On 1979 Oct 04 at UT21:05-23:40 P.W. Foley (Kent, UK, 12" reflector, x360, seeing=II) detected colour in Aristarchus (and also in Bullialdus - there was a TLP alert at this time for Bullialdus) but nowehere else on the Moon. Aristarchus had a CED brightness value of 3.8 at 21:05 (though at this time no colour) and 3.4 at 23:40 and the floor was now slate blue/gray in colour. Other features remained constant in brightness. The Cameron 2006 catalog ID=72 and the weight=0. The ALPO/BAA weight=1.
Bullialdus 1979 Oct 04 UT 20:24-21:25 JH-Robinson (Devon, UK, 260mm Newt. x200 Seeing Antoniadi IV-V, Transp.=haze) observed a two bright points on the south west floor patch to be brighter in red than in blue at 21:12. The effect was still present at 20:36 but back to normal by 20:43-20:48. Amery (Reading, UK) found a possible brownish tinge on the west wall, though spuroius colour was present elsewhere on the Moon. Foley found the WSW corner darkened in blue light. Cook found pink on south rim of Bullialdus and Pedler found Bullialdus to be a confused mass with bright and dusky spots and patches - no colour seen. Cameron 2006 catalog ID=72 and weight=0. ALPO/BAA weight=1.
On 2013 Jan 25 UT 19:05-19:15 R.Braga (Milan, Italy, 115mm refractor, x267, seeing III, transparency average) observed that Plato in general was normal in appearance, but the east rim was showing a remarkable golden (yellow-golden) hue. This was a repeat illumination observation for a W.E. Fox TLp observation from 1938 Feb 14. The observer was wondering whether they were in some way biased after reading the original report desription - so uncertain over this being a TLP. In view of uncertainty ALPO/BAA weight=1.

On 1988 Apr 01 atUT01:15-03:20 H.Hill (Lancaster, UK, 10" reflector, x286) observed that east of Lichtenberg were ëxtensive rosy areas" around the northern edge of the lava sheet. Hill believes that it may have been the same effect as seen by Madler (Germany), Barcroft (USA) and Baum's (UK) 1951 observation. The colour was "ünmistakable" and nothing to do with the atmospheric spurious colour. Other features were checked. the cameron 2006 catalog ID=322 and the weight=3. THe ALPO/BAA weight=2.
Aristarchus 1976 Jan 15 UT 19:30-20:50 Observed by P.W. Foley (Kent, UK, 12" reflector) - Aristarchus was abnormally bright (Cameron suspects that this is a confirmation an explosion effect seen earlier by Greenland: "On 1976 Jan 15 at 19:45Ut Greenland (Crawley, UK, 7x50 binooculars) thought that they saw an "explosion" on the Moon (in the general region of Aristarchus) for a fraction of a second, followed by a bright spot in the same position (not an astronomer). After discussions with others, decided it was a moment of transition to greater intensity (better seeing?). Moore thinks it was atmospheric but says it should be on record. Cmeron's 1978 catalog ID=1425 and weight=5". For the Foley report: Cameron 1978 catalog TLP ID=1427 and weight=5. ALPO/BAA weight=1.

On 2012 Jan 09 UT 21:01-21:08 Hahn crater was imaged by N. Hazel (Beverley, Yorkshire, UK, Nikon D7000 with 70-300 zoom at max, with 2x teleconverter, at f9, 1/320 sec, ISO 400 – tripod mounted, mirror up), A series of images were taken. The 21:06 one showed a grey column cutting across the central floor of the crater from the west and then bisecting the eastern rim. All detail inside is completely invisble. Some (but not all) of the other images showed a more blurred view of this feature. It's possible that this was a seeing ripple effect, or just the natural appearance of shadings on the Moon at this time, however for now this will be given an ALPO/BAA weight of 1.

