On 1988 Apr 18 at UT 19:00 R. Manske (Madison, WI, USA) observed that Aristarchus? was glowing in Earthshine. Weier (Madison, WI, USA) detected it easily in 7x50 binouculars. Spain (Fairfield, KY, USA) though detected no TLP, nor could he see Aristarchus. The Cameron 2006 catalog ID=324 and the weight=0. The ALPO/BAA weight=1.
On 1970 May 08 at UT 23:00-23:30 Celis (Quilpue, Chile, 3" refractor, x60, atmosphere turbulent) observed in the Aristarchus region a clear line(?) and several star-like points. Cameron suspects atmospheric effects due to low altitude and turbulence? The Cameron 1978 catalog ID=1259 and weight=1. The ALPO/BAA weight=1.
On 1989 Apr 09 at 02:13 was seen to be not very bright in binoculars, despite visibility of Earthshine in general as being exceptional. Darling confirmed this at 02:31UT, though it was quite bright in a 17" reflector,but Herodotus could barely be seen. Weier claimed to be able to see Aristarchus with the naked eye. At 02:08 the brightness was found to be 5.0 for several measurments. The observing team ware from the Maddison Asgtronomical Society, WI, USA. The Cameron 2006 catalog ID=359b and he weight=3. The ALPO/BAA weight=2.
On 1990 Apr 28 at UT 00:00-00:30 F. Graham (Marshall TWP, OH, USA, 6" reflector) during a failed attempt to observe the occultation of X6493 that was thwarted by clouds, noticed that Gassendi was "Gass,>>,>Aris or anything else". The crater had a "milky lustre". It is possible that another occultation observing group may have a video of the Earthshine at this time. Darling (Sun prairem WI, USA, 20x50 binoculars) could not see Earthsine, though the sky was bright at the time. The Cameron 2006 catalog ID=402 and the weight=0. The ALPO/BAA weight=1.

Boussingalt 1860 Apr 24 UT 20:00? Observed by Schmidt (Athens, Greece, 7" refractor) "Noted weak glows on the crater he tho't prob. due to wall reflections on floor" NASA catalog weight=0 (very unlikely to be a TLP). NASA catalog ID #132. ALPO/BAA weight=1.
Bright spot (in dark part of Moon - confirmation of Arkhipov?). Cameron 1978 catalog weight=5 and Cameron 1978 catalog serial No. 418,
On 1980 Nov 11 at UT17:35-18:32 G. Blair (Weir, Scotland, UK) at 17:35UT immediately noted that the Earthsine was extremeley bright. All large detail easily seen on unilluminated disk. 17:38UT a definite pale reddish brown tinge enveloped the Aristarchus area. 17:39 seemed to be getting larger and more intense west (IAU) side. Attempted to contact other observers. 17:40UT Aristarchus still had a bright central peak. 17:50UT fading a little from the west (IAU). 18:00UT slight revival in brightness. 18:15UT effect still visible when Aristarchus set behind a high western horizon. The two sketches supplied show the illuminated region around the crater with extension to the west (IAU). P. Foley (Kent) found thatAristarchus was bright enough in Earthshine to be seen with the naked eye. Telescope in operation at 18:00UT and the entire Aristarchus region was bathed in violet/rose colour with what appeared to be a strong ray extending to the west (IAU). Detail could be clearly seen inside Aristarchus crater such as the central zone, west and north wall and rim in relief from point southeat to northwest. CED measure 0.8 (white), 0.9 (blue), 0.2 (red). No other reading in Earthshine gave a measure in red. Observation ceased by 18:32UT as the Moon was very low. ALPO/BAA weight=3.
In 1855 Jun 20 at UT 21:00 T.W. Webb (England) observed a trace of twilight (Cameron says also seen by Gruithuisen, Henry and others at times). Webb gives a low weight to his own observation, saying "for want of better optical means". The Cameron 1978 catalog ID=130 and weight=1. The ALPO/BAA weight=1.
