Bright spot (in dark part of Moon - confirmation of Arkhipov?). Cameron 1978 catalog weight=5 and Cameron 1978 catalog serial No. 418,
Proclus 1955 May 25 UT 19:30 Observed by Firsoff (Somerset, England, 6.5" reflector x240, seing=very good) "E. (IAU?) wall equally bright in red and green filters, dull in blue, invisible in violet. (in p.c. time given is 0730UT, but must have been 7:30PM loc. time." NASA catalog weight=4 (good). Cameron 1978 catalog ID=594 and weight=4. The ALPO/BAA weight=3.
On 1980 Nov 11 at UT17:35-18:32 G. Blair (Weir, Scotland, UK) at 17:35UT immediately noted that the Earthsine was extremeley bright. All large detail easily seen on unilluminated disk. 17:38UT a definite pale reddish brown tinge enveloped the Aristarchus area. 17:39 seemed to be getting larger and more intense west (IAU) side. Attempted to contact other observers. 17:40UT Aristarchus still had a bright central peak. 17:50UT fading a little from the west (IAU). 18:00UT slight revival in brightness. 18:15UT effect still visible when Aristarchus set behind a high western horizon. The two sketches supplied show the illuminated region around the crater with extension to the west (IAU). P. Foley (Kent) found thatAristarchus was bright enough in Earthshine to be seen with the naked eye. Telescope in operation at 18:00UT and the entire Aristarchus region was bathed in violet/rose colour with what appeared to be a strong ray extending to the west (IAU). Detail could be clearly seen inside Aristarchus crater such as the central zone, west and north wall and rim in relief from point southeat to northwest. CED measure 0.8 (white), 0.9 (blue), 0.2 (red). No other reading in Earthshine gave a measure in red. Observation ceased by 18:32UT as the Moon was very low. ALPO/BAA weight=3.
On 1970 Jul 07 at UT 23:00-23:30 Celis (Paso Hondo, Chile, 3" refractor, x60, x100, x135, seeing=good) observed the following in Aristarchus: "Similar conditions as last night (#1264) but diminished in brightness to 40% (to 6deg bright. Real phenom. in the dimming?)". The Cameron 1978 catalog ID=1265 and weight=3. The ALPO/BAA weight=3.
Om 1990 Mar 01 at UT 00:59-02:20 D. Darling (Sun Praire, WI, USA, 3" refractor, x36) observed that Aristarchus could barely be seen, but at 02:15 UT it brightened by about two times. Note that brightening might refer to Lambert - it is worded in an ambiguous way in Cameron's catalog). The Cameron 2006 catalog ID=392 and weight=0. The ALPO/BAA weight=1.
Om 1990 Mar 01 at UT 00:59-02:20 D. Fryback (Madison, WI, USA, 8" reflector) observed that Lambert was a star-like point, but later saw it brighten up (02:15UT) by two times (note that this brightening might refer to Aristarchus - it is worded in an ambiguous way in Cameron's catalog). The Cameron 2006 catalog ID=392 and weight=0. The ALPO/BAA weight=1.
In 1948 Aug 09 at UT 02:40 Woodward (Toronto, Canada, sky very clear) observed, using a telescope, a bright, bluish-white to greyish-yellow, 3 sec duration flash in Earthshine. The flash was between magnitude 0 to 1 if one were looking for a similar magnitude star in the sky without a telescope. There was possibly a very slight motion of the flash in a southerly direction. Also there were two terminal bursts. Cameron suggsts that this might have been a meteor? Ref: Moore, P.A. Guide to the Moon (1953), p117. The Cameron 1978 catalog ID=508 and weight=0. The ALPO/BAA weight=1.
On 1990 Jun 27 at UT02:17-03:00 D. Darling (Sparta, WI, USA, 3" refractor, x36) reported that the crater had "Flared up at 0225 as a point of light then went down" - the effect was fairly brief. Earthshine was quite clearly seen and all features elsewhere were normal. The Cameron 2006 catalog ID=405 and the weight=0. The ALPo/BAA weight=1.
