1. NASA catalog ID #185. ALPO/BAA weight=1.
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.
Mobberley and Foley note that Aristarchus was very prominent in Earhshine. Little other detail seen in Earthshine other than the limb. The Cameron 2006 extension catalog then says: "Confirm moving side to side. Saw bright blue spot in center" however it is unclear whether this refers to Aristarchus, or Torricelli-B - the latter was also undergoing a TLP at this time. Cameron 2006 extension catalog ID=267 and weight=5 (confirmed?).
On 1985 Apr 27 UT 22:00 M. Mobberley (Suffolk, UK) could not see much detail in Earthshine (apart from Aristarchus), except that there was a brightness on the western limb of the Moon. The Cameron 2006 catalog ID=267 and the weight=5. The ALPO/BAA weight=1.
2004 Nov 20 UT 01:43:36 R. Spellman (120mm F8.3 refractor at prime focus, PC23C CCTV camera, via a DVD recorder) recorded a flash of light. The ALPO/BAA weight=1.
A dome-like feature, sketched by Herring and confirmed in a photograph by Larson. This had not been seen before by Herring in hundreds of hours of observing. No other reports of this. The photograph was taken at 02:50h. Cameron 1978 catalog ID=878 and weight=5. ALPO/BAA weight=3.
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.
Alphonsus 1968 Apr 06 UTC 20:30-21:15 Observed by Wise (Slough, England, 17" reflector x190, x350, S=E" Suspected glow inside W.(ast?) wall at 2038" NASA catalog weight=1 (very low). NASA catalog ID #1066.
Plato 1968 Apr 06 UTC 20:30-21:15 Observed by Wise (Slough, England, 17" reflector x190, x350, S=E" Dark patches in Plato were prominent" NASA catalog weight=1 (very low). NASA catalog ID #1066.
Straight Wall 1968 Apr 06 UTC 20:30-21:15 Observed by Wise (Slough, England), 17" reflector x190, x350, S=E "A shadow from N. end of Straight Wall going toward Birt. Drawing". NASA Catalalog weight=1 (very low). NASA catalog ID #1066.
On 1931 Mar 27 R.Barker (observing from Cheshunt, UK, 12.5" reflector) found that the central mountain in the brilliant ray crater Tycho was a curious shade of grey. This was despite the interior of Tycho being fully in shadow. Cameron 1978 catalog ID=400 and weight=3. ALPO/BAA weight=3.
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.
Proclus 1972 Jul 19 UT 21:24-21:30 observed by S.Westmoorland (Cropwell-Bishop, UK, 15cm reflector, x48 & x96, image dull but steady) observed a brilliant spot in the NE (IAU?) wall which lasted for about 90 seconds. After fading it was replaced by pulsations for a further 2 minutes. Clouds prevented further observations. ALPO/BAA weight=1.
1996 Apr 27 UTC 02:26-03:14 Observed by Spellman (Los Angeles, CA, USA) " 02:26 U.T. Sunrise on Tycho 3/4 of the crater was in shadow, topmost section of the central peak was in sunlight. In white light brightness of the central peak rivaled the brightness of the Eastern (sunlit) wall. No change was detected in red light, however in blue light definite strong darkening was observed. Blink obtained when viewing thru 25A and 38 filters. At 2:52 U.T. in the poor to fair seeing the apparent size of the central peak in white and red light was the same, in blue light the central peak in white and red light was the same, in blue light the central peak size shrank to 1/2 white and red size (and brightness). Also appearing sharper. Comparison was made also with the central peak of Alphonsus, no changes were observed. The significant part of the observation was the relative brightness of the central peak to the sunlit rim in white and red light, they appeared almost identical with the crater rim, being just slightly brighter. In blue light the brightness of the central peak was reduced by at least half while the rim brightness was not, (relative to one another). I strongly believe that this was a real event. The shadow filled portion of Tycho was examined for any abnormalities but none were observed. Observations were ended shortly after 3:14 U.T. due to clouds. I also conducted about 20 Moon blink observations during this observing run and got the same strong reaction each time." ALPO/BAA weight=3.
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.
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.
Piton 1958 Sep 23 UT 00:00? Observed by Moore? (UK?) "Enveloped in an obscuring cloud-like mist" NASA catalog ID 697. NASA catalog weight=2. 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.
