Spain (Fairfield, KY, USA, 8" reflector, S=VG) detected a streak and flashes but reports that the crater was not "glowing", though it was the brightest feature in the Earthshine, but Kepler and Copernicus were bright too. Aristarchus was brighter in shorter exposures than in longer exposures. The Cameron 2006 catalog ID=326 and weight="confirmed". The ALPO/BAA weight=2.

On 1981 Oct 02 P. Madej (Huddersfield, UK, 77mm refractor, seeing I to II) noticed that at 20:48 UT Aristarchus had a 2nd magnitude star-like point on the NE rim (x38). At x83 he could see a small disc of around 3-6 arc sec in diameter, and at x111 it looked the ame but bluish-white in colour. He was able to see Aristarchus, Herodotus, and Vallis Schroteri. Observations ceased at 21:27 UT due to trees blocking the view. The ALPO/BAA weight=1.
On 2002 Aug 12 at UT 19:27 James Cook (Chelmsford, UK) detected a flash on the Moon. The ALPO/BAA weight=1.
On 2011 Apr 07 UT 19:45-20:10 Aristarchus was seen to be “very bright” in Earthshine. Giorgio Sancristoforo (Milan, Italy, 203mm SCT, atmospheric seeing good) noticed Aristarchus to be exceptionally bright (Sketch supplied) at around 20:00 and was the first to report this. Although he did not record the start and end times, he commented that the effect lasted 20-30 minutes and then was significantly reduced in brightness. Although direct comparison in terms of brightnes could not be made with a star, he thought Aristarchus to be brighter than +0.7 in magnitude (Saturn). Furthermore Aristarchus was visible when daylight was still present, when looking through the telescope, although it could not be seen with the naked eye due to too much extraneous light. Aristarchus was probably white in colour, but the observer was partly colour blind and so was uncertain. Not much detail was seen elsewhere in Earthshine, even when the sky darkened, and he was not able to see Kepler or Copernicus, just the limb. No details were seen in Aristarchus itself, for example no ray to the SW was visible. It later transpired that Lajos Bartha (Budapest, Hungary, 70mm refractor, x83, seeing conditions good) had observed Earthshine even earlier from UT19:45-20:10 and noticed a bright area close to the edge of the Moon that he later confirmed was Aristarchus. When he started observing the sky twilight was still a deep blue, but the dark side of the Moon was seen both with the naked eye and through the telescope. Earthshine was medium in brightness and grey in colour. Copernicus and Kepler were weak in brightness but certainly visible. There was some scattered light from the sunlit side of the Moon noticed, but not enough to obscure Copernicus and Kepler from visibility. As a test he moved the telescope around and the bright spot moved with the Moon and so was not a glare problem. The following day he checked Earthshine again but found that the bright spot was not so conspicuous. As a footnote, Tim Haynes (UK) had been observing an occultation of 37 Tauri, much earlier at 19:14UT, through 10x50 binoculars. He commented that Earthshine was visible, but that he hadn't noticed Aristarchus - though he was not looking at the Moon specifically to see this crater. ALPO/BAA weight=3.

Wisniewski (Chicago, IL, USA, 8" & 6" reflector, x123) found Aristachus to be unusually bright and "glowing" as a blue-white magnitude 8 disk, though it faded close to the end of his observing period (02:30-02:50). A ray from Tycho could be seen in the direction toards Aristarchus crater. Darling (Sun Praire, WI, USA, 12.5" reflector, x50) found Aristarchus Z to be both bright and diffuse. The Cameron 2006 catalog ID=363 and the weight=2. The ALPO/BAA weight=1.

On 1994 Jan 16 at UT19:30-21:10 D. Strachen (England, UK, 4" refractor, x21 and x143) whist looking at an occultation of ZC3453, saw a bright spot in Earthsine, just north of Aristarchus (47W, 25N) at position angle 30deg-40deg, only a little way in from the limb. It appeared like a star through haze and a few seconds of arc in diameter. It was Visible for more than 1 hour until 20:50UT although had faded somewhat by that time. However J. & M. Cook (Frimley, UK, 12" reflector, x143 and x244) saw nothing in Earthshine from UT 20:02-21:10. The Cameron 2006 catalog ID=472 and weight=1. The ALPO/BAA weight=1.