Macrobius 1972 Apr 17 UT 20:10-20:45 Observed by Persson (Hvidore, Danmark, 2.5" refractor x58 & x100, seeing=good) "Macrob. was a white ring without outline or shadow. (shad. should have been seen--sun only up 5deg alt. Something was raising albedo from 0 to surround." NASA catalog weight=3 (average). NASA catalog ID #1328.
Proclus 1972 Apr 17 UT 20:10-20:45 Observed by Persson (Hvidore, Danmark, 2.5" refractor x58 & x100, seeing=good) "Proclus not as clear as usual" NASA catalog weight=3 (average). NASA catalog ID #1328.
On 1972 Apr 17 at UT 20:10-20:45 Hvidore (Denmark, 2.5" refractor, x58, x100, seeing=good) noted a brightening of the dark limb between Hercynian mountains and Cleostratus crater. Thought that it was due to atmospheric disturbance. Cameron says similar to other reports e.g. No. 1156. The Cameron 1978 catalog ID=1330 and weight=1. The ALPO/BAA weight=1.
In 1824 May 02 at UT 21:00-21:15 Gobel (Germany, seeing = excellent) saw near Aristarchus (47W, 23N) a soft (matte) light like a star seen through mist. Brightness increased suddenly to magnitude 9-10. After several seconds it became weak, finally disappearing. repeated this 3 to 4 times in 15 minutes. The Moon was a very narrow sickle shape and a major feature could be seen in Earthsine. The date given was 1821 but Cameron says it is 1824. The Cameron 1978 catalog ID=88 and weight=4. The ALPO/BAA weight=3.
On 1970 Jul 08 at UT 23:00-23:30 Celis (Paso Hondo, Chile, 3" refractor, x60, x100, x135, seeing=excellent) observed the following at Aristarchus: "Conditions again similar (to #1264). Brighter tonite(8 deg) than last nite. but not as bright as on the 6th. Pin pts. of light very accentuated. The radial open hand extended fingers form not so frequently, perhaps because of the larger crescent illum. now.". The Cameron 1978 catalog ID=1266 and weight=3. The ALPO/BAA weight=2.
On 1885 Feb 19 at UT 19:00-20:00, Gray of England?, saw a small crater (in it?) that was dull red with vivid contrast. The Cameron 1978 catalog ID is 247 and the weight=3. The ALPO/BAA weight=3.
Cyrillus G 1983 Aug 13 UT 20:17-20:59 L. Paynter (Radcliffe, UK, 22cm reflector, seeing III or better, transparency good). Cyrillus G was relatively bright and surrounded by a shaded area. On increasing the magnification from x65 to x130 he became aware of a diffused "carise" colouration, in and around the crater. The colouration was similar though to other spurious colour on the Moon, but unlike other areas affected by spurious colour, was more diffuse and spread out and not so concentrated. In view of some uncertainty by the observer, ALPO/BAA weight=1.
McClure vicinity 1976 Apr 04 UT 19:36-2009 Observed by McKay (England, 3" refractor, x160), Savill (England, 10x50 binoculars), Moore (Sussex, England, 15" reflector, x360, seeing II), Buss (England, 6" reflector), Brady (England, 8" reflector), Ross (England), Foley (Kent, England, 12" reflector) "Noted a fuzzy, glowing spot at 1936h at 160x. 2 min later, spot grew larger & flashed up to very bright. Changed power to 106x, & 80x, still vis. Spot faded 10 m later, then suddenly flashed up again. 5 m later it faded again & disappeared at 1959h. At 2006h returned to fuzzy, glowing spot then disappeared at 2009h, never to reappear. Some obs. confirmed, others did not. Photos afterward don't show anything, nor did blink aftwerward." Moore though nothing unusual. NASA catalog weight=5. NASA catalog ID # 1431. ALPO/BAA weight=3.
