South Pole 1997 Apr 10 UTC 20:45 Observed by Livesey (Scotland, 65x33, Seeing Antioniadi II, Transparency : Thick Haze Alto Stratus, windy) "Two bright spots seen - one on southern tip of crescent and 2nd way over on the dark side of the S. limb. Earthshine seen, but no features". Probably these are just peaks making it into sunlight - though one of them was of considerable distance from the tip of the cresecent (was this the peak of eternal light?). So therefore the ALPO/BAA weight=1 i.e. it is worth checking out - however we may not be able to tell for sure until the libration matches up too.
On 1988 Feb 20 at UT22:25-22:34 H. Rodriguez Moreira (Fortaleza, Brazil, 4" refractor) observed a rapid rise in brightness at 22:25UT in Promintorium Olivium. About 4 minutes after this the brighness fluctuated 3 times and the TLP faded in 9 minutes after it started, returning everything to normal. "Bluish light point on darkside of it" - apparently a Greek observer (Aguirre) observed a flash but no date was given. The Cameron 2006 catalog ID=317 and the weight=3. The ALPO/BAA weight=3.
On 1821 Feb 06 at UT 18:00-19:00 At 18:00UT H. Kater (London, UK), Olbers (Bremen, Germany), Browne (UK), commented that Aristarchus looked like a 6-7th magnitude lumninous star, some 3-4' in diameter. At 19:00UT Aristarchus looked like a cloudy spot according to Ward and Bailley (England, large telescope, x80). The Cameron 1978 catalog ID= 84-85 and the weight=5. The ALPO/BAA weight=3.
Schroter observed Aristarchus to be extraordinarily bright on the dark side of the Moon. Cameron 1978 catalog ID=30 and weight=4. ALPO/BAA catalog weight=2.
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.
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 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.
On 1931 Feb 22 at UT 20:30 Joulia (Castelnaudary, Aude, France?) observed in the Aristarchus region: "Reddish-yellow glimmer of light, very variable with nearly complete extinction. (similar to Herschel's 1787 & Tempel's 6/10/1866 obs.)". The Cameron 1978 atalog ID=399 and weight=3.
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.

(blurred & dark) starting between Plinius & Menelaus moving towards Posidonius. Normal after 2 min. A little crater (white spot) periodically disappeared for several secs regularly every few min. There was haze above onlt this spot. A tiny crater SE of it was invis. till 2015h then became clear & steady. Color was reddish-brown. Drawing. (Apollo 14 watch)." NASA catalog weight=2 (low). NASA catalog ID 1293.
On 1972 Dec 11 at UT22:28 Cernan, on board Apollo 17, saw a flash on the east rille in Mare Orientale (88W, 20S) as he orbited the Moon. The Cameron 1978 catalog weight=1354 and the weight=3. ALPO/BAA weight=2.
2018 Jun 19 UT 04:00 G. Cross, using a 60" f/16 Cass, Strehl > 0.9, under descent seeing conditions, found that the ghost crater was not visible - was this an obscuration or just normal apeparance? ALPO/BAA weight=1.
Censorinus 1959 Sep 08 UT 22:45-23:50 Observed by Jean Nicolini (Brazil) "Much brighter than Proclus" NASA catalog weight=2. NASA catalog ID #721. ALPO/BAA weight=2.
Messier 1981 Feb 10 UT 19:20-20:10 TLP discoevered by Hedley Robinson (Devon, England) "Messier was brighter than Aristarchus in both red and blue filters and also appeared indistinct, later becoming invisible - lost in a bright streak. In comparison Aristarchus was clear. Another observer, Amery confirmed that Aristarchus was sharp in appearance but Messier certainly was not. Cook likewiese found Messier not to be as sharp as Messier A dueto a big shadow in Messier A. Pedler found that the sun facing wall of Messier was OK but that the shadow was changing from black to grey periodically at intervals of 2-3 minutes to a few seconds. By contrast he found that Messier A remained quite well defined. He tried red and blue filters but found no blink effect. At 20:23UT Pedler found that the shadow had stabilized to a shade of "mid grey" although remaining ill-defined. North also found that Messier A was distinct but Messier itself was ill-defined. Moore found the same thing but thinks that this is normal for Messier under this illumination to appear indistinct. More also saw the grey interior shadow. Price saw similar appearance to Moore and suspected that this was normal for this stage in illumination. Ratcliffe suspected everything normal - just commenting that Messier was smaller and no detail in comparison to Messier A. Madej and Taylor provided a sketch that showed again a grey interior and merging with the east wall/mare. Foley found Messier's pale grey interior to be un- focusable but in comparison Messier A was sharp. He says that he would expect a grey interior and the east wall to merge with the mare. However the complete loss of deatil and variability were not normal. Cameron comments that the Kuiper atlas confirms the fuzzy indistinct appearance of Messier and that a Lunar Orbiter picture shows a grey shadow. The Cameron extended catalog weight=5. The ALPO/BAA weight=2.
On 25 Jun 1993 at UT 23:30-23:52 Carlos Colesanti (Mairinque, Brazil) obtained two CCD images of Julius Caesar crater and noticed a brilliant fuzzy area on the rim of the crater.

