On 1988 Aug 28 at UT22:00 P.Moore (Selsey, UK, 5" refractor, x260) detected a red glow along the outer wst rim and 99% it was not a TLP as there had been a fire nearby so was probably atmospheric. However colour if present, is normally seen on the south rim. The Cameron 2006 catalog ID=336 and the weight=1. ALPO/BAA weight=1.
On 1967 Apr 26 at UT 03:00 Kozyrev (Crimea?, Soviet Union) observed Gas luminescence in Aristarchus crater. The Cameron 1978 catalog ID=1069 and weight=3. The ALPO/BAA weight=3.

On 1986 Apr 26 at UT 21:00 etimated) H. Miles (Cornwall?, UK) found that Aristarchus was "still brighter in moments of better seeing". The rim could be seen as a complete circle. The Cameron catalog ID=283 and the weight=3. The ALPO/BAA weight=1.
Furnerius A 1983 Jan 02 UT 00:10 H. Hill (UK) observed that this crater was piercingly bright, which he thought was a bit unusual. ALPO/BAA weight=1.
Messier A 1951 Aug 20 UT 01:48-03:00 Observed by P.Moore (England, 8.5" reflector, x350). Bright cloud like circular patch seen on S wall of Messier A. It was the brightest object in the vicinity. 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.
Plato 1938 May 17 UTC 08:00 Observed by Haas? (New Mexico?, USA, 12" reflector?) "Floor-least bit greenish (other colors on other dates, e.g. Je 23, 7/22/37, & 7/15/38)." NASA catalog weight=3 (average). ALPO/BAA weight=2. NASA catalog ID #437.
Cleomedes 1991 Dec 23 UTC 22:50 Observed by Mizon (Colehill, Dorset, UK, 8" f/6 reflector x216) "Oval or pear-shaped ashy glow visible for 2 min, then vanished quite suddenly" - Ref. personal communication received by BAA Lunar Section.
Proclus 1973 Jan 21/22 UTC 23:57-00:25 Observed by Muller (located at 51.42N 8.75E) "Proclus much brighter than Cenorinus" 50mm refractor used. Ref Hilbrecht & Kuveler (1984) Moon and Planets Vol 30 p53-61.
On 1979 Sep 09 at UT08:00-08:15 D. Darling (Sun Praire, WI, USA, 12.5" reflector, x75 and photography used, seeing 4/10 and the Moon's altitude was 45deg) photographed Romer crater and recorded two adjacent bright cigar shaped objects - these were the same size as an observation made in 1987. Darling believes that these are ridges. Cameron comments that in LO-IV 192-3,2 a ridge is revealed on the inside wall that matches the description. Cameron 2006 catalog ID=66 and weight=2. 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 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.
Callipus 1952 Sep 09 UT 21:00-21:20 Observed by Moore (England) "Hazy broad line of light seen fr. NW wall to SE wall over shad. floor. Gone next nite at 0120. He gave low wt. to obs. (sunlight between peaks?)." NASA catalog weight=1. NASA catalog ID #553. ALPO/BAA weight=1.
Ptolemaeus 1825 UT 23:45 Observed by Schwabe (Germany?) "Bright spot" NASA catalog weight=4 (high). NASA catalog ID #108. ALPO/BAA weight=3.
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 1916 Jan 27 at 22:00? Markov (Russia) noticed that a light sector was visible at the bottom of Plato, in shadow, and contained 3 bright spots, reminiscent of phfescent bodies. The Cmaeron 1978 catalog ID=362 and weight=3. The ALPO/BAA weight=3.
On 1983 May 15 at UT20:30-21:05 P.W. Foley (Kent, UK, 12" reflector) was unable to see Aristarchus in Earthshine, though other craters were clearly visible. However by 21:30 the Cooks could clearly see Aristarchus. The Cameron 2006 catalog ID=215 and the weight=0. The ALPO/BAA weight=2.
W.limb 1983 May 15 UT 20:30-21:00 R.Moseley (Coventry,UK, 6" reflector, x60) observed a faint but extensive brightening of the W.limb, perhaps a little stronger at PA=80-90 deg. No other features seen in Earthshine. Observation confirmed br R.Martiott (Northampton, UK, 8.5" reflector). ALPO/BAA weight=1.
On 1987 May 03 at UT 19:00-19:30 H. Miles (Cornwall, UK, 5" refractor, x30) found the Earthshine to be both pink and bright with prominent features clearly visible. A "brilliant" star-like point was seen in Aristarchus crater. There was another, albeit less bright spot near Darney-Agatharides. Spots pesisted despite various tests. Foley also confirmed that the Moon looked pink to him as well. The Cameron 2006 catalog ID=298 and weight=1. The ALPO/BAA weight=1.