On 1965 Oct 30 at UT 0200 Eastman (Palos Verdes, CA, USA, 12" reflector) observed a brightening in Aristarchus in ashen light. The photographs that were taken show it. The phenomenon was seen each lunation since July. The Cameron 1978 catalog ID=908 and weight=5. The ALPO/BAA weight=2.
Posidonius 1821 Apr 07 UTC 18:00? Observed by Gruithuisen (Munich, Germany) "Small bright crater in it was shadowless. Schroter also saw it shadowless several X" NASA catalog weight=4 (good). NASA catalog ID #87. ALPO/BAA weight=3.
On 2009 Mar 01 at UT 18:50-21:00 G. Smith (East Yorkshire, UK, 127mm Maksutov Cassegrain telescope with zoom eyepiece and later a Plossl eyepiece) observed an area between Plato and Sinus Iridum to be glowing as a bright nebulous patch. It was brighter than anything else in Eartshine. A change in eyepiece did not affect the appearance of the nebulous patch. The patch had faded somewhat by 21:00UT. The observers brother attempted to observe the patch through a 114mm reflector at 20:30UT but the optics were of poor quality and the effect was not seen. BAA observers were alerted, but only after the event had faded - they made observations from 22:00-23:46 UT but failed to detect anything unusual in the region concerned. The ALPO/BAA weight=1. This may have been a mis-identification with Aristarchus - however we cannot be 100% sure.
In 1965 Jul 04 at UT 03:53-05:59 Gridley, Welch (West Covina, CA, USA, 4.5" and 8" reflector, seeing=excellent), Albert (CA, 8" reflector, x375) and Emanuel (8" reflector) observed star-like flashes in Aristarchus crater. Cameron says this confirmed and that the date in MBMW is 7/3/65 which is local time = 4th UT also but is in error due to misreading of handwriting. The Cameron 1978 catalog ID=883 and weight=3. The ALPO/BAA weight=3.
In 1963 Oct 22 at UT 21:00? Andre (Belgium, 2.25" refractor) noticed that Posidonius A's shadow was not seen when it should have been seen. The Cameron 1978 catalog ID=777 and weight=3. The ALPO/BAA weight=2.
In 1855 Jun 20 at UT 21:00 T.W. Webb (England) observed a trace of twilight (Cameron says also seen by Gruithuisen, Henry and others at times). Webb gives a low weight to his own observation, saying "for want of better optical means". The Cameron 1978 catalog ID=130 and weight=1. The ALPO/BAA weight=1.
On 1881 May 04 at UT 20:00? Trouvelot (Meudon, France) observed an unexplained light inside Eudoxus crater. The Cameron 1978 catalog ID=222 and the weight=3. The ALPO/BAA weight=3.
On 1965 Oct 30 at 23:30-23:50UT Fehring and Garris (Parasmus, NJ, USA, using a 2.4" refractor x88, seeing very good) saw a fuzzy area -- variations in shape and distinctness, seen in an area east of Atlas crater. A drawing was made. It was noted that no other area had a similar effect. Cameron 1978 catalog ID=909 and weight=3. ALPO/BAA weight=3.
On 2012 Mar 28 at UT 20:45-20:50 Two unknown Italian observers, reported on an on-line formum that they had independently seen a distinct glow with a comma/drop shape. One of them moved the Moon and the glow moved with the Moon. It is uncertain how experienced the observers where. A chart was provided which shows the lcoation of the glow in the western side of Mare Imbrium. It is just possible that this was Aristarchus in Earthshine, though that is very slightly further west and south than the observers reported. ALPO/BAA weight=1.
On 1994 Apr 17 at UT02:00 R. Zit (Madison, WI, USA) whilst observing a grazing lunar occultation, found that Aristarchus (and the surrounding region) was glowing in Earthshine. This was confirmed by D. Weier (Madison, WI, USA) at 02:00 UT also. The ALPO/BAA weight=1.
On 2012 Mar 28 P. Grego (Cornwall, UK, seeing II, 100mm refractor, x132) observed a patch of light just inside the NW rim of Menelaus on the shadowed wall or floor. Computer visulaiztions of the illumination conditions using a digital elevation model failed to produce this effect. ALPO/BAA weight=3.
