On 1972 Dec 10 at UT21:11 Schmitt, whilst orbiting the Moon on Apollo 17 saw a flash in Grimaldi. When questioned by Cameron upon return to Earth, he said that he was dark adapted at the time and was unable to say whether it was a cosmic ray or an impact flash. Cameron says that there have been many similar reports in the past from Earth-based observers e.g. TLP report No. 1167). The Cameron 1978 catalog ID=1352 and weight=3. The ALPO/BAA weight=2.
On 1984 Jan 08 at UT16:30-18:40 P. Moore (Selsey, UK, seeing=III) could not see Aristarchus in Earthsine, despite, Tycho and the mare regions being plainly visible. Foley (Kent, UK) found Aristarchus to be a "soft blue patch" and North (seeing IV-V) found the crater to be one of the brightest features on the Moon. The Cameron 2006 catalog ID=237 and the weight=0. The ALPO/BAA weight=1.
On 1990 Aug 26 at UT 02:30-03:30 W. Cameron (Sedona, AZ, USA, 8" reflector, x110 and x220) observed that Proclus and Piccolomini craters both had a pink colour inside them. At a higher magnification of x220 Piccolomini was still pink and it was stronger on the central peak's wesern side. The cameron 2006 catalog ID=407 and the weight=3. The ALPO/BAA weight=1 as the Moon was not above the horizon at the date and UT given.
On 1990 Aug 26 at UT 02:30-03:30 W. Cameron (Sedona, AZ, USA, 8" reflector, x110, x220, seeing=good) observed that the north wall of Proclus crater was the brightest part of the crater, indeed very bright. Proclus and Picolomini had pink colours inside them. CED brightness measurements were as follows: "Proc. at 100x 4.0, 4.0; at 200x 3.4, 3.4; Theop. 3.5, 3.9; 3.5; Herc. 2.5, 2.75; 3.5; Atlas 2.8, 2.5, 3.0; Posidonius 3.0." The Cameron 2006 catalog ID=407 and the weight=3. The BAA/ALPO weight=1 as the Moon was not above the horizon at the UT given.
On 1990 Aug 26 at UT 02:30-03:30 W. Cameron (Sedona, AZ, USA, 8" reflector, x110 and x220, seeing=good) observed that the west wall of Theophilus crater was red (on terminator). However Posidonius was also on the terminator and no colour was seen elsewhere along the terminator, however Proclus and Piccolomini had pink interiors. At a higher power of x220 a prismatic effect was seen on the terminator in Theophilus and opther craters - "even on W rim of a crater due W of Theoph.". CED measurements of Theophilus... 3.5, 3.9, 3.5. The Cameron 2006 catalog ID=407 and the weight=3. The ALPO/BAA weight=1 because the Moon was below the horizon at this time.
1977 Apr 23 UT19:30-22:45 Foley (10.75" Newtonian and 4.5" refractor, seeing II, transpaency excellent) saw som every large variations in the brightness of Aristarchus whereas other features in Earthshine remained stable. Aristarchus was seen to be blue/violet. ALPO/BAA weight=2.
On 2012 May 26 UT21:21 J. Moeller (Syracuse, NY, USA, using a Konica Minolta DIMAGE Z5 digital camera, f/7.1, 1/250 sec exposure, ISO-50, 69mm focal length, digital zoom x3) captured a hand held image of the Moon in daylight. On the SW limb of the dark side of the Moon a bright spot can be seen. This has a brightness comparable to that of Mare Serenitatis. There is also a fainter dark blurred marking further inside the dark side. ALPO/BAA weight=1.

Agrippa 1966 Nov 19/20 UTC 23:58-00:14 Observed by Bartlett (Baltimore, MD, USA, 5" reflector x283, S=4, T=5) "Faint bluish tinge seen at base of NW wall beneath landslip" NASA catalog weight=4 (high). NASA catalog ID #995.
Cassini E 2002 Dec 11 UT 16:30-18:46 Observed by Knott (Liverpool, England, 216mm Newtonian, x216, red and blue filters used) seeing III, transparency good) "Observations carried out of the area extending from the Alpine Valley to the Crater Cassini. At 17:12 a pin point bright flash was seen NW of the rim of the crater E in white light. A 2nd pin point flash was also seen at 18:18, this time thru a blue filter. The 2nd flash was also seen on the NW rim of the crater E. The observer does not think this was a TLP as the seeing was III, but the flash was so bright as to be startling. Other peaks within the Alps were bright but were much less so in red and ble filters, where the rim of the crater E. NW edge was very bright in all filters, including white light. Incoming cloud prevented further observation." BAA Lunar Section report.
On 1997 Apr 14 at UT 20:00-22:00 F. Paolo (Legnano, Italy) photographed a lunar flare on the lunar limb.

