On 1944 Mar 12 at UT 23:00 H.P. Wilkins (Kent, UK, 8.5" reflector) observed that Plato appeared incomplete - the central crater had it's north wall obscured. cameron comments that maybe this was due to the low altitude of the Moon? The Cameron 1978 catalog ID=491 and the weight=4. The ALPO/BAA weight=2.
Alphonsus 1972 Jul 29 UT 00:30-03:30 Observed by Morgan (England, UK) "Orange spot just W. of c.p. on central ridge; circular area @ 15-25km diam, larger than c.p. Was bright orange then turned orange-brown toward center. Central 4,5km was darker than rest; bownish-black with blue-white specks flashing in center. Obscur. there but ridge clear elsewhere. The dark spot SW of c.p. could not be seentho outside of color area. Sketch. It had appearance of dome of atm. thicker at center. Never seen before in 11y. Next nite brighter. NASA catalog weight=3.

On 2002 May 30 at UT02:30-02:44 C. Brook (Plymouth, UK) suspected that Aristarchus crater looked dimmer than normal. The ALPO/BAA weight=1.
On 1964 Feb 02 at UT08:30-09:40 G.Reneau and B.Crowe (2.4" refractor, x90)observed Ross D to be double. This was during a time when observers were looking for a Ranger crash plume. The Cameron 1978 catalog ID=799 and weight=1. The ALPO/BAA weight=1.
Something resembling a cigar shaped shiny object seen on S rim - hanging over a smaller crater. It looked like a bright aluminum can in the sun & cast a shadow onto the rim. The length was 8-10 miles long x 1 mile wide at the central point. It appeared tapered to points at both ends. Observer studied it for several hours. S term. ~60-70miles away. Apparently not related to topog. Alt. 8deg. Cameron 2006 Extension catalog weight=3. ALPO/BAA catalog weight=1.
Observed by Bartlett (Baltimire, MD, USA, 5" reflector, x150) "N. half of crater hazy & ill-defined". S=5, T=4. NASA catalog weight=4 (good). NASA catalog ID 571.
Alphonsus 1972 Jul 30 UT 00:30-03:30 Observed by Morgan (UK using a reflector) "Orange glow, brighter this nite than last nite. Following nites were cloudy. Aristarchus and Gassendi were negative." NASA catalog weight=3. NASA catalog ID #1338. ALPO/BAA weight=3.
On 1979 Aug 12 at UT07:00-10:35 D. Darling and wife (Sun Prarie, WI, USA, 12.5" reflector, x342, photos, S=9/10) observed a cigar shaped protruberance in Romer crater that cast a 32km long shadow, nestled in a valley rille next to Romer. This was a confirmed observation. The effect persisted intil sunset. The top of the object and two points on the crater rim were reflecting the Sun's rays. "Top of obj. & 2 pts on crater rim reflected suns rays. It was as high as the crater rim whereas the rill wall was not. Took photos. he has studied this area and never saw such a phenom before. Photos did not show it". The Cameron 1978 catalog ID=65 and weight=5. The ALPO/BAA weight=2.
Eratosthenes 1976 Sep 14 UTC 04:24 Observed by Bartlett (Baltimore, MD, USA, 4.5" reflector, 45-300x, S=6, T=3 hazy) "Pseudo shadow F disappeared & wall here is same intensity as whole inner crater wall, = 4deg. No change in X, X3 or X2 (4 deg much brighter than normal)." NASA catalog weight=4 (good). Cameron c1978 atalog ID=1453 and weight=4. The ALPO/BAA weight=2.
Observations made with a variable polarizer (akin to a crater extinction device) to measure brighness with red and blue filters. Some variability in brightness noted. With the Kodak Wratten 25 and 38A filters there was little or no increase in contrast with the red filter, but with the blue filter there was a great increase in contrast of the brighter areas of the crater - the crater floor and patches of lighter material, especially at the north end. The remaining areas were supressed with the Blue 38A. ALPO/BAA weight=3.
Gassendi 1966 Dec 04 UTC 01:05-01:23 Observed by Whippey (Northolt? England, 6" reflector, x212) "Abrupt flash of red, setling in immediately to a pt. of red haze nr. NW (ast.?) wall. Continuous till 0123 (date given was 4-12-66 = European convention?)." NASA catalog weight=3 (average). NASA catalog ID #1000.
On 1966 Apr 12 at UT 01:05-01:23 Whippey (Northolt, England, UK, 6" reflector x212) and Corralitos Observatory (Organ Pass, NM, USA, 24" Moon Blink) observed in Gassendi: "Abrupt flash of red, settling immediately to a point of red haze near NW (IAU?) wall. Continuous till 0123h. (Not confirmed at Corralitos Obs. MB--at same time?". The Cameron 1978 catalog ID=927 and weight=3. The ALPO/BAA weight=2.
Alphonsus 1956 Oct 26 UT 12:54 Observed by Alter (Mt Wilson, CA, USA, 60" reflector, S=E) "Photog. thru UV & IR filters. Obscur. of E. 1/2 of floor evident in blue plates -- KodakII-O plate no filter. 2m later Kodak I-N. One pair of plates best he'd ever seen. Similar obscuration seen 2X on Linne (this started Kozyrev on his spectrographic program.)." NASA catalog weight=5 (very high). NASA catalog ID #653.
On 1980 Jul 05 at 03:20UT P.Moore (Selsey, UK, 12?" reflector) found Aristarchus to be "Very brilliant indeed". Cameron 2006 TLP catalog ID=100 and weight=3. ALPO/BAA weight=2.