On 2012 Mar 28 at UT 20:45-20:50 Two unknown Italian observers, reported on an on-line formum that they had independently seen a distinct glow with a comma/drop shape. One of them moved the Moon and the glow moved with the Moon. It is uncertain how experienced the observers where. A chart was provided which shows the lcoation of the glow in the western side of Mare Imbrium. It is just possible that this was Aristarchus in Earthshine, though that is very slightly further west and south than the observers reported. ALPO/BAA weight=1.
On 2012 Mar 28 P. Grego (Cornwall, UK, seeing II, 100mm refractor, x132) observed a patch of light just inside the NW rim of Menelaus on the shadowed wall or floor. Computer visulaiztions of the illumination conditions using a digital elevation model failed to produce this effect. ALPO/BAA weight=3.
Cepheus A 2000 Oct 04 UTC 08:15-08:50 Observer: Maurice Collins (New Zealand, 90cm ETX) - observer noted that crater was extremely bright - wasn't sure if this was normal and at the time rated it as the brightest (contrasty?) crater that he had ever seen on the Moon. Many years later he suspected that he may have mis-identified the crater. This still leaves us with thr problem as to why a crater should be so bright in this region, and if so, which one? ALPO/BAA weight=1.
Pitiscus 1981 Sep 05 UT ??:?? but assumed to be AM? which would make it 00:00-03:00UTC. Observed by Slayton (Fort Lauderdale, Florida, USA, 8" reflector, ASA 64EK7 f/170, Kodak Kodachrome) photographed a bright glow in the crater that appeared to move. Observer also reported seeing it visually noting that it looked gray with a tinge of red. For further information see p266 of Sky & Telescope (1991, March). Note that Cameron gives the date and UT at 1981 Sep 06 UT 01:00-01:30, or one day later. I will use this date and time from now on. The Cameron 2006 catalog ID=152 and weight=5. The ALPO/BAA weight=3.
In 1982 Sep 24 at 22:45-23:40 K. Marshall (Medellin, Columbia) saw in Theophilus an obscuration on the south west wall close to Cyrillus and furthermore it had a red / mauve colouration (seen best in a 12mm Ortho eyepiece). Through a Wratten 15 yellow filter the region was quite bright. At23:40UT the obscuration faded. There was plenty of detail in the region between Theophilus and Cyrils. The Cameron 2006 catalog ID= 184 and the weight=3. The ALPO/BAA weight=3.
On 1915 Apr 21 at UT 1800? Houdard (France) noticed a special occurrence south of Posidonius which he took as evidence of water vapor. The Cameron 1978 catalog ID=351 and weight=3. The ALPO/BAA weight=2.
Proclus 1970 Jul 11 UT 20:35-20:45 Observed by Dean, Jamieson, Sparks (Ruislip, ------, England, 6" relector x156) "Dean saw something in Proclus, alerted Jamieson who saw nothing unusual at 2043h, but tho't Secchi was quite bright. At 2035 Sparks saw Proc. fluctuate. Red & blue filters showed some reduction in brightness. E. edge showed darkening, but not as dark as in shadows. 10 min later, returned to normal. (Sparks confirmed Dean)." NASA catalog weight=5. NASA catalog ID #1267. ALPO/BAA weight=3.
1970 Jul 11 UT 20:35-20:45 During a TLP alert for Proclus, Jamieson saw nothing unusual, but found instead that Secchi was quite bright. NASA catalog weight=5 (very good). NASA catalog ID #1267. ALPO/BAA weight=1.
On 1983 Sep 15 at UT 05:20-05:24 Louderback (South Bend, WA, USA, 8" reflector and 3" refractor, seeing poor) found that the west wall of Eimmart was unusually bright (8.3) and apparently it was almost as bright as the "WEBS(of Aris?) at its brightest". The crater was apparently normal again on Sep 20 and 26. The Cameron 2006 catalog ID= 228 and the weight=3. The ALPO/BAA weight=2.