Cepheus A 2000 Oct 04 UTC 08:15-08:50 Observer: Maurice Collins (New Zealand, 90cm ETX) - observer noted that crater was extremely bright - wasn't sure if this was normal and at the time rated it as the brightest (contrasty?) crater that he had ever seen on the Moon. Many years later he suspected that he may have mis-identified the crater. This still leaves us with thr problem as to why a crater should be so bright in this region, and if so, which one? ALPO/BAA weight=1.
Pitiscus 1981 Sep 05 UT ??:?? but assumed to be AM? which would make it 00:00-03:00UTC. Observed by Slayton (Fort Lauderdale, Florida, USA, 8" reflector, ASA 64EK7 f/170, Kodak Kodachrome) photographed a bright glow in the crater that appeared to move. Observer also reported seeing it visually noting that it looked gray with a tinge of red. For further information see p266 of Sky & Telescope (1991, March). Note that Cameron gives the date and UT at 1981 Sep 06 UT 01:00-01:30, or one day later. I will use this date and time from now on. The Cameron 2006 catalog ID=152 and weight=5. The ALPO/BAA weight=3.
In 1982 Sep 24 at 22:45-23:40 K. Marshall (Medellin, Columbia) saw in Theophilus an obscuration on the south west wall close to Cyrillus and furthermore it had a red / mauve colouration (seen best in a 12mm Ortho eyepiece). Through a Wratten 15 yellow filter the region was quite bright. At23:40UT the obscuration faded. There was plenty of detail in the region between Theophilus and Cyrils. The Cameron 2006 catalog ID= 184 and the weight=3. The ALPO/BAA weight=3.
On 1915 Apr 21 at UT 1800? Houdard (France) noticed a special occurrence south of Posidonius which he took as evidence of water vapor. The Cameron 1978 catalog ID=351 and weight=3. The ALPO/BAA weight=2.
Albategnius 1972 Jun 18 UTC 19:20-19:25 Observed by Schnuchel (13.25E, 52.5N, 20x60 binoculars?) "Bright area at the inner N wall, diminution of brightness well observable" S=4 T=4. Ref: Hilbrecht & Kuveler Moon & Planets (1984) Vol 30, pp53-61.
A.S.Williams of West Brighton, UK, using a 2.75" Acromatic refractor (x75, definition good, but it was too windy to use the 5.25") noticed that the mare was a mass of light streaks and spots. This was not considered unusual, but these features were unusually plain, distinct and brught, especially the streaks. The observer could not recall seeing the streaks so bright and clear with this instrument before, and indeed hardly ever with the larger 5.25" telescope. The observer continued to observe Mare Crisium on many nights for several months and comments that such an unusual exhibition was later seen perhaps once every 2-3 lunations. They are uncertain how much this effect depends upon the state of the Earth's atmosphere. This TLP does not make it into the Cameron 1978 catalog and so may not be a TLP - however it has been included, just in case, and to try to understand what was actually seen. ALPO/BAA weight=1.
Censorinus 1984 Jul 05 UT 21:05-21:25 Observed by Cook (24" reflector with line scan photodiode array at Mill Hill observatory, London) "Two line scan photodiode array images were taken which used the motion of the Moon to build up an image. The first image at 21:25UT did not include all of Censorinus, but the part that it did include was not very bright. The 21:25UT image did include all of Censorinus and the crater was bright, including the part that was just visible in the previous image. Possibly the seeing was worse at 21:05? and this could explain the brightness descrepency, but it is worth checking again by taking images at the same illumination conditions" BAA Lunar Section report. At 21:17 M. Cook (Frimley, UK) found Proclus to be brighter than Censorinus (more so than the previous night) and obtained variable readings for Censorinus. Cameron 2006 catalog ID=247 and weight=3. ALPO/BAA weight=2.
