In 1821 May 06 at UT 21:45 Ward (England? Large aperture telescope, x80), Bailey (England?) and Olbers (Bremen, Germany, refractor) observed in the Earthlit part of the Moon an apperent small comet like feature extended from Aristarchus towards Grimaldi. The light was similar to a glow worm. The observer had never seen anything like it. The cameron 1978 catalog ID=89 and weight=5. The ALPO/BAA weight=3.
Cusps 1953 Apr 18 UT 21:00? Observed by Wilkins (Kent, England, 15"? reflector) "Faint extension of the cusps. (high peaks in sunlight)." NASA catalog weight=2 (low). NASA catalog ID 558.
Cusps 1953 Apr 18 UT 21:00? Observed by Wilkins (Kent, England, 15"? reflector) "Faint extension of the cusps. (high peaks in sunlight)." NASA catalog weight=2 (low). NASA catalog ID #558.
Observations made by Challis of Cambridge, and N. Pogson of Hartwell, both of the UK. Before the occultation, Saturn's rings were distorted. A dark border was seen around the Moon. Just before re-appearance a sea green colour was noticed. Cameron 2006 catalog extension ID=5 and weight=2-5. ALPO/BAA weight=1.
On 1969 Jul 20 at UT 0845 McIntosh (Auckland, New Zealand, 14" reflector) saw Aristarchus crater to be brighter in red light. This was during the Apollo 11 watch. The Cameron 1978 catalog ID=1173 and weight=3. The ALPO/BAA weight=3.
On 1975 Mar 18 at UT17:30 M.Kidger (Winterbourne Down, Bristol, UK, 60mm refractor, x36, very good conditions with a very sharp image and the sky was almost perfectly clear apart from a very few small clouds). In Mare Crisium it was observed that only a ray of Proclus could be seen to cross the floor - normally there are at least four craters visible inside mare Crisium on good nights and at least one being visible under bad conditions. So despite it being very clear and the image quality being good, the observer found it odd that no craters were visible on the floor of mare Crisium. This is a BAA Lunar Section report. The ALPO/BAA weight=2.
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 1969 Jul 20 at UT09:30 Whelan (Wellington, New Zealand, 10" and 6" reflectors. Other observers involved were: Mackrell (New Zealand, 6" reflector) and Spellman (4" reflector) observed Maskelyne crater undergoing a whitish glowing brightening. Shadowy filling of whole crater. Apollo 11 watch. The Cameron 1978 catalog ID=1179 and the weight=3. The ALPO/BAA weight=2.

Hue seen thruout obs. (true ground color? or seeing ? or true LTP?) thin clouds. (Apollo 10 watch)". NASA catalog weight=3 average. NASA catalog ID #1141.
On 1988 Jul 21 at UT 01:00? an Unknown observer (name and geographical position not given in the cameron catalog) detected a darkening on the floor of Proclus crater - this was also seen by other observers - some of whom were making observations independently. The Cameron 2006 catalog ID=330 and the weight=1.
On 1970 Apr 13 at UT09:00-09:03 Whelan (Walters, New Zealand, using a 10" reflector) observed Menelaus to have a deep red cloud that seemed to surge upward from outside the southern edge of the crater wall and disperse around the outside edge, spreading out on reaching Mare Serentiatis. All clear again though by 09:03UT, (Apollo 13 watch). Drawing supplied. Cameron 978 catalog ID=1246 and weight=3. ALPO/BAA weight=3.
On 1941 Jan 06 at UT04:00 Barcroft (Madera, CA, USA, 6" reflector) saw an anomalous shadow in Arzachel crater. Cameron 1978 catalog ID=482 and weight=3. ALPO/BAA weight=3.
Flash seen in Ptolemaeus (A?) - possibly a meteor. Cameron 1978 catalog weight=1. Cameron 1978 catalog ID=863.
Jansen 1966 Aug 24 UT 04:15-04:25 Observed by deBerard (Flossmoor, IL, USA, 6" reflector, x360, S=V, moonblink used) "Bright green glow -- using red & blue filters & green polariz. filter." NASA catalog weight= 3 (average). NASA catalog ID #965.
On 1988 Jul 22 at UT 02:15-04:00 P.W. Foley (Kent, UK, 11" reflector) made a sketch of a dark area of the (East) floor of Proclus that revealed a large anomalous dark region - there should be no shade here when the sun is at an altitude of above 50 deg!. BAA lunar section archives reveal similar dark shadings - however on this night it was a different shaped dark area. The appearance was confirmed by several observers. Foley reported that the region affected stretched from Proclus to Theophilus. The TLP was seen in the USA too by D, Darling as early as 01:31UT and by others on his TLP network - brightness measurements of the "c.p." were 3.5 and the remainder of the floor was 5.5. However the observers did not all agree on the same position for this dark area. The Cameron 2006 catalog ID= 331 and the weight=2. The ALPO/BAA weight=2.
Herschel 2005 Aug 13 UT 00:07-00:29 Observed by Daniel del Valle Hernandez (Aguadilla, PR, 8"SCT, x225, S=7, T=4) "Interesting configuration of shadows with umbra and penumbra. Effect seemed to reduce over time." An ALPO report. The ALPO/BAA report=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 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.
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 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.
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.