2009 Apr 13 UT 18:55-20:00 J. Adee (UK) and later A. Jarwaski (UK) saw Mons Pico to be incredibly bright. Adee reported naked eye visibility, though this does not show up in later CCD images. Jarwaski saw another nearby Mt very bright as well. This has been assigned an ALPO/BAA weight of 1, though I suspect it is just normal for Pico to get quite bright at sunrise.
Patches of brightness seen in the area between craters Aratus and Joy. Seemed to the observer to be perhaps slightly brighter than one would expect - the observer thought that their observation only barely constitured a TLP but decided to send the report in anyway. This has been assigned an ALPO/BAA weight of 1.
On 1990 May 03 at UT 02:03 D. Darling (Sun Praire, WI, USA, seeing steady) observed a point of light inside Alphonsus just to the north of the central peak, along the "center ridge". It was seen again, half way between the central peak and the noth west rim - along the ridge. All other features were normal. The Cameron 2006 catalog ID=403 and the weight=3. The ALPO/BAA weight=3.
Purbach 1970 Apr 14 UT 12:00-14:00 Observed by Osawa (Awajt-Shima, Japan, 8" reflector, x288) "Photos in blue and orange taken. Ill- defined obscur. in blue photo in S. part of crater compared with orange. (neg. is so faint it is doubtful. Apollo 13 watch. Similar to Alter's findings in Alphonsus)." NASA catalog weight=2 (low). NASA catalog ID #1250.
SW of Pico 1844 Apr 25 UT 20:00? Observed by Schmidt (Athens, Greece, ? refractor) "A bluish glimmering patch of light not quite within the dark side" NASA catalog weight=4. NASA catalog ID #123. ALPO/BAA weight=3.
On 1972 Apr 21 at UT19:01 Mattingly (Apollo 16 commander, in orbit around the Moon, using his naked eyes) saw a bright flash from below his horizon on the lunar farside (approximate longitude=180 deg). he was dark adapted at the time. However no sesimic event was recorded and so Cameron suspects that this was not a meteor impact but a cosmic ray striking his eye. The Cameron 1978 catalog ID=1331 and weight=3. The ALPO/BAA weight=3.
Alphonsus 1967 Aug 13 UT 18:40-18:55 Observed by Horowitz (Haifa, Israel, 8" reflector?) "Glow or hazy patch seen while using filters. Brighter than background. Not seen after 2055 or next nite" NASA catalog weight=3 (average). NASA catalog ID #1041.
Plato 1952 Apr 04 UT 02:45 Observer: T.A.Cragg (Mt Wilson, CA, USA, 31cm reflector, x420, seeing fairly good, transparency fair) - Obscur. of floor (seen a few hours after Wilkins & Moore obs. confirm.?) " - indeed Haas in Stolling Astronomer 2002 Vol 45, p29 states that Cragg was amazed to see Plato's floor with absolutely nothing on it! He was able to draw details elsewhere in other features. NASA catalog weight=5. NASA TLP ID No. #551. ALPO/BAA weight=2.
On 1972 Apr 22 at UT 17:30-18:15 Iwanoff (60mm refractor, 1000mm focal length,transparency 3 out of 5 and seeing 3 out of 5, located at 53deg 5' N and 8deg 45'E) At Censorinus a diffuse bright area, greater than the crater itself, yellow to white in colour. Published in Hilbrecht and Kuveler, Moon and Planets, 30 (1984) p53-61. ALPO/BAA weight=1.
On 1988 Jul 23 at UT03:07 D. Darling (Sun Praire, WI, USA, 12" reflector, x150, seeing = 6/10) discovered that the dark area on the floor of Proclus, seen earlier by UK observers was still present, but less so (?) and the shape changed. When viewed through a green filter it was less distinct. "Change with two other filters. Polarizer gave a circular shape with a knot on SE side & W58 in White." The measured brightness of Proclus was 9 on three sides and 8.5 on its west rim. The floor was 5.5, but the dark spot was 4. Alphonsus, Bullialdus, Copernicus, Eratosthenes, Plato and Ptolemeaus were all normal. The Cameron 2006 catalog ID=332 and the weight=1. The ALPO/BAA weight=1.