On 1982 Dec 22 at UT 19:20-20:10 J-H Robinson (Teighmouth, Devon, UK, 10" reflector, x150, seeing=IV-V) could not distinguish between Messier and Messier A. The tail of these features was very bright - two telescopes were used. Moore (Selsey, UK, 12" reflector, seeing=III) could see Messier A but found Messier itself obscured - just see the west wall and thought that the comet like tail was unusual as it did not appear divided.

On 2003 Apr 10 at 00:40UT a GLR observer G. Jasmin (Quebec, Canada, using a 10" F-10 Schmidt Cassegrain) took a photograph of Alphonsus crater on Kodak 400ASA film with an exposure of 1/30th sec. There was a light visible (diameter 10 km) inside Alphonsus and the effect was present for 5 minutes. The observer commented that they have seen a light in this crater many times before, but never as long as 5 minutes. This report was submitted to the GLR group in Italy. The ALPO/BAA weight=2.

On 2009 Aug 28 at UTC 17:00:15-17:00:42 S. Khachatryan (Yerevan, Armenia, 127mm Maksutov-Cassegrain, x171, seeing 9 (1=worst and 10- best), Transparency 5-6 on a scale of 1 to 6) observed in the Chacornac area a series of fiery sparks (dot like with tiny rays), slightly elongated with the multitudinal rays orientated towards the south west direction. The colour was mostly red, with some yellow. The final flash was the most clear. The TLP was tiny in area, but "was distinctly bright against any other object on the Moon". The positional uncertainty of the location of the spark effect was approximately +/- 150 km, based upon an examination of an atlas afterwards. Just prior to the spark effect, something dark, small and fuzzy (only just discrnable to the eye, through the eyepiece) was seen to pass from the west across the Moon in a slight curve, round the surface of the Moon to the east (post observation estimate: seen for 3.5 sec and covered roughly 8% of the lunar diameter in that time). The area of the dark object was comparable in size to (or slightly less than?) craters such as Autolycus F (diameter 3km) or le Monnier E (diameter 4km) i.e. on the limits of vision of the scope used. The location of the flash was not exactly at the same location as the dark object passed across, but gave the impression of starting from it? A back of the envelope calculation of the lunar diameter covered in the time quoted gives an approximate speed (at the lunar distance) of 80km/s or on the very high end of typical meteor streams that pass by. At closer distances, and recalculated velocities, it is unlikely to be a satellite in low Earth orbit (20m/sec at 100km distance), but could perhaps be a bird or insect at a few km range? So was this dark object something in our atmosphere by chance passing across the field of view close to the time of the TLP flare or was at the lunar distance and related to the TLP? Incidentally, no attempt was made during this observation to move the scope to check that the TLP remained stationary against the Moon. The ALPO/BAA weight=2.
On 1988 Feb 25 at UT20:00? P.W. Foley (Kent, UK, 12" reflector) found that Aristarchus was very bright (especially in the UV end of the spectrum) despite other features not being seen in Earthshine. The cameron 2006 catalog ID=318 and the weight=1. The ALPO/BAA weight=1.

On 1995 Sep 03 at UT19:40-20:15 P. Moore (Selsey, UK, 15" reflector at x400) observed that the floor of Plato was much darker than he would normally expect and futhermore no interior craterlets were seen. there was however a white patch that was barely visible at the location of the central craterlet should have been. G. North (UK) attempted to observe nut the Moon was too low and seeing terrible. F. Doherty reported Plato normal. Cameron 2006 catalog ID=475 and weight=3. ALPO/BAA weight=1.

Oberver checking out repeat illumination condition appearence for Tycho concerning LTP #468 in the 1978 Cameron catalog. Did not see the effect from the original TLP report, but did see, immediately at looking at Tycho a very faint hint of redness in a pencil thin arc (< 1/4 circumference of the rim) confined to the top of the rim of the well-lit north east wall. Coloured arc similar in thickness to Rupes Recta, but not as sharply defined. The outer (E) edge was perhaps sharper than the inner edge. The redness was more on the inside of the top of the rim. The outside of the rim was bright white. This effect was seen in three different eyepieces, at 311x, 224x and 400x. Checked for the effect on other craters nearby but could not see this effect anywhere else. The colour had dissapeared by 01:02UT. The fade took about 1-2 minutes. Observation of Tycho continued until 01:06UT, but all seemed normal. Quick checks were made again on Tycho periodically until 02:50UT but the colour was not seen again. ALPO/BAA weight=3.
Plato 1949 Mar 09 UT 02:00-03:00 E.J.Reese (6" reflector x240) and one hour later T.R.Hake (5" refractor x300) both unable to see any detail on the floor of Plato, despite both being able to see a "difficult to see" cleft near to the crater Connon. Reese was able to see detail under similar illumination back in 1948 and 1947 and saw the floor craterlets in Plato clearly then. ALPO/BAA weight=1.
On 1989 Feb 15 at UT 03:15-03:30 M. Dixon (Palenque Ruins, Mexico, 7x35 binouculars) observed a point of light that was very bright in or near Mare Humorum. It was visible for 5 minutes then vanished. The Cameron 2006 catalog ID=353 and weight=1. The ALPO/BAA weight=1.

