On 1984 Nov 28 at UT 17:30-18:05 P. Madej (Huddersfield, UK) found that the crater Hubble had a cream white oval patch for short while that was 2x brighter than it's surroundsings. The Cameron 2006 catalog ID=254 and weight=3. The ALPO/BAA weight=2.
On 25 Jun 1993 at UT 23:30-23:52 Carlos Colesanti (Mairinque, Brazil) obtained two CCD images of Julius Caesar crater and noticed a brilliant fuzzy area on the rim of the crater. This appeared in both images and resembled a fuzzy white blob. Note that this is a REA-Brazil observation. ALPO/BAA weight=1. Cameron (2006) ID=463.
On 1981 Feb 10 at UT21:46-21:49 P. Madej (Huddersfield, UK) found a 2nd mag star-like point on the north east wall of Aristarchus crater. M. Price (Camberley, UK) at 21:46 and 21:49.

Beaumont (Windermere, UK, 30cm reflector, Meade 23A and 38A filters, seeing III, transparency fairly good, some haze) observed a whitish misty effect seen bordering the shadows of the SE rim. It appeared intermittently and was not seen in the violet or red filters. Observers wonders if it could have been an effect associated with the Earth's atmosphere, which was unsteady with some haze. However, other craters appeared normal. The ALPO/BAA weight=1.
Gassendi 1966 Apr 30 UT 21:30-23:28 Observed by Sartory, Ringsdore (England, 8.5" reflector, S=E), Moore, Moseley (Armagh, Northern Ireland, 10" refractor, S=VG), Coralitos Observatory (Organ Pass, NM, USA, 24" reflector, Moon Blink) "English moon blink system detected red spots with vis. confirm. Ringsdore says no color but saw obscuration. (LRL 60-in photos showed nothing unusual by my casual inspection). Indep. confirm. (even E. wall was in dark). Corralitos did not confirm by MB."

