On 1975 Apr 19 UT 21:09 P. Foley (Kent, UK), detected blue in Plato on east. Fiton at UT20:45 found blue along the south wall at the east (IAU?) end, which was very bright white. Blueness extended towards the large landslip at the east of the formation. Immediately north of the landslip, where the bright wall curves first westwards, then again northwards, red could be faintly detected, folloowed by a very faint blue. All other parts of the formation were normal. Examination with a Moon blink device revealed no colour blink. J-H Robinson also found blue, with red on the west wall (exterior?). By 21:30UT Fitton found Plato to be normal and so was Proclus, though he did find Epigenes (bright cresecent of east wall only) slightly blue to the N.W and red to the S.E. Mare Crisium was normal. Prominent spurious colour seen on Venus, but it was low in the sky, with blue to the north and red to the south. However J.H. Reading, managed to see the north east floor blurred and slightly blue from 22:45-23:00UT. These reports are BAA observation. The ALPO/BAA weight=2.

On 1980 Oct 17 at UT18:40-19:10 G. Blair (Weir, Renfrewshire, Scotland, UK, 22cm reflector, seeing II, transparency excellent, no spurious colour) noticed at 18:40UT that the bright central peak of Alphonsus was elongated. At 18:41UT, at higher power, the central peak separated from a bright point of light, intensity about that of a 6th magnitude star. at 18:43UT a filter check was made of the suspect point and surrounding regions - slightly nrighter in red. At 18:50UT intensity of bright point reduced to equivalent of 4th magnitude star. Noted that Earthshine was the brightest that he had ever seen it. At 19:03 UT losing the Moon behind a chimney. UT 19:10 brief appearance, bright point still seen at 4th magnitude. 19:27UT the Moon disappears again. 20:15UT reappearance of the Moon and Alphonsus appeared normal. The ALPO/BAA weight=2. This is a BAA Lunar section observation.
Tycho 1940 Dec 09 UTC 04:00? Observer Barcroft (Madera, CA, USA). The NASA catalog states: "Some luminosity on W. rim of outer slope". 6" reflector used. NASA TLP catalog assigns a weight of 3 (average). NASA catalog TLP ID No. #481.
Plato 1966 Jun 27 UT 21:40-21:55 Observed by Robinson (Teignmouth, England, 10.5" reflector) and Sartory (England, 8.5" reflector + Moon blink) "Color (red?) on SE wall detected by Eng. moon blink sys. (confirm)." NASA catalog weight=5 (very high). NASA catalog ID 949.

Detail best seen in blue & green filters. Dillon found halo much lighter than usual, with sharp boundary washed out. Halo was darker thru blue filter, indicating red when it's normally bluisg-green. Next nite it was normal. Worsening weather stopped obs. (confirmation. Apollo 11 watch)." NASA catalog weight=5 (very good). NASA catalog ID #1185.
On 1990 Apr 05 at UT 00:43-01:46 D. Darling (Sun Praire, WI, USA, 3" refractor, x90) observed that Bullialdus (the crater was in shadow) was pink in colour on the edge of its wall. The effect lasted from 01:15- 01:44UT and he could discern the terrace on the western wall. Comparisons were made to Tycho and Copernicus - all of which were normal. The Cameron 2006 catalog ID=399 and the weight=3. The ALPO/BAA weight=3.
On 1992 May 11 at UT 20:20-21:00 R. Amendsensvej (Esbjerj, Denmark, 10" reflector, x333) noted that Copernicus had "almost no disturbance. Flash was seen between 2236:30 & 2236:40. Thus 10S". The Cameron 1978 catalog ID=444 and weight=1. The ALPO/BAA weight=2.
Bullialdus 1980 Oct 18 UT 20:15-20:25 Observed bt Amery (Reading, England, 10" reflector) "Colour blink reaction in English Moon Blink Device" BAA Lunar Section report. Cameron suggsets that this might be a permanent coloured blink area. Cameron 2006 catalog ID=115 and weight=3. ALPO/BAA weight=3.
Fracastorius 1980 Oct 18 UT 17:55-18:15 Observed by Robinson (Devon, England, 260mm Newtonian, Seeing III, Transparency poor) "Colour blink reaction in English Moon Blink Device - inner wall brighter in red than in blue light, despite other features appearing normal. BAA Lunar Section report. Cameron 2006 catalog ID=115 and weight=3. ALPO/BAA weight=2.