On 1990 Aug 30 at UT02:11-02:36 D. Darling (Sun Praire, WI, USA, 3" refractor, x90, seeing conditions: "at,. boiling") noted a coloured area on the west wall of Copernicus that was unusual in appearance - however other craters along the terminator had a similar effect. There was also a "dazzling bright spot on the E. rim and he witnessed 6 flashes from the lighted part of Copernicus over a very short time interval. Cameron comments that the colour may well have been dur to chromatic aberation because a refractor was used. The Cameron 2006 catalog ID=408 and the weight=0. The ALPO/BAA weight=1.
On 1990 Aug 30 at UT 02:11-02:36 D. Darling (Sun Praire, WI, USA, 3" reflector, x90, atmosphereic conditions: boiling) found "N rim of Proc. bright interior uniform gray". The Cameron 2006 catalog report is slight unclear as the description for thnis 1990 Aug 30 TLP also includes Copernicus and Censorinus in the list of TLP craters. So one description which might refere to Copernicus, could possibly have been meant for Proclus, namely: "Dazling bright spot on E rim. Rotated eyepiece but no change. N rim of Proc.......". The Cameron 2006 catalog ID=408 and weight=0. The ALPO/BAA weight=1.

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.
H. Davies (Llamandel, Swansea, UK, using a 3" refractor, detected a short duration reddish hue along the inner NE-NW? rim (4-7 O'Clock location. Sketch supplied to Foley (BAA coordinator).

On 1980 Jul 22 at UT20:08-21:50 G.North (Sussex, UK, 8" reflector, x144 and x207, seeing III-V and transparency fair) suspected an obscuration on the north and north west wall. The effect came and went. May have been due to seeing and image contrast? Cameron 2006 catalog ID=101 and weight=1. ALPO/BAA weight=1.
Observed by G.H. Johnstone of Albuquerque, NM, USA on 1954 Nov 05 UT 20:00 (according to Cameron), but 02:00-04:00 according to the original observation and at colongitudes 34.7 to 35.7 deg. 4" reflector, x150 used. The obsewrver reported that the western part (about 1/3rd of the interior) was pitch black with shadow. However there was a zone about as wide, or perhaps only a fourth of the total width that was distinctly a lighter bluish shade, almost like twilight. The shadows of the peaks on the western edge of the rim were clearly seen crossing this bluish shadowed area. Then this area ended sharply, and the farside was bathed in light from the rising sun. The shadows of the peak were sharply defined across the twilight zone, and the edge of the pitch black shadow was easily defined but not as sharp as the darker shadows crossing the the blue twilight zone. The observer checked other craters but did not see this condition in any of them - they all had the abrupt division between black and white that we would normally expect to see. Cameron 1978 catalog ID=579 and weight=2. Reference 1962 edition of ALPO's Journal: The Stolling Astronomer. ALPO/BAA weight=3.
P. Moore at 21:10 found the southern wall (and ontothe southern floor) of the crater to be indistinct. Elsewhere in the crater everything was sharp. The effect was still seen at 21:42UT, but less strong. A check was made for colour with aq Moonblink device, but none was seen. There was still a trace of this effect at 21:44UT, although detail was now becoming visible. By 21:48UT vertical streaks were seen crossing the floor from the obscuration area and these were more visible in the red filter and not in the blue. Cameron comments that undefined patches on the floor of Plato are not normal. By 21:55UT some craterlets on the floor started to become visible and the TLP for Moore ended by UT22:23. P.Foley was alerted by Moore and saw a "amssive dense obsecuration on the south wall, south floor and south outer glacis to the Mare". Foley noted that by 21:50UT the effect was fading and finished by 22:03UT. Foley reported an orange translucent haze covering half of the floor, but floor craterlets could be seen on and off - however his atmospheric seeing conditions were IV. At 22:00 UT Foley reported the floor close to the north wall to be "milky or misty". No detail was visible at 21:15UT and variability in the floor continued until 23:10UT. Hedly-Robinson was aleted at 21:35UT and found no difference between red and blue views of the area, however he did find that the south rim was indistinct although this effect had lessened by 22:00 UT and was normal by 22:17UT. M. Mobberly saw a white spot on the floor at 21:20 UT, whereas he normally would have expected to see craterlets. Mobberly was alerted at 21:40 UT and took some colour photos. He also made sketches that showed variability in the floor and dark lines and patches in the north west corner. However the altitude of the Moon was low. Cameron mentions that two of the photos show loss of detail at the south wall and beyond.and also a change in the floor markings.The north wall at 21:50UT was strangely reddish (didn't think this was spurious colour). The rest of the wall was sharp at 22:20UT through a yellow filter. Large bright patch in the centre and rest of the floor was apparently of the same shading as Mare Imbrium. The above notes are based upon the Cameron 2006 catalog extension TLP ID 145 and weight=4. 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.
On 1990 Jan 07 at UT 20:20-20:58 G.North (Herstmonceux, UK) thought that he detected dullness in Torricelli B crater - Cameron comments that this cannot be shadow). The Cameron 2006 catalog ID=386 and the weight=3. ALPO\/BAA weight=2.
Plato 1971 Oct 30 UT 19:35-20:55 E.Watkins (Braintree, UK, 4.5" reflector, x45,x150, x225), thought he saw a faint patch at 19:35 and it still was visible at 19:40. At 19:50-19:55 he saw what may have been the remainder. At 20:55 he noticed a shadow in the area. ALPO/BAA weight=1.