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.
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 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 1974 Mar 3 at UT 19:06-20:20 J-H Robinson (Teighmouth, Devon, UK, 10" refractor, x200, seeing=poor) got a Moon Blink reaction on the South east wall of Plato, adjacent to the rim shadow and alerted the BAA TLP network. Ford reported a negtive result at 19:35UT, although Robinson was still getting a blink reaction at 19:40UT, albeit fainter, red at times. Findlay at 19:43-19:52 and 20:00-20:05 saw nothing unusual. Robinson at 19:56UT no longer saw a blink, but it returned at 20:05UT. Light in bothred and blue filters. Not steady, but coming and going and gone at 20:09UT. Moore at 19:59-21:00, kennedy at 20:12-20:30, Taylor at 20:48-21:03 and Fitton at 20:05UT all got negative results. The latter time coincides with Robinson's second blink reaction. Cameron 1978 catalog ID=1390 and weight=1. ALPO/BAA weight=1.
On 1981 Sep 08 at UT 21:28-21:34 P. Madej (Huddersfield, UK, seeing III-IV and trasnaparency good) observed a light orange transparent cloud extending from the north east inner corner across over the floor of Plato. Camero comments that this report was confirmed by 3 othr observers. The shape of this clud varied. The Cameron 2006 catalog ID= 153 and weight=4. The ALPO/BAA weight=3.

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 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.

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.

Herodotus 2002 Sep 18 UT 22:00 Observed by Raffaello Lena (GLR, Italy). Event described was of two pseudo-peak/hill-like features, one on the southern floor of the crater, and another just slightly to the NW of the centre. on the southern floor of the crater. Lena suspects a combination of seeing effects and albedo markings on the floor. However this effect of two spots on the floor has not been repeated again.For further information, theory, and a sketch please see Fig 5 in this web link: http://utenti.lycos.it/gibbidomine/analisi123.htm ALPO/BAA weight=2.

On 1983 Sep 20 at UT 05:08-06:13 Louderback (South Bend, WA, USA, 3" refractor, x150, seeing poor and chromatic aberation on the limb) detected "purple"in the vicinity of Aristarchus crater and this was stongest on the north and north west external rims, however there was no "violet glare"from inside the crater. However the region of the central peak was very bright - though he could not detect the central peak. The brightness of the TLP was 4.5 and it should normally be 3 (nimbus area). Near the "big plain"it was 7. The chromatic aberation seen on the crater. There was also violet on the northen wall of Herodotus crater and the Cobra Head. Īt appeared dark blue in the blue filter", the surrounds remained gray". Apparently on the 26th the"ring was still dark with faint violet - nearly normal". Cameron comments that the TLP was due to spurious colour. The Cameron 2006 catalog ID= 229 and the weight=3. The ALPO/BAA weight=2.

Proclus 2001 Nov 04 UTC 07:00-07:43 "Robin Gray of Winneucca, Nevada, U.S.A. reported a contrast effect and brightening in the crater Proclus. Using a 15.2 cm refractor he conducted a Moon blink search with Wratten 25a and 38a blue filters. His report goes as follows: Moon Blink carried out. In Red 25 Proclus looked nearly the same as in white light. Through the Blue 38a filter, however, only the brilliant lit south east wall was clearly visible. The northeast wall was very dim with this filter. With no filters the NE and SE wall were brilliantly lit, the SE wall was almost as bright as Aristarchus. A thread like strip along the NW wall, possibly the rim of the crater, was also brilliantly illuminated. The interior of the crater was a featureless stygian black with the exception of a brilliant (intensity 9) thread of light that ran parallel to the illuminated east wall. Whether this was an L.T.P. or an optical effect of atmospheric turbulence is unknown, did not see anything similar elsewhere along the terminator though" ALPO/BAA weight=3.

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.