Cameron 2006 catalog ID=115 and weight=3. ALPO/BAA weight=2.
Manilius 1972 May 22 UTC 20:10-20:40 observed by Kern (48deg 45'N, 8deg 45'E, 60mm refractor) "The SW inner wall became brighter at times" - Hilbrecht and Kuveler, Earth, Moon & Planets, 30 (1984), p53-61.
La Hire 1922 Nov 28 UT 22:00? Observer Wilkins (England). NASA catalog states: "Shadow cut thru by white streak (real LTP?. Pickering's atlas shows same phase & col. & shadow is all dark; elong. in peaks are N-S not E-W)" 15" reflectore used. NASA Catalog assigns a weight of 4. NASA catalog TLP ID No. # 388. ALPO/BAA weight=2.
On 2009 Apr 04 at UT 20:30-20:45 C. Brook (Plymouth, UK) observed a slight pinkish mottling on the floor of Plato. The effect was no longer visible after 20:45UT. A telephone alert was put out to M. Cook and G. North. The former saw no colour, but this was after the event finished. The latter observer reported cloudy conditions. A.Cook was probably observing at the same time as C. Brook, via a couple of remotely controlled telescopes in Aberystwyth. The results (time lapse imagery through narrow band filters) will be examined at a later date.
Plato 1972 Mar 24/25 UT 20:38-00:00 Observed by M.Burton (UK, 13.5" reflector, seeing IV-V, Transparency Fair, x180) UT20:38- 20:45 floor was darker in a red filter than in a blue. UT20:47- 20:56 JS Burgess (seeing 2/5, x200, with and without filters) found everything normal (with and without filters). UT20:00- 20:07 and 21:30-21:35 A.J. Beddoes found everything normal (with and without filters). However at 23:10 L.Fitton suspected that the E (IAU?) floor of Plato had a red-brown cast, but could not be quite sure. UT23:54-00:00 M.Burton, detected the floor was darker in red than in blue light. Burton did not detect any colour without the use of filters on either of the two occasions that he detecetd a blink. In view of the fact that two observers did not detect anything, albeit not concurrently with the TLP reports, this TLP is being given an ALPO/BAA weight of 1.
On 1983 Jul 20 at UT 18:50-22:40 P.W. Foley (Kent, UK, 12"reflector, seeing II-III) noted that the south wall of Plato at the 11 o'clock position, at the location of a cleft, was fuzzy on either side of the cleft. There was also a deep red colour along the cleft and the outside wall. The colour had gone by 22:40 though. All other parts of the rim of Plato were clear and distinct. M. Cook (Frimley, UK, seeing III) sketched some obscurations at 22:03UT. At 22:08UT the red colour reduced to a red line and vanished by 22:37. The south wall obscuration varied in size and there was a possible obscuration at the 7 o'clock position. J. Cook (Frimley, UK, seeing II-III) confirmed Foley's and M.Cook's observations. Detail inside the crater was sharp, but colour oppoiste to what is usual. Price (Camberley, UK, seeing IV-V) a few km away had atmospheric ripples affecting his observations. At 21:36UT G. North described the south wall as odd in appearance and the terrain south of this was lacking in detail - this was odd because elsewhere Plato was nice and sharp. At 21:45UT though the north section of the crater was a hazy red. The cameron 206 catalog ID=224 and the weight=5. The ALPO/BAA weight=3.
Sinus Iridum 2004 May 29 UT 20:44 Observed by Clementelli (Rome, Italy, 102mm diameter Vixen refractor 80-160x, sky conditions: clear, no wind) "A blue/violet streak, lasting ~10 minutes was seen on the floor of Sinus Iridum between crater Bianchini and Promontorium Heraclides. The suspect TLP mybe an effect of instrumental achromatic aberration, but there is the small possibility that the effect was real." A UAI observational report. The ALPO/BAA weight=1.
On 1983 Aug 19 at UT 07:15-07:30 D. Louderback (South Bend, WA, USA, 3" refractor, x150) found that the direct sunlit side of Mons Piton mountain (E) was brighter than (his designated) points C and D and this happened at the same time as some "blurring"at 07:15UT. The darker side, between C, A and B were not so dark through a red filter as through a blue filter (this was the opposite of what had been seen before at a high sun angle). Louderback suspects that there had been a colour change since he last observed. He also noted that in red light the whole lunar disk appeared fuzzy and out of focus. Louderback noted a 1 sec brightness on the east slope and the whole mountain sharp in blue light. The Moon's altitude was low though. Brightness measurements were 4 in blue light and >= 4.6 in red light and "so illdefined almost blended into plain". Cameon commnets that a telescope colour/focussing issue may have been at work here! The Cameron 2006 catalog ID=226 and weight=4. The ALPO/BAA weight=1.