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.
Limb North? 1881 Jul 04 UT 00:30 Observed by Several observers (Lebanon, CT, USA, naked eye, alt @ 10 deg) "2 pyramidal protruberances on upper limb (dark?). Points were darker than rest of moon's face then slowly faded away (atm ? moon very low)" NASA catalog weight=? NASA catalog ID #223.
On 1888 Jul 16 at UT 05:35? Holden, at Lick observatory, CA, USA saw a "Lunar Volcano, 1st magnitude star on the dark side. Yellow light tinged with red from refractor's secondary spectrum (facet glint? or peak catching sun before others? Hunt saw similar phenomenon in 1863." Corliss states that it was later revealed to be a mountain ridge near the southern termination of the Alpes. Cameron 1978 catalog ID=357 and weight=1. ALPO/BAA weight=1.
On 1889 Jun 06 at 22:00 UT Lade of France (8" refractor) saw two extremely bright spots (Plato B & D). Cameron 1978 catalog ID=262 and weight=2. ALPO/BAA weight=1.
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 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 1993 Jun 27 at UT 19:55-20:21 and 20:24-21:04) D. Kane (England? UK, 4" refractor) discovered that the central peak of Alphonsus crater was very bright. The central peak was also brighter in red than in blue light. However G. North (Herstmonceux, UK, 6" reflector, x135, seeing V-III) and M. Cook (Frimley, UK, 4" reflcrctor, x10, seeing=III) observed that the central peak was normal, however they did not use filters. The Cameron 2006 catalog ID= and weight=3. The ALPO/BAA weight=2.

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.

The Cameron 2006 catalog ID=345 and the weight=3. The ALPO/BAA weight=3.
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.

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.
On 1882 May 27 ay UT 20:00 an unknown observer (10" reflector) saw a bright luminous ray near west (astronomical?) wall on floor of Plato. Cameron suggests sunlight between peaks?. The Cameron 1978 catalog ID= 233 and weight=0. The ALPO/BAA weight=1.
Ross D 1966 Nov 23 UT 04:50-05:02 Observed by Cross (Whittier, CA, USA, 19" reflector, x250 & 2390, S=4-5 (sometimes 6), T=4, excellent contrast) Activity level 5, eastern third of Ross D's circumference possibly partly obscured. ALPO/BAA weight=1.
On 1987 Oct 03 at UT 01:0?0-02:00 R. Manske (Brooklyn, WI, USA, 8" reflector, x226) observed sunlight glinting of the walls in spectacular display of colours. White (even gold) was seen at the centre, and blue on the top most part of the rim. The white (or gold) band was thin in comparison to other bands. The observer suspects that this effect was terrestrial atmosphere related. Cameron 2006 catalog ID=307 and weight= 0. 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.

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.

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.)."

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 1980 Jul 24 at UT02:00 F. Graham (East Pittsburgh, PA, USA, 6" reflector) took some photos (albeit out of focus) that showed a bright spot on the west rim. Cameron comments that this spot was sharp compared to the rest of the photograph, so was probably a photographic artifact. The effect was not seen in the finder scope. The Cameron 2006 catalog ID=103 and weight=2. The ALPO/BAA weight=1.
Aristarchus 1966 May 01 UT 21:55-22:45 Observed by Paterson, Brown, Sartory, Ringsdore (England, 12" reflector x252 for the former and 8.5"? reflector for the latter) "Eng. moon blink system detected red spots with vis. by all but Ringsdore.

At 02:00 he observed pink on the south west wall of Aristarchus crater. At 01:24UT the Aristarchus ray was yellowish, however the entire Moon had a grey-yellow tinge of colour. Chromatic aberation was observed at 01:56UT. By comparison Gassendi was checked and had no colour. At 02:10 the crater wall of Aristarchus was unusual and was quite different in appearance to rims of other craters. The cameron 2006 catalog ID=375 and the weight=1. The ALPO/BAA weight=1.
Aristarchus 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.