A region of the Mare Imbrium was extremely bright, giving a reading of 8 out of 10 on the Elger scale. Cameron notes that from photos of the Full Moon, the area appears to normally be the brightness of Archimedes floor i.e. 3.5 out of 10 on the Elger scale. Atmospheric seeing was excellent and the observer could see a lot of fine detail with their 2.4" and 3" refractors. Cameron 2006 catalog extension ID=62 and weight=3.
Sinus Iridum 1996 Apr 28 UT 20:00 Observed by Brook (Plymouth, UK, 60mm refractor, x112, seeing III, slight breeze, twilight) "dark shaded area on floor ~1/4 diameter of Sinus Iridum on western interior by rim" BAA Lunar Section Observation. ALPO/BAA weight=1.
Ross D 1965 Dec 04 UT 04:25 Observed by Cross (Whittier, CA, USA, 19" reflector, x155, seeing 4+) "Obscuration of part of the rim, also bright area 7-10km diam. Not seen on following nite." NASA catalog weight=4 (good). NASA catalog ID #917. ALPO/BAA weight=3
Bulialdus 1979 Aug 03 UT 21:36-21:48 Observed by Cook (Frimley, UK, seeing III, Moonblink device) "Bullialdus eastern side of the crater looked brighter in red i.e. rim and exterior, extending to the south slightly and this reddish areas was slightly hazy. 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."
W. of Mare Humorum (50W, 25S) UTC 00:00? Observed by Mac Farline (England?) "Bright Point" NASA catalog weight=2 (low). NASA catalog ID 719.
Plato and Plato A 1972 Jan 26 UT 18:25-18:55 Observed by Watkons and Hunt (England, 4.5" reflector x150, x225, and a 2.75" refractor) "Misty patch over A, & a misty brightness over SW wall of Plato. Hunt saw nothing unusual." NASA catalog weight=2 (low). NASA catalog ID #1321.
In 1820 Oct 17 at UT 20:00 an unkown observer reported in Mare Imbrium, south of Sinus Iridum (30W, 40N) some brilliant spots. The Cameron 1978 catalog ID=80 and weight=1. The ALPO/BAA weight=1.
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.
Aristarchus 1971 Sep 01 UT 20:45-21:05 Observed by Neville, Cunnington (Nottingham, UK, 4" refractor x180, altitude, low) "Saw a bright glow, especially in E. wall (Confirm. but not indep.?)" NASA catalog weight=3. NASA catalog ID #1310. 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. (Rawlings dubious). Moore, with blink device saw none at 0020-0140h. No LTP in Gass., Ptol. or Aris. 5th or 6th.". NASA catalog weight=1. NASA catalog ID #1093. ALPO/BAA weight=1.
On 1964 Jun 21 at UT 21:18 Lipskii and Pospergelis (Shternberg State Ast. Institute, AZI-2" reflector (Cass.) observed Aristarchus: "Polarization meas. with electron polarimeter. Plane of polariz. rotated 2deg fr. the adjacent areas. They interpret it as some scattering medium over the crater. (Source gave date as 6/31/64, misprint =21st?)". The Cameron 1978 catalog ID=820 and weight=5. The ALPO/BAA weight=4.
Observed by Haas (Las Cruces, NM, USA) "Temporary greyness seen in interior shadow." ALPO/BAA weight=3.
On 2003 May 13 at UT06:40-07:26 W. Haas (Las Cruces, NM, USA, 12.5" reflector, x321 and x202, S=2, T=3.5) suspected (06:40-06:55UT) that he saw an oval bright feature (intensity 5.5) near the centre of the floor of Herodotus crater indenting into the shadow - however the seeing was none too good, so it is more of a suspicion than a definite sighting. At 07:14-07:26UT he re-examined the region (x202 and x321, S=1-2 and T= 3.5) and had better glimpses that conformed his initial suspicions of there being an oval indentation bright spot (now intensity 6) into the shadow in the centre of the floor. Of course Herodotus does not have a central peak! There was also a very bright spot on the NW> sunlit rim of Herodotus crater. The ALPO/BAA weight=2.
On 1965 May 12 at UT 22:20 H. Miles (UK) found a possible obscuration in Bailly crater. Most of the region was as sharp as normal, but the central area was greyish and blurred. Although the observer concerned considered themselves a non-experienced observer, another BAA Lunar Section observer saw the same effect. ALPO/BAA weight=2.