Copernicus 1996 Sep 06 UT 01:45 Observed by C Brook (Plymouth, UK, 60mm refractor x28, x112, transparency, not good) "Shadows of central mountains could not be seen although the shadows on the crater ramparts were visible" BAA Lunar Section report. ALPO/BAA weight=2.
On 1975 Sep 29 at 21:15-21:55UT P.W. Foley (Kent, UK, using a 12" reflector, x200, seeing III), saw colour on Plato - blue on the inner south west rim and red on the inner south east rim. No colour was seen elsewhere on the Moon. This was a BAA Lunar Section Observation. ALPO/BAA weight=2.
On 1969 Feb 12 at UT 12:00 Taboada (Mexico, seeing=excellent) found that the Aristarchus region had the same characteristics as the previous days, perhaps a little darker colour brown, but more remarkable. He used red, blue and green filters and a difference in colour was noticed in and out of the region. Cameron suspects that permanent colour was being seen? The cameron 1978 catalog ID=1116 and weight=3. The ALPO/BAA weigh=2.
On 1884 Sep 16 at UT 09:30-10:00 Heywood (Westville, Ohio, 2" refractor) saw an unusually bright glow covering dark part, nearly uniform. Thought it was electric because it was too bright for Earthshine. It obscured features. The Cameron 1978 catalog ID= and weight=1. The ALPO/BAA weight=1
On 1882 Nov 07 at UT 05:00 Hopkins (UK) observed the dark eastern limb and a line of light and attributed this to a lunar atmosphere. Further details can be found in: Reference: Sirius 16, 279, 1883. Cameron 1978 catalog ID=229 and weight=3. ALPO/BAA weight=2.
On 1941 Mar 31 UT 03:15 Barcroft (Madera, CA, USA, 6" reflector) observed Aristarchus in Earthshine - Haas thought it must have been unusually bright. The Cameron 1978 catalog ID=486 and weight=3. The ALPO/BAA weight=2.
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.
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 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.
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 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.
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 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. The Cameron 2006 catalog ID=192 and weight=5. The ALPO/BAA weight=3.
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.
Plato 1886 Sep 06 UT 19:00? Observed by Valderama (Italy?) "Streak of light on dark floor of crater in shadow. (sunlight between peaks on walls?)" NASA catalog weight=0 (most unlikely to be a TLP). NASA catalog ID #251. ALPO/BAA catalog weight=1.
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.
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.
Plato 1967 Apr 18 UT 03:10-04:00 Observed by Kelsey (Riverside, CA, USA, 8" reflector x300, S=8, T-4-5). "Streak on floor showed slight enhancement in red filter comp. to blue. Later, a 2nd streak formed. Probably the sun shining thru a valley in the rim. Red enhancement permanent? (Wise suspected a blink here 6h earlier)." NASA catalog weight=3. NASA catalog ID #1027. ALPO/BAA weight=1.
In 1824 Jul 04 at UT23:00? Emmett (England, UK) observed a star-like light on the rim (in the dark). The Cameron 1978 catalog ID=100 and the weight=3. The ALPO/BAA weight=2.
Plato 1964 May 20 UT 01:00-01:30 Observed by Bartlett (Baltimore, MD, USA, 2.4" refractor x117, S=6, T=5). "Orange-red color on W. wall. Vivid" NASA catalof weight=4 (high). NASA catalog ID #813.
Alphonsus 1990 Feb 03 UT 18:00-18:23 Observed by A.C. Cook (Frimley, UK, CCD video camera, seeing III-IV). At 18:06 W and SE dark floor patches, equally dark, but at 18:10 and 18:23 the W dark patch was the darker of the two?. Between 18:06 and 18:23 and a bright patch to the north of the central peak brightned slightly wrt the its surroundings. However seeing conditions worsened as the observing session progressed, and in view of this the ALPO/BAA weight=1.
Plato 1907 Jan 22 UT 20:00 Observed by Fauth (Germany?) "Glow of light in part of crater" NASA catalog weight=3 (average). NASA catalog ID 327.
On 1952 Feb 05 at UT 05:10 J.Carle (USA, 8" reflector, x180) observed the following in Plato: "A shadow in a depression, or a cloud, or an optical illus.? Oval dark area nr. center, disappeared in 15m clear & prominenet at first then vanished. 4 of 14 spots nr. center continuously seen while remaining ones seen only momentarily. (seeing?) Drawing includes sketch on March 7. His sketch shows 18 spots, 13 same as here". The Cameron 1978 catalog ID=549 and the weight=2. The ALPO/BAA weight=2.
Alphonsus 1966 Nov 22 UT 03:17-03:40 Observed by kelsey (Riverside, CA, USA, 8" relector x300) "Seen first with (Eng.) moon blink, red filter but not in the green. Not seen at 03:42h" NASA catalog weight=4 (high). NASA catalog ID #998.
On 1969 Mar 27 at UT 18:42-18:47 Ringsdore (England, 15" reflector, x350), Moseley (Armagh, Northern Ireland) and P. Moore (Selsey, UK) observed nothing unusual in Alphonsus at 18:40UT, but at 18:45UT Ringsdore saw a blurring. At 18:43UT Mosely saw a reddush-orange patch and this was confirmed by Moore. NNW of the central peak, Mosely got a blink, but Moore did not because of too much stray light. The colour was like Jupiter's red spot, but less pronounced. The Cameron 1978 catalog ID=1118 and weight=5. The ALPO/BAA weight=4.
On 1971 Jul 31 at UT 21:40 (18:40 local time?) Miranda (Plaui, Brazil, 4" Refractor, 80x, 160x, Moon 70deg in altitude) observed an intermittent and curious brilliance on top of a peak (with irregular reflection) north of Mons Hadley (5E, 27N).