On 1990 Jan 08 at UT00:55 D. Weier (Sun Praire, WI, USA, 12.5" reflector, x159) observed an "anomalous black bar across Aris. Nearly digonal to terminator." The nearby crater Prinz had curious shadow patterns, perhaps related to the rising sun projecting shadows from the eastern rim and "reflected down"? "At 0224 W wall had a break in it & a diffuse glow where it should not be. Manske thinks it was Earthshine effect. At 0305 Weier saw Manske's bar - with diffused light and flicker like an aurora - like a gas with electric charge. At 0325 saw a strange glow in Aris. but may be due to atm. though thought it to be a LTP. Darling had never seen such effects before (flickering implies a medium in it)." The Cameron 2006 catalog ID=387 and the weight=3. The ALPO/BAA weight=3.
On 1980 Jul 23 at UT22:00 G.W. Amery (Reading, UK, 8" reflector, x144 and x207, seeing=III-V and transparency=fair) found that the interior shadow was a light grey. BAA TLP coordinator (Foley) suggests that this was light reflecting from the illuminated walls? Cameron 2006 catalog TLP ID=102 and weight=1. ALPO/BAA weight=2.
Aristarchus visible just past terminator. West wall was brighter than normal. Bright flash seen in/on NW wall - apparently in the same place as Pedler's May 17th sketch. Cameron 2006 extension catalog ID=146 and weight=4. Observed by M. Price of Camberley, Surrey, UK with a 6" reflector and a Moon Blink device. Seeing=III.
Plato 1981 Jun 13 UT 20:48-21:08 Observed by Price (Camberley, England, 152mm reflector, seeing III) Possible Moon blink (red) seen on north wall. Also the craterlets on the floor could be seen despite the observing conditions not being optimal. BAA Lunar Section observation. Cameron 2006 extension catalog ID=146 and weight=4. ALPO/BAA weight=3.
Observer noted a bright spot on the interior west wall that seemed brighter than what they would have expected. unfortunately the precise time of this observation was not recorded so the moon-rise and midnight UT values are used to place a limit on the time of observation. Images by Shaw taken at UT 1754, 18:45 and 23:13 do not exhibit the effect.
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.
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.
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.
Gassendi 1966 May 01 UT 19:30-00:21 Observed by Sartory (UK, 8.5" reflector, x500, S=G), Moore, Moseley (Northern Ireland, 12.5" reflector x350, S=E) and by Corralitos Observatory (Organ Pass, NM, USA, 24" reflector + moon blink) "Eng. moonblink & obscuration, also vis. confirm (Moore & Moseley alerted by Sartory. 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.
Blanco, J. Vidal, of Gijon, Spain (3" refractor x72) noticed an unfamiliar very bright center near to Encke. Cameron suspects that this was Encke B crater on the basis that it is a prominent small crater near to Encke. Cameron 2006 catalog extension ID=410 and weight=2. ALPO/BAA weight=1.
In 1949 Nov 03 UT 01:06 J.Bartlett (3.5" refractor, x100) noted that the floor of Herodotus was very dark, the east wall was very bright, and the floor contained a central bright peak. The BAA/ALPO weight=3.
Crick of Belgium noticed obscuration on a bright spot on the south east wall. This spot was quite prominent through a red Wratten 25 filter. The floor was very dark. Other craters were checked and were normal. A sketch was supplied and the position was the same as in other earlier reports. Cameron 2006 catalog extension ID=60 and weight=3. ALPO/BAA weight=3. 6" reflector used. Seeing=II and transparency=good.
M. Cook of Frimley, "NE ray distinct & also floor E of it, not distinct as on Dec 13 & Jan 11, while March 10, 11 & 12 seen by Price, North, Peters, Foley & M Cook, where rim was clear and sharp." - quote from the 2006 Cameron Catalog extyension - TLP ID=297 and weight=5. Cameron gives the observers confirming this TLP as: M. Cook, G. North and Davies.. ALPO/BAA weight=3.
Aristillus 1972 Dec 17 UTC 21:50-22:20 observed by Berger (51.5N, 9E, 60mm refractor, T=2, S=3) "Diffuse bright cloud in the NE corner of the crater" - Hilbrecht and Kuveler, Earth, Moon & Planets, 30 (1984), p53- 61.