On 1991 Jun 16/17 at UT 20:30-00:30 T. Castro (Sao Paulo, Brazil, 24" reflector, x500) observed "Large white spot with a comet-like tail extending eastwards (celestial) on of the shore of Mare Crisium at 52.5E, 21.5N." This was confirmed by several other observers and apparently video recorded. The effect was seen on several nights but had faded completely by 20th June. J. Westfall (San Francisco, CA, USA) also videod the spot but on Jun 21. The Cameron 2006 catalog ID=429 and the weight=5. The ALPO/BAA weight=1.
On 1881 May 04 UT 20:00 "Gamma" a psuedonym for an astronomer (Germany?) observed Aristarchus to be be a very bright 8th magnitude star with pulsations. The Cameron 1978 catalog ID=221 and the weight=3. The ALPO/BAA weight=2.

On 1966 Sep 20 at UT 03:22 Three Astronet observers (Phoenix, AZ, and Los Angeles, CA, USA) (independently?) reported flashes in Grimaldi crater. One observer was in Phoenix AZ, and another in Losa Angeles, CA, so probably not due to the atmosphere. Cameron comments that the astronaut Schmidt on Apollo 17 saw a flash in it while orbiting the Moon. the Cameron 1978 catalog ID=977 and the weight=5. The ALPO/BAA weight=4.
Grimaldi 1969 Jul 19 UT 20:39-20:45 Delaye (France, 25cm refractor) saw a bright bluish spot near Grimaldi. 20:43 a flash was seen by Thinon. Delaye saw flashes at 20:44 and 20:45. Between 21:00 and 23:00 (J. M. L.) da Silva (Rio de Janeiro, Brazil, 19.5" refractor) saw a bright spot on the W (IAU??) of Grimaldi. However there is a bright spot near Grimaldi, so this maybe normal. NASA ID = 1167. The ALPO/BAA weight=2.
On 1975 Dec 08 at UT18:00-20:40 P.W. Foley (Wilmington, Kent, UK, 12" reflector, x60-x624, seeing II, slight mist) found Aristarchus to be less well visible than features such as: Grimaldi, Reiner, Darwin/Byrgius, Kepler, Plato and Sinus Iridum. Earthshine was exceptionally good tonight and was orange/red in colour. Photographs were taken and these confirmed the apparent dullness of Aristarchus. ALPO/BAA weight=2.
On 1990 Mar 31 at UT 21:30 L. Jackson (England, UK?) observed a red glow in Earthshine in Gassendi as shown in a sketch. Apparently Gassendi can often show up red colours (according to Cameron) but rarely is this seen in Earthshine. Foley saw the sketch and suspects that the location was Gassendi. The Cameron 1978 catalog ID=397 and weight=2. The ALPO/BAA weight=3.
South Pole 2011 Apr 08 UT 19:30-20:00 A.Kemp (Mold, Flintshire, UK) observed that the Leibnitz peaks at the southern pole stood out sharply. However one of the peaks was “shining like a spot light. So bright that I couldn’t make out its shape”. – image clear and steady with excellent transparency and seeing in the 70mm f/13 refractor (25mm and 10mm eyepieces). Inspections during the above time period revealed no changes in brightness. Previous observations of this area had never shown such an unusual brightness, and Arthur likened the brightness to “a maximum brightness of Venus shining amongst 2nd magnitude stars”. The observer was an experienced observer. ALPO/BAA weight=2.

An English Moon Blink device showed it dark in blue and opaque in red. Reddening remained unchanged while comparing it to adjacent region and Aristotles. Colour index was toward dirty orange. Colour most apparent in the good moments of seeing and disappeared in the poorer moments of seeing, Cameron says that this is opposite to what was expected if the effect was atmospheric in origin and no colour was seen in Aristotles.

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.

