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.

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=2.
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.
On 1981 Aug 11 at UT21:05-21:36 G. North (England, seeing=poor) detected, in green light, a darkening on the floor of Plato. This effect was not seen elsewhere. J-H Robinson (Teighmouth, Devon, UK) detected on the SSE rim (inner and beyond) a triangle that appeared hazy in a wide range of filters at 21:05UT. However at 21:36UT it was only hazy in green and blue light. No similar effect was seen elsewhere. The Cameron 2006 catalog ID=150 and weight=5. The ALPO/BAA weight=3.
On 1978 Oct 23 observing period: UT22:00-22:40 A.C. Cook (Frimley, Surrey, UK, 6" reflector, x144, 6mm Ortho eyepiece, seeing IV, red and blue filters used) saw at 22:10 a secctor on thwe western floor to be mainly bright in the red. The surface was bumpy here. The observer at the time commented that this was probably not a TLP, but no precise explanation given. ALPO/BAA weight=1.
Torricelli B 1995 Apr 11 UTC 20:15 Observed by North (UK). "Colour moonblink reaction, and crater dull". BAA Lunar Section report. ALP\BAA weight=3.
On 2017 Feb 08 UT 01:45 A.Martini Jr (10" Schmidt-Cassegrain with ASI 120 MC camera +IR filter, Gain 40, Gamma 36, exposure 0.003 sec) saw on a computer monitor screen a flash to far to the west of Herodotus and Aristarchus at the location 54.53W, 23.5N. It had a duration of 0.5 sec and on a brightness scale of 0 = night side of the Moon to 10 = Aristarchus, ranked 7. Unfortunately they were not recording at the time. As there was no confirmation observation and it could be a cosmic ray air shower detection, the ALPO/BAA weight=1
In 1934 Feb 25 at UT 18:30 Rawstron (USA?, 4" refractor, x250, S=6/12) observed in Pico B: "A large patch of haze appeared & drifted off across the mare in same direction as haze from Pico (white patch). It was obs. on 20 other occasions. Drawing". The Cameron 1978 catalog ID= 410 and weight=3. 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.
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 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 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.
Gassindi 1966 Oct 25 UTC 22:30-23:10 Observed by Moore and Moseley (Armagh, Northern Ireland, 10" refractor) and Sartory (England, 8.5" ? reflector) "2 faint blinks (Eng.) on NW (IAU ?) wall. (Indep. confirm.?). NASA catalog weight=5. NASA catalog ID #987. ALPO/BAA weight=4.
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.
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 UTC 20:00? Observed by Trouvelot (Meudon, France) "Luminous light like a luminous cable or shining wall". NASA catalog weight=3. NASA catalog ID #217.
Herodotus 1965 Jun 11 UTC 21:35-21:40 Observed by Porta, Garau (Mallorca, Baleares, 4" refractor x250) "Red glow in crater at 2140, then clouds stopped obs. After clouds, floor was abnormal rose color" NASA catalog weight=5. NASA catalog ID #879. ALPO/BAA weight=4.
On 1978 Mar 21 at UT 20:57 an Unknown observer observed a TLP in Aristarchus crater. The details for this report are still being looked up in the archives. In view of the uncertain details this TLP has been given an ALPO/BAA weight of 1.
On 1965 Jun 12 at UT > 00:00 an unknown observer (Porta?) reported that the area of Herodotus and the Cobra Head expanded and the colour went to rose. The next night the floor was normal. In filters, phenomenon accentuated in orange. The cameron 1978 catalog ID=880 and weight=3. The ALPO/BAA weight=2.
On 1975 Apr 23 at UT 20:30 J-H Robinson (Teighmouth, Devon, UK, 260mm reflector, x200). Observer was observing since 20:30UT, at 21:00UT though they noticed red on the outside south wall of Aristarchus, a hazy ill defined area that was larger in a red filter than in blue filter, and outside east wall was bright in red. At 21:08UT the outside west wall of Aristarchus no longer gave a colour blink reaction, and at 21:22UT the colour blink on the southern end of the crater ceased, but the image blur remained (in both red and blue filters) despite the rest of the crater being sharp in detail. Observations ceased at UT 21:35 because the blurring at the southern end seemed to be normal and this was confirmed when checked with photographic atlases. Other craters such as Proclus, Pickering, Tycho, Gassendi, Copernicus, Alphonsus, Plato, Menelaus, Manilius, Linne and Theophilus, showed no colour blink reactions. However Picard had a red bright blink from 20:30-20:40 and the permanant blink on the N. Floor of Fracastorius was detectable. Also Plato floor shadings were clearer in red than in blue - intermittently. This is a BAA lunar section observation. No estimation of transparency or seeing is given, nor any comment on whether spurious colour was seen in any craters visually. ALPO/BAA weight=1.
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.
On 1987 Sep 05 at 20:55UT A.C. 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.
On 1980 Sep 22 at UT05:00? D. Louderback (South Bend, WA, USA, 8" reflector, x140 and 2.5" refractor) observed in Promitorium Agarum that one of his pre-designated points, called "A", through to "C and "D" was at least 5 brightness points brighter in red than in blue light. The reverse was true on Sep 25th. Tonight the red seemed to be on a narrow strip on the western edge. The Cameron 2006 catalog ID=109 and the weight=3. The ALPO/BAA weight=3.
On 1985 Sep 27 at UT 20:55 M. Mobberley (Suffolk, UK) found that the brightness of Torricelli B varied and starlike points seen in the crater. There is no Cameron 2006 catalog entry for this TLP report. The ALPO/BAA weight=2.