Aristarchus 1919 Jun 10 UT 19:00-19:30 Observed by Lapshin (Russia) a "Greenish-yellow light shone from inside the crater for 1/2 hr. after which it returned to normal. Violet tint on W. bank & surrounding area & the dark color of the saddle & dark spot were distinct. Term. slightly E. of Herodotus. (Ast. E)=IAU W." NASA catalog weight=3. NASA catalog ID #372. ALPO/BAA weight=3.
Plato 1906 Mar 07 UT 22:00? Observed by Fauth (Germany? 6" refractor) "Color (brightness?) greatly enhanced as on the previous nite" NASA catalog weight=3 (average). NASA catalog ID #324.
On 1980 Jul 24 at UT22:10-22:55 P. Moore (Selsey, UK, 15" reflector, x360 and x400) found an area just south east of the central peak (and upto the wall) to be quite dark in blue light, but normal brightness in red light or in white light. All other features were normal colour- wise. At 22:55UT Tycho was normal again. Cameron 2006 catalog ID=103 and weight=4. ALPO/BAA weight=3.
Foley (Kent, UK) saw the west wall dull and stongly coloured. Moore (Sussex, UK) saw the wall as normal. However Cameron points out that Foley (Kent, UK) is a lot more Blue/UV sensitive than Moore. Mosely (Covington, UK) at 22:10 UT noticed a brightening on the East wall and at 01:10-01:25 UT suspected that the interior had a weak yellow-green cast to it. Cook (Frimley, UK) states that orange colour was within the interior crater, but green beyond the east rim at the 9 O'Clock and the south east corner to floor blue/mauvre beyond the northern rim NW/WSW. Foley sstates that orange and blue/mauvre might be spurious colour, but green one cannot get this way. Cameon suggests chromatic aberatons as a possibility but thinks that the observers concerned were experienced enough to recognize this if it were the cause. Cameron 2006 catalog extension ID=239 and weight=0. Moore used a 15?" refletor and Foley used a 12" refletor. Mosely experienced II seeing and good transparency. Cook had III seeing and also good transparency. P. Grego made an observation this night too. The ALPO/BAA weight=2.
Plato 1981 Jun 14 UT 21:58 Observed by Foley (Kent, England, 11.75" Newtonian, Seeing III, Transparency Good) "Obscuration Seen" BAA Lunar Section Observation. ALPO/BAA weight=2.
On 2016 Jul 17 UT 03:49 P.Zeller (ALPO, Indianapolis, IN, USA) imaged a pseudo-peak with shadow on the floor of Herodotus, however the image scale and quality of this colour image were not great and the observer suspects that it might be an imaging artefact. ALPO/BAA weight=1.
Cobra Head 1966 May 02 UT 20:05 Observed by Sartory (England, 8.5" reflector x400) "Eng. moon blink detected red spots, seen visually also". NASA catalog weight=4 (good). NASA catalog ID #934.

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.
Cobra Head 1967 Mar 23 UT 18:40-20:47 Observed by Sartory, Moore, Moseley (Farnham, England, 15" reflector (Sartory) seeing very poor & 10" refractor in Armagh, N.

Gassendi 1967 Mar 23 UTC 18:40-18:50 Observed by Sartory (Farnham, England, 15" reflector) "Heavy blink on inner S. wall. Moved toward N. at 1845, faded at 1850." NASA catalog weight=3 (average). NASA catalog ID #1019.
Aristarchus normal in red and blue filters however the Cobra Head part of Schroter's Valley was brighter in blue. Indeed it was very dull in red - Louderback says that this was not surprising as the whole areas around Aristarchus is brighter in blue. Louderback is an experienced observer of the Aristarchus area of more than 10 years. Cameron 2006 extended catalogID=63 and weight=1. ALPO/BAA weight=1.
Plato 1873 Apr 10 UTC 21:00? Observed by Schmidt (Athens, Greece, 6" refractor) "Under high sun, 2 faint clouds in E. part of 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.
Plato 1870 May 13 UT 22:00? Observed by Pratt (---), Elger (Liverpool, England), (Gledhill (Brighton, England) "Extraordinary display of lights. 27 seen by Pratt, 28 by Elger, only 4 by Gledhill. (independ. confirm. ?" NASA catalog weight=5 (very good) NASA catalog ID #168. A bit more of a detailed report is as follows: "Upon the 13th of May, 1870, there was an "extraordinary display," according to Birt: 27 lights were seen by Pratt, and 28 by Elger, but only 4 by Gledhill, in Brighton. Atmospheric conditions may have made this difference, or the lights may have run up and down a scale from 4 to 28. As to independence of sunlight, Pratt says (Rept. B.A., 1871-88), at to this display, that only the fixed, charted points so shone, and that other parts of the crater were not illuminated, as they would have been to an incidence common throughout.(30) In Pratt's opinion, and, I think, in the opinion of the other observers, these lights were volcanic."