Gassendi 1976 Oct 04 UT 20:55-20:58 Observed by Robinson (Devon, England) - observer noted that the east outside wall was bright in red and normal in blue. Note that the Moon was 30 deg above the horizon at the time of the observation. The crater returned to normal at 20:58. Also seen by Moore (Selsey, UK) and Foley (Kent, UK). At 21:25-21:50 D. Sims (Dawlish, UK, 25cm reflector, x300, seeing IV and some cloud at times) noticed a possible obscuration over the southern part of Gassendi. He had been observing earlier at 18:40-19:30 but had not detected a TLP in Gassendi then. 22:11UT Robinson notices that the spot outside the east wall is again bright in red., though by 22:25 it had faded and was gone by 22:28UT. The Cameron 1978 catalog further quotes: "Vivid red spots & general red color seen around rim by 2 obs. At 2209h blood red small area was seen. 1 h later the most westerly (IAU?) of the peaks had become hazy white all other areas were sharp. (Indep. confirm.)." Cameron 1978 catalog weight=5 and catalog ID #1454. The ALPO/BAA weight=3.
On 1977 Apr 29 at UT21:40-23:20 an unknown UK observer reported a TLP in Gassendi crater. The following are reports by observers attempting to confirm activity: J.W. Napper (Didcot, UK, 30cm reflector, x287, Wratten 25 and 44a, conditions clear 5+) received a telephone alert call at 22:00 but the sky was cloudy until 22:30. An initial look revealed nothing unusual, then at 22:54 he observed a colour blink just inside the north wall, appearing bright in red and normal in blue or white light. No loss of detail seen and the effect lasted only 2 minutes. A sketch was made. However the observer stresses that the very bad seeing casts some doubt on this observation. L. Fitton observed using a 8.5" reflector, with Moon blink device at x200, seeing was I- II. All areas negative, including Gassindi from 21:40-21:55 and again 22;00-22:25 and finally 22:50-23:30 negative. Mike Brown (Huntington, York, UK, 30cm reflector, x220 and x350, seeing 3-4/5, and transparency 5/5) - observed from 22:00-23:25UT no colour seen, nor obsecuration, all filters negative, despite seeing a lot of fine setail inside this crater.
On 1987 Oct 04 at UT 02:20 D. Darling (sun Praire, WI, USA, 12.5" reflector, x170, S=8, VG, T=5) obtained the brightest measurement he had ever recorded on the northern rim of Proclus. Brightness 9 and adjacent plain was of brightness 6.5. The Cameron 2006 catalog ID=308 and the weight=3. The ALPO/BAA weight=3.
On 1980 Jul 24 at UT02:00 F. Graham (East Pittsburgh, PA, USA, 6" reflector) took some photos (albeit out of focus) that showed a bright spot on the west rim. Cameron comments that this spot was sharp compared to the rest of the photograph, so was probably a photographic artifact. The effect was not seen in the finder scope. The Cameron 2006 catalog ID=103 and weight=2. The ALPO/BAA weight=1.
Aristarchus 1966 May 01 UT 21:55-22:45 Observed by Paterson, Brown, Sartory, Ringsdore (England, 12" reflector x252 for the former and 8.5"? reflector for the latter) "Eng. moon blink system detected red spots with vis. by all but Ringsdore. Brown saw intense white spot NW of crater wall" NASA catalog weight=5. NASA catalog ID 933. ALPO/BAA weight=4.
On 1989 Sep 12 at UT00:58-02:25 D. Darling (Sun Praire, WI, USA, 12.5" reflector, x159, S=7/10) observed similar light conditions to 1989 Jul 15. At 02:00 he observed pink on the south west wall of Aristarchus crater. At 01:24UT the Aristarchus ray was yellowish, however the entire Moon had a grey-yellow tinge of colour. Chromatic aberation was observed at 01:56UT. By comparison Gassendi was checked and had no colour. At 02:10 the crater wall of Aristarchus was unusual and was quite different in appearance to rims of other craters. The cameron 2006 catalog ID=375 and the weight=1. The ALPO/BAA weight=1.
Aristarchus 1971 Sep 01 UT 20:45-21:05 Observed by Neville, Cunnington (Nottingham, UK, 4" refractor x180, altitude, low) "Saw a bright glow, especially in E. wall (Confirm. but not indep.?)" NASA catalog weight=3. NASA catalog ID #1310. ALPO/BAA weight=1.
On 2004 May 02 at UT03:24 M. and L. van Son (Bremerton, WA, May 1st 7:24PM PST) saw a naked eye flash on the Moon. The observers were glancing up at the Moon in daylight when they saw a bright white flash (observer and his wife together) in the upper/mid Mare Serenitatis region, west of the crater Posidonius. "Larger than how Venus appears". "It was a quick flash like white, intense lightning. I'm not sure how to report degrees of arc but if the face we see is 900, and we start from the east then the flash occurred about 225 arc seconds to the west. This was observed by the naked eye, with clear skies between us and the moon." The observers checked for signs of aircraft vapour trails but could not see any. There is a possibility that it could have been sun glint from an Iridium satellite, but this needs to be checked out and usually these last longer than the observed effect. It would be useful to obtain whole Moon images under the same illunination and libration so that we can judge this observation properly. The ALPO/BAA weight=4.
Herodotus 1965 Jun 11 UTC 21:35-21:40 Observed by Porta, Garau (Mallorca, Baleares, 4" refractor x250) "Red glow in crater at 2140, then clouds stopped obs. After clouds, floor was abnormal rose color" NASA catalog weight=5. NASA catalog ID #879. ALPO/BAA weight=4.

The ALPO/BAA weight=3.
On 1969 Sep 25 at 19:00?UT Azeau (Paris, France, 12" reflector, x100, Seeing = good, altitude=20 deg) observed during an eclipse brilliant points for 30 minutes in Ross. Cameron says that the date given originally (16th Sep) was wrong because the age was 5 days and not full Moon. There was however a peumbral eclipse on Sep 25th at 20:10 (max). The Cameron 1978 catalog ID=1201 and weight=1. The ALPO/BAA weight=1.