Tycho observed by G. North (UK) seen to have greyness inside parts of its shadow. Confirmed by J.D. and M.C. Cook Possibly light scattered of illuminated wall into shadow or highland starting to break through the shadow. ALPO/BAA weight=2.
Morales of France?, observed "an illumination" in Kepler on 1884 Feb 05 at UT20:00?. The Cameron 1978 catalog ID is 241 and the weight=1. The ALPO/BAA weight=1.
On 1974 Mar 02 at UT 23:00 Fitton (Lancashire, UK, 8.5" reflector, x200, seeing = excellent and transparency = excellent) observed "A fine deep red line seen at 1st contact with B-ring of Saturn. Nothing unusual at A-ring contact. Persisted during occult. of B-ring. It divided into 2 components & space between B-ring & globe cutting ring into 2 disjointed ends persisted till dark limb passed onto globe of Saturn, then a short red line corresponding exactly to chord of planet disk defined by lunar limb. It increased in length as occult. progressed. It suddenly vanished after 3/4 of globe had been occulted. No afterglow at spot on limb, no irreg. at limb could be seen. Obs. eliminates Saturn, telescope, & atmosp. as possible cause. Suggests refraction from tenuous atm. of destructive interference of reflected light from very small angle at limb, or diffraction of Saturn light grazing limb". The Cameron 1978 catalog ID=1389 and weight=1. The ALPO/BAA weight=1.
Linne 1867 Jan 14 UT 20:00 Observed by Knott (England?) "White covering had seemingly disappeared, was a dark spot. Definition (seeing?) was poor." NASA catalog weight=1 very low. NASA catalog ID #148.
On 1972 Apr 22 at UT 18:58-00:28 Hopp (75mm refractor, 1200mm focal length,transparency 4 out of 5 and seeing 4 out of 5, located at 52deg 30' N and 13deg 15'E) Censorinus brighter than normal relative to Proclus.

On 1960 Feb 06 at UT14:30 Morozov (Moscow, Russia) saw with the naked eye a bright point inmovable but with brightness variations in dark part of Moon, 3days past first quarter, 2days before SR! (says Cameron). Cameron 1978 catalog ID=728 and weight=3.
On 1975Mar22 at UT 21:17-21:23 Findlay and Ford (Mills Observatory, Dundee, UK, 25cm refractor, Wratten 25 and 44a filters used) A white spot was observed on the rim of Bulialdus that was perhaps slightly brighter in red than in white light. The observers however decided that they did not regard this as a TLP. This is a BAA Lunar Section Observation. ALPO/BAA weight=1.
On 1997 Dec 09 at UT 18:42-19:02 P. Salimbeni(Cugliate Fabiasco, Italy, 20cm reflector) observed colour on the northern edge of the crater - 23A filter used. This is a UAI reported observation and has come from this organizations web ste. The ALPO/BAA weight=3.
On 1975 Mar 22 at UT22:10-22:25 T.Flynn (Edinburgh, UK, 30cm Newtownian, x75) observed 3 large areas on the floor of Plato to be delicately darker in the blue filter. There were of different darkness. He did not regard these as TLP, but permanent blinks. This is a BAA report. The ALPO/BAA weight=1.
Alphonsus - 1966 Aug 27 UTC 06:05-06:25 observed by Haris, Eastman, Bornhusrt, Cameron, astronet observers (Tucson, AZ, USA - 21" reflector x200) and by Corralitos observatory (Organ Pass, NM, USA, 24" reflector) "W. dark-haloed area varying & the small dark-haloed (40%) area also varying. Seen by others present incl. the author (WBC) who attributes the variations to "seeing". Not confirmed by Corralitos MB." NASA catalog weight=1 (low). NASA catalog ID=968.
