This photographic sequence shows a gradual widening towards Cassini and by the 3rd exposure the band is touching (and then obscuring) Cassini. A "fan" was visible in the north east and WSW directions, later this was seen as rays and this was even seen in the view finder of the camera. Cameron comments that this might be lens flare but suspects that it would not have been seen in the view finder. The Cameron 2006 catalog ID=427 and the weight=5. The ALPO/BAA weight=2.

Cameon comments that the albedo must have been at 5, where normally it is 4.5 and the nearby plain is 5). Cameron 1978 catalog ID=1322 and weight=2. ALPO/BAA weight=2.
Theophilus 1978 Nov 08 UT 20:49-22:00 Observed by J.D. Cook (Frimley, 12" reflector, 6mm Ortho eyepiece, seeing III-IV) Orange discolouration seen on ESE crater floor. Moon blink tried, but no blink detected. By 21:10 the effect had lessened, but was still orange. By 21:50-21:58 the effect was smaller and perhaps more on the SE of the floor. Colour confirmed by Foley. Fitton may also have been observing. At 22:00 A.C. Cook observed and commented that a darkish, perhaps brown-orange colour seen - but suspected it was probably spurious colour - but by now the seeing was V. J.H. Robinson, whilst doing a Moon Blink sweep of several features, including Theophilus, had not noticed anything unusual 18:50-19:10. By 22:30-22:35UT, he still could not detect a blink, but noticed intermittent darkining on the shaded area on the E. floor, but seeing was now IV. The darkening was more noticeable in blue than red light. BAA Lunar Section observation. 2006 Cameron catalog ID #40 weight=3. ALPO/BAA weight=1.
Fracastorius 1975 Apr 19 UT 19:47, 20:40, 20:45 Observed by Robinson (Teignmouth, UK, 26cm reflector) "Fracastorius had a blink - it was bright in red and darker in blue at these three times, and probably in between. This was possibly natural surface colour being detected?". ALPO/BAA weight=1.

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.
Alpetragius 1958 Nov 19 UT 22:00-22:05 Observed by Stein (Newark, New Jersey, USA, 4" refractor) "Shadow anomaly. Portion of shadow vanished, replaced by lighter shade. At 22:05 gradually darkened & was normal in 20 sec." NASA catalog weight=3. NASA catalog ID #704. ALPO/BAA weight=2.
On 1980 Jan 26 at UT21:35-22:25 Blair (Refrewshire, Scotland, 10" reflector, 83-276x, seeing=III-IV and transparency poor) discovered a bright spot on the north rim and through filters it "flashed" green, red and blue.

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.

In early sunrise conditions, W. wall was less brilliant than usual -- matched only by Sharp, Bianchini, & Marian. Extraordinary detail could be seen on this wall. Also noted intense & distinctly blue color entire length of W. wall. 3 others corroborated detail, but not color. Moore found things normal & saw Aris. brightest at 2030-2125h tho Argent & Brumder made it < Proclus" NASA catalog weight=4. NASA catlog ID #1422. ALPO/BAA weight=1.
On 2013 Apr 22 UT 01:39-02:37 P. Zeller (Indianapollis, USA, 10" f/4 reflector, x200, seeing 6, Transparency 3 - scattered cirrus) observed visually (depicted in sketch) the two closely spaced NW wall dark bands) to have a rusty-red hue. The colour of these bands did not change over the period of the observing session. Images were taken, but resolution and image S/N is not sufficient to resolve separate bands here, or to detect colour. The ALPO/BAA weight=2.
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
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 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.
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.
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 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.

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.
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.