In 1837 Mar 19 at UT 18:00 Rankin and Chevalier (France) noted a singular appearance on the dark side. Luminous spots there & general glow on upper (S?) limb. Whole shaded part seemed to be a mixture of light & shades. The Cameron 1978 catalog ID=124 and weight=5. The ALPO/BAA weight=3.
Aristarchus 1949 May 01 at UT 20:45 H.P. Wilkins (Kent, UK, 3" refractor x100) observed Earthshine was very detailed and Aristarchus was noticeably a bright patch. Upon concentrating on Aristarchus, he observed that it flared up in brightness considerably more still for about 2 sec. During this flare up time, inner terraces and the central peak became visible. Cameron says that this was confirmed by Barcroft a few hours later???? The Cameron 1978 catalog ID=518 and Weight=5. The ALPO/BAA weight=3.
On 1979 Sep 25 at UT00:40-00:51 D. Darling (Sun Praire, WI, USA, 12.5" reflector, x62) found the crater to blow and fluctuate between magnitude approximately 4 and 5. Initially it was bright, then faded, then brightened again aggroximately x2 and then faded into the background. The Cameron 2006 catalog ID=70 and weight=0. The ALPO/BAA weight=1.
Mare Crisium 1998 Jan 31 UT 17:15-17:35 R. Braga (Corsica (MI), Italy, 102mm f8.8 refractor, x180, with no diagonal, seeing II, Transparency poor). A very bright point located at 23N 54.5E this was normal! - what was unusual was that it vanished when viewed through a blue Wratten 38A filter (this filter absorbs red, UV, and some green light). The ALPO/BAA weight=2.
In 1900 Nov 26 at UT 19:00? an unknown observer (in Europe) observed a suspicious obscuring phenom on a dark plain (mare). The cameron 1978 catalog ID=307 and the weight=2. The ALPO/BAA weight=1.
1951 Mar 13 UT 01:35:50 L.T.Johnson (USA) observed a faint flash near W limb in earthshine - just S of Grimaldi. ALPO/BAA weight=1.
On 1988 Mar 23 at UT 01:15-01:30 M. Wisniewski (Chicago, IL, USA, S=F) observed that Aristarchus was the brightest (mag 5), and only feature visible in Earthshine. It had the appearance of a steady blue-white star like point. Darling (Sun Praire, WI, USA) though observed other features as well: Proclus, Theophilus, Cyrillus and Censorinus - all of which were normal. The cameron 2006 catalog ID=319 and the weight=0. The ALPO/BAA weight-1.
Om 1990 Mar 01 at UT 19:05-19:45 M. Holmes (Rockdale, England, UK) saw a blue blinking spot near Sirsallis A until 19:15UT after which it faded and "haloed, loss of detail". The Cameron 2006 catalog ID=392 and weight=0. The ALPO/BAA weight=1. Note that in Cameron's catalog the UT given is ambiguous as 3 UTs (00:59-02:20, 18:30-18:50, 19:35-19:45) are given for 3 features (Lambert, Aristarchus and Sirsalis A) and it is not clear which is which, but it is assumed that Holmes saw the Sirsalis A event at around 19:15UT?
On 1990 Mar 02 at UT 19:35-19:50 P. Williamson (Shropshire, UK, 14" reflector, x178, seeing=good and steady) noticed a yellow-orange glow in Gassendi (from a small illumnated crater?) in Earthshine at 19:35UT and by 19:40UT it had become very bright white, afterwhich it completely faded within 10 minutes. The Cameron 2006 catalog ID=393 and the weight=1. The ALPO/BAA weight=3.
On 1993 Dec 19 at UT 16:00-17:00 S. Beaumont (Cambridge, UK, 12" reflector, x230) observed in Theophilus that the "c.p. > reddish brown tint to SW (on peak?)" but suspected that it was probably spurious colour, however no colour was seen later. The ALPO/BAA catalog ID=469 and the weight=3. The ALPO/BAA weight=2.