Mistiness cleared at 1930. Cleaned his eyepiece & prism but it persisted." NASA catalog weight=3 (average). NASA catalog ID #402.
Archimedes 1973 Jan 13 UTC 19:06-19:40 Observed by Theiss (51N, 9.67E, 75mm refractor) "Yellow to green colours at wall of Archimedes, became stronger until 19:09UT, constant brightness until 19:10UT and dissappeared at 19:16UT" Ref: Hilbrecht & Kuveler (1984) Moon & Planets 30, pp53-61.
Proclus 1973 Jan 13 UTC 19:30-19:35 Observed by Krojer (48.25N, 11.5E, 60mm refractor) "North East wall of Proclus extraordinarilly bright, observation interrupted by fog." Ref: Hilbrecht & Kuveler (1984) Moon & Planets 30, pp53-61.
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.
Archimedes 1971 Aug 01 UT 22:00(?) (19:00 originally given probably local time) Miranda (Plaui, Brazil, 4" refractor, x80) observed two grooves going from east to west, broadening towards the west, across Archimedes. A drawing was supplied. Apparently this was the first time that this was ever seen. Cameron suggests rays? and also says that in fact a similar phenomenon reported before in neasrly the same position (Apollo 15 watch?). The Cameron 1978 catalog ID=1303 and weight=2. The ALPO/BAA weight=1.
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.
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.
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.

