The ALPO/BAA weight=3.
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.

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.

In 1866 Oct 16 at UT 23:00 Schmidt (Athens, Greece, 7"refractor) observed that Linne crater had disappeared and been replaced by a white patch with a small hill or craterlet. White part seems to increase in size. Cameron says probably not a TLP. The Cameron 1978 catalog ID=145 and the weight=0. The ALPO/BAA weight=1.
On 1982 Jul 28 at UT20:38-20:48UT A.C. Cook (Frimley, Surrey, UK, 12" reflector, seeing IV-V, some spurious colour prsent) observed that the central peak of Alphonsus was brighter in red light than in blue, so much so that at the start of the session the peak could hardly be seen in blue light. The central peak varied in brightness in red light but not in white light. The central peak of arzachel was brighter than that of Alphonsus in white light but had no colour - Arzachel's central peak did however appear to fade in brightness over time (or was it Alphonsus getting brighter?).

On 1979 Sep 29 at UT10:00-12:00 S. Turner (Maryborough, Australia) observed a strong beacon like flash in white light that moved back and forth in the east wall of Plato (very bright) and Mons Pico. tried changing eyepiece and the field of view, but this wasn't the cause of the effect. A check at 11:07UT did not show the effect, but it was back again by 11:18UT being more pronounced at Mons Pico than the east wall of Plato. SSW of Mons Pico was also blinking slightly. At 11:32 the blinking effect was irregular 5-10 sec and this continued until 12:00UT. Cameron 2006 catalog ID=71 and weight=0 but she suggests atmospheric scintillation as a cause. ALPO/BAA weight=1.

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 1976 Nov 30 UT 19:15 T. Flynn (Edinburgh, UK, 29cm reflector, Wratten 25 and 44a filters) observed that there were two whitish semi-circular tide like marks enclosing two dark patches adjoining the interior west wall The observer was puzzled because if these were two masses of spawning foot hills, then why would the cental areas, presumably the higher parts, be dark - when the contrary is usually the case? ALPO.BAA weight=1.
Copernicus 1976 Nov 30 UT 19:40 T. Flynn (Edinburgh, UK, 29cm reflector, Wratten 25 and 44a filters) observed that the Copernicus craterlet chains werebetter seen through a red filter than a blue. ALPO.BAA weight=1.
Purbach 1976 Nov 30 UT 19:40 T. Flynn (Edinburgh, UK, 29cm reflector, Wratten 25 and 44a filters) observed that the crater interior was better see through a red filter than a blue. ALPO.BAA weight=1.

The Cameron 1978 catalog ID=1302 and weight=2. The ALPO/BAA weight=2.
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.
On 1988 Jul 24 D. Darling (Sun Praire, WI, USA, 12" reflector, x150, S=7/10, T=3) observed the following in Proclus: "At 0213 the previously observed gray area was 1/3 of July 22 and V shaped and fanned out across the floor. Could see hint of knot seen before. Craters named in 7/23/88 (#319) were all normal this time too". Is it possible that this report refers to the crater "Gray" rather than "Proclus" as the column field suggests in the Cameron catalog? The Cameron 1978 catalog ID=333 and weight=5. The ALPO/BAA catalog weight=2.
Dawes 1973 Feb 12-23 UT 22:30-01:20 Observed by Porter (Narragansett?, RI, USA, 6" reflector x96, S=9, T=0-4, alt=55-75deg?)

On 1984 Jun 09 at UT 04:55-05:14 P. Jean (Outremont, Canada) detected in the dark side of the Moon, a few km east of Kies crater, a bright point that should not be poking out of the shadow (according to Foley). The Cameron 2006 catalog ID=244 and the weight=3. The ALPO/BAA weight=2.
On 1974 Jan 03 at UT 18:30 a Norwegian amateur astronomer, (Hoydalsvik (Hakonsgate, in West Norway, 60mm refractor) photographed the Moon using High Speed Ektacrome (400ASA) film with good focus. The TLP was located on the southern slope of Sasserides H and was pink in colour with some buish in it. The coloured area was circular with a diameter of 0.5 minutes of arc.

(19:00 originally given probably local time) Miranda (Plaui, Brazil, 4" refractor, x80) observed two grooves going from east to west, broadening towards the west, across Archimedes. A drawing was supplied. Apparently this was the first time that this was ever seen. Cameron suggests rays? and also says that in fact a similar phenomenon reported before in neasrly the same position (Apollo 15 watch?). The Cameron 1978 catalog ID=1303 and weight=2. The ALPO/BAA weight=1.
On 1882 May 27 ay UT 20:00 an unknown observer (10" reflector) saw a bright luminous ray near west (astronomical?) wall on floor of Plato. Cameron suggests sunlight between peaks?. The Cameron 1978 catalog ID= 233 and weight=0. The ALPO/BAA weight=1.