Aristarchus Area 2004 Nov 22 UT 04:58-05:49 Observed by Gray (Winemucca, NV, USA, 152mm f/9 refractor, seeing 4-5, trasparency 4-5, x114, x228) "Blinked Herodotus with Wratten filters Blue 38A and Red 25. The illuminated west crater wall stood out brilliantly in blue light, much more so than in white light. This was true also of Aristarchus. Red light did not increase contrasts in Herodotus any more than they were in white light. Shadows in Herodotus appeared as black as the night west of the terminator and remained that way throughout the observing period. No TLP seen in Herodotus tonight. A possible TLP was seen to the west of Herodotus near the terminus of Schroters Valley. It was noted at the beginning of the observing period that there were four very bright spots of light, one near the end of Schroters Valley, the other three grouped together a little farther north. Although not far from the terminator they were definitely east of it. It was noted that all of them nearly vanished in the Blue 38A filter while Aristarchus and the rim of Herodotus gleamed brilliantly. At 5:19UT it was noted that the most brilliant of the four lights, the one near the terminus of Schroters Valley, had faded almost to invisibility in white light. When first seen it had been brighter than Aristarchus. It remained very dim after this through the remainder of the observing period, and was unchanged at 7:35-7:49UT when I again examined the area. The other three bright spots remained brilliant and unchanged."
Blanco, J. Vidal, of Gijon, Spain (3" refractor x72) noticed an unfamiliar very bright center near to Encke. Cameron suspects that this was Encke B crater on the basis that it is a prominent small crater near to Encke. Cameron 2006 catalog extension ID=410 and weight=2. ALPO/BAA weight=1.
On 1995 October 6 at UT 21:30 R. Lena (Rome, Italy - a UAI observer, 11.4cm reflector) saw 4 or 5 flashes from Herodotus crater. Light intensities (mag?) ranged from 9 to 8 and they were brighter through a red filter. There is no 2006 Cameron catalog entry for this observation - it has come from the UAI web site. The ALPO/BAA weight=3.
Mersenius 1975 Jun 21 UT 21:50-22:45 Observed by McConnell (Northern Ireland, 6" reflector) Moore? (Sussex, Enland, 15" reflector, 5" refractor, S=F), Reading (Rushden, England, ? 14" reflector) and Foley (Kent, England, 12" reflector, S=P) "McConnell saw an obscur. starting at 2150h which disappeared at 2245h. Moore(?) alreted, saw no anomaly in 15 in refl. & 5-in refr. under fair conditions from 2209-2228h. Reading reported neg. fr. 2250-2345h (after phenom.). Foley reported color in it but also a crater to S. of it & Aris., prob. due to seeing conditions." NASA catalog weight=5. NASA catalog ID#1408. ALPO/BAA weight=3.
Aristarchus-Herodotus 1971 Sep 02 UTC 20:00 Observed by Ayeau (Paris, France, 12" reflector, x100) "Brownish-red or maroon seen on Aris. W.wall ridge to Herod. on S.wall of Herodotus" NASA catalog weight=2. NASA catalog ID #1311. ALPO/BAA weight=2.
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 1995 Oct 06/07 at UT 22:45-00:00 P. Mirteto (a UAI observer, RI, Italy, 20cm reflector) observed some brightness changes in Herodotus. Please note that this description is a summary of the material on the UAI web site. The ALPO/BAA weight=2.
1954 Aug 11 observed by Firsoff (Somerset, UK, 6.5" reflector, x200) "Brilliant in red filter, variable)" NASA catalog weight=4. NASA catalog ID #570. ALPO/BAA weight=3.
On 1995 Oct 06/07 at UT 23:05-00:00 P. Mirteto (a UAI observer, RI, Italy, 20cm reflector) observed some brightness changes in Prinz. Please note that this description is a summary of the material on the UAI web site. The ALPO/BAA weight=2.
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.
Amery (Reading, England) saw blue in Aristarchus but a photograph did not show the colour. Foley thinks this was spurious colour. Cameron 2006 extension catalog ID=27. ALPO/BAA weight=1.
Promotorium Laplace: 1978 Apr 20 UT19:30-22:35 Peter Foley observed a tiny yellow-brown region close the tip of the cape, north east of the precipitous west edge, in the face of the north facing slope. The area concerned was diffuse and varied in density despite the surroundings not varying. Foley notcied no colour elsewhere on the Moon, though Amery thought that he saw some in Aristarchus, but Foley thinks this was spurious. Cameron 2006 catalog extension ID=27 and weight=5. ALPO/BAA weight=3.