"Trident Moon Blink on S. wall creet & c.p. & white spots in crater. No color seen vis. Blink not seen earlier or later. Other craters blinked some but not as strongly. Only Aris. areas blinked when Moon blink was moved around. Observers consider blinks real. Alt. of moon was 50 deg. Drawings. Corralitos say they did not confirm, but they rep't Copernicus, not Aris." NASA catalog weight=5 (very high). NASA catalog ID #1062.
Moving glows seen around the middle of the disk during a lunar eclipse. It is possible that the TLP referred to might have been from the 1783 Mar 18 eclipse instead?
On 1881 Dec 05 at UT 17:09 Johnson observed a dark lunar eclipse. Aristarchus was seen as a white spot in the coppery disk and continued so. Cameron comments that this is the normal apeparance in an eclipse? The Cameron 1978 catalog ID=226 and the weight=0. The ALPO/BAA weight=1.
On 1978 Sep 16 at UT 18:28-18:57 G.Searle (Concord, Sydney, NSW, Australia, 8" reflector, x100, x160, S=III) observed a bright star-like point on the western (IAU) edge of Mare Tranquilitatis (x100) that appeared unlike any other crater and a check of the location revealed no suitably bright crater in that region (from a map?). Changed to a higher power (x160) and it was still there, but not as conspicuous. Observer thinks that this may have been due to the Moon's low altitiude (16 deg) and the seeing. At 18:35 he compared it to the brilliant crater Proclus and found the star-like point to be 75% of the brightness of Proclus. Ken Wallace (Australia) had been taking photos and observed the object at 17:37.5UT. The object gradually faded over the next 15 minutes and by 18:52UT could only be seen in averted vision at x100. By 18:57UT it was gone. The Cameron 2006 catalog ID=38 and weight=5. The ALPO/BAA weight=3.

Other observers noted a thin sliver of white on the edge of the Moon, despite it being in totality. The Cameron 1978 catalog ID=560 and weight=5. The ALPO/BAA weight=5.
On 1978 Sep 16 at UT19:30 R. McKin (Colchester, Essex, UK, 216mm reflector and binoculars) observed that Aristarchus, in the lighter region, during the lunar eclipse, was duller than usual but no less conspicuous than expected. The Cameron 2006 catalog ID=38 and weight=5. The ALPO/BAA weight=1.
On 1964 May 26 UT 04:10-04:35 Bartlett (Baltimore, MD, USA, S=5, T=5). observed that Aristarchus had a strong blue-violet glow on the east wall and EWBS, with a strong violet tinge on the nimbus. Crater was hazy, could not focus it in red, green or blue light. The Cameron 1978 catalog ID= and weight=4. The ALPO/BAA weight=2.
On 1982 Jan 09 at UT18:46-21:42 P. Moore, (Selsey, UK) and others found that Aristarchus and Plato changed in brightness and colour during a lunar eclipse. Aristarchus was especially bright during the lunar eclipse. Cameron 2006 catalog ID=162 and weight=5. ALPO/BAA weight=3.
On 1982 Jan 09 at UT 18:46-21:42 P. Moore (Selsey, UK) and other observers noted Censorinus was exceptionally bright. Cameron 2006 catalog ID=162 and weight=5. ALPO/BAA weight=2.
On 1982 Jan 09 at UT18:46-21:42 Henderson, Sykes and Radley saw an obscuration near Le Verrier - a completely circular halo with dark mare showing through it for a duration of 15 minutes. This was during a total eclipse of the Moon. Cameron 2006 catalog ID=162 and weight=5. ALPO/BAA weight=3.
On 1982 Jan 09 at UT21:37 P. Moore (Selsey, UK) observed that Plato underwent brightness and colour changes, during a total lunar eclipse. At 20:07UT Madej observed a "slight anomaly in Plato". Cameron 2006 catalog ID=162 and weight=5. ALPO/BAA weight=3.
On 1982 Jan 09 at UT 18:46-21:42 M.Mobberley (UK) observed that Schmidt was very bright compared to its surroundings during a total lunar eclipse. Cameron 2006 catalog ID=162 and weight=5. ALPO/BAA weight=2.