Om 1987 Sep 04 at UT 03:00 J. Caruso (Middletown, CT, USA, 3" refractor, x155, S=6/10 and T=8/10) found that Bianchini G was not visible, however Heraclides E, Helicon G, and indeed many other smaller craters could be seen. There were two small mountains in the general area of Bianchini G. and a mare ridge - all these were clearly seen. Caruso states that Bianchini G should normally be much more clearly seen than the other features mentioned and is the same size as Heraclides E. The Cameron 2006 catalog ID=305 and the weight=3. The ALPO/BAA weight=1.
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 1955 Jan 05 at 01:00-01:30 UT D.A. Logue (Larchment, PA, USA, 15cm reflector at x340, seeing Good) saw a strange blue light above the surface of the Moon where the night and the day meet. He observed this light for more than 30 min and it did not appear to move. It appeared like a star in that the rays of light came from it. The observer adds that he first thought thst the objects was a star, but later decided that it had to be on the Moon itself. A drawing shows the blue spot near the rugged south west (IAU?) limb of the Moon. The editor of the Strolling Astronomer (Vol 8, No. 11-12, Nov-Dec 1954, p146) was unable to identify the craters drawn. The editor speculates that the observer saw a high mountain peak with its summit in sunlight and detached from the illuminated regions - however this would not explain the blue colour.

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.
Plato 1872 Jul 16 UTC 21:00? Observed by Pratt (England?) "NW portion of floor was hazy" NASA catalog weight=3 (average). NASA catalog ID # 179.
On 1982 Aug 01 at 00:00-01:00 K. Marshall (Medellin, Columbia, 12" reflector, seeing I-II) noted shading on the east floor of Plato that was apparently lighter than the rest of the floor and this was seen at both low and high magnifications. Foley notes that this was unusual. There were three craterlets visible on the floor - the central one was the brightest. Cameron 1978 catalog ID=178 and weight=3. ALPO/BAA weight=1.
A.S.Williams of West Brighton, UK, using a 5.25" Calver, x150 and definition fairly good. Observer noticed that the Mare seemed covered with a close network of innumerable streaks, and spotted with countless numbers of light specks, so that it would hardly be possible to delineate them all in one night. The spots and streaks together must have numbered ~1000. The observer had never seen anything like the number of spots and streaks. Peirce A, was not at all easy to se and neighboring spots almost as bright made it difficult to distinguish which one was Peirce A. ALPO/BAA weight=3.
On 1976 Apr 10 at 21:15-21:49UT S.Spencer (60mm refractor x60, seeing quite good) noticed a faint red glow at the south west wall of Gassendi covering a span of about 35 deg arc. The observer had some doubts about this because they were using a small telescope, but thought that they ought to report it, just in case. A BAA Lunar Section report. ALPO/BAA weight=1.
Plato 1966 Sep 25 UT 23:12-23:35 Observed by Moseley (Armagh, Nortern Ireland, 10" refractor, x140) "Eng. moon blink sys. blinks inside the crater. Very dubious due to low alt. of moon." NASA catalog weight=1 (very low). NASA catalog ID #982.
On 1985 May 30 at UT 20:10-23:54 P.Moore (Selsey, UK, 15" reflector) and at the same time Doherty (Sussex, UK, 15" reflector) observed a strangely bright and pink/red north rim of Aristarchus crater during UT20:20 and 20:36UT. The effect reduced between ~20:39 and 20:44UT. M.C. Cook (Frimley, UK) found the northern wall to have a red/purple colour but the effect vanished after 50 minutes. Cook also saw a "V"- like notch in the NW crater shadow and this appeared to be bigger than normal. G. North (Sussex, UK) saw a tinge of pink colour on the northern rim and a bit later a "ruby red" colour on the north-west wall - again this effect lasted 50 minutes. Moseley verified the colour. Finally M. Hather (Yorkshire, UK) suspected the north wall of Aristarchus to be blue in colour. Cameron suspects that this TLP is not spurious colour because it is in the wrong place. The Cameron 2006 catalog ID=276 and the weight=5. The ALPO/BAA weight=4.