On 1989 Jul 14 at UT 03:28 D. Darling (Sun Praire, WI, USA) found a darkening in the crater Proclus, but the shadow seen by Cook and Moore, from a few hours earlier was not seen. The Cameron 2006 catalog ID=371 and the weight=2. The ALPO/BAA weight=1.
Archimedes 1979 Oct 01 UT 20:57-21:00 Observed by Cook (Frimley, UK, 13mm Monocentric + Barlow eyepiece, Seeing IV, transparency: thin cloud) "Red seen on east, blue seen on west - almost certainly spurious colour".
Bullialdus 1979 Oct 01 UT 21:04-21:07 Observed by Cook (Frimley, UK, 13mm Monocentric + Barlow eyepiece, Seeing IV, transparency: thin cloud) "Red seen on east, blue seen on west - almost certainly spurious colour". ALPO/BAA weight=1.
Alphonsus 1959 Feb 18 UT 21:00? Observed by hole (Brighton, England, 24" reflector) "Red patch (Moore in Survey of the Moon says Jan. '59). Moore says, Warner, in Eng. saw it bright red in an 18-in refr. Hedervari & Botha in Hungary saw red patch & several in US (indep. confirm. ?)" NASA catalog weight=5. NASA catalog ID #714. ALPO/BAA weight=5.
On 1991 Feb 25 at UT 01:26-01:49 D. Darling (Sun Praire, WI, USA, 12.5" reflector, x248, seeing=10/1, transparency=good) found Gassendi's western rim to be bright in red and diffuse in blue light. A sketch was provided. The Cameron 2006 catalog ID=420 and the weight=4. The ALPO/BAA weight=2.
Aristarchus 1967 May 20 UTC 20:15 Observed by Darnella (Copenhagen, Denmark, 3.5?" refractor) "Red spots on S.rim. Moon was low." NASA catalog weight=1 (very low). NASA catalog ID #1036.
On 1967 May 20 at UT 21:05-21:20 Kelsey (Riverside, CA, 8" reflector, x300) using an English Moonblink device found colour on the south west part of the floor. Note that for the times given by Cameron, the Moon was below the horizon from California - so possibly these are local times and these times need to be correctly converted into UT? The Cameron 1978 catalog ID=1037 and weight=3. The ALPO/BAA weight=1.
On 1980 Dec 18 at UT20:46-23:58 A.C. Cook (Frimley, UK, 12" reflector, 40-250x, S=IV and transparency good) found the north west wall to be brighter in red than in blue light, however the effect faded during 21:29-21:41UT and was gone by 22:40UT. There was however spurious colour on the north west wall. M. Cook (Frimley, UK) found the central peak to be both bright and diffuse, and brighter in red than in blue light during 20:52-20:57UT, however at "22:53-23:58 c.p. very bright & previous area decreased in size. No detail in white or red, just visible in blue. Sketch (J. Cook) Orange out on NW rim & on NW side of c.p. Similar effects seen on other craters. (madej) c.p. & W. rim wall very sharp. c.p. disappears in yellow but still seen in purple. (pedler) c.p. > red than blue but no obstruction. W wall interior dusky, darker in blue." A.C. Cook's photo depicts the central peak as very bright. Cameron 2006 catalog TLP ID=120 and weight=5. ALPO/BAA weight=2.
Aristarchus 1989 Jul 15 UT 02:00-04:20 Observed by Manske, Weier, Curtis, Keyes, Yanna, Norman, Knutson, Sullivan, Eichman and Radi (Carl Fosmark Jr. Memorial Observatory, Madison, WI, USA, SCT C11) "Manske initially observed a reddish tinge on the SE rim of Aristarchus. The colour was present in different eyepieces. Two other pinkish tinge areas were seen on the SE and NE rims. 4 of the observers did not see colour. Independent confirmation was made by Don Spain (KY) and Smith in LA. Full details can be found on the following web site: http://www.ltpresearch.org/ltpreports/LTP19890715.htm " An ALPO report.