Ross D area - 1966 Aug 27 UT 06:06-06:25 observed by Harris, Eastman, Bornhusrt, Cameron, astronet observers (Tucson, AZ, USA - 21" reflector x200) and by Corralitos observatory (Organ Pass, NM, USA, 24" reflector) "Obscuration on E. wall, bright area E. of crater at its brightest. (I (WSC) was present at obs. but did not note anything not attributable to bad seeing, but am not familiar with the area in normal aspect. Others present did not see anything unusual, but Bornhurst & Eastman confirmed). Corralitos Obs. found due to changing light conditions. NASA catalog weight=1. NASA catalog ID=967. ALPO/BAA weight=1.
On 1988 Jul 25 at UT03:15 H. Davis (Madison, WI, USA) stated that Proclus was normal apart from a "slightly darker area in SW (Ast) SE (IUE) corner." The Cameron 2006 catalog ID=334 and the weight=0. The ALPO/BAA weight=1.
On 1975 Mar 23 at UT 20:40 P.W. Foley (Kent, UK) found a brownish colour on the north west wall. This is a BAA Lunar Section report. The ALPO/BAA weight=2.
Bullialdus 1979 Oct 31 UT 20:20-20:30 G.W. Amery (Reading, UK) observed a plateau area to be dark and distinct in blue light (Wratten 44a), but only just visibly in red (Wratten 25) and yellow light. Observer wonders if this is natural surface colour? ALPO/BAA weight=1.
SE limb of Moon 2003 Aug 08 UTC 20:50 Observer Brook (Plymouth, UK) x70 60mm OG on a very hot evening, when I saw a fountain-like appearance suddenly "squirt" from the SE limb. Seeing not particularly good, but not so poor as to account for what was seen. Duration of phenomenom perhaps a fraction of a second, hight of pehaps a few miles. Thought I saw another one a few minutes later. - observer suspected hot weather and Moon's low altitude" The ALPO/BAA weight=1.
Gassendi - 1966 Sep 25 UT 20:20-20:50 observed by Moore and Moseley(Armagh, N.Ireland, 10" refracfor x140) "Reddish patches, regarded dubious, owing to low altitude of the Moon". NASA catalog weight=1. NASA catalog ID #981. ALPO/BAA weight=1.
On 1991 May 24 at UT 23:10 M.C. Cook (Frimley, UK) found the apron region of Censorinus had a very dull white apron, but was not diffuse. A sketch was supplied by this experienced observer. The Cameron 2006 catalog ID=428b and the weight=3. The ALPO/BAA weight=2.
2004 Jul 28 UT 07:25-07:31 R. Dewitt (Transparancy very poor due to forest fire pollution - Moon looks red, USA, location: Mill Creek, WA) observed several pin point-like orange flashes of light occur (2-5 sec duration each and static wrt the Moon's surface) across the bright illuminated side of the Moon with the naked eye.

No other of 6 spectra of other features on the plate show it. No other of 20 spectra of Plato, including another on the same nite show it. Further reduction & analysis remain to be done." NASA weight=5. NASA catalog ID=#1291. ALPO/BAA weight=5.
Atlas 1954 Mar 23 UTC 00:00? Observed by Delmotte (France?) "Violet tint in crater" NASA catalog weight=3 (average). NASA catalog ID #562.
Plato 1886 Nov 14 UT UT 21:45 Observed by Lihou (France?) "Brilliant band N-S, area marked G in NE was only slightly visible, poorly defined. Drawing (there were rays on the floor)." NASA catalog weight=3 (average). NASA catalog ID #253.
Plato 1966 Aug 05/06 UT 23:37-02:58 Observers: Corvan, Moseley (Armagh, N.Ireland, 10" refractor, x280) and Ringsdore (England, 8.5" reflector) "Several red glows at different places at different times. Each lasted a few min. (not confirmed by Ringsdore. Given as 8/4 in MBMW) NASA catalog weight=4, NASA catalog ID=#964. ALPO/BAA weight=2.