On 1979 Mar 04 at UT18:15-21:45 P.W. Foley, (Kent, UK, 12" reflector, x180, seeing II-I) noticed that Aristarchus was unusually bright (though colourless) - the northern part being the more brilliant. Other features seen but less visible, though still quite obvious. A CED brightness reading of 0.3 was recorded - the highest ever so far. Amery (Reading, UK, 19?" reflector, 50-100x, obtained photographs. The Cameron 2006 catalog ID=46 and weight=5. The ALPO/BAA weight=2.
On 1979 Mar 04 at UT18:15-21:45 P.W. Foley, (Kent, UK, 12" reflector, x180, seeing II-I) noticed that although other features in Earthshine were quite obvious, Grimaldi was not, though at x200 (should this be 20:00?) Grimaldi "shone with a brilliance to that of a thin cresecent of 2-3d". Amery (Reading, UK, 19?" reflector, 50-100x, obtained photographs. The Cameron 2006 catalog ID=46 and weight=5. The ALPO/BAA weight=3.
Maurolycus 2000 Aug 06 UT 23:45 observed by Gundlach (Bolivia, telescope with Sony Camcorder) "Observer reported capturing an abnormality near the rim. Darling, suspects that this is a normal appearance based upon a later observation under similar illumination." ALPO observation. ALPO/BAA weight=1.
On 1982 Jul 27 at UT 20:04 P. Madej (Newsome, Huddersfield, UK, 16cm reflector, x33, seeing I to II, transparency fair, Hoya linear type polarizer filter) observed that when the filter was used on Mare Crisium, that the north part became a bright gray when turned to 45deg, but when turned the other way it returned to normal. The ALPO/BAA weight=3.
On 1985 Oct 11 at UT 04:56-05:12 D. Louderback (South Bend, WA, USA, 4" refractor, x95, seeing=1-2-1 and transparency=4) detected a change in brightness of Mons Piton point D (his designation) during 04:56- 04:59. The whole of the east slope was affected - initially bright and then faded and there was a blue colour (detected with filters). The variabilty was 8-11sec (Cameron suspects atmosphere as the altitude was low). The brightness stabilized at 05:12UT, but variability resumed until observing finished. As a comparison Aristillus was not seen to change. The Cameron 2006 catalog ID=287 and the weight=1. The ALPO/BAA weight=1.
On 1994 Apr 19 at UT 00:00 P. Kursewicz (Epping, NH, USA) observed a dark patch surrounding Picard crater. The ALPO/BAA weight=1.
Alphonsus 1966 May 27 UT 21:10 Observed by Sartory, Moore, Mosely (England and Ireland, 8.5" reflector, 10" refractor) "Red colour on central peak area" NASA catalog ID 937. NASA catalog weight=5. ALPO/BAA weight=4.
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?). Cameron 2006 catalog ID=177 and weight=3. The ALPO/BAA weight=2.
Plato 1918 May 20 UT 18:00? Observed by Markov (Russia) "Brightness in shadow of the light sector & 1 spot" NASA catalog weight=3 (average). NASA catalog ID #369. ALPO/BAA weight=2.
On 1975 May 18 at UT2115-2145 C. Lord (St Annes-on-sea, Lancashire, UK, 76mm f/16 refractor, x170, Wratten 25, and 44a Moon blink filters used, Transparency 4.5/5, no wind, S=F). The west flank of Maginus, and the interior, appeared to be partly obscured. No other features in a similar position along the terminator were obscured. No colour blink was detected with the filters, though a pronounced red/white light blink was noted; the device employed a N.D. x4 filter. By 21:45UT the floor was no longer obscured and only Magninus G was masked in a white haze; however immediately adjacent to the terminator was an ill defined misty patch lying where the outer flank of maginus would have been visible. The rest of the terminator was sharp. The obscuration was only seen to advantage in blue and int. light, and the blue/int blink was only very slight. Findlay and McDonnell observed 21:30-23:00 using a 25cm refractor (Seeing II- III) but failed to see anything unsual. NASA catalog weight=3. NASA catalog ID #1407. ALPO/BAA weight=2.