Proclus 1950 Jul 27 UT 02:56 Observed by Bartlett (Baltimore, MD, USA) described in the NASA catalog as: "C.p. of Proc. disappeared)" 5" reflector used at x100, NASA catalog weight=4. ALPO/BAA weight=2.
In 1962 Dec 09 at UT 07:42 Wildey and Pohn (Mt Wilson, CA, USA, 60" reflector) observed that Aristarchus was 0.80 magnitudes (x2) fainter than average for this age (photometric measurement) Vmag=3.80, average= 3.0. The Cameron 1978 catalog weight=5. The ALPO/BAA weight=2.
In 1962 Dec 09 at UT 07:36 Wildey and Pohn (Mt Wilson, CA, USA, 60" reflector) observed that Oceanus Procellarum was 1.13 magnitudes brighter than normal. Observation at sunrise and is abnormal if area measured was mare. If it were an east facing wall it would be normal. The Cameron 1978 catalog weight=5. The ALPO/BAA weight=2.
On 1992 Feb 16 at UT 01:05-01:35 P. Moore (Selsey, UK, 12.5" reflector, seeing=III) found the north rim area to be both very bright and misty - though he did not think it to be a TLP but wanted it to be recorded, just in case. The Cameron 2006 catalog ID=440 and the weight=1. The ALPO/BAA weight=1.
Aristarchus-Herodotus 1970 Apr 18 UT 20:14 Observed by MacKenzie (UK,2.5" refractor x45, seeing Antoniadi I) "Fairly strong blink in a spot 1/2 way between the 2 craters. Drawing (Apollo 13 watch). NASA catalog weight=2. NASA catalog ID #1257. ALPO/BAA weight=2.
Herodotus 1950 Jul 27 UT 03:56 Observed by Bartlett (Baltimore, MD, USA) described in the NASA catalog as: "Pseudo c.p. in Herod. Drawings. (Similar to NASA catalog event #523)" 5" reflector used at x100, NASA catalog weight=4. ALPO/BAA weight=3.
Torricelli B 2002 Oct 18 UTC 20:56-21:59 Observer: G.North (UK, 8" reflector, x134, Seeing Antoniadi IV, Transparency good) - thought that Torricelli B was perhaps a little brighter than expected, especially when compared to Moltke and Censorinus based upon past recollection of relative brightnesses at this colongitude). Slight bluish tint seen as well. The ALPO/BAA weight=1.
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.
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.
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.
Aristarchus 1972 May 25 UT 19:32-19:38 Observed by Leitzinger (8.75E, 48.75N, Germany, 60mm f/15 telescope T=2, S=2) "Bright point at SE wall well visible, colour changed to orange shortly before it disappeared" published in Hilbrecht & Kuveler (1984) Moon and Planets, Vol 30, p53-61.
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 1963 Nov 28 at UT 22:30-00:00 Fisher (Colefax, CA, USA, 8" Newtonian reflector)observed a yellow on crater rims adjacent to Anaximander. Yellow colour also seen on Aristarchus that night. The ALPO/BAA weight=1.
Eratosthenes 1936 May 04 UT 05:40 Observed by E.P.Martz (Mandeville, Jamaica) "Detected bright spots on floor" NASA catalog weight=3 (average). NASA catalog ID #414. Ref. Haas, W. 1942, J.Royal.Ast. Soc. Canada, 36, 398. ALPO/BAA weight=1.