On 1958 Jul 14 at UT 21:00 Classen (Pulsnitz Observatory, East Germany, 8" refractor) observed Kepler to be 0.5 magnitudes brighter than Aristarchus, normally it is the other way around with Aristarchus being 0.3 brighter than Kepler. The Cameron 1978 catalog ID=1084 and weight= 3. The ALPO/BAA weight=2.
On 1989 Apr 26 at UT 10:22-10:44 D. Darling (Sun Praire, WI, USA, 3" refractor, x36-x140) found that the eastern half of Plato crater was dark - and he checked this using several eyepieces. moderate magnification resolved the dark region into bands, but too high a magnification (x140) made the bands dissappear. The Cameron 2006 catalog ID=362 and the weight=0. The ALPO/BAA weight=1.
On 1982 Oct 08 at UT 04:15-04:30 W. Cameron (Silverspring, MD, USA, 3.5" reflector, x160, Seeing-very good) suspected blue tinge on north west rim and brown/red on south east rim of Aristarchus crater + focus was slightly difficult. No similar colour effect seen on other craters. Cameron 2006 catalog ID=186 and weight=1. ALPO/BAA weight=1.
On 1982 Oct 08 at UT 04:15-04:30 W. Cameron (Silverspring, MD, USA, 3.5" reflector, x160) found that Clavius had a "D" shaped crater on its outskirts that made it appear to have a ridge crossing through it. Cameron 2006 catalog ID=186 and weight=1. ALPO/BAA weight=1.
Tycho 1983Aug30 UT 00:15-00:18 R. Moseley (Coventry, UK, 6" f/10 reflector, x60, transparency very good, seeing III, improving with altitude) attention initially caught by the impression of a rosy colouration along the NW crest and outer wall. For perhaps 2-3 min this persisted - before fading entirely. The observer felt that the cause may have been psysiological - or short-lived spurious colour. However interestingly nearby craters did not show the effect. A sketch was made over a longer time span 00:15-00:40UT. ALPO/BAA weight=1.
In 1919 Feb 21 at UT 22:00? an unknown English observer observed in Lexell crater an intensely dark line going out from it. The Cameron 1978 catalog ID=370 and weight=1. The ALPO/BAA weight=1.
On 1981 Sep 20 at UT 08:00-09:40 D. Darling (Sun Praire, WI, USA, 12.5" reflector, x342, seeing=excellent) detected the small crater on its western rim But not on the eastern floor. This was odd because both are equal in size, furthermore smaller craters could be seen and the Moon was at a high altitude above the horizon, so seeing not a problem. Cameron 2006 catalog ID=154 and weight=3. ALPO/BAA weight=1.
Linne 1918 Apr 04 UTC 01:00? Observed by Markov (Russia) "In place of crater only a hill 2km in diam. was vis. (seen in dark). " NASA catalog weight=1, low, NASA catalof ID #368. ALPO/BAA weight=1.
"Observed early morning Moon, with 60mm OG x120, from 02-20 to 02-45 hrs UT targeting Plato, Aristarchus, and Alphonsus. From 02-20 to 02-30 hrs UT. Aristachus showed a faint pink colouration, where the light material contacted the darker Mare surface. This was not seen after 02- 30 hrs UT." Transparency very good, seeing somewhat unsteady at first, improving later on. The ALPO/BAA weight=2.
On 1978 Jan 02 at UT23:00? A.V. Arkihpov and A.R. Kharkov (USSR) observed in the terminator region (near Adams?) a flash enclosed by a fuzzy envelope (180x120 arc seconds in size). The TLP faded away over 30 seconds. Cameron says that this is the first example of many photographs that registered activity. The Cameron 2006 catalog ID= and weight=5. The ALPO/BAA weight=2.