Altho. a deep shadow is normal to the W. of the cape at this period, (then cape must have a slope > 30deg!). he wondered if shad. was more extensive than usual? Prout noted a dark inky coma- shaped spot. Dundee obs. concluded it was a shadow. Took photos. Analysis of them was underway at time of rep't." NASA catalog weight=5 (very high). NASA catalog ID #1462.
On 1963 Nov 28 at UT 05:00-06:00 Greenacre, Barr, Hall and Dungan (Flagstaff, AZ, USA, 24" refractor) observed a deep violet area form on the western exterior of Aristarchus, and a less deep violet area form to the eastern edge of Aristarchus. As these were becoming stronger, a blue-like haze formed on the sunlit floor of Aristarchus, that obscured underlying detail. The ALPO/BAA weight=2.
nr Fra Mauro 1970 Aug 14 UT 05:00? Observed by Bell (Californina). "Bright blue-white flare (meteor?)(call for obs. at Fra Mauro at perigee because of moonquakes there -- therefore biased to tidal hypothesis.

On 1994 Apr 23 at UT 03:30 the US Navy Clementine Spacecraft, in orbit around the Moon, obtained images of the Cobra Head region of Aristarchus crater that suggested a ~15x colour ratio increase (0.4 microns / 1.0 microns) in comparison with images obtained on 1994 Mar 03. This was presented as a poster paper 18.04 at AAS 31st DPS meeting. However it was later suggested that this was due to incorrect radimetric calibration procedures being followed. The ALPO/BAA weight=1.

On 1985 May 31 at UT 20:23-22:00 G. North (Sussex, UK, turbulent seeing) found Torricelli B at 20:23 to be mauve in colour and to be very bright. However the colul had gone by 20:29UT. "Varied in albedo 2s then image blurred at 5-10s (atm) at 2034 became pink). At 21:35UT M. Mobberley (Suffolk, UK) found a white patch in the crater centre and a mag 8 flash was seen (confirmed independently by a 2nd observer ~ 113km away)- there was no shadow. At UT 20:30 P.W.

On 1985 Sep 28 UTC 20:54-23:52 P.W. Foley (Suffolk, UK) found (actually before 20:54 UT) brightness variance in Torricelli B. J.D. Cook (Frimley, UK) observed a brief blue coloured patch somewhere in the Torricelli B region, but could not pin it down precisely. At 22:50UT M.C. Cook (Frimley, UK, 30cm reflector, seeing III - occasionally V, transparency moderate to good) Found the crater to have an elongated appearance (in SSW-NNE direction) in white light, similar to the previous night. A bright elongated spot was seen on the NNE floor, close to where the wall should be. Not able to define the rim. There was a very dark surrounding area to the crater, similar to what it was on the previous night (roughly 1/4 brightness of Censorinus). 23:04UT brighter in yellow, then red, then blue. At 23:10 it was seen that blue filter dulled the crater - this was odd because both Censorinus and Proclus were brighter in blue, which is what he would normally expect. At23:15 UT Censorinus was brighter in blue, then yellow then red filters and some orange spurious colour seen to the south of Censorinus. At 23:23UT no spurious colour seen on Proclus or Censorinus. 23:46UT Torricelli B elongated as before, but a very faint ray might have been seen to the south west of the rim.

Fainter than Proc., Cop., & Tycho. Others rated brightness in order-- Hell, Stevinus, Furnerius, proc.; & Proc., Tycho, Hell, Aris. Photos confirmed dimness of it. For some observers it became invis. at S=II (good). Good ranked at least 4 other craters brighter than Aris. & that at 2035h it dimmed. Earthshine cond. extraordinarily good. Peters, at S=IV (fair?) rated Aris. brightest". At 23:50UT LeCroy Jr and Sr (Springfield, VA, 4.5" reflector, S=7) observed four glowing spots on the Moon during a lunar eclipse (including Aristarchus).

At 23:50UT 3 of these patches emerged from the dark and appeared as bright spots compared to other craters "Älbedo=10+". At 23:55UT a ray appeared out of the north east rim of menelaus (Normal?). It appeared just before the artea emerged and increased in brightness. At 23:58UT it decreased and continued to do so. The north east edge of Menelaus appeared very dark at the point that the ray was extending from SW edge (a ridge there) and apperared to obscure features along its path (Albedo=9).

On 2012 May 25 UT 05:35 Brenner F crater was recorded in a larger area image by M. Collins (Palmerstone North, New Zealand, ETX-90 with LPI imager (monochrome mode) - seeing not good). He took a sequence of 108 images from 05:35-05:40UT, and in the 65th frame, a light spot, approximately 4 pixels wide can be seen just outside the western illuminated rim of Brenner F. It is not visible in any other frames. The exposure time was 0.125 Sec. Because the western edge of the spot is very sharp, and the rest of the Moon is slightly blurred due to seeing, it is thought that this was most likely a cosmic ray event in the CCD camera - the 4 pixel width was perhaps contributed to by the image compression. It could also be some bright surface spot that was made invisible most of the time by poor seeing, and then during a brief period the atmosphere is sharp enough at that locality to make it visible. ALPO/BAA weight=1.