On 1987 May 03 at UT 19:00-19:30 H. Miles (Cornwall, UK, 5" refractor, x30) found the Earthshine to be both pink and bright with prominent features clearly visible. A bright spot was seen near Darney- Agatharides. An even more "brilliant" star-like point was seen in Aristarchus crater. Spots pesisted despite various tests. Foley also confirmed that the Moon looked pink to him as well. The Cameron 2006 catalog ID=298 and weight=1. The ALPO/BAA weight=1.
Boussingalt 1856 Apr 08 UT 20:00? Observed by Schmidt (Athens, Greece, 7" refractor) "Noted weak glows in the crater he tho't prob. due to wall reflections on the floor" NASA catalog weight=0 (not very likely to be a TLP). NASA catalog ID #131. ALPO/BAA Catalog weight=1.
On 1991 Dec 09 at UT 22:50 D. Darling (Sun Praire, WI, USA, 3" refractor, x36) witnessed a flash in Grimaldi crater. Cameron comments that others had seen a flash there earlier, and there was a meteor swarm. Fritschel (madison, WI, USA, naked eye observing) detected 3 flashes in Grimaldi and also at the western limb of the Moon. D. Weier (Sun Praire, WI, USA, 3" refractor, x36) was also observing. The Cameron 2006 catalog ID=436 and the weight=5. The ALPO/BAA weight=2.
On 1983 May 15 at UT21:30-22:30 M.C. Cook and J.D. Cook (Frimley, UK) could clearly see Aristarchus in Earthshine, whereas earlier that night P.W. Foley (Kent, UK) could not see the crater although other features were cisible. The Cameron 2006 catalog ID=215 and the weight=2. The ALPO/BAA weight=1.
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 1983 May 16 at UT20:35-22:10 P.W. Foley (Kent, UK) noted that Aristarchus was dull in Earthshine (UT21:36-21:40). The floor was a luminous rose/violet colour. The Cameron 2006 catalog ID=219 and the weight=0. The ALPO/BAA weight=1.
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.
On 2009 Jan 30 ay 22:35:20UT +/-2 min R. Masini (Perth, Australia) saw a bright clound just west the south pole and along of the southern limb. The effect lasted a few seconds and faded. It was seen with the naked eye. There was a grazing occultation of a 6th magnitude star from this site, however the star would have been in the wrong place at the time of the TLP. The ALPO/BAA weight=2.
W.limb 1983 May 16 UT 22:00-23:00 R.Moseley (Coventry,UK, 6" reflector, x60) observed a faint but extensive brightening of the W.limb, perhaps a little stronger at PA=80-90 deg. No other features seen in Earthshine although Aristarchus suspected. ALPO/BAA weight=1.
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.
Daniell 1979 Apr 02 UT 21:45-22:14 Obseved by Madej (Huddersfield, UK, 158mm reflector, f/4.2, x36-110, seeing II-III) "Obscuration seen" BAA Lunar Section Report. Cameron says that this was a bright white cloud that covered three quarters of the crater. A yellow filter was used at 21:48, but the cloud was still white, albeit thinner (at x110). By 22:14UT the TLP was barely visible and again no colour seen. Buczynski (Lancaster, UK, seeing = poor) saw spurious colour. Later (22:31- 22:46UT?) Mellor obtained some photos, but these revealed no colour. The Cameron 1978 catalog ID=48 and the weight=3. The ALPO/BAA weight=2.
On 1983 May 17 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=2.

On 2000 Feb 11 at UT19:00 G. North (Norfolk, UK) telephoned TLP coordinator, Patrick Moore, to report a possible colour anomaly in Aristarchus. Moore had poor conditions in Selsey (UK) and saw nothing unusual. However by this time North was reporting that, the colour was fading. Two other BAA members were alerted, but were clouded out. The ALPO/BAA weight=3.
1968 Apr 04 UT 18:45-19:20 Observed by Darnella (Copenhagen, Denmark, 6" refractor, x183) "Small area just E(ast.) of Menelaus was seen with a reddish color which gradually faded.