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.
Manillus 1955 Aug 03 UTC 21:00 Observed by Firsoff (Sommerset, England, 6.5" reflector, x200) "Maniluus very bright in all colors, especially blue, extraordinarily so" NASA catalog weight=4 (good). NASA catalog ID #602.
Timocharis 1955 Aug 03 UTC 21:00 Observed by Firsoff (Sommerset, England, 6.5" reflector, x200) "Crater was bright in blue, seemed large & diffused." NASA catalog weight=4 (good). NASA catalog ID #602.
On 1978 Aug 19 at UT02:45-04:00 Porter (Naragansetts, RI, USA, using a 6" reflector, Seing = 6/10) noticed blue on the north east corner of Aristarchus and an orange glow on the south east wall. They detected no movement or change in brightness. The observer used both eyes, to make sure it was not an eye defect, and three filters: red Wratten 25, blue Wratten 82 and Violet Wratten 47. Porter found that the colours faded for a duration of 5 minutes and then returned. Their right eye gave a good view and using their left eye they suspected that it was 0.5 steps brighter than the remainder of the crater. The suspected colour remained visible, even under moments of good seeing conditions. The colour eventually faded over time and was eventually gone. Porter reportd seein gcolour here on the following night. Apparently other bright spots showed no colour. Fitton suggests that the filters used confirm that the south east wass was definitely red in colour. The Cameron 2006 catalog ID=37 and the weight=0. ALPO/BAA weight=1.
Aristarchus 1973 Nov 10 UTC 20:00? Observed by Coates (England, 8" reflector x200, Moon at gigh altitude above horizon). "Attracted to crater because of an orange hue extending towards Herod. Has seen this at other times. Thinks not a LTP, but actual color on ground."NASA catalog weight=2 (low). NASA catalog ID #1381.
Observed by Bartlett (Batimore, MD, USA, S=4, T=5) "E.wall? blue glare. He was uncertain @it. Couln't focus it. Herodotus unaffected." NASA catalog weight=4. NASA catalog ID 581. 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. Extraordinarily large & at least 9 deg bright -- like EWBS on Aris. This spot is subject to large unexplained variations. At 97 deg col. in July, Q was also 9 deg bright but very small. At col.96 deg, 5 in May '58, col.99deg in Feb.'50, & 96 deg in Nov. '55 it was not seen at all. Assoc. with tonite was a distinct blue glare on NE rim, extending for short dist. & @ 2x as far as S."

On 1992 Jul 16 at UT 03:32-09:31 D. Louderback (South Bend, WA, USA, 3" refractor, x134) detected yellow on the southern rim of Aristarchus, and the colour looked "darker" through a yellow filter and the region was "duller" than normal. The region was 1 intesnsity step brighter on the 2nd measurement, "on all points in it". The comet tail-like ray had 3 sections and was "mottled" in appearance. Finally the Cobra Head region had possible variations in brightness. The cameron 2006 catalog ID=451 and the weight=3. The ALPO/BAA weight=2.
Aristarchus 1954 Nov 12 UTC 02:20-03:05 Observed by Bartlett (Baltimore, MD, USA, S=5-6, T=3-4) "Blue-violet glare on EWBS & whole length of E. wall. Suspected viol. tint on VA; uncertain @ m" NASA catalog weight=4. This had faded later by 05:07. NASA catalog ID #582. ALPO/BAA weight=2.
On 1996 Jul 31 at 22:40UT P. Moore (Selsey, UK, 15" reflector, x300) noticed a lack of detail in the Cape Agarum area - he would normally have expected to have seen some craterlets. However he would not rate this observation much because the seeing was only III and he does not think that it was an obscuration. However just in case he wanted to record this report in the archives. ALPO/BAA weight=1.
Proclus 1973 Nov 11 UT 20:40-23:05 Observed by Savill (Cambridge, England, 12" refractor, x100?), Young (Yorks, England), Pedler (Bristol, England, 6" reflector?), Livesey (Scotland). "At 100x showed a bright spot in S.part of crater. At 300x was vis. but power too high. In 8-in refr. at 170x, at 2055h 2 spots present. Confirmed by Young. Seeing was improving. At 2104h in 12-in refr. at 260x the lower spot seemed distinctly enlarged & vaporous. Decided it was due to poor seeing. Later the 2 spots were better defined & separated but lower moved away fr. larger one & they seemed more separated than earlier. Obs. ended at 2305h when they decided it was not an LTP. but was 2 craters instead of humps. There were neg. repts. from others at the same time. (there are no craters in Proclus)." NASA catalog weight=2. NASA catalog ID # 1382. ALPO/BAA weight=1.

