Macrobius 1938 Jun 02 UTC 18:00? Observed by McLeod (England? 5" ? reflector) "Changes in dark areas. (near Proclus where Green saw phenomenom. see #443)" NASA catalog weight=2 (low). NASA catalog ID # 444.
On 1966 Apr 24 at 21:30UT R.Livsey (Scotland, 6" reflector at x275) observed that Aristarchus was "fluorescent" in Earthshine. It is uncertain whether the description of "fluorescent" should be involve this observation being categorized as a TLP, however just for safety it will be assigned an ALPO/BAA weight=1. This was a BAA Lunar Section report.
On 1987 Mar 04 at UT 19:03-19:47 H. Miles (Cornwall, UK, 5" refractor, x30, S=clear) found at 19:03 that Aristarchus was exceptionally bright (even without blocking out the sunlit side of the Moon), being the most easily seen crater on the Moon, and this was despite the sky not yet being dark. The crater had faded by 19:20UT and at 19:47UT Earthshine was no longer visible. CED brightness measurements were made and were less than usual and the inside of the crater may have had a blue/gray colour (unclear from the Cameron 2006 catalog description). The Cameron 2006 catalog ID=299 and the weight=2. The ALPO/BAA weight=2.
Nebulous appearance. Cameron 1978 catalog assigns an ID No. of 12 and a weight of 1. ALPO/BAA catalog assigns a weight of 1.
On 1867 Apr 09 at UT 19:30-21:00 Elger(Liverpool? UK, 4"? aperture telescope) observed that Aristarchus was shining like a 7th magnitude star-like point, becoming fainter, almost extinguished at 9PM. He had seen lights before but never so strong. The Cameron 1978 catalog ID=151 and he weight=4. The ALPO/BAA weight=2.
On 1983 May 17 at UT20:13-20:40 P. Madej (Huddersfield, UK, x38 and x63) found that Aristarchus was normal in appearance, but at 20:19 a blood red disk was seen as bright as a 6th magnitude star. The colour did not vary but the brightness changed from 4 to 8 over a 1.5-3min period, on the south west wall. Foley (Kent, UK, 12" reflector)observed Aristarchus at 22:10 and noted that it had the same rose-violet colour as had been seen by him a day earlier. The Cameron 2006 catalog ID=220 and the weight=0. The ALPO/BAA weight=3.
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 1983 Jan 19 at UT 18:00-19:00 G. Amery (Reading, UK) discovered that Aristarchus could not be seen in Earthshine, this was odd because less prominent features could be seen. Other observers (Moore and Foley) confirmed the very low brightness of the crater. The Cameron 2006 catalog ID=197 and the weight=2. The ALPO/BAA weight=2.
On 1983 Jan 19 at UT 18:00-19:00 G.W. Amery (Reading, UK) found that Messier was difficult to define. The Cameron 2006 catalog ID=197 and the weight=2. The ALPO/BAA weight=1.

Mare Crisium 1989 Jan 14 UTC 19:15 Observed by Hedley-Robinson (Devon, UK, 5" Coude, Antoniadi II seeing, x150) "Floor blinks indicating colour - used a Moon blink device". 2 areas of the floor were affected, The first one was on the far west of Mare Crisium, next to Proclus crater. The second area was in the NNW, but outside the edge of the mare. Other features elsewhere checked but gave no colour reaction. Peters (UK) though did detect colour elsewhere, but his seeing was III- IV. The Cameron 2006 catalog ID=344 and the weight=5. The ALPO/BAA weight=3.
On 1978 May 14 at UT21:30-22:52 P.W. Foley (Kent, UK, 12" reflector, seeing II and transparency excellent, no spurious colour) observed Aristarchus to be very bright in Earthshine and bluish. The CED brightness measuring device gave a very bright reading of 0.9, the brightest he had ever seen ir before was 0.3. Cameron 2006 catalog ID= 29 and weight=3. ALPO/BAA weight=2.

