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.

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).

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.
Gassendi. 2023 May 02 UT 01:35-02:23. J. Albert (Lake Worth, FL, USA - ALPO. 8” SCT via a 9mm ortho eyepiece. Transparency magnitude 3 and seeing was 7/10) checked the crater without filters as well as comparing with W25 red and W44A blue filters using 226x. He saw no color on the SW part of the crater floor or on the NW wall. Using the filters, however, he did note that the high peak on the S wall was brighter in blue than red. He tried this filter blink a number of times because he had never seen this before in Gassendi, but the result was the same each time. A colour image was taken earlier at 01:21UT but shows not colour on S wall as it was saturated. ALPO/BAA weight=2.
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.
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.
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=3.
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.
Plato 1873 Nov 01 UTC 20:00? Observed by Pratt (England?) "Unusual Appearance". NASA catalog weight=1 (very low). NASA catalog ID #182. ALPO/BAA weight=1.

On 1976 Nov 03 at UT20:00-21:40 P.W. Foley (Kent, UK) reported a TLP in Gassendi - some obsevers detected colour, others did not. P. Moore did not notice anything unsual earlier at 18:50-19:00, though his seeing was IV-V. Nor did he see anything unsual from 21:53-00:20, but seeing was still IV-V. D. Jewitt, observing 20:34-21:25 and 22:55-23:20 also reported nothing unusual. Amery (Reading, UK, 25cm reflector, x300) did however notice a small reddish spot to west of central ridge, but by 20:30UT the colour was less obvious, but the spot was back again at 20:45, but not easily seen at 21:00 and gone completely by 21:45UT. N.Bryant (Ilfracombe, UK, 25.4cm reflector, x260), observed 3 red patches on the floor between 20:54 and 21:31UT. A BAA Lunar Section report. ALPO/BAA weight=3.

On 1980 Aug 22 at 02:15-21:29UT J-H Robinson (Teighmouth, Devon, UK, 12" reflector, x200, seeing=II) noticed in the area south east of Manilius that it was brighter in red light than in blue light at 20:15UT whereas 1 minute later it was the same brightness in each filter. The effect reappeared at 20:21UT and was particularly strong at 20:32UT. Foley (Kent, UK) verified this at 21:01UT - the blink area was of high reflectivity in white light and was bright in red at 21:15UT, thougjh the south east area stopped giving a colour reaction at 21:25UT. Madej (Huddersfield) found Manilius B to be norm al at 23:52UT however at 23:55UT it was surrounded by a transient white ring that varied in visibility in an irregular way. Foley found Manilius B had a vivid blue interior and in blue light the ring was black. and not at all seen in red or white light. The CED brightness measurement varied from 1.9 to 2.4. All other regions observed were normal in brightness. Violet was seen on the west wall of Aristarchus though. M.Price (Camberley, UK) found a possible blink in Manilius B but was observing under poor seeing conditions. Cameron 2006 catalog ID=105 and weight=5. ALPO/BAA weight=4.
Gassendi 1968 Oct 03/04 UT 19:30-19:50 & 00:20-01:40 Observed by Rawlings (Aylesbury, UK, 6" reflector low magnification) and by Moore (Selsey, Sussex, UK, 12.5" reflector, x360) "Slight blink (Eng.) arcuate in shape, N. of c.p.

On 1964 Jun 21 at UT 21:18 Lipskii and Pospergelis (Shternberg State Ast. Institute, AZI-2" reflector (Cass.) observed Aristarchus: "Polarization meas. with electron polarimeter. Plane of polariz. rotated 2deg fr. the adjacent areas. They interpret it as some scattering medium over the crater. (Source gave date as 6/31/64, misprint =21st?)". The Cameron 1978 catalog ID=820 and weight=5. The ALPO/BAA weight=4.
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.

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.

Floor there was distinctly yellow-brown. Had never seen browns or yellows before June 25, 1964. (seeing true color of ground?)."NASA catalog weight=4 (good). NASA catalog ID #835.
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 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.
Aristarchus 1968 Apr 11 UTC 22:00? Observed by Farrant (Cambridge, England, 8" reflector, Seeing Antonidi I (very good)) "Crater had on NE (ast. ?) wall a very pale blue color & opposite wall a pale red. No other crater showed color.

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 1977 Apr 02 at UT22:00-00:00 L. Fitton (Shaw, Lancashire, UK, 8.5" reflector, x200, Wratten 25 and 44A filters, seeing II-III, transparency, good) noticed in Aristarchus, blue to the north west (IAU?) internal wall, also blue observed in other small bright objects against dark backgrounds. Lunar rotational axis and optical normal related such that the normal runs NW-SE (IAU?) through these features. Observer deduced that the coliur was obviously spurious and no blink was seen in any feature. The blue disappeared as the lunar altitude increased and no blue seen by 00:00UT. This is a BAA lunar section observation. The ALPO/BAA weight=1.
On 1992 Jan 18 at UT 22:34-23:48 A.C. Cook (Frimley, UK, 8" reflector, seeing=III) was able to see 4 craterlets and two rays on the floor of Plato. This was suprising because Moore, using a larger telescope and magnification, was unable to see any detail here on 1991 Dec 12th at 02:10 - according to Cameron. The Cameron 2006 catalog ID=438 and the weight=2. The ALPO/BAA weight=1.