On 1983 May 20 at UT00:00-03:00 K. Marshall (Medellin, Columbia) noted that Mons Piton was too bright near the terminator and was surrounded by shadow. A sketch was made. The mountain appeared segmented with one thin shadow line. The mountain looked like a Mexican Sombrero hat. This appearance is normal. What was abnormal was that Piton was brighter than Proclus, and only slightly fainter than Censorinus. The CED brightness measurements were normal Piton=3.6, Proclus=3.5 and Censorinus= 3.7. Please check to see whether this is still the case. The cameron 2006 catalog ID=221 and the weight=3. The ALPO/BAA weight=1.

Alphonsus 1990 Feb 03 UTC 20:05-21:22 Observed by Brook (Plymouth, UK, 10" reflector) "Brightness variance noted". The Cameron 2006 catalog does not have an entry for this observation. The ALPO/BAA weight=2.
Tycho 2003 May 09 UT 21:04 Observer Brendan Shaw (UK) "CCD image of central peak - Sun's altitude suggested that this should not have been directly illuminated this early - may have been from secandary reflectance off illuminated W wall?" ALPO/BAA weight=1.
At 03:00UT(?) Evrard et al from the western US(?) saw somewhere a reddish glow, followed by black obscuration. The date in the Middlehurst catalog is 18/1/65, but there may have been a descrepency between local time date and UT date? Cameron 1978 catalog TLP No=916 and weight=3.
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 1982 Jun 30 at UT 02:05-02:15 Marco Petek (Porto Alegre, Brazil) found that the region between Eratosthenes and Bode (7W, 13N) looked like it had a darkening (cloud?) that had even darker points inside. The Cameron 2006 catalog ID=172 and weight=3. The ALPO/BAA weight=2.
Alphonsus 1968 Apr 06 UTC 20:30-21:15 Observed by Wise (Slough, England, 17" reflector x190, x350, S=E" Suspected glow inside W.(ast?) wall at 2038" NASA catalog weight=1 (very low). NASA catalog ID #1066.

On 1931 Mar 27 R.Barker (observing from Cheshunt, UK, 12.5" reflector) found that the central mountain in the brilliant ray crater Tycho was a curious shade of grey. This was despite the interior of Tycho being fully in shadow. Cameron 1978 catalog ID=400 and weight=3. ALPO/BAA weight=3.
Tycho 2003 May 10 UTC 03:15 Observer Robert Spellman (Los Angeles, USA) - "CCD video of spur-like features coming off N & S edges of central peak - spurs pointed eastwards". It is now thought that this effect is almost certainly seeing flare as it is visible on other features in the image, although to a much lesser extent. The ALPO/BAA weight=1.
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.

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 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.
1864 May 15-16 UT 23:00-01:00? East of Picard (probably Curtis Observed by Ingall (Camberwell, England?) "Remarkable bright spot" NASA catalog weight=3 (average). NASA catalog ID #134. ALPO/BAA weight=3.
On 1982 Jul 01 at UT 02:23-02:58 Robotham (Springfield, ON, Canada, seeing=II) found that the west rim of Pytheas crater was a very bright yellow-white, indeed brighter than Proclus. At lower magnifications, Pytheas was one of the brightest spots on the Moon. The Cameron 2006 catalog ID=173 and weight=2. ALPO/BAA weight=2.
Piton 1958 Sep 23 UT 00:00? Observed by Moore? (UK?) "Enveloped in an obscuring cloud-like mist" NASA catalog ID 697. NASA catalog weight=2. ALPO/BAA weight=2.