On 1984 Dec 01 at UT 20:00 a British Astronomical Association Lunar Section member (Southam, Warwickshire, UK) found no detail on the floor of Autolycus, despite there being plenty of detail on the floor of Aristillus crater. According to Foley, there should be some detail at this stage of illumination. Grego reports that the observation was from a Society for Popular Astronomy member and they described "a homogeneous grey veil over the 20 km floor of the crater". The Cameron 2006 catalog ID=255 and the weight=2. ALPO/BAA weight=2.
On 1960 Aug? 01 at UT 22:00? an unknown observer detected that Vitello was illuminated -it should have been in shadow? Cameron says that if several days before sunrise then the date could have been July through to December, with August 1st most likely, and ancilary data is therefore given for this date. The Cameron 1978 catalog ID=729 and weight=1. The ALPO/BAA weight=1.
Plato 1979 Apr 06 UT 18:00-21:00 Observed by Crick (Belgium, seeing II- III) Part of floor darker than normal and obscuration on inner west wall - the effect did not change during the observation. Drawing made. Cameron 2006 catalog ID=49 and weight=3. ALPO-BAA weight=2.

A 10 minute exposure spectrum was taken (Cameron does not have information on whether anything unusual was recoeded) before clouds obscured the Moon. Normally a 30 minute exposure would be needed. The Cameron 2006 catalog ID=345 and the weight=3. The ALPO/BAA weight=3.
2007 Oct 20 UT 17:31 A.Pink (Basinkstoke, UK) images a flash on the dark size of the Moon near to Vitello. The ALPO/BAA weight=1.