On 1984 Dec 07 at UT 19:30-23:30 M. Mobberley (St Edmunds, UK, seeing=IV-V, transparency=good, spurious colour seen) found 2 bright pathces on the east rim on alternate sides of a bright region. The band from the central 16km wide region was dark on the east side. Foley (Kent, UK, 12"reflector, seeing=II-III) found Aristarchus to be not as bright as normal, apart from the band that Mobberley found (1 hour later). The dark regions were a murky green colour (bright through green, blue and yellow filters and dark through red and orange filters). Cook (Frimley, UK, transparency=excellent, CCD camera used) found a bright "bulge"on the eastern side. Apparently data suggests that the band was brighter in red than in near IR light. Cook's calibrated brightness measurements suggest that there was no change in brightness over the crater with time. Two other bright points were seen: one at the Cobra's Head and another half way between the east rim of Aristarchus and passes Herodotus. Wratten 29 (deep red), Wratten 87 (near IR) and combined Wratten 29 and Wratten 87 were used. In the red Wratten 29 filter the brightness falls at22:20 at Shroters valley and then rises in the bright ray. They return to normal at 22:30UT. There was however a lot of measurement noise from the brightness readings of points B and D. The Cameron 2006 catalog ID=256 and the weight=5. The ALPO/BAA weight=3.
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 1953 Jan 29/30 UT 23:00?, 01:00? Dubois (Floirae, France) observed excess luminescence, in Mare Fecunditatis, between 420nm and 470nm (maximum at 435nm) and between 480nm and 520nm (maximum near 505nm). 20-60% during eclipse at 50' from the centre of the umbra, during a lunar eclipse. The cameron 1978 catalog ID=557 and weight=5. The ALPO/BAA weight=4.
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 1953 Jan 29-30 UT 23:05-01:40 G. Brown (UK?) observed a white patch of light of low brightness was seen to move around the north polar area. Coloured bands were also seen on the Moon.

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 1915 Mar 22 at UT 11:30-12:30 Jackson (France?) observed Aristarchus during a total lunar eclipse: "Dur. totality there remained vis. to the NW a red luminous pt. not much larger than Mars & of the same color". (date & time is old system and has been converted by Cameron). The Cameron 1978 catalog ID=343 and the weight=3. The ALPO/BAA weight=3.

On 1895 Mar 10 L. Swift et. al (Lowell Observatory, Flagstaff, AZ, USA) and Elger et al. (England), observed during a total lunar eclipse that Aristarchus was glowing with brilliance never seen before. This attracted everyones attantion. It extended its radiance to adjecent craters (e.g. Herodotus) all throughout totality. At the subsequent eclipse in September 1895 it was seen to be inconspicuous. the Cameron 1978 catalog ID=283 and the weight=5. The ALPO/BAA weight=4.

On 1989 Feb 20 at UT 16:55 G. Kolovos (Thessolonki, Greece) photographed in one photograph (out of 3) during a lunar eclipse, some bright patches below (south?) of the crater that were not in the other photographs (UT16:56:32 or 16:58:56). Foley commented that the photographs were grainy so cannot tell for sure. The Cameron 2006 catalog ID=356 and the weight=1. The ALPO/BAA weight=1.
On 1967 Apr 24 at UT 11:47-12:08 Osawa (Hyogo, Japan, 6" reflector, x50) observed during totality, two luminescent spots (started 20 min after beginning of totality) near Grimaldi. Location not certain because of dimnesa of umbral shdaow and lunar features. (bright spots in Sven Hedin?). Colour was bluish rather than yellowish and magnitude < 9. The Cameron 1978 catalog ID=1035 and weight=3. The ALPO/BAA weight=2.
On 1905 Aug 15 at UT 03:30 Rey (Marseilles, France) observed Tycho during a lunar eclipse to be visible, indeed it was described as brilliant during the eclipse (mid eclipse 03:31UT). The Cameron 1978 catalog ID=322 and weight=1. The ALPO/BAA weight=1.