Observations terminated by hazy cloud drifting over Moon. Observer remarked that it looked like chromatic aberation, but telescope was a reflector and no colour was seen elswehere on the Moon. Cook (Frimley, Surrey, UK) 19:48-19:55 noted red on E. rim exterior and on SE part of central peak, and blue on N. rim - strongly suspected spurious colour". ALPO/BAA weight=1.
1975 Apr 18?? UT16:05-23:44 R. Billington (6cm refractor, x35 and x56). TLP faded at 17:50 but prominent again later. Intensity 8 at 16:05, 6.5 at 17:50 and 8 at 23:44. This is a BAA Lunar Section report.

On 1963 Dec 30 at UT11:00 many observers reported seeing a red glow on the North East (IAU?) limb of the Moon. This was also captured on a photograph. Cameron suggests eclipse geometry as an explanation. Thye Cameron 1978 catalog ID=792 and weight=1. The ALPO/BAA weight=1.
On 2000 Jan 21 UT04:40 G. Emersen (Golden, CO, USA, 30cm focal length lens with Wratten 25 ref filter) took 43 CCD images of the eclipse of the Moon and on one of them at 04:40UT (exposure 0.3 sec) a relatively bright spot appeared in the southern part of Mare Fecunditatis. The spot looks sharper than the rest of the Moon and so might be a cosmic ray? CCD images taken from Washington D.C. by A.C. Cook at this time, do not show this spot, however exposures were at intervals of 0.25 sec and so might have missed this spot if it happened during image readout. The ALPO/BAA weight=1.
On 1901? Nov 25/25 at 23:00UT Besanceas (France?) observed: "During lun. ecl. (mid-ecl. at 0118 on 26th) a bright area seen on moon. Another(?) obser. saw an obj. like a fiery comet leave the moon! (Date given by Midllehurst was 1900 but must be wrong-not FM then. FM in 1900 but no ecl. Partial ecl. on 10/27/01 at 0315. Ref. by M is wrong = 157)". The Cameron 1978 catalog ID=310 and weight=1. The ALPO/BAA weight=1.
On 1848 at UT 21:00 Rankin and Chevallier (France?): Luminous pts. seen during an eclipse. Cameron ays that year 1847 given by Middlehurst must be wrong as age is 2.7 days for this date in 1847 and could not be 18- 19 as in Middlehurst because eclipse is on the 19th at 21h (mid) in 1948. aux. data here are for 1848. At 21:12 Forster (England) and Bruges (France) observed rapid changes in red colour. The Cameron 1978 catalog ID=126 and 127 and the weight=5. The ALPO/BAA weight=3.

On 1979 Sep 09 at UT08:00-08:15 D. Darling (Sun Praire, WI, USA, 12.5" reflector, x75 and photography used, seeing 4/10 and the Moon's altitude was 45deg) photographed Romer crater and recorded two adjacent bright cigar shaped objects - these were the same size as an observation made in 1987. Darling believes that these are ridges. Cameron comments that in LO-IV 192-3,2 a ridge is revealed on the inside wall that matches the description. Cameron 2006 catalog ID=66 and weight=2. ALPO/BAA weight=1.
On 1982 Jul 09 at UT 01:05-01:25 P. Moore (Selsey, UK, 12.5"? reflector, seeing III) found that Aristarchus was very bright and slightly blue. Cameron comments that Moore's eyesight is not very blue sensitive. The Cameron 2006 catalog ID=175 and weight= 4. The ALPO/BAA weight=2.
On 1982 Jul 09 at UT01:05-01:25 P. Moore (Selsey, UK, 12.5" reflector, seeing=III) found that Grimaldi A was the 2nd brightest feature on the Moon, and that there was colour detected with a Moon blink device on the floor of Grimaldi.

On 1974 Jun 12 at UT0256 an unknown observer noted a dark blob on the northern edge of the floor of Pitatus crater.
On 1944 Aug 12 at UT 04:00 H.P. Wilkins (Kent, UK, 8.52" reflector) observed that central craterlet in Plato was unusually bright and shows up as a bright white spot on his sketch - though this might have been artistic license in his sketch. His written notes refer to the unusual lack of a rim (especially the northern part) to this craterlet. The ALPO/BAA weight=2.
Briggs A 1980 Feb 11 UT 06:30-07:00 Observed bt Butler_FC (Brixton, UK, 22cm Newtonian reflector, x64, x104, seeing IV). Found Briggs A to be brownish in colour at x64, however the colour vanished at 06:55 when x104 was used. Switching back to x64 the colour was still there but fainter. The colour fade may have been due to day light glare encroaching? Could not see this effect anywhere else on the Moon but did detect what he regarded as a permanent coloured spot (yellow) between Cruger and Grimaldi. ALPO/BAA weight=1.
Aristarchus 1976 Oct 18 UT 07:42 Observed by Bartlett (Baltimore, MD, USA, 4.5" reflector and 3" refractor, S=3, T=5) "Inner E. wall 6 deg with very large EWBS at 8deg. No viol. color anywhere & floor was gray at 4 deg (very low). C.p. is only 8 deg. At base of c.p. between peak & advancing shadow a very faint but definite red glow was seen. It was also seen later in the 3" refr. Was confined to W.base of peak & no color on E. base tho. carefully searched for. This red glow was unique in his experience of 28 yrs. His obs. thru. col. 223deg saw nothing more unusual." Cameron 1978 catalog weight=4 and ID #1455.
Herodotus 1969 Aug 09 UTC 03:00-04:03 Observed by Gomez (Sabadell, Spain) desribed in NASA catalog as: "Bright point on SE wall at 0300h, gone at 0322h.

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.
