Boroughbridge, England. The 2006 Extension catalog by Cameron assigns an ID No. of 4 and a weight of 1. The ALPO/BAA weight=1.
A.S.Williams of West Brighton, UK, using a 5.25" Calver, x150 and definition fairly good. Observer noticed that the Mare seemed covered with a close network of innumerable streaks, and spotted with countless numbers of light specks, so that it would hardly be possible to delineate them all in one night. The spots and streaks together must have numbered ~1000. The observer had never seen anything like the number of spots and streaks. Peirce A, was not at all easy to se and neighboring spots almost as bright made it difficult to distinguish which one was Peirce A. ALPO/BAA weight=3.
On 1976 Apr 10 at 21:15-21:49UT S.Spencer (60mm refractor x60, seeing quite good) noticed a faint red glow at the south west wall of Gassendi covering a span of about 35 deg arc. The observer had some doubts about this because they were using a small telescope, but thought that they ought to report it, just in case. A BAA Lunar Section report. ALPO/BAA weight=1.

Gassendi 1967 Jun 18 UT 22:50-23:59 Observed by Whippey (Northalt, England, 6" reflector?) "Faint redness outside NE & SE wall of crater." Moore (10" Armagh refractor, x360) was observing earlier 22:10-22:40, with and without a Moon Blink but detected no redness, however his observing conditions were not very good at the time. NASA catalog ID #1039. NASA catalog weight=3. ALPO.BAA weight=2.
On 1985 May 30 at UT 20:10-23:54 P.Moore (Selsey, UK, 15" reflector) and at the same time Doherty (Sussex, UK, 15" reflector) observed a strangely bright and pink/red north rim of Aristarchus crater during UT20:20 and 20:36UT. The effect reduced between ~20:39 and 20:44UT. M.C. Cook (Frimley, UK) found the northern wall to have a red/purple colour but the effect vanished after 50 minutes. Cook also saw a "V"- like notch in the NW crater shadow and this appeared to be bigger than normal. G. North (Sussex, UK) saw a tinge of pink colour on the northern rim and a bit later a "ruby red" colour on the north-west wall - again this effect lasted 50 minutes. Moseley verified the colour. Finally M. Hather (Yorkshire, UK) suspected the north wall of Aristarchus to be blue in colour. Cameron suspects that this TLP is not spurious colour because it is in the wrong place. The Cameron 2006 catalog ID=276 and the weight=5. The ALPO/BAA weight=4.
On 1985 May 30 P.Madej (Huddersfield, UK, 77mm refractor, x111 and x250, seeing II-III, transparency good) whole spectrum of colours seen on the central peak area, visible in both eyepieces, and was more prominent at the higher magnification.

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.

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

On 1985 May 31 at UT 20:23-22:00 G. North (Sussex, UK, turbulent seeing) found Torricelli B at 20:23 to be mauve in colour and to be very bright. However the colul had gone by 20:29UT. "Varied in albedo 2s then image blurred at 5-10s (atm) at 2034 became pink). At 21:35UT M. Mobberley (Suffolk, UK) found a white patch in the crater centre and a mag 8 flash was seen (confirmed independently by a 2nd observer ~ 113km away)- there was no shadow. At UT 20:30 P.W. Foley (Kent, UK, 12"reflector, seeing excellent) found no colour, but the brightness was changiong and he confirmed the bright patch on the crater's floor, variable 22:15-22:25UT, "then expanded over rim". The Cameron 2006 catalog ID=277 and weight=5. the ALPO/BAA weight=4.
On 1788 May 17 at UT 21:00 Schroter (Lilleanthal, Germany, 210x reflector) observed small depression, 1, near Aristarchus to be a bright spot, similar to Cameron 1978 catalog ID report #45. The Cameron catalog ID=48 and the weight=4. 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.
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 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.

By 22:48 there was activity on the crater floor i.e. the four bright spots were visible in white light but not in red. In blue the central spot was seen and there were dark radial streaks to the south wall and south east. At 22:50 there was a loss of detail. Other craters were normal. At 23:08 the floor was dark in red, but some details were visible in blue. the effect had finished by 23:35. At21:34 J-H Robinson found Plato to be normal and no blinks, though floor clearer in red than in blue, however the floor detail had gone by 21:57. Blair suspected a dusty patch in north of Plato, especially in red light. at 21:57 and it started spreading at 21:13, then east at 21:15 and then north. Though it faded at 21:25 but was back again at 21:35, and Moon blink colour filters still gave a reaction at 21:50 - the TLP remained strong until 23:50UT.

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.

Observations ceased due to the Moon setting behind a tree. W.Haas thinks that this effect is not unusual at similar colongitudes. Moore checked again under similar illumination and still considers the Aug 20 appearance abnormal. NASA weight=4. NASA catalog ID #545. ALPO/BAA weight=2.
On 1993 Dec 31 at UT 05:00-07:40 S. Beaumont (Cambridge, UK, 12" reflector) "saw a patch of hazy light to NW (from c.p. alpha) at 0550 craters B & J shadow of alpha had not reached E wall yet, but at 0536 it did. Alpha > at 0550. Craters B & J to SE had faded, vanished at 0630. Hazy patch remained around peak, alpha low mainly to NE like a comet's tail. Slightly reddish fringe to E wall. (shown in sketch)". The above has been quoted in full from the Cmeron catalog because the catalog desription is slightly ambiguous and any attempted summary might make the description more unreliable. The cameron 2006 catalog ID=470 and the weight=3. The ALPO/BAA weight=2.
Torricelli B 2002 Oct 23/24 UT 23:25-23:52 Observed by Clive Brook (Plymouth, UK, 60 mm OG x120 + prism) "Observed that Torricelli was very diffuse and Tor B showing shadow ? observer considered a shadow perhaps a little surprising this far from the terminator. Nothing unusual seen by M.Cook at 23:52UT or by A Cook at 00:40-00:52 and indeed other craters did appear to have shadows this far from the terminator ? so perhaps only unusual aspect of the original observation that could not be checked due to poor seeing by the latter observer was the fuzziness.