Alphonsus 1931 Apr 25 UT 18:00 Observed by Vasilev (Russia) "The triang. dark spot close to the w.bank was not vis. after SR & appeared along the length of the term. , 8-9 deg" NASA catalog weight=1. NASA catalog ID #401. ALPO/BAA weight=1
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.
On 1994 Apr 19 at UT 22:00 R. Knopp (Berlin, Germany) noticed a darkening of the interior of the crater Atlas. The ALPO/BAA weight=1.
Plato 1982 Nov 24 UT 22:00-23:30. K.P. MArshall (Columbia, 12" reflector, x100, x200, x480, seeing III, reasonably steady, but some turbulence. No craters could be seen on Plato's floor, despite observing conditions being acceptable. The floor was evenly toned, and the walls were sharply defined. By 23:10 there was a suspicion that the central craterlet was there, but he could not quite make it out, even with averted vision. 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.
On 1994 Apr 20 at UT 01:31 D. Darling (Sun Praire, WI, USA) found that Picard crater was surrounded by a dark nebulous patch - it was impossible to resolve detail inside this dark zone. The ALPO/BAA weight=1.
Alphonsus 1966 May 28 UT 23:00-01:00 Observed by Smith (England, 10" reflector) Birney (VA?, USA, 8" refactor + Moonblink) Corralitos Obs. (NM, USA, 24" reflector + Moonblink) "Red patches (Smith), Trident Moon Blink device suspected(?? log)earlier at 22:40. Birney observed at 2300-0100?, and gave indep. confirm? Corralitos did not confirm MB (however they report Gassendi-- misident. ?)" NASA catalog weight=5. NASA catalog ID #938. ALPO/BAA weight=4.
On 1992 Jun 09 at UT 18:52 G. Kolovos, Thessaloniki, 40.63111N, 22.9597W, height 28m, Greece) photographed two blue spots on the terminator region of the Moon in one of a series of Ektachrome film pictures. The rest of the Moon was a white-yellow colour. The ALPO/BAA weight=1.
On 1952 Jul 31 at UT 03:45-05:30 J.Carle (USA) and J. Supinger (USA, 6" reflector) observed the floor of Plato was almost blank, only two spots could be seen, despite other areas having plenty of detail. The ALPO/BAA weight=1.
SE of Ross D 1966 Oct 24 UT 03:17 Observed by Cross (Whittier, CA, USA, 19" reflector, x300, S=3-5, T=3-4) Ross D activity at level 5. ALPO/NAA weight=1 as it is not mentioned in the Cameron catalog.
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.
Linne 1867 Mar 15 UT 20:00? Observed by Dawes (England?) "Excessively minute black dot in middle of feature. A geom. fig. boarded & centered with black that formed, dissolved & formed again" NASA catalog weight=3 (average). NASA catalog ID #150.
On 1986 May 18 at UT 20:45-22:25 M. Mobberley (Suffolk, UK, seeing II- IV) found that the central craterlet of Plato was an ëasily seen "white splodge" although it was quite difficult to see when imaged with video. Foley and Cameron comment on IR sensitivity of the CCD camera used. The Cameron 2006 catalog ID=285 and the weight=1. The ALPO/BAA weight=1.
Alphonsus 1966 May 29 UT 21:45-22:45 Observed by Wise (England, 4.5" reflector, x125). and Corralitos Observatory (NM, USA). "Glint lasting 1.5s. (onset of Smith's anomaly? Specular reflection should last longer). Not confirmed by Corralitos MB, (however they report Gassendi? misident., or did they obs. another feature?). At UT 22:45 Smith and Brown (England, UK, 10" reflector) observed reddish patches in Alphonsus. Negative results from Brown though at 21:21Ut and 22:25UT). The Cameron 1978 catalog ID=939 and 940 and weight=4. The ALPO/BAA weight=3.
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. Only one exposure was taken. The photograph was checked by the Institute of Theoretical Astrophysics, University of Oslo. This report was received by the BAA Lunar Section.