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 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.
Campanus 2014 Jan 11 UT 22:00-22:30 S.Bush (UK, 6" SCT, x180, seeing average) made a sketch of the Campanus and Mercator craters. He found that the central peak of Campanus difficult to resolve and the floors of both craters were devoid of detail. Mercator was the lighter shade of the two floors. Earlier at 19:47 UT M.Brown (Huntingdon, UK) imaged this region and using Registax resolved details on the floors of both craters, though Mercator clearly was slightly lighter in floor shade and had less detail on its floor than Campanus. The most likely explanation was that it was just seeing effects blocking the visibility of detail - this of course is less of a problem for a Registax usid on the CCD image. However just to be sure this observation is being given an ALPO/BAA TLP weight of 1, to encourage visual observers to attempt this observation under similar illumination and seeing.
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 1938 Mar 13 at UT 04:00-06:00 Barker (Chestnut, England, UK) noted a slight reddish colour in Plato. However Fox (Newark, UK, 6.5" reflector, x240) saw none on the south east wall, but instead saw a yellowish glow on the southern floor at the same time (confirmation?). Appearently Fox saw the same effect on Apr 10, 11, and May 8-11, then on June 8-10. The Cameron 2006 catalog ID=432 and the weight=5. The ALPO/BAA weight=3.
On 1989 May 17 at UT Fabian (Chicago, IL, USA, 4" reflector, x35-x50 and 8" reflector) noted a pale blue colouration in the ridges situated west of Aristarchus and north of Herodotus craters, in the vicinity of the terminator (and on the night side). Aristarchus itself did not have any colour. Ďt was only area with such color though there were numerous others of similar elevation and relation to term. The colour was seen in a 4" Cassegrain telescope, but when an 8" reflector was used at 02:30UT, even with the same eyepieces. Cameron comments that maybe the larger telescope spread the colour out? The sketch that Fabian suplied, suggested to Cameron that the TLP was located at Herodotus, and the ridge was part of Schroter's valley - Cobra Head. The Cameron 2006 catalog ID=364 and the weight=2. The ALPO/BAA weight=2.
On 1978 Jan 20 at UT19:10 P.W. Foley (Kent, UK, 12" reflector) observed a red spot at the southern edge of Gassendi C. P. Moore (Slesey, UK, 15" reflector, S=II-III) reported nothing unusual 17:00-17:50. Turner and others reported negative at 22:01.

On 1975 Feb 22 at 19:00-22:50 Fitton (Lancashire, UK, 8" reflector, seeing=II-III-I) saw Aristarchus (at 19:00UT) blue, with no obscuration visible in white, red or blue filters. This was not a telescopic effect. "Obs. 4.5h. Says it & next 5 nites obs. were due to high pressure system W. of obs.". Foley found nothing unsual in Aristarchus in his observing session, which overlapped Fittons. The 1978 catalog ID=1396 and weight=3. The ALPO/BAA weight=1.
On 1975 Feb 22 at 20:04-22:50 P.W. Foley (Kent, UK, 12" reflector, seeing=good) observed Prinz to have a diffuse white obsecuration. There were pulsations of 30-50sec intervals. Effect ceased at 22:50UT and indeed was fading earlier from 22:35UT. Photgraphs were taken but showed nothing unusual and no colour. Aristarchus was also negative. The Cameron 1978 catalog ID=1396 and weight=3. The ALPO/BAA weight=2.
On 1969 May 28 at UT 02:18 Delano (Taunton? MA, USA, 12.5" reflector, x300) suspected a short duration flare up on the W wall of Aristarchus at 0.682 and 0.397, but it may have been due to poor seeing. No events seen at Kepler (Apollo 10 watch). The Cameron 1978 catalog ID=1149 and weight=4. 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.
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.
40-54W, 54N-60N i.e. nr. South? or J.Herschel 1913 Jun 15 UT 22:00? Observer: Maw (Surrey, UK, 6" & 8" refractors) "Small distinct redish spot which became diffused into a patch as term. advanced on the plateau NE of the crater South. When the plateau was on the term. (Goodacre says the crater was J.Herschel for same date -- 2 different spots or misident. for one?" NASA catalog weight=3. NASA catalog ID #345. 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 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.
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.
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.