Aristarchus. 2024 Mar 23 UT 22:08. G.Vega (Argentina, Oro Verde - 20cm f/5 Newtonian on an EQ5 Goto mount - two colour cameras used: a Player One Ceres C & a Nikon D5100). Colour images show a region of blueness from the W. rim of Aristarchus and the NE of Herodotus (maybe also on the inner SE rim of Herodotus?) i.e. generally SE of the Cobra's Head. Blue colour is usually present on the rim of Aristarchus and to the north - but I don't recall seeing such strong blue colouration in this region before? No other craters exhibit this blue colour. As the colour is present in two images, taken with different cameras it looks genuine. Two other colour images, at lower resolution, were taken from Oro Verde, by W.Elias, at 23:06 and 23:18, but neither of these exhibit this blue colour - but that maybe a resolution issue? ALPO/BAA weight=3.0
On 1973 Dec 8 UT18:15-18:20 R.Billington (UK, 2" refractor) reported that ristarchus was orange. However 15 minutes earlier, another observer, Livesey made a sketch and did not report any colour. ALPO/BAA weight=1.

Herodotus 1972 Jul 27 UT 2250-2350 M.Brown (Hutington, UK) thought that he saw a pseudo peak in the centre of Herodotus. He could not decide if it was real or an optical illusion. ALPO/BAA weight=1.
Aristarchus 1970 Feb 23 UTC 07:00? Observed by Thomas & Stump (Corralitos Observatory, Organ PAss, NM, USA, 24" refletor+Moon Blink) "Bluring around crater -- vis. in monitor, but not photographed due to clouds." NASA catalog weight=4 (good). NASA catalog ID #1235.
On 1990 Aug 08 at OT 07:47-09:00 UT D. Louderback (South Bend, WA, USA, 3" refractor, x173) "(SS) Piton's all pts were << but nearby plain was normal. Ridges at 5.3 at B, C, D but 3 alb at B, C, D (norm = 7) but bearby plain was normal. At A 3, was hazy but ill defined. Parts of mt brightened but others didn't. Times between brightening were 6-8s. Similar to seeing fluctuations. In red mt stayed dull & steady. In blue it blinked." - this is a direct quote from the Cameron 2006 catalog because it is very difficult to summarize. Louderback comments that the TLP was still going on at 09:00UT. The Cameron 2006 catalog ID=406 and the weight=4. The ALPO/BAA weight=3.
On 1990 Aug 08 at UT 07:47-09:00 D. Darling (Sun Praire, WI, USA, 3" refractor, x173) reported the following TLP in Promontorium Agarum (Cape Agarum): "W flank of CA >>, even> Proc. interior." The cameron 2006 catalog ID=406 and the weight=4. The ALPO/BAA weight=3.

On 1964 Feb 02 at UT08:30-09:40 G.Reneau and B.Crowe (2.4" refractor, x90)observed Ross D to be double. This was during a time when observers were looking for a Ranger crash plume. The Cameron 1978 catalog ID=799 and weight=1. The ALPO/BAA weight=1.
Something resembling a cigar shaped shiny object seen on S rim - hanging over a smaller crater. It looked like a bright aluminum can in the sun & cast a shadow onto the rim. The length was 8-10 miles long x 1 mile wide at the central point. It appeared tapered to points at both ends. Observer studied it for several hours. S term. ~60-70miles away. Apparently not related to topog. Alt. 8deg. Cameron 2006 Extension catalog weight=3. ALPO/BAA catalog weight=1.
On 1983 May 31 at UT03:45-04:30 K. Marshall (Medellin, Columbia) noted that the whole area of Aristarchus, Herodotus, and Schroter's valley was both blurred and violet. There was hardly any detail seen inside the crater. Herodotus could hardly be seen either and Schroter's valley was totally unrecognizable. A sketch was supplied. The Cameron 2006 catalog ID=223 and the weight=3.
Alphonsus 1972 Jul 30 UT 00:30-03:30 Observed by Morgan (UK using a reflector) "Orange glow, brighter this nite than last nite. Following nites were cloudy. Aristarchus and Gassendi were negative." NASA catalog weight=3. NASA catalog ID #1338. ALPO/BAA weight=3.
Observed by Bartlett (Baltimire, MD, USA, 5" reflector, x150) "N. half of crater hazy & ill-defined". S=5, T=4. NASA catalog weight=4 (good). NASA catalog ID 571.