On 2005 Oct 21 at UT 13:07-14:27 R. Gray (Winnemucca, NV, USA, 15cm F/9 refractor, x228, seeing 4-5, transparency 5-6) observed a possible TLP in Macrobius. His report is as follows: "Blinked Macrobius with Wratten Filters Blue 38A and Red 29. Macrobius became almost invisible through the Blue 38A and essentially the same as in white light through the Red 29. The interior of the crater was completely in shadow. The only part of the east wall that was visible was an apparent high point still in the sun and seen as a bright point of light. This faded into darkness before 13:56UT. No sign of any illumination of the east wall crater interior or the interior of the west wall was seen during the observation period. The outer west wall was a rough looking, complicated mix of deep shadow and illuminated sunlit terrain." The observer concluded that there was not a TLP - although he did get a filter reaction, this may have been due to the different densities of the filters? ALPO/BAA weight=2.
Macrobius 1898 Dec 31 UTC 20:00 Observed by Goodacre (Crouch End, England, 12" reflector) "Interior nearly filled with shadow at sunset. Inner E.wall very bright-a distinct penumbral fringe to black shad. cast on it from W.wall. Seen best using high powers. (Firsoff & MBMW give date as just 1895 but must be wrong-phase - see app.ref.)" NASA catalog weight=4 and catalog ID #304. ALPO/BAA weight=2.
On 1989 Aug 20 at UT13:55 M. Lucas (Melbourne, Australia, naked eye) witnessed a "pin-point flash" in the middle of the lower right quadrant of the Full Moon. Foley suspects that this was in the Proclus region? The Cameron 2006 catalog ID=374 and the weight=2. The ALPO/BAA weight=2.
On 1989 Jan 26 at UT 03:45 De Groof (Belgium) noted a white few second long flash from Copernicus crater. The Cameron 2006 catalog ID=347 and weight=3. The ALPO/BAA weight=3.
Aristarchus 1969 Sep 30 UT 04:46-05:10 Observed by Maley, Saulietis (Houston, TX, USA, 16" reflector, x130) "Intermittent blue color on SE wall, verified by others.