On 1982 Mar 04 at UT 20:00 M.C. Cook (Frimley, UK) found Proclus (4.0) to be fainter than Censorinus (4.6) in white light. The Cameron 2006 catalog ID=164 and weight=4. The ALPO/BAA weight=2.
Aristillus 1939 Sep 23 UT 01:00 Observed by Haas? (New Mexico?, USA, 12" reflector?) "Dark area in W. part of floor had I=1.3. comp with I= 1.3, 3.7, 4.0 in #450, 454, & 459, respectively. (albedos disagree at same phases, so are real anomalies). (normal here?)." NASA catalog weight=4 (high). NASA catalog ID #461.
On 1987 Mar 09 at UT20:00 M. Mobberley (Sussex, UK) obtained some video of Mons Pico - apparently these show the mountain with a puzzling appearance (not sure whether it was the observer who claimed this or some one who analyzed the tape). The Cameron 2006 catalog ID=300 and the weight=5. ALPO/BAA=1.
Alphonsus 1966 Apr 20 UT 22:28 Observed by Smith (Nottingham, England, 10" reflector) Reddish patch possibly detected on SE flank of central peaks, but more dubious than that from 28th Apr. ALPO/BAA weight=1.
On 1964 Jan 24 at 20:00? Scarfe (UK) obtained spactra showing luminescence? The Cameron 1978 catalog ID=796 and weight=5. The ALPO/BAA weight=3.
C. Brook of Plymouth UK, using a 4" refractor x216, noticed at UT 20:10 dark patches coming and going (in terms of visibility) on the floor of Plato. Occasional views of the central cratelet (seen as a white spot) were glimpsed. The dark patches seen lasted about 1-2 seconds before fading out during each visibility cycle. Teneriff Mountains were checked but no sign of seeing effects that might explain the dark floor patches. By 20:26UT the dark patch effect was fading and by 20:31UT floor detail was visible. Observations ceased at UT 20:34. Seeing conditions were II and the Moon was at a high altitude. Other observers were alerted but came on-line after the effect had finished. ALPO/BAA weight=2.
At approximately 18:43UT observer noticed that Censorinus, and its bright apron, appeared particularly brighter than normal. There was some spurious colour present - but just a redness along the southernmost extent of the apron visible; could not detect any blue along the northern edge however, he did do not suspect the colour to be anomalous. A re-examination at 18:51UT revealed that the crater had faded and was seen to fade visibly in real time to normal levels (over about a minute) by 18:53UT. Other features remained constant and so too did the apparent spurious colour.
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." N.B. event had finished by the time Corralitos came on-line. NASA catalog weight=5. NASA catalog ID #931. ALPO/BAA weight=4.
Eratosthenes 1968 Nov 01 UT 01:50-02:06 Observed by Chilton (Hamilton, Canada, 12" reflector, 300x) "Red glow in the crater. Weak blink beyond ESE (IAU?) wall. Visually, area would not focus & gave impression of fog cascading down slope, but no motion was vis. (Moore has misprint in time in his cat. extension -- should be 0150-0206)." NASA catalog weight=3. NASA catalog ID 1106. ALPO/BAA weight=3.
Sinus Iridum 1996 Apr 28 UT 20:00 Observed by Brook (Plymouth, UK, 60mm refractor, x112, seeing III, slight breeze, twilight) "dark shaded area on floor ~1/4 diameter of Sinus Iridum on western interior by rim" BAA Lunar Section Observation. ALPO/BAA weight=1.
Bulialdus 1979 Aug 03 UT 21:36-21:48 Observed by Cook (Frimley, UK, seeing III, Moonblink device) "Bullialdus eastern side of the crater looked brighter in red i.e. rim and exterior, extending to the south slightly and this reddish areas was slightly hazy. At 21:41 it clouded over but at 21:47-21:48 it cleared briefly and effect was noted again. Also Darney appeared very visible through the red filter. Probably spurious colour as the Moon was -18 deg in declination and the whole Moon had a slight brownish tinge" ALPO/BAA weight=1.
Darney observed by Cook (Frimley, UK, seeing III, Moonblink device) See TLP report for Bullialdus (eastern side) concerning reddish areas. At 21:41 it clouded over but at 21:47-21:48 it cleared briefly and the effect was noted on Bulialdus again. Also Darney appeared very visible through the red filter. Probably both effects were spurious colour related as the Moon was -18 deg in declination and the whole Moon had a slight brownish tinge. An ALPO/BAA weight of 1 is assigned to this TLP."
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 1984 Jan 14 at UT 20:00 P. Moore (Selsey, UK) observed that Aristarchus was brighter than it normally is at sunrise. No quantitative measurements were made though. The Cameron 2006 catalog ID=238 and weight=3. The ALPO/BAA weight=1.

Corralitos MB did not confirm. - but they may not have been observing at the ame time?)." NASA catalog weight=5. NASA catalog ID #932. ALPO/BAA weight=4.
On 1978 May 18 at UT20:45-21:53 J.D. Cook (Frimley, UK, 12" reflector, x240) observed Promitorium Laplace to have visually a brown colour - though no Moon Blink (red and blue filters) effect was detected. Cameron comments that this is probably a subjective effect - also others have reported something similar at times. The Cameron 2006 catalog ID=30 and weight=3. The ALPO/BAA weight=1.
Plato 1998 Jul 05 P. Moore (Selsey, UK, 15" reflector, x200- x400, seeing II/III) comments that he is puzzled why the floor of Plato, which is light gray in shade, looks completely blank tonight. The ALPO/BAA weight=1.
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.
M. Cook of Frimley, UK observed a brightening of the crater during this observing session. The cameron 2006 extended catalog ID=346 and weight=3. ALPO/BAA weight=2.