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 1978 May 24 at 00:40-01:05UT P. Moore (Sussex, UK, and using a 12.5" reflector at x300-400 - seeing IV) saw colour in Aristarchus (red on the south east wall and southern "horn" of the crater. He could not detect colour elsewhere, but felt that the effect might have been spurious colour. With the increasing altitude of the Moon the light effect decreased. Moore detected red the next night as well (May 25th) and on May 27th, but it was not present on May 29th. The Cameron 2006 Extension catalog ID=33 and the weight=0. The ALPO/BAA weight=1.
Four bright spots seen in Mare Crisium. There was also peculiar behaviour of the terminator. Source: Midlehurst 1968 catalog TLP ID=16. Ref Web 1962 p62-76. The ALPO/BAA weight=1.
On 1990 Jan 14 at UT 01:14-01:55 M.C. Cook (Frimley, UK, seeing=poor) observed that Aristarchus did not appear normal for this illumination. the northern half of Aristarchus was "2x>" than the southern half of the crater. There were two white patches of apron material near to the crater Herodotus that were 50% of the brightness of the southern half of Aristarchus. Furthermore the southern half of Aristarchus had a circle - "dull patch on inner S wall with a bright point shining through it. (Bartlett's EWBS?)". The Cameron 2006 catalog ID=389 and the weight=4. The ALPO/BAA weight=2.
Conspicuous bright spot seen on 6th. Also seen on 7th, absent on 8th. Cloud-like effect where light had been (on 8th). Cameron 1978 catalog TLP ID No.=139 and weight=3.