On 1992 May 13 at UT 20:16-21:29 several observers reported a TLP in Plato mostly concerning the visibility of floor craterlets, however observer seeing varied from III-V. North (UK, 18.25" reflector) reported "Colouration and floor craterlets very prominent. Seeing Antoniadi V, Transparancy Poor.". Foley (Kent, UK, 12" reflector seeing=III-IV) found the floor to be bright and in the better moment of seeing detected floor craterlets. The WNW spot was misty some of the time. Moore (Selsey, UK, 15" reflector, seeing V) had very poor seing conditions. J.D. Cook and M.C. Cook (Frimley, UK, 3.6" reflector, seeing II-III) used a CCD camera at 22:11 UT. The Cameron 2006 catalog ID=445 and the weight=5. The ALPO/BAA weight=2.
Aristarchus 1969 Jul 26 UT 02:15-03:00 Observed by Jose L. da Silva (Rio de Janeiro, Brazil, 13" refractor) "Unusual brightness whole time in center of W. inner slope; rest of crater & Herodotus appeared normal. SW to NW inner slope had pronounced brightness. Aris. still in dark! Apollo 11 watch)." NASA catalog weight=3. NASA catalog ID=1186. ALPO/BAA weight=1.
On 1983 Jul 21 at UT 21:02-23:18 P.W. Foley (Kent, UK, 12" reflector, seeing=III) found the region around the cleft on the souther rim to be out of focus - however atmospheric conditions were turbulent until 23:18UT. An unsual dark triangular region (long base against rim) was seen to extend from the inner rim at 12 o'clock onto the floor for 13- 16km. The crater had lots of detail elsewhere. M. Cook (Frimley, UK) found the south east to soth west to be obscured again, but not as badly as she had seen on the 20th July. J. Cook (Frimley, UK) found the dark region had 2 white bands on the side and the south west wall was blurred like it was on the 20th July - this time tough colour was not present. There were also two light patches on the floor. Mosely (Coventry, UK) observed the south wall at x120 and found the wall out of focus at the 11 o'clock location. Through a yellow filter he saw a "white mistiness: on the top of the southern rim and only the south east cleft could be seen (no colour). By 22:40-23:00 the effect had cleared up. No dark triangular patch was seen. When Marshall (Surrey, UK) observed (22:30-03:00) nothing unsual was seen, though a sketch provided shows a light patch on the floor located at 11 o'clock. All observations, made by all observers had some atmospheric turbulence, however trsnparency was good. The Cameron 2006 catalog ID=225 and the weight=5. The ALPO/BAA weight=3.
Aristarchus 1880 Jan 23 UT 20:00? Observed by Trouvelot (Meudon, France) "Luminous light like a luminous cable or shining wall". NASA catalog weight=3. NASA catalog ID #217. ALPO/BAA weight=2.
Aristarchus 1969 Jul 26 UT 02:30-03:00 Observed by Mauro Migon (19" refractor), Julio Nogueira (10" refractor), Wairy Cardoso (13" refractor) all from Rio de Janeiro, Brazil "Crater was gray-bluish, different from any other region & unusually bright. Cardoso saw brightening, used blue, red, green & neutral filters. Apollo 11 watch, Jose da Silva says obs. no good, obs. was inexperienced. However it is similar to many other obs. with much experience)." NASA catalog weight=2. NASA catalog ID No. 1187. ALPO/BAA weight=1.
On 1992 May 13 at UT 22:30 R. Turner (Wolverhampton, UK, 3.6" reftactor, x50) noticed that there was a white spot on the WSW rim that he had not seen earlier. The Cameron 2006 catalog ID=445 and weight=5. ALPO/BAA weight=1.
Aristarchus 1971 Mar 08 23:00-23:10 Observed by Lyttle (Northern Ireland, 6" reflector, x98) "Suspicion of white spot W of N-S radial band, slightly brighter than wall. Diam. @5-6km. Area affected by temp. ?Term. passed over it just 5h before. Gradual decline in brightness over the 10m period." NASA catalog weight=1 (very low). NASA catalog ID 1288.
On 1963 Nov 28 at UT 00:30-01:45 Barr, Greenacre, Hall and Dungan (Flagstaff, AZ, USA, 24" refractor, and 69" reflector) observed pink on the outer SW rim and a red spot towards the S of this. A red spot was seen on the eastern side of Vallis Schroteri but only by Barr and Dungan. Other features checked for atmospheric spectral dispersion and chromatic aberation - but the colours in Aristarchus were not due to these. Smaller 12" scope checked but no effects seen - presumably due to resolution and image contrast issues? Pink on the SW rim may have been seen in a 69" scope by Boyce and Ford. ALPO/BAA weight=4.