Gassendi 1939 Sep 25 UT 01:30 Observed by Haas (New Mexico? 12" reflector?) "NE part pf c.p. had I=9.4 comp. with I=6.4 (normal? in # 458. under similar obs. cond. (& phase. thus real diff.)" NASA catalog weight=4 (high). NASA catalog ID #462.
Gassendi 1967 Mar 22 UTC 19:39-19:43 Observed by Mosely (Armagh, N. Ireland, 10" refractor, x360) "Red color & blink strongly suspected in small area centred on junction of 3 clefts 1/2 way from c.p. & ESE wall. Well-defined & did not note change during obs. period. Clouds terminated obs. till 2120 when it was not seen." NASA catalog weight=3 (average). NASA catalog ID #1018.
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.
G. Ward (a lunar observer for 15 years) observed an area just south west of Mersenius C to be blurred and in a greenish cloud. The green colour was more like that of dead grass than one gets from a neon bulb. The effect was seen from 04:50-04:57UT, but could have been going on before it was first noted at 04:50-UT. Seeing was 6-7/10 4" Refractor (2 element). refractor had been used hundreds of hours before (over a 10 year period) with no similar colour was seen. The observer checked other areas but did not see any similar effects. They also rotated and changed eyepieces, but this made no difference to the TLP. The TLP site seen was picked up on an image taken earlier at 04:47UT by W. Bailley, from Sewell, NJ, USA. Unfortunately the area concerned, a mountain on the image, was saturated and so we cannot tell if a colour was present there and the seeing was poor.
Aristarchus 1975 Oct 16 UT 20:00? Observed by Foley (Kent, England, 12" reflector) "Deep blue-viol. spot in NW (IAU?) interior corner." NASA catalog weight=3. NASA catalog ID # 1413. ALPO/BAA weight=1.

P. Foley of Kent, UK, using a 12" reflector, seeing=III-II, noticed that initially that the crater was pretty dull and that the floor was a slate blue-gray in colour at 22:45UT. A noticeable green spot inside the crater on the south east appeared at 22:25UT and vanished at 00:50UT. Cameron notes that one doesn't get green with spurious colour. Crater Extinction brightness measurements were made at 22:00 UT (reading=2.8) and at 23:45UT (reading=3.7). The crater dropped in brightness from 3.7 to 2.8 at 23:50UT and remained lower until 3.0 at 23:50-03:15 UT. A graph was produced and showed Proclus and Censorinus at similar brightnesses, but Aristarchus variable. The Earthshine was 0.3. Cameron 2006 Extension catalog ID=31 and weight=5. ALPO/BAA weight=3.

On 1988 Sep 23 at 19:40-19:55 & 20:36-20:41 G. North (760mm Coude Rrefractor, x250, Royal Grenwwich Observatory, Herstmonceux, UK, seeing V, Transparency: Fair). 19:40-19:55 image very unsteady. All seems normal in other crtaters with the exception of Arcimedes. Much of the rim seems indistinct apart from a 1/4 length of the west rim. Strongly suspected that this was due to a combination of seeing and illumination. UT 20:02-20:06 - checked the area with a lower magnification 10" Astrographic Refractor - the crater seems more normal, so suggesting that the theory was correct. 20:36-20:41 returned to the 30" reflector, and the crater appeared similar to the start of the session. This is almost certainly not a TLP, but it would be helpful to have some images or sketches to check this theory out. Weight=1.
On 1987 Mar 13 at UT02:00-03:00 De Groof (Belgium, 8" reflector x150, seeing=clear) noted that the north west part of Aristarchus had a blood red shimmering filling the whole crater. A video by Mobberley some 18 hours later, shows variation in Aristarchus. Cameron 2006 catalog ID= 301 and weight=5. ALPO/BAA weight=3.

Plato 1981 Jun 15 UTC 21:30 Observed by Amery (Reading, England, 25cm reflector, seeing Antoniadi IV-V) At the 4 O'Clock position on the North West corner?, there was a dark smudge which reached from the floor across and over the wall and onto the terrain outside the crater. Foley, alerted by Amery, saw a dark show-like patch in the crater's north west corner, again lying across the rim. 2006 Cameron catalog extension ID=148 and weight=4. Foley used a 12" reflector and seeing was III-V. ALPO/BAA weight=3.
On 2009 Jan 09 at UT 20:00 P. Brierley (UK) took a CCD image of the Aristarchus area - P.Grego upon examining this comments that he thinks that Schiaparelli crater looked "muted in brightness -- it is normally quite bright to look at". Though Grego comments that it might have something to do with the image processing aplied to the image. The ALPO/BAA weight=1.