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.
Aristarchus 1963 Oct 30 UT 01:50-02:15 Observed by Greenacre and Barr (Flagstaff, AZ, USA, 24" Clark Refractor) observed 2 ruby red spots - one just to the SW of the cobra's Head and the other on a highland area east of Vallis Schroteri. A pink colour formed coverting the SW rim of Aristarchus. Effects present with or without Yellow Wratten 15 filer. Similar effects checked for elsewhere on other craters but not seen. So presumed not to have been due to chromatic aberation or astmospheric dispersion. Effecta not seen in 12" refractor, but this may have been a resolution issue. The NASA catalog ID No. is #778. The NASA catalog weight is 5 (highly reliable). ALPO/BAA weight=4.
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.
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=2.
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.
Aristarchus and Cobra Head 1966 Jul 30 UT 06:35-07:29 Observers Ariola and Cross (Whittier, CA, USA). NASA catalog states: "S. part of Cobra Head nr. Herodotus was a red spot; also nr. Aris. & the fork of Schroter's Valley. Variations in phenom. color, 1st on S. rim of Aris., later on N. rim. Drawings". 19" x390 reflector used. NASA catalog weight=5. NASA catalog TLP ID No. #959. ALPO/BAA weight=4.
On 1975 Feb 23 at UT 18:00-00:24 P.W. Foley (Kent, UK, 12 inch reflector, seeing Good), noticed that Aristarchus was a slate-grey tinged with blue, and abnormally bright, fading at UT 18:47, and decreased activity at UT20:45 after a cloudy period. Blue was seen on the northern wall at UT19:00, but at 19:10 no colour, but instead an obscuration. All normal from UT 21:04-21:46 according to Foley. At UT19:00 G. Amery (Reading, UK, 10 inch reflector) noted shadowy grey near the shadow under the south wall, indistinct small area, no colour. At UT 20:00 activity increased. Colour negative fr. 150-300x till 21:10 (Hunt, Cambridge, UK, 2.5" refractor, seeing Poor-Very good). Negative fr. 20:20-21:00 in bad seeing, and very good seeing at 200x all negative (colour blink filters). From 23:45-00:20UT (Fitton, Lancashire, UK, 8" reflector). Turner of Sussex, UK with an 8" reflector, observed as well. (confirm. of activity earlier & neg. later). Cameron 1978 catalog ID=1397 and weight=5. ALPO/BAA weight=3.
Aristarchus 1963 Oct 30 UT 05:00-08:00 Observed by Greenacre and Barr (Flagstaff, AZ, USA, 24" Clark Refractor) a violet or purple-blue colour formed beyond the NW of Aristarchus. ALPO/BAA weight=2. This followed an earlier observation that night of two red spots and a pink glow.
On 1981 Oct 11 at UT 00:05-02:00 B.Hobdell (St Petersberg, FL, USA, 4" refractor, S=3 and T=5) observed a brightening on the floor of Plato. 4 bright spots appeared and vanished and there was a fith one in the centre that was very bright at times. At UT 00:14 the central spot became bright then was "followed by a haze permeating entire floor, heaviest in the northern quadrant. Came from 2 S peaks or white spots, shaped like a boomerang extending to presumed c.p. (c.c ?). White flashed at 0052 from it cloud changed shape - spread N. At 0136 brightening from c.c. area 0419 dissipated. All white spots seen at 0200. Its outer flanks seen clearly the whole time". The above is quoted from the Cameron 2006 catalog ID=155 and weight=3. The ALPO/BAA weight=3.

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.