Gassendi 1987 Sep 05 UT 20:25 Observed by Moore (Selsey, Sussex, UK, Antoniadi III seeing, 12.5" reflector) "Intensely bright craterlet south of central peak, surrounded by a luminous nimbus. Foley (Kent, UK, 12" reflector)onfirmed the crater was highly luminous at 21:20, and surrounded by a blue halo that had a darker blue band within it. This craterlet faded over time, and by 21:20 Moore considered that it was no longer prominent, by 21:22 Foley confirmed the reduced brilliance, and by 21:30 Moore considered it to be perfectly normal. Moore considers the nimbus effect to be normal. The Cameron 2006 catalog ID= 306 and weight=5. The ALPO/BAA catalog weight=3.

Cook (Frimley, UK, 90mm questar telescope, x130, seeing III-IV, Moon 16 deg in altitude) observed a dusky dark gray area just north of Herodotus and just south of the Cobra Head. The interior shadow on the east of Herodotus by comparison wad black and distinct. No change was seen when viewed through a rotated polaroid filter. Apparently D. Darling (Sun Praire, WI, USA) was observing at the same time but had better observing conditions and could see detail in this region, suggesting that it was not a TLP. There is no Cameron entry for this report. The ALPO/BAA weight=1.

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.

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.

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.
"Proclus D. (Bartlett's designation) appeared as a dark spot, conformable to lts appear. at col. 111.15 deg in '55. Proc. A (Bartlett's designation) completely invisible the ordinarily easy to see.

Apparently Chapman (Kent, UK) detected it easily. At 01:33UT the colour was barely visible. No TLP alert was issued because the souther edge of Mons Pico also exhibited a hint of colour, and anyway the seeing conditions were poor. Despite this no other features revealed colour.

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.