On 2009 Sep 03 at UT23:15-23:17 B.Gibbs took some hand held digital SLR images of the Moon (Sky conditions clear). Four images were taken at: 23:14:53, 23:15:59, 23:16:05 and 23:17:23 (uncertainty +/-15 sec offset from actual UT). These showed some apparent variation in the brightness of Aristarchus. However there are ways toexplain this through image motion blur when the images were taken. However we cannot be absoultely sure. The ALPO/BAA weight=1.
Aristarchus 1961 Jun 27/28 23:00?-01:00? Observed by Granger & Ring (Italy). "Enhancement of Spectrum in UV at CaII similar to May obs." NASA catalog weight=5. NASA catalog ID #741. ALPO/BAA weight=3.

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.
Proclus 1955 Aug 03 UTC 04:13-04:40 Observed by Bartlett (Baltimore, MD, USA, 5" reflector, x180, S=5, T=5) "Floor blackish 2 intensity but in green filter assumed a distinctly mottled or flocculent appearance -- seen only in green.

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.
F. Graham took some photos of the Cobras Head and found a blue cloud about 50 km in diameter and scattering light - Cameron says that this indicates high density. Darling found the Cobra's Head obscure and variable "clear and bright to diffused". Cameron was alerted observed (02:40UT) variations with periods of approximately 30 seconds, and thought that she could see a red tinge on the east rim of Aristarchus - checks elsewhere found no other colours. Darling found that a blue filter enhanced the effect and a red filter made it disappear. There was a blink at 02:55UT but no blink in the Cobra's Head, which looked fuzzy and lacking in detail. The effect was confirmed by Weier, who also saw two dark spots in the Cobra Head in blue but not in red light. The brightness of the Cobras Head was 6.0, Herodotus floor 5.5, NW wall 7.5, South wall, 7.0, Aristarchus south wall 9.0, west wall 9.0, south wall 7.0, East wall 8.0, and the central peak 10.0. Observer details were as follows: Darling (Sun Praire, WI, USA, 12.5" reflector, x159, S=9/10). D. Weier (Sun Praire, WI, USA, 12.5" reflector, x159, S= 9/10), W. Cameron (Sedona, AZ, USA, 8" reflector x110 and x220, T=6 and S=6) F. Graham (E.Pittsburgh, PA, USA, 7" refractor, thin haze). Cameron 2006 catalog ID=415 and weight=5. ALPO/BAA weight=4.
On 2000 Jun 15 UT 20:37 C. Brook (Plymouth, UK, 60mm refractor, x117 & x40, seeing good, transparency excellent) observed abright spot on the north rim of Mare Crisium (57E, 25N). It was comparable to the illuminated rim of Proclus in brightness. No colour seen. The spot was not visible the next night. The ALPO/BAA weight=1.
Proclus 1972 Nov 20 UT 20:20 Observed by Farrant (Cambridge, England, 8.5" reflector, x178) "Dark patch in crater. Disappeared by next nite. The normal ring seemed thickened. On Dec. 7. the crater appeared bright. Drawings. (prob. real LTP, nr. FM)" NASA catalog weight=3 (average). NASA catalog ID #1350.
Near Censorinus 1964 Apr 26 UT 20:00? Observed by Hopmann (Czchoslovakia?) "Surface brightening somewhat similar to Kopal and Rackham in #779" NASA catalog weight=3 (average). NASA catalog ID #810.