Beaumont (Windermere, UK, 30cm reflector, Meade 23A and 38A filters, seeing III, transparency fairly good, some haze) observed a whitish misty effect seen bordering the shadows of the SE rim. It appeared intermittently and was not seen in the violet or red filters. Observers wonders if it could have been an effect associated with the Earth's atmosphere, which was unsteady with some haze. However, other craters appeared normal. The ALPO/BAA weight=1.
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 1977 Apr 29 at UT21:40-23:20 an unknown UK observer reported a TLP in Gassendi crater. The following are reports by observers attempting to confirm activity: J.W. Napper (Didcot, UK, 30cm reflector, x287, Wratten 25 and 44a, conditions clear 5+) received a telephone alert call at 22:00 but the sky was cloudy until 22:30. An initial look revealed nothing unusual, then at 22:54 he observed a colour blink just inside the north wall, appearing bright in red and normal in blue or white light. No loss of detail seen and the effect lasted only 2 minutes. A sketch was made. However the observer stresses that the very bad seeing casts some doubt on this observation. L. Fitton observed using a 8.5" reflector, with Moon blink device at x200, seeing was I- II. All areas negative, including Gassindi from 21:40-21:55 and again 22;00-22:25 and finally 22:50-23:30 negative. Mike Brown (Huntington, York, UK, 30cm reflector, x220 and x350, seeing 3-4/5, and transparency 5/5) - observed from 22:00-23:25UT no colour seen, nor obsecuration, all filters negative, despite seeing a lot of fine setail inside this crater.
On 1987 Oct 04 at UT 02:20 D. Darling (sun Praire, WI, USA, 12.5" reflector, x170, S=8, VG, T=5) obtained the brightest measurement he had ever recorded on the northern rim of Proclus. Brightness 9 and adjacent plain was of brightness 6.5. The Cameron 2006 catalog ID=308 and the weight=3. The ALPO/BAA weight=3.
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 1980 Jul 24 at UT02:00 F. Graham (East Pittsburgh, PA, USA, 6" reflector) took some photos (albeit out of focus) that showed a bright spot on the west rim. Cameron comments that this spot was sharp compared to the rest of the photograph, so was probably a photographic artifact. The effect was not seen in the finder scope. The Cameron 2006 catalog ID=103 and weight=2. The ALPO/BAA weight=1.
Aristarchus 1966 May 01 UT 21:55-22:45 Observed by Paterson, Brown, Sartory, Ringsdore (England, 12" reflector x252 for the former and 8.5"? reflector for the latter) "Eng. moon blink system detected red spots with vis. by all but Ringsdore. Brown saw intense white spot NW of crater wall" NASA catalog weight=5. NASA catalog ID 933. ALPO/BAA weight=4.
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 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 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 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.

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.
Alphonsus 1966 May 03 UTC 21:30 Observed by Smith (England, 10" reflector) and Corralitos Observatory (Organ Pass, NM, USA, 24" reflector, Moonblink) "Reddish patches.

On 1881 Dec 05 at UT 17:09 Johnson observed a dark lunar eclipse. Aristarchus was seen as a white spot in the coppery disk and continued so. Cameron comments that this is the normal apeparance in an eclipse? The Cameron 1978 catalog ID=226 and the weight=0. The ALPO/BAA weight=1.
On 1910 Apr 01 at UT 22:00-23:00 LeRoy (France?) during an eclipse, observed Tycho to be visible as a very bright spot standing out in the slate grey shadow. Apparently only Tycho was seen during the elipse. The mid eclipse point was at 22:14UT. The Cameron 1978 catalog ID=236 and the weight=1. The ALPO/BAA weight=2.
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?
In 1954 Jan 19 at UT 03:00 Porta (Mallorca, Baleares, Spain, 3" refractor, x50) observed the following during a total lunar eclipse: "3 brilliant yellowish-white spots between Picard & Peirce. Phosphor. light distinguished easily against gray-green background of mare. Irreg., intermittent. Did not perceive them all dur. totality. Next day had impression that all of area was less clear & lightly veiled.". The Cameron 1978 catalog ID=561 and weight=3. The ALPO/BAA weight=2.
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 1982 Jan 09 at UT 18:46-21:42 some unknown British observers saw a glow near Promontorium Fresnel during a lunar eclipse. The Cameron 2006 catalog ID=162 and weight=5. The ALPO/BAA weight=2.
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 1963 Dec 30 at UT11:00 many observers reported seeing a red glow on the North East (IAU?) limb of the Moon. This was also captured on a photograph. Cameron suggests eclipse geometry as an explanation. Thye Cameron 1978 catalog ID=792 and weight=1. The ALPO/BAA weight=1.
On 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 2000 Jan 21 UT04:40 G. Emersen (Golden, CO, USA, 30cm focal length lens with Wratten 25 ref filter) took 43 CCD images of the eclipse of the Moon and on one of them at 04:40UT (exposure 0.3 sec) a relatively bright spot appeared in the southern part of Mare Fecunditatis. The spot looks sharper than the rest of the Moon and so might be a cosmic ray? CCD images taken from Washington D.C. by A.C. Cook at this time, do not show this spot, however exposures were at intervals of 0.25 sec and so might have missed this spot if it happened during image readout. The ALPO/BAA weight=1.
On 1953 Jan 29/30 UT 23:00?, 01:00? Dubois (Floirae, France) observed excess luminescence, in Mare Fecunditatis, between 420nm and 470nm (maximum at 435nm) and between 480nm and 520nm (maximum near 505nm). 20-60% during eclipse at 50' from the centre of the umbra, during a lunar eclipse. The cameron 1978 catalog ID=557 and weight=5. The ALPO/BAA weight=4.