127mm f/12 GoTo scope, x62-x154, seeing: best and transparency= 6) observed that an unoficially named mountain (Lambert Gamma or Mons Undest), near Lambert, had a "very strong glow", especially the part that was facing the line of the terminator and this was brighter than the side facing away. The No other object nearby was casting as much light, even Mons La Hire. The effect was seen for 40 minutes and the glow was present throughout. The ALPO/BAA weight=2.
Tycho 1998 Feb 06 UT 22:48-22:54 R. Braga (Corsica (MI), Italy, 102mm f8.8 refractor, x180, with diagonal, Wratten 23A, 80A and an OR5 filter, seeing II, Transparency good). Observer noticed that the floor darkened towards the NW (IAU), particularly with the blue Wratten 80A filter. The ALPO/BAA weight=2.
On 1989 Feb 16 at UT02:46-03:01 D. Darling (Sun Praire, WI, USA, 3" refractor, x140, seeing=6/10) found that the brightness of the rim of Proclus was 9.0 (normal?). The Cameron 2006 catalog ID=354 and the weight=0. The ALPO/BAA weight=1.
Gassendi 1967 Oct 13 UTC 19:17-20:00 Observers: Henshaw (Mansfield, UK, 8.5" reflector x112) and Corralitos Observator (Organ Pass, NM, USA, 24" reflector) "Phenomenon (brightening ?) nr. NW (ast. ?) lasting for 3s. Cont'd for 45m but nothing else unusual, (nr. Gass or in it?). Corralitos MB did not confirm." NASA catalog weight=3 (average). NASA catalog ID #1050.
Archimedes 1971 Aug 01 UT 22:00(?) (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.
Conon 1941 Feb 07 UT 03:00? Observed by Vaughon (Des Moines, Iowa, 3" reflector) "Faint bright spot on floor, no definite outline (??? reported 6th, but if local time 7th in UT)" NASA catalog weight=3 (average). NASA catalog ID #484.
SE of Ross D 1966 Oct 25 UT 03:46 Observed by Cross (Whittier, CA, USA, 19" reflector, x300, S=2-4 (sometimes 5), T=3-4) "Large bright area obscuring 1/2 of Ross D crater wall. Not present Oct 24" NASA catalog weight=3 (average). NASA catalog ID 986. Actually some activity was observed the fay before according to the original notes. ALPO/NAA weight=2.
Archimedes 1973 Jun 11 UTC 21:05-21:15 observed by Pasternak (53deg 20'N, 7deg 30'E, 75mm reflector) "Faint red area at the E of Archmedes, diminution from 21.10-21.15UT" - Hilbrecht and Kuveler, Earth, Moon & Planets, 30 (1984), p53-61
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.
Gassendi 1966 May 30 UT 20:32-20:59 Observed by Sartory (England, 8.5" reflector + filters) "Orange patch & obscuration -- detected by Eng. moon blink system. Color seen visually."NASA catalog weight=4 (good). NASA catalog ID #941.
On 1989 Feb 17 at UT00:55 D. Darling (Sun Praire, WI, USA, 12.5" reflector, x248) found that the brightness of the rim of Proclus was 9.0, the north west wall to be 9.5, the west wall to be 5.2, and the east wall 8.2 (normal?). The Cameron 2006 catalog ID=355 and the weight=1. The ALPO/BAA weight=2.
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. Note this is an ALPO observation and does not apear in the Cameron catalogs. ALPO/BAA weight=2.
On 1964 Jun 21 at UT 03:43-05:44 Harris, Cross and Helland (Whittier, CA, USA, 19" reflector) observed south of Ross D: "Moving dark area". The Cameron 1978 catalog ID=819 and weight=4. The ALPO/BAA weight=4.
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.
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.
Gassendi 1973 Jun 12 UT 20:50-21:15 observed by Baumeister (48.83N, 9.25E, 240mm reflector, T=2, S=3) "Bright point at the NNE slope of the central peak" - Hilbrecht and Kuveler, Earth, Moon & Planets, 30 (1984), p53-61. ALPO/BAA weight=1.