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 22:00 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.
Ross D 1965 Dec 04 UT 04:25 Observed by Cross (Whittier, CA, USA, 19" reflector, x155, seeing 4+) "Obscuration of part of the rim, also bright area 7-10km diam. Not seen on following nite." NASA catalog weight=4 (good). NASA catalog ID #917. ALPO/BAA weight=3
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."
W. of Mare Humorum (50W, 25S) UTC 00:00? Observed by Mac Farline (England?) "Bright Point" NASA catalog weight=2 (low). NASA catalog ID 719.
In 1820 Oct 17 at UT 20:00 an unkown observer reported in Mare Imbrium, south of Sinus Iridum (30W, 40N) some brilliant spots. The Cameron 1978 catalog ID=80 and weight=1. The ALPO/BAA weight=1.
Gassendi 1977 May 28/29 UT 20:45-21:15 Observed by D. Sims (Dawlish, Devon, UK) saw a hazy area on the south east floor that was normal in red and white light but darker in blue. This was partly confirmed by J-H Robinson (Devon, England, 10" reflector) 21:24-23:12 who saw the south east floor of Gassendi to have a loss of detail - but no colour seen, although at 21:57-21:58 it was slightly brighter in red than in blue briefly. P. Doherty (22:45-23:15) did not see anything ususual. D. Jewitt (22:22-22:55) did not reveal anything ususual, apart from spurious colour. The Cameron 1978 catalog ID=3 and ID=1463. The ALPO/BAA weight=3.
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.

Brown saw intense white spot NW of crater wall" NASA catalog weight=5. NASA catalog ID 933. ALPO/BAA weight=4.
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 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.

On 1965 May 12 at UT 19:10 E. Penzel (Rodewisch, East Germany) was taking a sequence of images during the impact of the Soviet Lunik 5. He detected a tens of km scale elongated cloud after the impact over a duration of 9.5 minutes. However there are differences between the images elsewhere on the Moon, possibly due to different exposures or some other effects and it is not 100% sure that what he detected was impact debris/cloud?. The ALPO/BAA weight=3.
On 1933 oct 01 at UT 03:00 Rawstron (USA, 4" refractor, x330) observed the following in Mons Pico B: "Haze -- much narrower & elongated than on Sep. 1". The Cameron 1978 catalog ID=407 and weight=3. The ALPO/BAA weight=2.
Observed by Haas (Las Cruces, NM, USA) "Temporary greyness seen in interior shadow." ALPO/BAA weight=3.
On 1955 Oct 28 at UT00:00? Kozyrev (Crimea, Soviet Union, 50" reflector) detected in Aristarchus Fraunhofer lines in UV spectra that were much narrower than in the solar spectrum. This indicated luminescent glow which overlapped contour(?) lines. Greatest after Full Moon, but fluctuated monthly with no indication of solar activity effect. The Cameron 1978 catalog ID=621 and the weight=5. The ALPO/BAA weight=5.
On 1955 Oct 28 at UT 00:06 W. Taylor saw a naked eye flash on the Moon in the north east area, on the edge of Mare Vaporum. The flash was intense and radiated to a large area. The duration was 1/4 seconds.
On 2003 May 13 at UT06:40-07:26 W. Haas (Las Cruces, NM, USA, 12.5" reflector, x321 and x202, S=2, T=3.5) suspected (06:40-06:55UT) that he saw an oval bright feature (intensity 5.5) near the centre of the floor of Herodotus crater indenting into the shadow - however the seeing was none too good, so it is more of a suspicion than a definite sighting. At 07:14-07:26UT he re-examined the region (x202 and x321, S=1-2 and T= 3.5) and had better glimpses that conformed his initial suspicions of there being an oval indentation bright spot (now intensity 6) into the shadow in the centre of the floor. Of course Herodotus does not have a central peak! There was also a very bright spot on the NW> sunlit rim of Herodotus crater. The ALPO/BAA weight=2.
On 1965 May 12 at UT 22:20 H. Miles (UK) found a possible obscuration in Bailly crater. Most of the region was as sharp as normal, but the central area was greyish and blurred. Although the observer concerned considered themselves a non-experienced observer, another BAA Lunar Section observer saw the same effect. ALPO/BAA weight=2.
S. of Aristarchus 1951 Sep 13 UTC 14:00? Observed by Osawa (Japan, 6" reflector) "Bownish-red color, blue on NW rim of A." NASA catalog weight=3 (average). NASA catalog ID #546.