On 1848 at UT 21:00 Rankin and Chevallier (France?): Luminous pts. seen during an eclipse. Cameron ays that year 1847 given by Middlehurst must be wrong as age is 2.7 days for this date in 1847 and could not be 18- 19 as in Middlehurst because eclipse is on the 19th at 21h (mid) in 1948. aux. data here are for 1848. At 21:12 Forster (England) and Bruges (France) observed rapid changes in red colour. The Cameron 1978 catalog ID=126 and 127 and the weight=5. The ALPO/BAA weight=3.
On 1915 Mar 22 at UT 11:30-12:30 Jackson (France?) observed Aristarchus during a total lunar eclipse: "Dur. totality there remained vis. to the NW a red luminous pt. not much larger than Mars & of the same color". (date & time is old system and has been converted by Cameron). The Cameron 1978 catalog ID=343 and the weight=3. The ALPO/BAA weight=3.
On 1895 Mar 10 L. Swift et. al (Lowell Observatory, Flagstaff, AZ, USA) and Elger et al. (England), observed during a total lunar eclipse that Aristarchus was glowing with brilliance never seen before. This attracted everyones attantion. It extended its radiance to adjecent craters (e.g. Herodotus) all throughout totality. At the subsequent eclipse in September 1895 it was seen to be inconspicuous. the Cameron 1978 catalog ID=283 and the weight=5. The ALPO/BAA weight=4.

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.
On 1906 Feb 08 after a lunar eclipse, Frost and Stebbins determined that Linne had enlarged by 1" in size.
Aristarchus 1966 Oct 30 UTC 01:32-01:48 Observed by Bartlett (Baltimore, MD, USA, 5" reflector x79, x142, x194, S=5, T=3) "S.region of floor granulated & 6 deg bright light brownish tone; rest of crater 8deg bright white". NASA catalog weight=4 (good). NASA catalog ID #992.

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.
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.
In 1942 Feb 02 at UT 18:20-19:15 Y.W.I. Fisher (Brussels, Belgium) a whitish glow near the Earthlit limb, near to Kepler (37W, 7N). The duration of the event was 55 min. The Cameron 1978 catalog ID=488 and weight=2. The ALPO/BAA weight=1. Ref. p220-221 IAU Symposium No. 14 - The Moon.
(Baltimore, MD, USA, 5" reflector x180) "Strong violet glare on E. rim, changing to brown. At 0220 dark viol. in nimbus, at 0235 viol. changed to brown. At 0255 viol. suddenly reappeared, but faded to invis. at 0300. Again at 0308 reapp. Only time he ever saw such color changes." NASA catalog weight=4. NASA catalog ID 583. 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.
On 1982 Jul 09 at UT 01:05-01:25 P. Moore (Selsey, UK, 12.5"? reflector, seeing III) found that Aristarchus was very bright and slightly blue. Cameron comments that Moore's eyesight is not very blue sensitive. The Cameron 2006 catalog ID=175 and weight= 4. The ALPO/BAA weight=2.
On 1982 Jul 09 at UT01:05-01:25 P. Moore (Selsey, UK, 12.5" reflector, seeing=III) found that Grimaldi A was the 2nd brightest feature on the Moon, and that there was colour detected with a Moon blink device on the floor of Grimaldi. The Cameron 2006 catalog ID=175 and the weight= 4. The ALPO/BAA weight=3.
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.
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.