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 1825 Jan 01 UT17:00? an unknown Russian observer noticed a cloud in Mersenius.
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. That was the original location given for the A1 moonquake site, but it is located elsewhere now. Ancill. data given for 1970)." NASA catalog weight=1. NASA catalog ID #1273. ALPO/BAA weight=1.
Herodotus 1950 Mar 30 UT 19:00? Observed by Wilkins (Kent, UK, 15" reflector) "Transient c.p. (similar phen. to Bartlett's in later yrs.? see #532). NASA catalog weight=4 (good). NASA catalog ID #523. ALPO/BAA weight=3.
Herodotus 1956 Nov 15 UT 01:05-01:30 Observed by Bartlett (Baltimore, MD, USA, 3.5" reflector x100) "Pseudo c.p. clearly seen est. I=5.5, wratten filters showed it neutral to green, red, & yellow, but duller in blue. Floor est. 2deg, distinctly olive-green. Precise time at 0117 at col. 55.27deg" NASA catalog weight=4. NASA catalog ID #655. ALPO/BAA weight=3.
Aristarchus area 1967 Apr 21 UT 19:00-21:20 Observed by Darnella (Copenhagen, Denmark, 3.5" refractor, S=1-2), Farrant (Cambridge, England, 8" reflector, x160), Corralitos Observatory (Organ Pass, NM, USA, 24" reflector with Moonblink) "On exterior wall of Aris., 3 pts. in Cobra Head & banks of valley were star-like & glowing; & Herod. were red. Farrant could not bring hill N. of Herod. into focus. He says color was deep red-orange & steady for 3 min. Started at 1915h (1916-1925h seeing was too bad) (indep. confirm.). Suspected next nite but bad seeing. Not confirmed by Corralitos MB." NASA catalog weight=5. NASA catalog ID #1030. ALPO/BAA weight=4.
On 1993 Jun 02 at Ut 04:30-05:45 S. Beaumont (Cambridge, UK) saw that the shadow of the Cobra's Head in Schroter's Valley was lighter and more diffuse seen at user defined locations of C or B rim (these were black versus medium gray for Cobra's Head). The TLP had vanished by 05:45UT. The Cameron 2006 catalog ID=462 and weight=3. The ALPO/BAA weight=1 because the date or time is wrong.
On 1984 Nov 05 at UT18:00 Marshall (England) noted that there was no normal brightening on the floor just next to the southern most craterlet. The Cameron 2006 catalog ID=251 and the weight=2. The ALPO/BAA weight=1.
On 1994 Apr 23 at UT02:41 D. Fryback (Madison, WI, USA) observed a starlike flash in Alphonsus crater. The ALPO/BAA weight=2.
On 2004 May 01 at UT 22:20 R. Lena (GLR, Italy) received an image from one of his observers showing possible blue colour in Aristarchus crater and part of the ray towards Herodotus. The ALPO/BAA weight=1.
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 effect was not linked to atmospheric turbulence. Also projected image of bands beyond the crater W. wall were repeatedly noted. The observer broke away from observing at 20:45UT to make a telephonealert call. At 20:55UT they noted that the area between Vallis Schroteri and Herodotus seemed very light/bright, also the E. exterior of the crater wall of Herodotus. From 21:01-21:11 A slight blueness was seen to extend from the NE corner of Aristarchus, along the exterior rim, acrossand beyond Herodotus to the SW. A tgorough search was made of many bright areas, both near the terminator and to the E., but no blueness could be detected elsewhere. A slight orange hue was noted along the E. limb of theMoon (Spurious colour). From 21:18;22:30 Aristarchus seemed normal again, and likewise the head of Vallis Schoteri too. The observer was clouded out from 22:30-23:15and from 23:15-01:30 the seeing was so appaling that no colour or projection of the bands could be seen. A Moon Blink was used during the session, but no colour was detected in this? Another observer, R.W.