On 1989 Oct 14 UT 19:00?, 22:00? P.W. Foley (Kent, U.K., using a 12" reflector) noted that although the brightness of Aristarchus crater seemed steady, that there was just too much detil to see inside the crater than one would expect. Appeared as two craters - Cameron commented that this was often seen by Bartlett. Several observers apparently confirmed this TLP? Cameron 1978 catalog extension ID=379 and weight=5. ALPO/BAA weight=2.
Aristarchus was not normal, but all the following features were: Mare Crisium, Proclus, Sinus Iridium, Grimaldi, and Tycho. Observed by Mellor and Fitton, UK. Observer notes that Aristarchus is brighter than Tycho when normal. Estimated variation was 25%. However the Moon was low and the Moon was yellow. Despite this the observer decided that the effect was real. Cameron 2006 extension catalog ID=32 and weight=2. ALPO/BAA weight=1.
Proclus 1958 Aug 30 UT 06:30-06:45 Observed by Bartlett (Baltimore, MD, USA, 4" reflector, x240, S=6, T=5) "Proc. Q. a bright spot on NE rim apparently a crater presented a very abnormal aspect.

Cobra Head 1955 Oct 31 UTC 19:00 Observed by Milligan (England?) "Dark blue obscuration" NASA catalog weight=3 (average). NASA catalog ID 624.
Mobberley noticed that Torricelli B was bright and had an even brighter spot on the inner north wall. The observation was made from UT19:45- 21:40 using visual and video techniques. There was also a bright region NNE of Toricelli B, that was noticed. Foley examined the video and found that the crater faded in brightness over time and also the bright area to the NNE was not as bright on video as had been seen visually. Foley speculates that because the CCD camera was sesnitive to the near IR that maybe the spot was blue?. Foley observed from 21:12-21:21UT and also saw the bright spot on the inner north wall - but saw a blue halo around the crater. Response in blue filter, darkening over whole region. Brightness measures with a crater extinction device (CED) indicated that the crater was 80-85% the brightness of Censorinus. There was a bright area NNE of the region. M. Cook observed 22:10- 22:16UT (15cm reflector and seeing III-IV) and also saw that the crater was very bright indeed with a spot NNE of the region (same position as 28/28 1985 observation) - suspected that the crater might have been brighter than Censorinus, but judgement effected by seeing. In a blue filter the crater dulled leaving the bright spot prominent (but only during a good moment of seeing) - therefore had some suspicion of seeing effects. At 01:00-01:04UT M. Cook used a 12" reflector on the area, but the seeing was even worse - but did manage a check of the brightness of Torricelli B to Censorinus and now made it one quarter of that of Censorinus and no sign of the crater dimming in the blue as had been seen earlier in the 6" refletor. A. Cook (Frimley, seeing V) at 21:15UT (Dec 27) thought that Torricelli B looked normal and saw no colour. At Dec 28 at UT 00:02-00:25 A. Cook obtained some CCD images through red+IR (Wratten 25) and IR (Wratten 87) but found no colour differences, though there was a very slight hint that a brightness fade may have occurred between those two observing times. Note that this report does not have an entry in the Cameron 2006 Extension Catalog. The ALPO/BAA weight=4.
On 1983 Jan 29/30 at UT20:35-01:00 Sykes (UK?) observed that Linne appeared to brighten for approximately 20 min and had the appearance of a point (confirmed). This observation was made during a major Torricelli B TLP. The Cameron 2006 catalog ID=198 and the weight=5. The ALPO/BAA weight=2.
Torricelli B 1983 Jan 29/30 UTC 20:35-02:30 Observed by Foley (12" reflector, seeing Antoniadi II, Transparency=good, no spurious colour seen), Moberley (14" reflector, seeing Antoniadi II, transparency excellent, spurious colour strong), Cook, J & M (12" reflector, seeing Antoniadi II-III, transparency moderate). All observers based in southern England. "Initially crater brightest feature on the Moon, then it faded. Strong colour also seen by all observers e.g. green-blue to violet. Report of observations written up in JBAA Vol 100, No. 3, p117 123, (2000) - probably one of the best reorted TLP". The Cameron 2006 catalog ID=198 and weight=5. The ALPO/BAA weight=5.
On 1983 Jan 29 at UT22:09 M.Mobberley (Sulfolk, UK, 14" reflector) noted that Arago B had a slight tinge of violet colour, and was a lot less (bright?) than Torricelli B's blueness. Other craters checked but were not showing any blue colour. The Cameron 2006 catalog ID=198 and weight=5. The ALPO/BAA weight=3.
On 1983 Jan 29 at UT22:09 M. Mobberley (Suffolk, UK), found that Moltke crater was "exceptionally bright". Other craters (apart from Arago B Torricelli B etc) appeared normal. The Cameron 2006 catalog ID=198 and the weight=5. The ALPO/BAA weight=2.
Proclus 1972 Nov 21 UT 21:30 Observed by Farrant (Cambridge, England, 8.5" reflector, x130) "Thickened bright ring remained, but the dark patch had disappeared. (dark patch prob. real temporary phenom. as it was seen nr. FM when contrasts are strongest, yet disappeared" NASA catalog weight=1 (very low). NASA catalog ID #1351.
On 1983 May 28 at UT 01:50-03:00 K. Marshall (Medellin, Columbia) observed the whole region of Aristarchus, Herodotus and Shroter's Valley all to have a brightness of 3 and all blue and impossible to focus on (he had never seen it like this before). Also the interior of Aristarchus was invisible. Brightness measurement taken and a sketch was made. The Cameron 2006 catalog ID=222 and the weight=3. The ALPO/BAA weight=3.
CCD images taken through Wratten 25 (red+near IR) and 87 (near IR only) filters. Between 00:02 and 00:25UT there was some slight evidence that a fade may have taken place however careful analysis by Cook casts doubt on this. Probably it was more related to a degradation in image quality due to seeing than a true TLP. An ALPO/BAA weight of 1 has been assigned.
Proclus 1958 Jul 03 UT 06:18-07:15 Obsrved by Bartlett (Baltimore, MD, USA, 5" reflector, x180, S=5, T=3) "Proc. C a remarkable phenom. of which he is certain. At beginning of obs.