Aristarchus 1975 Feb 24 UTC 18:00-23:30 Observers (all in UK): Foley (Kent, 12" reflector), Gannon (Middlesex, 6" reflector), Peters (Kent, 8" reflector), Farrant (Cambridge, 8" reflector), Turner (Sussex, 8" reflector), Fitton (Lancashire, 8" reflector) - "(Foley) 1800h -- slate gray bluish on all of crater; blue at 1816h, fading at 1835h, no color on floor. At 1949h brillinance reduced, eyepiece tested at 1959h with result of elong. gray blur & afterward activity at reduced light level. Blue again at 2013h. (Gannon) at 1851h saw red tint on S.rim (instru.), neg. in white & filter lite till 2000h, (Peters) at S=P had impression of large faint blink on S.side, diffuse till 2000h, then seeing improved & saw darkish patch on S.wall -- darker in blue than red. Craters on limb were normal to 2017h, neg. at 2058h & 2130h, (Farrant) at 2000h, normal. At 2053h color in small area to W. of W. wall. (Turner) at 2230h-2300h got neg. (Fitton) at 2330h got neg. in white, seeing too poor for filters. Fitton & Farrant think obs. due to atm. effects. (activity earlier & none later confirmed)." NASA catalog weight= 5 (very good). NASA catalog ID #1398.
On 1983 Aug 22 at UT 05:44-06:33 D. Louderback (South Bend, WA, USA, 3"refractor, x150) found the brightness of Aristarchus (diffuse white patch) to be 7 to 7.5 but apparently it is normally 8-8.5, so fainter than normal. Another brightness reading found "brightening then nearly extinction at S. wall similar to changes seen on Eimmart before. Watched fluctuation compared to Cobra Head, they were similar but more pronounced at Aristarchus" especially in blue light compared to red (although there was a little brightness in red). Timings of these fluctuations were 7sec, 7sec, 9-10sec and 9-10sec. The latter two might have been seeing related as the crater enlarged up at these times. The observer felt that the Cobra Head appeared fainter than the previous year and had faded during the second set of brightness measurements. Cameron 2006 catalog ID=227 and weight=3. ALPO/BAA weight=2.
On 1983 Aug 22 at UT05:44-06:33 D. Louderback (South Bend, WA, USA, 3" refractor, x150) found that Mons Piton was still brighter in red light than in blue - the opposite was found in his July observations. The Cameron 2006 catalog ID=227 and the weight=3. The ALPO/BAA weight=2.
On 1981 Oct 12 at UT 00:00?(?) B.W. Chapman (12cm refractor, Seeing II, transparency poor, Kingston-Upon-Thames, UK) found that Mons Pico was brighter in red light than in blue. Aristarchus for comparison was the same brightness in both filters. ALPO/BAA weight=1.

Plato 1945 Oct 19 UT 23:24:30 Observed by Thornton (Northwich, England) described in the NASA catalog as: "Bright flashes on the floor near E.wall (meteor?) but others have seen flashes there too. time given is 1123, must be P.M., local time. MBMW gives date as Oct 19, which is wrong" Haas (more reliable account) in his 2003 article in Strolling Astronomer Vol 45, p28 states" 23cm x220 reflector used - "minute but brilliant flash of light seen just inside eastern border of walled plain Plato. Colour was said to be orange side of yellow. NASA catalog weight=4 & NASA catalog TLP ID No. #494. ALPO/BAA weight=3.
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.

Galvani B: On 2019 Sep 13 UT 23:26 K. Kilburn (Manchester, UK, BAA - ED80 refractor, x2 Barlow, Canon 550 DSLR) took a sequence of images from 23:25-23:27 UT. On one of the images, taken at 23:26UT there is a blue/green spot on Galvani B. There is a hint of a possible fade of the spot in the other images but this is not conclussive. Te spot might just be a cosmic ray event or a bright part of the crater rim coming into view under brief exceptional seeing for one frame only. We need simlar illumination, and if possible topocentric libtation images, under different atmospheric conditions to confirm this. It would be great if the images were in colour too. The ALPO/BAA weight=1.

On 1989 Apr 09 at 02:13 was seen to be not very bright in binoculars, despite visibility of Earthshine in general as being exceptional. Darling confirmed this at 02:31UT, though it was quite bright in a 17" reflector,but Herodotus could barely be seen. Weier claimed to be able to see Aristarchus with the naked eye. At 02:08 the brightness was found to be 5.0 for several measurments. The observing team ware from the Maddison Asgtronomical Society, WI, USA. The Cameron 2006 catalog ID=359b and he weight=3.

On 1990 Apr 28 at UT 00:00-00:30 F. Graham (Marshall TWP, OH, USA, 6" reflector) during a failed attempt to observe the occultation of X6493 that was thwarted by clouds, noticed that Gassendi was "Gass,>>,>Aris or anything else". The crater had a "milky lustre". It is possible that another occultation observing group may have a video of the Earthshine at this time. Darling (Sun prairem WI, USA, 20x50 binoculars) could not see Earthsine, though the sky was bright at the time. The Cameron 2006 catalog ID=402 and the weight=0. The ALPO/BAA weight=1.