Moon 1967 Apr 22 UT 02:30 Observed by Dunlap et al. (Corralitos Observatory, Organ Pass, NM, USA, 24" reflector) "UV excess as in # 1029. Gradient was 10# at term. to 25-30$ at subsolar pt. (153 deg long)." NASA catalog weight=5 (very high). NASA catalog ID #1031.
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.
On 1982 Dec 27 at UT 23:00 M. Price (Camberley, Surrey, UK, Seeing=III and transparency=good) observed that Piazzi-Smyth was brighter than Mon Piton at 23:00. Photographic atlas was checked to verify that this was abnormal. The Cameron 2006 catalog ID=193 and weight=4. The ALPO/BAA weight=2.
On 2004 May 02 at UT03:24 M. and L. van Son (Bremerton, WA, May 1st 7:24PM PST) saw a naked eye flash on the Moon. The observers were glancing up at the Moon in daylight when they saw a bright white flash (observer and his wife together) in the upper/mid Mare Serenitatis region, west of the crater Posidonius. "Larger than how Venus appears". "It was a quick flash like white, intense lightning. I'm not sure how to report degrees of arc but if the face we see is 900, and we start from the east then the flash occurred about 225 arc seconds to the west. This was observed by the naked eye, with clear skies between us and the moon." The observers checked for signs of aircraft vapour trails but could not see any. There is a possibility that it could have been sun glint from an Iridium satellite, but this needs to be checked out and usually these last longer than the observed effect. It would be useful to obtain whole Moon images under the same illunination and libration so that we can judge this observation properly. The ALPO/BAA weight=4.
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.

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.
Eratothenes 1954 Jul 14 UT 04:18-05:00 Observed by Bartlett (Baltimore, MD, USA, 5" reflector, x150, S=4, T=3) "Violet glare on E. wall bright spot (EWBS)" NASA catalog weight=4 (high). NASA catalog ID #565. ALPO /BAA catalog weight=3.

eclipse an unconfirmed impact flash on the Moon. The ALPO/BAA weight=3.
Moving glows seen around the middle of the disk during a lunar eclipse. It is possible that the TLP referred to might have been from the 1783 Mar 18 eclipse instead?
On 1978 Sep 16 at UT 18:28-18:57 G.Searle (Concord, Sydney, NSW, Australia, 8" reflector, x100, x160, S=III) observed a bright star-like point on the western (IAU) edge of Mare Tranquilitatis (x100) that appeared unlike any other crater and a check of the location revealed no suitably bright crater in that region (from a map?). Changed to a higher power (x160) and it was still there, but not as conspicuous. Observer thinks that this may have been due to the Moon's low altitiude (16 deg) and the seeing. At 18:35 he compared it to the brilliant crater Proclus and found the star-like point to be 75% of the brightness of Proclus. Ken Wallace (Australia) had been taking photos and observed the object at 17:37.5UT. The object gradually faded over the next 15 minutes and by 18:52UT could only be seen in averted vision at x100.