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 1927 Dec 08 at 20:00 Bogdanovich (Russia) Picard: "Crater, after coming out of shadow after ech. was unsually hazy. next FM it was back to normal". The cameron 1978 catalog ID= and weight=3. The ALPO/BAA weight=1.

On 1970 Aug 17 at UT 02:40 Pedler (England) noted that the shadow flowed around instead of over Plato. Wondered if shadow matched the gray of the crater. Within minutes the shadow line looked normal again. At 04:41UT Claudio Pamplona (Brazil) saw a pulsation in Plato during a lunar eclipse. He thought that this was due to falling temperatures. The Cameron 1978 catalog ID= 1274 and the weight=0. The ALPO/BAA weight=1.
Eratosthenes 1949 Oct 07 UT 04:14-05:22 W.Haas (USA) and O'Toole (USA) observed some changes in intensity of features inside this crater - after a lunar umbral passage. The effect lessened over time.

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 Aristarchus was an oval shape with no details seen. It had a ray extending from the south west rim (normal). The north rim was slightly blue and the south west rim very very slightly red. At 23:55UT it was clearing and details showed. At 00:02UT it was clear. Sketches were provided. Cameron comments that the colours fit Fitton's predictions on spectral dispersion in our atmosphere from atmospheric inversions. The brightness measued was 10+ and normal should be 9, and the plain is 4.5. The Moon's altitude at the LeCroy site was 45 deg. The Cameron 1978 catalog ID=1418-1420 and weight=5 (1-0 for LeCroy report). The ALPO/BAA weight=3.
On 1989 Aug 17 at UT 01:02-04:20 G. Kolvos (Thesaloniki, Greece, 4"reflector) measured (using photometry) that although there was a gradual fade over the Moon as the eclipse progressed, there was a 2"% rise in brightness of Aristarchus.Graphs were submitted and photos. A.C. Cook supplied CCD images and CCD photometry. A photograph by Conway (Sun Prarie, WI, USA) at the start of the eclipse reveal a bright colourless spot (aparently confirmed). The Cameron 2006 catalog ID=373 and weight=5. The ALPO/BAA weight=2.
Kepler 1967 Oct 19 UTC 05:00 Observed by Classen (Pulnitz Obs. East Germany, 8" reflector) and Corralitos Observatory (Organ Pass, NM, USA, 24" reflector + moonblink) "It was 1 mag brighter than aristarchus when normally Aris. is 0.3mag. brighter than Kep. Corralitos MB did not confirm." NASA catalog weight=4 (good). NASA catalogue ID #1052.
Aristarchus 1966 Oct 30 UTC 01:32-01:48 Observed by Bartlett (Baltimore, MD, USA, 5" reflector x79, x142, x194, S=5, T=3) "S.region of floor granulated & 6 deg bright light brownish tone; rest of crater 8deg bright white". NASA catalog weight=4 (good). NASA catalog ID #992.
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.
On 1988 Apr 03 at UT02:25-02:30 Culver (Harker Heights, X, USA, Meade 2045 reflector, x40, seeing=turbulent) detected flashes coming from just north of the centre of Mare Tranquilitatis. Some of these flashes were of a duration of seconds whilst others were several minutes. Altogether ~20 flashes were seen, and not in the same place. "5 small star-like points could be located - and there were lots of craterlets". The spots were "lined up E-W at N of 10 deg latitude." Colour was not visible on these nor variations. Apparently the observer had seen this type of TLP before but had not reported them. The Cameron 2006 catalog ID=323 and weight=2. the ALPO/BAA weight=2.
On 1970 Aug 12 at UT21:00? an unknown observer commented about Plato: "Light #22, remarkable increase in brightness. #32 subsided & #14 shone out then faded & #16 brightened. (Fort says that till Apr. 1871 selenog recorded 1600 obs. of fluctuations of lights in Plato & had drawn 37 graphs of indiv. lights. These were deposited in the library of the Royal Astronomical Society by Birt)." The Cameron 1978 catalog ID=169 and the weight=3. The ALPO/BAA weight=2.
On 1992 Jan 20/21 at UT 23:49-00:15 M.C. Cook (Frimley, UK, 3" Questar telescope, x130, seeing=III) managed to see the central craterlet in Plato and an unnamed one north west of Mons Pico. Cameron comments - "were this & No. 429 LTP or just good seeing?)." Note it is possible that she mean LTP 439 in which case it would refer to the previous nights TLP. The Cameron 2006 catalog ID=439 and the weight=2. The ALPO/BAA weight=1.
In 1942 Feb 02 at UT 18:20-19:15 Y.W.I. Fisher (Brussels, Belgium) a whitish glow near the Earthlit limb, near to Kepler (37W, 7N). The duration of the event was 55 min. The Cameron 1978 catalog ID=488 and weight=2. The ALPO/BAA weight=1. Ref. p220-221 IAU Symposium No. 14 - The Moon.

On 1992 May 19 at UT 01:00-02:05 P. Moore (Selsey, UK, 15" reflector, x260) saw at 01:25UT an unmistakable red-orange glow on the south and south-east rim with the "Spur". 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. The Cameron 2006 catalog ID=446 and the weight=0. The ALPO/BAA weight=1.
On 1992 May 19 at UT 01:00-02:05 P. Moore (Selsey, UK, 15" reflector, x260) noted that the southern slope of Mons Pico had a tint of colour. No other features revealed colour apart from Aristarcus, where a TLP was going on. The Cameron 2006 catalog ID=446 and the weight=0. The ALPO/BAA weight=1.