On 1991 Jul 31 at UT 07:50 D. Louderback (South Bend, WA, USA, 3" refractor) observed that the south floor of Aristarchus was wellow - "almost gold, spilled over S wall on ray toward Herodotus". Cameron comments that Bartlett often reported a yellow floor but not a spill of the colour over to the external ray. Cameron also comments that Louderback's refractor would refract more in blue light than in yellow, therefore she did not think that it was due to chromatic aberation. The Cameron 2006 catalog ID=431 and the weight=3. The ALPO/BAA weight=2.
On 1991 Jul 31 at UT 07:50 D. Louderback (South Bend, WA, USA, 3" refractor) found that all of Mons Piton was "unusually dark". Points D, C (E and S resp), usually brightest points, but this time were not bright. "Whole mt was as dark as W wall usually is at this time. In violet filter Piton disappeared completely, but was a little brighter in red filter and points D & G showed. Color not seen by eye. No albedo measured. Suggests red event." Cameron rules out chromatic aberation from Louderback's refractor. The Cameron 2006 catalog ID=431 and the weight=3. The ALPO/BAA weight=1.
Plato 1975 Jun 28/29 UT 23:00-01:20. Foley (Wilmington, UK, 12" reflector, seeing, III, good clarity transparency). At 23:00, 00:30, and 01:15 blue was seen on the inner wall:floor southern boundary, and red on the corresponding northern floor:wall boundary. However by 01:20, blue was now on the S-NW floor:wall boundary, and red on the NE-SE floor:wall boundary. Atmospheric spectral dispersion existed in many regions, but did not change like the colours in Plato. Similar appearance craters such as Grimaldi, Schickard, and Riccioli, were checked for a similar change in colour, but no change was noticed in these. ALPO/BAA weight=1.
Aristarchus 1975 Nov 15 UT 06:34 Observed by Rule (Edinburgh, Scotland, 4" reflector x36) "Blue patch in crater (similar to many of Bartlett's obs.?)" NASA catalog weight=2 (low). NASA catalog ID #1383.
Plato 1975 Jun 29/30 UT 23:05-00:30. Foley (Wilmington, UK, 12" reflector, seeing, III, good clarity transparency). At 23:05, blue was seen on the inner wall:floor southern boundary, and red on the corresponding northern floor:wall boundary. However by 00:30, blue was now on the W floor:wall boundary, and red on the E floor:wall boundary. Atmospheric spectral dispersion existed in many regions, but did not change like the colours in Plato. Similar appearance craters such as Grimaldi, Schickard, and Riccioli, were checked for a similar change in colour, but no change was noticed in these. ALPO/BAA weight=1.
On 1991 Dec 28 at UT 02:10 P. Moore (Selsey, UK) could see no detail on the floor of Plato crater. This report needs to be read in context with the comments by Cameron for A.C. Cook's observation of the floor of Plato on 1992 Jan 18 - Cameron 2006 catalog ID=438.
On 1974 Jun 12 at UT0256 an unknown observer noted a dark blob on the northern edge of the floor of Pitatus crater.
Grimaldi 1998 Mar 22 UT05:15-06:00 S. Beaumont (Windermere, UK, 127mm rich field refractor, seeing III, transparency Good) observed that the northern half of Grimaldi seemed much lighter than the southern half. She comments that she has seen this before in last quarter phases, but it was really quite marked how lighter the northern half was on this occasion. The ALPO/BAA weight=1.
Aristarchus 1976 Oct 18 UT 07:42 Observed by Bartlett (Baltimore, MD, USA, 4.5" reflector and 3" refractor, S=3, T=5) "Inner E. wall 6 deg with very large EWBS at 8deg. No viol. color anywhere & floor was gray at 4 deg (very low). C.p. is only 8 deg. At base of c.p. between peak & advancing shadow a very faint but definite red glow was seen. It was also seen later in the 3" refr. Was confined to W.base of peak & no color on E. base tho. carefully searched for. This red glow was unique in his experience of 28 yrs. His obs. thru. col. 223deg saw nothing more unusual." Cameron 1978 catalog weight=4 and ID #1455.
On 1964 Jun 28 at UT 08:20-09:10 Schmidling, St Clair, and Platt (Riverdale, New York, USA, 8" reflector, x256) observed in the Aristarchus, Herodotus, Schroter's valley area: two red spot glows, glimmer, looked like ruby gems. Cameron says that the date was predicted by Greenacre and looked for. The Cameron 1978 catalog ID=817 and weight=5. The ALPO/BAA weight=4.
In about 557AD (Month, Day and UT unknown), Gregory of Tours observed a light on the Moon near the centre. The ALPO/BAA weight=1. Note some say this was during the Dec 11 lunar eclipse.
In 1835 Dec 22 at UT17:00-18:30 Piazzi-Smyth (Edinburgh, UK) at 18:30UT observed near Aristarchus a bright spot of magnitude 9-10 and at 17:00UT Baily (England) observed a star-like point, in Aristarchus. The Cameron 1978 catalog ID=113-114 and the weight=5. The ALPO/BAA weight=3.

On 1989 Feb 09 at UT 19:00 Ashton (Stafford, UK, seeing=V) observed a "green glow in the "peninsular region" of Cape La Place (south of poss. Helicon A?) and brown on the Earthlit limb. Foley (Kent, UK, 12" reflector) noticed a "pin point glow surrounded by blue-green halo" through a blue filter, but not seen through a red filter. He also suspected some brightness variations. He noted that Aristarchus was barely seen and Copernicus was only a faint smudge, presumably because of the bright limb? J. Cook (Frimley, UK) observed a white glow in the Cape region (made up of pin points?) - no other places had a similar effect. P. Moore (Selsey, UK, 12" reflector) reported that nothing unsual was to be seen anywhere on the Moon. M. Cook (Frimley, UK) found a "bright point source near the tip of LaPlace perhaps maupertius D (or LaPlace D?)." This was seen in a blue filter but not through a red filter - the limb was also seen as bright and the cape as a faint patch. Holmes (Lancashire, UK, 30"? reflector or refractor?) although commenting that Aristarchus was a bit dull, could not see the Sinus Iridum glow, North (UK) could only detect the vague presence of Earthshine throug his finder scope, but not in his telecope.