On 1964 May 26 UT 04:10-04:35 Bartlett (Baltimore, MD, USA, S=5, T=5). observed that Aristarchus had a strong blue-violet glow on the east wall and EWBS, with a strong violet tinge on the nimbus. Crater was hazy, could not focus it in red, green or blue light. The Cameron 1978 catalog ID= and weight=4. The ALPO/BAA weight=2.
On 1982 Jan 09 at UT18:46-21:42 P. Moore, (Selsey, UK) and others found that Aristarchus and Plato changed in brightness and colour during a lunar eclipse. Aristarchus was especially bright during the lunar eclipse. Cameron 2006 catalog ID=162 and weight=5. ALPO/BAA weight=3.
On 1982 Jan 09 at UT 18:46-21:42 P. Moore (Selsey, UK) and other observers noted Censorinus was exceptionally bright. Cameron 2006 catalog ID=162 and weight=5. ALPO/BAA weight=2.
On 1982 Jan 09 at UT18:46-21:42 Henderson, Sykes and Radley saw an obscuration near Le Verrier - a completely circular halo with dark mare showing through it for a duration of 15 minutes. This was during a total eclipse of the Moon. Cameron 2006 catalog ID=162 and weight=5. ALPO/BAA weight=3.
On 1982 Jan 09 at UT21:37 P. Moore (Selsey, UK) observed that Plato underwent brightness and colour changes, during a total lunar eclipse. At 20:07UT Madej observed a "slight anomaly in Plato". Cameron 2006 catalog ID=162 and weight=5. ALPO/BAA weight=3.
On 1982 Jan 09 at UT 18:46-21:42 M.Mobberley (UK) observed that Schmidt was very bright compared to its surroundings during a total lunar eclipse. Cameron 2006 catalog ID=162 and weight=5. ALPO/BAA weight=2.
On 1982 Jan 09 at UT18:46-21:42 Bouron (UK?) observed that the west limb, during a total lunar eclipse, had dark orange on it. Cameron 2006 catalog ID=162 and weight=5. ALPO/BAA weight=1.
On 1984 Dec 07 at UT 19:30-23:30 M. Mobberley (St Edmunds, UK, seeing=IV-V, transparency=good, spurious colour seen) found 2 bright pathces on the east rim on alternate sides of a bright region. The band from the central 16km wide region was dark on the east side. Foley (Kent, UK, 12"reflector, seeing=II-III) found Aristarchus to be not as bright as normal, apart from the band that Mobberley found (1 hour later). The dark regions were a murky green colour (bright through green, blue and yellow filters and dark through red and orange filters). Cook (Frimley, UK, transparency=excellent, CCD camera used) found a bright "bulge"on the eastern side. Apparently data suggests that the band was brighter in red than in near IR light. Cook's calibrated brightness measurements suggest that there was no change in brightness over the crater with time. Two other bright points were seen: one at the Cobra's Head and another half way between the east rim of Aristarchus and passes Herodotus. Wratten 29 (deep red), Wratten 87 (near IR) and combined Wratten 29 and Wratten 87 were used. In the red Wratten 29 filter the brightness falls at22:20 at Shroters valley and then rises in the bright ray. They return to normal at 22:30UT. There was however a lot of measurement noise from the brightness readings of points B and D. The Cameron 2006 catalog ID=256 and the weight=5. The ALPO/BAA weight=3.
On 1963 Dec 30 at UT11:00 many observers reported seeing a red glow on the North East (IAU?) limb of the Moon. This was also captured on a photograph. Cameron suggests eclipse geometry as an explanation. Thye Cameron 1978 catalog ID=792 and weight=1. The ALPO/BAA weight=1.
In 1954 Jul 16 at UT 01:12 Chernov (Russia, 2" refractor, x33) observed the following for Aristarchus: "Activity noted in it * in extension of Moon's shadow on sky for 12 min during .17phase of ecl.(source gave date as June 16, but ecl was July 16)". The Cameron 1978 catalog ID=566 and weight=1. The ALPO/BAA weight=1.
Bright light seen during eclipse. Date given as 8th but the Full Moon was on 6th according to Goldatine's "New & Full Moon's"). ALPO/BAA catalog weight=1. Cameron catalog weight=3. Cameron Catalog ID: 4. Julian date 1096 Aug 06. Gregorian date 1096 Aug 12.
On 1905 Aug 15 at UT 03:30 Rey (Marseilles, France) observed Tycho during a lunar eclipse to be visible, indeed it was described as brilliant during the eclipse (mid eclipse 03:31UT). The Cameron 1978 catalog ID=322 and weight=1. The ALPO/BAA weight=1.
Kepler 1967 Oct 19 UTC 05:00 Observed by Classen (Pulnitz Obs. East Germany, 8" reflector) and Corralitos Observatory (Organ Pass, NM, USA, 24" reflector + moonblink) "It was 1 mag brighter than aristarchus when normally Aris. is 0.3mag. brighter than Kep. Corralitos MB did not confirm." NASA catalog weight=4 (good). NASA catalogue ID #1052.
Plato 1967 Nov 17 UTC 18:36-18:50 Observed by Moore, Moseley (Armagh, Northern Ireland, 10" refractor x260) "Faint blink under SW wall. Nothing seen vis. Gone by 1839h. Reappeared at 1841, then gone by 1850h. Checks till 0200h were neg. Obs. dubious of reality of phen." NASA catalog weight=2. NASA catalog ID #1054. 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.
In 1954 Jul 17 at UT06:50-07:15 Bartlett (Baltimore, MD, USA, S= 5, T=5-1) observed near Aristarchus: "Pale violet tint on surface NE of crater, no color elsewhere". The Cameron 1978 catalog ID=568 and weight=4. The ALPO/BAA weight=1.