On 1979 Aug 12 at UT07:00-10:35 D. Darling and wife (Sun Prarie, WI, USA, 12.5" reflector, x342, photos, S=9/10) observed a cigar shaped protruberance in Romer crater that cast a 32km long shadow, nestled in a valley rille next to Romer. This was a confirmed observation. The effect persisted intil sunset. The top of the object and two points on the crater rim were reflecting the Sun's rays. "Top of obj. & 2 pts on crater rim reflected suns rays. It was as high as the crater rim whereas the rill wall was not. Took photos. he has studied this area and never saw such a phenom before. Photos did not show it". The Cameron 1978 catalog ID=65 and weight=5. The ALPO/BAA weight=2.
On 1997 Jul 25/26 at UT 23:00-00:00 S. Fox (Dundee Tayside, Scotland, UK, 15cm f/5 reflector with x4 Barlow). A series of photographs were taken that show a glow just beyond the terminator, near to Callipus crater. Almost certainly this is lens flare from the Barlow lens. The ALPO/BAA weight=1.
Observations made with a variable polarizer (akin to a crater extinction device) to measure brighness with red and blue filters. Some variability in brightness noted. With the Kodak Wratten 25 and 38A filters there was little or no increase in contrast with the red filter, but with the blue filter there was a great increase in contrast of the brighter areas of the crater - the crater floor and patches of lighter material, especially at the north end. The remaining areas were supressed with the Blue 38A. ALPO/BAA weight=3.
On 1980 Jul 05 at 03:20UT P.Moore (Selsey, UK, 12?" reflector) found Aristarchus to be "Very brilliant indeed". Cameron 2006 TLP catalog ID=100 and weight=3. ALPO/BAA weight=2.
Alphonsus 1956 Oct 26 UT 12:54 Observed by Alter (Mt Wilson, CA, USA, 60" reflector, S=E) "Photog. thru UV & IR filters. Obscur. of E. 1/2 of floor evident in blue plates -- KodakII-O plate no filter. 2m later Kodak I-N. One pair of plates best he'd ever seen. Similar obscuration seen 2X on Linne (this started Kozyrev on his spectrographic program.)." NASA catalog weight=5 (very high). NASA catalog ID #653.
Aristarchus 1955 Jul 13 UTC 02:50 Observed by Firsoff (Somerset, England) "Brilliant in blue & green filters. Didn't seem to be as clear as other craters." NASA catalog weight=4 (good). NASA catalog ID #598.
Spitzenberg Mountains 1980 Jul 06 UT 02:05-02:26 Observed by Madj (Newsome, Huddersfield, UK, 70mm OG, Seeing started as I and ended up as IV) "Obscuration seen near Spitzenberg Mountains" BAA Lunar Section Report.
Copernicus 1996 Sep 06 UT 01:45 Observed by C Brook (Plymouth, UK, 60mm refractor x28, x112, transparency, not good) "Shadows of central mountains could not be seen although the shadows on the crater ramparts were visible" BAA Lunar Section report. ALPO/BAA weight=2.
Herodotus 1955 Jul 15 UT 03:50 Observer by Firsoff (Somerset, England, 6.5" reflector?) "Shadow from apparent c.p. (Orbiter photos don't show it but Apollo 16 oblique shows a very low hill or hills, but slope is < 2.5deg" NASA catalog weight=4 (high). NASA catalog ID #599. ALPO/BAA weight=3.
On 1987 Oct 17 at UT17:00-18:00 (in daylight) J. Moeller (Kerkville, NY, USA, 6" reflector, x80-x135) observed that Aristarchus had a long trench-like feature going off to the north west limb. On the 18th this feature was more cloud like, "bright white and opaque. (Trench = Schrotes Valley? Similar to 10/13/67)". The Cameron 2006 catalof ID=311 and the weight=1. The ALPO/BAA weight=1.
On 1969 Feb 12 at UT 12:00 Taboada (Mexico, seeing=excellent) found that the Aristarchus region had the same characteristics as the previous days, perhaps a little darker colour brown, but more remarkable. He used red, blue and green filters and a difference in colour was noticed in and out of the region. Cameron suspects that permanent colour was being seen? The cameron 1978 catalog ID=1116 and weight=3. The ALPO/BAA weigh=2.
On 1983 Feb 08 at 06:30UT Toricelli B was observed by P.W. Foley (Kent, UK, 12" reflector) to be visible in Earthshine as a luminous patch. This was rather odd because it is only a small crater and not normally bright. The Cameron 2006 catalog extension ID=201 and the weight=2. The ALPO/BAA weight=2.
