He had seen lights before but never so strong. The Cameron 1978 catalog ID=151 and he weight=4. 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.

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 1981 Feb 10 at UT21:46-21:49 P. Madej (Huddersfield, UK) found a 2nd mag star-like point on the north east wall of Aristarchus crater. M. Price (Camberley, UK) at 21:46 and 21:49. North (UK) detected flashes from the central peak. Foley saw Aristarchus as a "translucent glow". Moore, Pedler and Ratcliff could not find Aristarchus. Earlier though Amery (Reading, UK) had found Aristarchus to be sharply defined. Cameron 2006 catalog ID=122 and weight=5. ALPO/BAA weight=3.

On 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.
Limb North? 1881 Jul 04 UT 00:30 Observed by Several observers (Lebanon, CT, USA, naked eye, alt @ 10 deg) "2 pyramidal protruberances on upper limb (dark?). Points were darker than rest of moon's face then slowly faded away (atm ? moon very low)" NASA catalog weight=? NASA catalog ID #223.

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.

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 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.
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.
On 1982 Jul 01 at UT 02:23-02:58 Robotham (Springfield, ON, Canada, seeing=II) found that the west rim of Pytheas crater was a very bright yellow-white, indeed brighter than Proclus. At lower magnifications, Pytheas was one of the brightest spots on the Moon. The Cameron 2006 catalog ID=173 and weight=2. ALPO/BAA weight=2.
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.
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.
Sinus Iridum 1996 Apr 28 UT 22:00 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.
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 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.
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 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.
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 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.
On 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. He detected a tens of km scale elongated cloud after the impact over a duration of 9.5 minutes. 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=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.
Plato 1981 Jun 14 UT 21:58 Observed by Foley (Kent, England, 11.75" Newtonian, Seeing III, Transparency Good) "Obscuration Seen" BAA Lunar Section Observation. ALPO/BAA weight=2.
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.

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.
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.
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.
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 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.
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 1988 Sep 23 at 19:40-19:55 & 20:36-20:41 G. North (760mm Coude Rrefractor, x250, Royal Grenwwich Observatory, Herstmonceux, UK, seeing V, Transparency: Fair). 19:40-19:55 image very unsteady. All seems normal in other crtaters with the exception of Arcimedes. Much of the rim seems indistinct apart from a 1/4 length of the west rim. Strongly suspected that this was due to a combination of seeing and illumination. UT 20:02-20:06 - checked the area with a lower magnification 10" Astrographic Refractor - the crater seems more normal, so suggesting that the theory was correct. 20:36-20:41 returned to the 30" reflector, and the crater appeared similar to the start of the session. This is almost certainly not a TLP, but it would be helpful to have some images or sketches to check this theory out. Weight=1.
On 1985 May 02 at UT 20:20-20:38 J.D. Cook (Frimley, UK) noted at 20:20 found the south rim (and just outside) to be blurred in appearence and there was also a hazy shadow inside the crater. M.C. Cook found a "break in clarity in break on S wall". Miles (UK) also found the south wall blurred in appearance and Foley (Kent, UK) noted that the area was featureless and the 2 craters positions at 1 o'clock high up on the inner wall were obscured", although just north of these was sharp detail. Foley also recorded that the shadow on the east wall was opaque"and that thye inside of Aristarchus was slate/blue in colour and dull, however by 20:28 the crater had brightened by 0.4 steps on Foley's CED device and the missing craterlets were visible again. Jean (Canada, 4" refractor) observed a rose colour intermittently (UT 1948- 20:58) - however Cameron suspects that this is chromatic aberation. The Cameron 2006 catalog ID=269 and the weight=5. The ALPO/BAA weight=3.
On 1987 Mar 13 at UT02:00-03:00 De Groof (Belgium, 8" reflector x150, seeing=clear) noted that the north west part of Aristarchus had a blood red shimmering filling the whole crater. A video by Mobberley some 18 hours later, shows variation in Aristarchus. Cameron 2006 catalog ID= 301 and weight=5. ALPO/BAA weight=3.
On 1977 May 30 at 21:04-02:13UT J.H.-Robinson noted a loss of detail inside Gassendi, however he did not regard this as a TLP. The effect was also seen by P.W. Foley. Cameron 2006 extension catalog TLP ID=16 and weight=0 ALPO/BAA weight=1.
On 1964 Jan 27 at 21:00? Scarfe (UK) obtained spactra showing luminescence? The Cameron 1978 catalog ID=797 and weight=5. The ALPO/BAA weight=3.
Manilius 1968 Nov 04 UT 00:15-00:30 Observed by Jean et al. (Montreal, Canada, 4" refractor, 6" reflector) "Extremeley bright flash on Men. & Man. each." NASA catalog weight=2 (low). NASA catalog ID #1101.
Menelaus 1968 Nov 04 UT 00:15-00:30 Observed by Jean et al. (Montreal, Canada, 4" refractor, 6" reflector) "Extremeley bright flash on Men. & Man. each." NASA catalog weight=2 (low). NASA catalog ID #1101.
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.
Alphonsus 1966 May 03 UTC 21:30 Observed by Smith (England, 10" reflector) and Corralitos Observatory (Organ Pass, NM, USA, 24" reflector, Moonblink) "Reddish patches. Not confirmed by Corralitos MB (but in their report they give the feature as Gassendi)." NASA catalog weight=2. NASA catalog ID #936. ALPO/BAA weight=1.