Interior bands were faint at 22:40 but sharper at 23:20. Observer noted some blue spurious colour to the north of Aristarchus but this had gone by 23:50.
Observer noted some variability in the brightness of Moltke and Torricelli B. This observation has an ALPO/BAA weight of 3.
Observer noted some variability in the brightness of Torricelli B and Moltke. This observation has an ALPO/BAA TLP weight of 3.
Aristarchus 1996 Oct 25 UTC 19:05-19:55 Observed by Livesey (Scotland, 65mm reflector x88) "red colour seen along E/SE rim and along S.edge of SW ray - colouration not visible on other craters. 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.
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.
1964 Jul 23 UTC 04:45-06:07 Observed by Bartlett (Baltimore, MD, USA, 5" reflector, x180, S=1-4, T=3) "S.region of floor was granulated & rated 6deg bright, rest of crater 8deg. 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.
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.
Near Aristarchus 1788 Apr 19 UT 20:00? Observed by Schroter (Lilienthal, Germany) Event described as: "Small area very brilliant & other bright spots". No additional references given. NASA Catalog Event #44, NASA Weight=4. ALPO/BAA weight=1.
On 1985 Sep 28 UTC 20:54-23:52 P.W. Foley (Suffolk, UK) found (actually before 20:54 UT) brightness variance in Torricelli B. J.D. Cook (Frimley, UK) observed a brief blue coloured patch somewhere in the Torricelli B region, but could not pin it down precisely. At 22:50UT M.C. Cook (Frimley, UK, 30cm reflector, seeing III - occasionally V, transparency moderate to good) Found the crater to have an elongated appearance (in SSW-NNE direction) in white light, similar to the previous night. A bright elongated spot was seen on the NNE floor, close to where the wall should be. Not able to define the rim. There was a very dark surrounding area to the crater, similar to what it was on the previous night (roughly 1/4 brightness of Censorinus). 23:04UT brighter in yellow, then red, then blue. At 23:10 it was seen that blue filter dulled the crater - this was odd because both Censorinus and Proclus were brighter in blue, which is what he would normally expect. At23:15 UT Censorinus was brighter in blue, then yellow then red filters and some orange spurious colour seen to the south of Censorinus. At 23:23UT no spurious colour seen on Proclus or Censorinus. 23:46UT Torricelli B elongated as before, but a very faint ray might have been seen to the south west of the rim. This report is not in the 2006 Cameron catalog. The ALPO/BAA weight=3.

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 1995 Apr 03 at UT 03:30 Unknown Observer (Transparency good) saw a darkening in the Cobra Head, Schroter's valley area of Aristarchus - the best example that he had ever seen. The Cameron 2006 catalog ID=474 and the weight=3. The ALPO/BAA weight=. Reference - BAA Lunar Section circular 1995 Oct, p125 and personal communication from David Darling to the BAA on 6/6/1995. Note it is uncertain whether this refers to the Clementine mission or to somebody who observed during the Clementine mission, or somebody with that surname. Anyway if it is the Clementine mission then the date is wrong - possibly the year should have been 1994? The Cameron catalogue does actually mention a TIFF on Clementine mission? The Cameron 2006 catalog ID=474 and the weight=3. I am assuming that the year should be 1994 and not 1995? The ALPO/BAA catalog weight=1 until we can find out what the correct date is?

On 1996 Feb 12 at UT 07:30-08:27 J.Sandel (Caycee, SC, USA) noted a contrast effect inside Tycho at sunset. At 07:30UT there was a slight, but definite illumination of small areas of the crater floor west of the central; peak. Also seen by T. Ferrel (Lawrenceville, GA, USA, SCT C8). This was oval in shape and gray in colour - Ferrel noted some diffuseness. It brightened over 30 minutes. At 08:11UT a definite brightness fade noted in Tycho's central peak.

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.
Aristarchus 1970 Jul 26 UT 15:00? Observed by Sekiyuchi (Tokyo, Japan, 36" reflector) "Polarimetric and photoeletric anomalies on Moon" NASA catalog weight=5. NASA catalog ID #1268. ALPO/BAA weight=5.
Aristarchus 1983 Aug 03 UT 0305-0400 Observed by R,Moseley (Coventry, UK, 6" reflector, seeing II, Transparency very good). At the start of the observation, the NE wall and immediate exterior was the brightest area visible (this is normal) and seemed tinged with a faint blue/violet. At 03:45 the impression of colour was fading in the brightening sky, but by 03:55 the colour was back again with a faint violet/purple surrounding the whole formation from E clockwise to N. The observer found it difficult to decide whether it was really a colour on the Moon, or an optical illusion. ALPO/BAA weight=1.
On 1940 Dec 25 at UT 10:00? Haas (New Mexico, USA, 12" reflector?) observed the northern horn to be elongated by about 10'. The Cameron 1978 catalog ID=482 and weight=3. The ALPO/BAA weight=2.