On 1989 Feb 10 at UT 18:15-18:40 Holmes and Wooler (Lancashire, UK, 22cm Newtonian, x155) found Aristarchus to be bright, but so too was Prinz. However in a 2nd observing session at 21:05-21:10 an area near crater both regions werestill visible but fainter. The Cameron 2006 catalog ID=350 and weight=3. The ALPO/BAA weight=1.
On 1989 Feb 10 at UT 19:00? D. Holmes and Wooler (Lancashire, UK) found area near Prinz to be bright, but so too was Aristarchus crater. The Cameron 2006 catalog ID=350 and weight=3. The ALPO/BAA weight=1.
On 1989 Feb 10 at UT 19:00? Edmonds (England) observed a "bright red coppery" colour in the northwestern part of Proclus crater. He checked and found that there was no colour elsewhere, though he still suspects that the effect was spurious colour. Cameron comments that usually blue is seen in the north and red in the south if due to spurious colour. The Cameron 2006 catalog ID=350 and the weight=3. The ALPO/BAA weight=2.
A faint white pinpoint flash seen and also in the same position a whitish glow around the crater. No futher flashes seen after the first one. From UT2117-2130 the glow was still visible but faded making it more difficult to locate. When Foley observed he found Aristarchus not very visible in Earthshine, despite Plato, Grimaldi, and several other features being visible. Both observers used 12" reflectors. Cameron's 2006 catalog Extension ID=124 and weight=0. ALPO/BAA weight=3.
On 1985 Apr 25 at UT 21:34-22:04 H. Miles (England) observed Aristarchus within Earthshine. Foley (Kent, UK, 12" reflector) had observed it one hour prior to Miles and found it to be both dull and blue - with a bright patch west of the crater on Aristarchus Upsilon Mountain. At 21:45UT 6 star-like flashes seen on the floor. They occurred again a few minutes later and repeated at 22:04UT.By 21:45UT the bright patch had gone though. Smith (England) had also apparently seen the flashes and a further glow, albeit more north of the one seen by Foley. Miles confirmed Smith's glow north of Aristarchus. Peters did not see much, indeed found Aristarchus to be quite faint (2130-2141). The Cameron 2006 catalog ID=264 and the weight=3. The ALPO/BAA weight=2.
Curious lack of detail, but this may have been related to the seeing. Of greater interest though was a dark blue splodge where the crater should have been. Shadow seen through this splodge, but no crater rim seen.
Almost certainly the following was spurious colour and not a TLP. Proclus was found to be brighter than Censorinus. Red was seen on the northern inner floor and blue on the edge of the external north rim NNE-NW. The rim to the SW could not be seen. ALPO/BAA weight=1.
On 1981 Mar 12 at UT 19:25-20:30 Butler (of Brixton, UK, using a 10" reflector at 32-64x) noticed that Aristarchus was not visible, although the Earthshine was very obvious. Foley (of Kent, UK, and using 12" reflector) noticed that the crater was only just visible but Plato could definitely be seen. Cameron's 2006 TLP extension catalog ID=125 and weight=0. ALPO/BAA weight=2.
In 1948 Apr 15 at UT 20:00? Vince (England, UK) observed a bright spot, about magnitude 3, in Earthshine, about 30deg north of Grimaldi., on the west limb (90W, 25N). The Cameron 1978 catalog ID=503 and the weight=3. The ALPO/BAA weight=3.
On 1789 Sep 26 at UT 03:30 Schroter (Lillienthal, Germany) observed close beneath Mons Blanc at the west foot, in the dark, a small 5th magnitude, speck of light. Its round shadow was sometimes black, sometimes grey. Cameron suspects that this is the same as her TLP report No. 50. the Cameron 1978 catalog ID=62 and weight=4. The ALPO/BAA weight=3.