On 1961 Jul 01 at UT 00:00? an unknown Miranova (Russia or Israel) obtained some spectral photometry of lunar objects. A spectral plate in 425 -> 500nm bands. The Cameron 1978 catalog ID=743 and weight=5. The ALPO/BAA weight=3.
Plato 1938 Jul 15 UTC 06:50 Observed by Haas (12" reflector?) "Floor -- definitely green under same conditions as 5/17/38 (see #437). Kaiser after 90 obs. couldn't find any regularity to appearance of the brown color in Plato. I=3.7 comp. with I=2.0 on 6/15/38 (see #439-- color of ground?)." NASA catalog weight=4 (good). NASA catalog ID #440.
In 1955 Oct 05 at UT 03:40-03:48 Bartlett (Baltimore, MD, USA, 5" reflector, x180, S=6, T=5) observed in aristarchus an itenseley bright blue-violet glare on EWBS, E, and NE wall. The Cameron 1978 catalog IF= 620 and weight=4. The ALPO/BAA weight=2.
Near Kepler 1966 Dec 31 UT 03:00? Observed by Petrova, Pospergelis (Pulkova Observatory, Russia) "Special glow in this area. Confirmed by photoelectric method (Petrova) & polarimetric (Pospergelis?) almost simultaneously recorded by both" NASA catalog weight=5 (very high). NASA catalog ID #1007.
On 1904 Aug 01 at 05:00? Pickering (Echo Mt., CA, USA) UT Plato: "Bright hazy obj., 2" diam. on floor, Obs before & after were normal". The Cameron 1978 catalog ID=318 and the weight=4. The ALPO/BAA weight=3.
Messier A 1951 Oct 20 UT 00:00? Observed by Moore (England) "Brilliant white circular patch in it. has seen it & Messier blurred several times." NASA catalog weight=4 (good). NASA catalog ID #545 Note that the date and time given are probably wrong as the Sun is ~7deg below the local horizon at this time. ALPO/BAA weight=1 to reflect this error.
Aristarchus 1957 Oct 13 UT 07:00?$ W.Haas, according to the 1978 NASA Catalog is supposed to have seen a bright spot of light -- "explosion" in this crater. Confirmation of activity in Aristarchus - Three independent observations within 4 hours. Cameron 1978 catalog weight=5 and TLP ID No.=676. Private comunication with Haas shows that he recorded nothing unusual on the 12th or 13th. Therefore an ALPO/BAA weight of 1 has been given until this matter is cleared up.
Jansen 2013 Aug 26 UT 00:30-01:30 P. Grego (Cornwall, UK, 20cm SCT, x200, seeing II, transparency good) observed a dark patch just east of Jansen D. He had not seen this before. There maybe a depression here hinted at in LOLA ndata. ALPO/BAA weight=1.
On 2008 Oct 19 during 05:40-06:30UT D. Holt of Chipping, UK observed an anomalous patch of illumination just to the west of the centre of the Posidonius J crater. It is possible that this is just some high ground on the floor protruding through the shadow filled crater at sunset. Therefore this has been assigned a weight of 1 for now, just in case it is a TLP - until proven otherwise.
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.
Stochard of Dublin, Ireland, saw naked eye at 10:30UT on 1862 Nov 12 Aristarchus as extraordinarily bright as a bright spot on the Moon. This was seen in daylight with the waning crescent. Cameron 2006 extension catalog ID=6 and weight=3. ALPO/BAA weight=2.
On 2009 Oct 09 UT11:00-11:04 NASA's LCROSS upper centaur stage, followed 4 min later by the observation spacecraft, is due to impact into a the crater Cabeus in the hope of kicking up some dust and possible frozen volatiles. Note that this description is intended for observers on the date of impact and it is doubtful that any new science could be achieved by re-observing the same area months after the impact. If you are observing on the date of impact, then please observe around 11:00-11:04UT and ignore the predicted times in the headings. However this report is included as techniqcally if something is seen it is a TLP, albeit man-made! For those observing on the date in question here are a few observing tips to maximize the science of your observations: (1) If you are imaging, then please try to obtain images before the impact because you can then subtract these from images taken during the impact and hence show up faint changes that you might normally miss. (2) If you have a spare scope and camera,use this to observe through filters such as UBVR or I, or if you have narrow band interference filters, try observing in say Hydrogen Alpha, Methane, OH, or indeed any volatile that you might expect to see in a comet (the main source of water at the poles). (3) Please try checking the area long after the impact, just in case other effects might trigger a TLP. (4) Please go to some trouble to ensure accurate timings- these will be essential in order to understand the sequence of events - assuming any are seen. Timings can be obtained using a short wave radio or via a GPS. Note that you should always use UT or UTC. (5) Please send any observations that you make into the upload section of the LCROSS campaign observers web site. If you belong to an astronomical society e.g. BAA or ALPO, then do please send copies of your observations to the Lunar Sections of your society or club. (6) Finally this desription will be updated a day or two after the planned impact.
On 2009 Sep 09 UT23:31:43 P.Grego (St Dennis, Cornwall, UK, seeing II- III) suspected a flash south of Cabeus, just beyond the terminator. It was not bright, and lasted a fraction of a second. Thinks it might have been illusory as he saw some fainter flashes (cosmic rays?) during that nights observing session. ALPO/BAA weight=1.
On 1973 Oct 17 at Ut 11:30 Androsan (Edmonton, Canada, 6" reflector, x230) observed a glow 1-2 sec reappearance of Saturn's rings at a place of ring's appearance on the dark limb. The observers attributed it to Saturn and its rings. Cameron speculates that it might be due to gas or dust at the lunar surface. Eye was attacted to the glow which delineated the limb at a position angle of 210 deg at emersion, at Earthshine at Edmonton. The Cameron 1978 catalog ID= and weight=2. The ALPO/BAA weight=1.
On 2009 Sep 11 UT00:15-00:20 and 01:00-01:05 C.Brook (Plymouth, UK, 5" O.G., x100, seeing tremourlous but definition improving over time) noticed that the central peak(s) in Alphonsus were brightening gradually. No effect was seen earlier at UT23:30-23:35. One presumes that the effect also occured between these two observing times? The observer suspects that this was not a TLP, but is uncertain. ALPO/BAA weight=1.
On 1998 May 18 UT 02:00-03:16 C. Brook (Plymouth, UK, 60mm refractor, x112, seeing III) observed an obscuration of the central peaks of this crater. Copernicus ramparts were clearly visible. The ALPO/BAA weight=1.
UT 08:30 or UT 20:30? SW inner wall of Aristarchus was intesnity I=0.5, but was I=2.5 on July 2 at Col. 195. Observing conditions were identical. Band is darkening near col. 180. (Observation made in daylight?). Cameron 1978 NASA catalog ID=425 and weight=4 (very experienced observer). ALPO/BAA weight=3.
During sunset at this feature, with the interior in shadow the observer saw that the central peak was nebulous and fuzzy and not what one would expect. Cameron saw it on 9 Oct 1993 at sunset and noted that it was not nebulous, just a grey patch although briefly she suspected perhaps two points/peaks?. The Cameron 2006 extended catalog ID is 467 and the weight is 3. The ALPO/BAA weight is also 1. The observer used an 8" reflector and conditions were S=4 and T=4.
On 1979 Jul 18 at 08:30-10:00 D.Darling (Sun Praire, WI, USA, 12.5" reflector, x80) found that Reichenbach glowed for a short time and then faded. Cameron 2006 catalog ID=61 and weight=0. ALPO/BAA weight=1.
On 1979 Jul 18 at 08:30-10:00 D.Darling (Sun Praire, WI, USA, 12.5" reflector, x80) found that Stevinus glowed for a short time and then faded. Cameron 2006 catalog ID=61 and weight=0. ALPO/BAA weight=1.
On 1979 Jul 18 at 08:56-09:05 D.Darling (Sun Praire, WI, USA, 12.5" reflector, x80) found Cleomedes (and other features) to glow, some with flashes and pulsations. At 09:06 UT Cleomedes was glowing, but by 09:06UT it could no longer be seen. Cameron 2006 catalog ID=61 and weight=0. ALPO. BAA weight=1.