East of Plato 1961 Jun 29/20 23:00?-01:00 Observed by Granger and Ring (both in Italy) "Enhancement of spectrum in UV & Ca I recorded on photoelectric spectrometer scans" NASA catalog weight=5. NASA catalog ID #742. ALPO/BAA weight=3.
On 1990 Dec 03 at UT23:00-01:30 M.C. Cook (Frimley, Surrey, UK) noticed that the central peak of Aristarchus was quite bright and extended to a circular region in the east in the crater "sprout" area - Cameron suggests that this is Bartletts self defined EWBS area?. Beyond the rim to the east was very bright. However no colour effect was seen in filters. A sketch was supplied. Cameron notes the coincidence of perigee and full Moon. The Cameron 2006 catalog ID is 416 and the weight=3. The ALPO/BAA weight=1.

On 1985 Dec 29th at UT 23:23-23:58, M. Mobberley (Bury St. Edmunds, Suffolk, UK, seeing II-III) made a video scan of the Moon. P.W. Foley examined the tape and noted something that Mobberley had not seen visually. Two scans of Totticelli B had taken place, one at 23:23 and the other at 23:58UT. In the first a brilliant point appeared briefly, on the western rim, positioned at 3o'clock. In the second video sequence this brilliant spot was present continuously and wandered along the rim. It was possible to monitor frequency of turbulence present, this apparent movement did not ppear to conform, although judgement here was extremelydifficult as the feature was at absolute point of resolution, a little better than 0.5 mile. Also considered was the implication of the equipment effect, this did not seem to fit either as other nerby craters in the same configuration, 30% shadow filled with sunlight on exterior of western walls. A point to watch for in future. ALPO/BAA weight=3.

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.

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.