Moore(?) alreted, saw no anomaly in 15 in refl. & 5-in refr. under fair conditions from 2209-2228h. Reading reported neg. fr. 2250-2345h (after phenom.). Foley reported color in it but also a crater to S. of it & Aris., prob. due to seeing conditions." NASA catalog weight=5. NASA catalog ID#1408. ALPO/BAA weight=3.
On 1995 October 6 at UT 21:30 R. Lena (Rome, Italy - a UAI observer, 11.4cm reflector) saw 4 or 5 flashes from Herodotus crater. Light intensities (mag?) ranged from 9 to 8 and they were brighter through a red filter. There is no 2006 Cameron catalog entry for this observation - it has come from the UAI web site. The ALPO/BAA weight=3.
Aristarchus-Herodotus 1971 Sep 02 UTC 20:00 Observed by Ayeau (Paris, France, 12" reflector, x100) "Brownish-red or maroon seen on Aris. W.wall ridge to Herod. on S.wall of Herodotus" NASA catalog weight=2. NASA catalog ID #1311. ALPO/BAA weight=2.

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 1985 May 02 at UT 20:20-20:38 J.D. Cook (Frimley, UK) noted at 20:20 found the south rim (and just outside) to be blurred in appearence and there was also a hazy shadow inside the crater. M.C. Cook found a "break in clarity in break on S wall". Miles (UK) also found the south wall blurred in appearance and Foley (Kent, UK) noted that the area was featureless and the 2 craters positions at 1 o'clock high up on the inner wall were obscured", although just north of these was sharp detail. Foley also recorded that the shadow on the east wall was opaque"and that thye inside of Aristarchus was slate/blue in colour and dull, however by 20:28 the crater had brightened by 0.4 steps on Foley's CED device and the missing craterlets were visible again. Jean (Canada, 4" refractor) observed a rose colour intermittently (UT 1948- 20:58) - however Cameron suspects that this is chromatic aberation. The Cameron 2006 catalog ID=269 and the weight=5. The ALPO/BAA weight=3.
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.
On 1977 May 30 at 21:04-02:13UT J.H.-Robinson noted a loss of detail inside Gassendi, however he did not regard this as a TLP. The effect was also seen by P.W. Foley. Cameron 2006 extension catalog TLP ID=16 and weight=0 ALPO/BAA weight=1.
On 1983 Dec 17 at UT 17:25-19:20 Moseley (Covington, England, UK, x120 and x240, seeing=III and spurious colour present) found that the inside of Aristarchus crater was dull and slightly blue. Suspected the colour to be spurious: at 19:20 at x240 the colour was pink but at x120 there was no colour. Cameron 2006 catalof ID=234 and weight=3. ALPO/BAA weight=2.
Amery (Reading, England) saw blue in Aristarchus but a photograph did not show the colour. Foley thinks this was spurious colour. Cameron 2006 extension catalog ID=27. ALPO/BAA weight=1.
Peter Foley observed a tiny yellow-brown region close to the tip of the cape, north east of the precipitous west edge, in the face of the north facing slope. The area concerned was diffuse and varied in density despite the surroundings not varying. Foley notcied no colour elsewhere on the Moon, though Amery thought that he saw some in Aristarchus, but Foley thinks this was spurious. Cameron 2006 catalog extension ID=27 and weight=5. ALPO/BAA weight=3.
Flashing spot at end of SV fluctuated. Herzog, Darling & Weier confirmed spot but not fluctuation. Spot brighter in red than blue, but Cobra Head was bright in blue. No other region was abnormal.
Aristarchus-Cobra Head, 1967 Nov 15 UT 05:40-06:00 Observed by Cross, Tombaugh (Las Cruces, NM, 12" reflector x800) and Harris (Tucson, AZ), and Dunlap (Organ Pass, NM, 24" reflector with Moonblink). "Obs. reddish color N. & E. of Aris. & more intense color nr. E.(IAU?) rim of Cobra Head. Red color nr.C.H. confirmed by Tombaugh. Obtained 10 photos between 0543-0549h in 3 spectral bands (blue, yellow, red, & integ. light). No change dur. obs. per. but spot got smaller at moments of good seeing. Isodensitometry of photos. At Corralitos 0152-0155 on 24- in image intensifier & filter sys. photoos at 0320-0330h. Harris at Tucson got spectra. Neither of latter 2 show anything unusual. Its edges were nebulous even at best seeing. Size @ that of Cobra's Head." NASA catalog weight=5 (very good). NASA catalog ID #1053.