Proclus 1972 Jun 18 UTC 20:50-21:15 Observed by Kern (8.75E, 48.25N, 60mm refractor) "Yellow to white bright pattern at the NW wall, visible only occasionally" S=4, T=3 Ref: Hilbrecht & Kuveler Moon & Planets (1984) Vol 30, pp53-61.
Knopp of Paysandu, Uruguay on 1885 Feb 21 at 23:00-23:30? UT saw red patches in the crater. Reddish smoke or mist. The observer says several others had seen a star like point there that night. Cameron's 1978 catalog ID=348 and weight=4. ALPO/BAA weight=3.
Triesnecker Rille 1912 May 23 UT 18:00? Observed by Gordeenko (Russia) "Change in shape from representation by Brenner and Krieger not accountable by lighting conditions" NASA catalog weight=0. ALPO/BAA weight=1. NASA catalog ID #339.
SW of Pico 1844 Apr 25 UT 20:00? Observed by Schmidt (Athens, Greece, ? refractor) "A bluish glimmering patch of light not quite within the dark side" NASA catalog weight=4. NASA catalog ID #123. ALPO/BAA weight=3.
Proclus 1970 Jul 11 UT 20:35-20:45 Observed by Dean, Jamieson, Sparks (Ruislip, ------, England, 6" relector x156) "Dean saw something in Proclus, alerted Jamieson who saw nothing unusual at 2043h, but tho't Secchi was quite bright. At 2035 Sparks saw Proc. fluctuate. Red & blue filters showed some reduction in brightness. E. edge showed darkening, but not as dark as in shadows. 10 min later, returned to normal. (Sparks confirmed Dean)." NASA catalog weight=5. NASA catalog ID #1267. ALPO/BAA weight=3.
Purbach 1970 Apr 14 UT 12:00-14:00 Observed by Osawa (Awajt-Shima, Japan, 8" reflector, x288) "Photos in blue and orange taken. Ill- defined obscur. in blue photo in S. part of crater compared with orange. (neg. is so faint it is doubtful. Apollo 13 watch. Similar to Alter's findings in Alphonsus)." NASA catalog weight=2 (low). NASA catalog ID #1250.
1970 Jul 11 UT 20:35-20:45 During a TLP alert for Proclus, Jamieson saw nothing unusual, but found instead that Secchi was quite bright. NASA catalog weight=5 (very good). NASA catalog ID #1267. ALPO/BAA weight=1.
2009 Apr 13 UT 18:55-20:00 J. Adee (UK) and later A. Jarwaski (UK) saw Mons Pico to be incredibly bright. Adee reported naked eye visibility, though this does not show up in later CCD images. Jarwaski saw another nearby Mt very bright as well. This has been assigned an ALPO/BAA weight of 1, though I suspect it is just normal for Pico to get quite bright at sunrise.
Patches of brightness seen in the area between craters Aratus and Joy. Seemed to the observer to be perhaps slightly brighter than one would expect - the observer thought that their observation only barely constitured a TLP but decided to send the report in anyway. This has been assigned an ALPO/BAA weight of 1.
On 1965 Jul 08 at 01:00?UT a white streak was seen in Grimaldi, extended towards the limb. This was observed by Rubens de Azevedo, et. al., Brazil. The Cameron 1978 catalog ID=884 and weight=3. ALPO/BAA weight=2.
On 1990 May 03 at UT 02:03 D. Darling (Sun Praire, WI, USA, seeing steady) observed a point of light inside Alphonsus just to the north of the central peak, along the "center ridge". It was seen again, half way between the central peak and the noth west rim - along the ridge. All other features were normal. The Cameron 2006 catalog ID=403 and the weight=3. The ALPO/BAA weight=3.
Alphonsus 1967 Aug 13 UT 18:40-18:55 Observed by Horowitz (Haifa, Israel, 8" reflector?) "Glow or hazy patch seen while using filters. Brighter than background. Not seen after 2055 or next nite" NASA catalog weight=3 (average). NASA catalog ID #1041.
On 1972 Apr 21 at UT19:01 Mattingly (Apollo 16 commander, in orbit around the Moon, using his naked eyes) saw a bright flash from below his horizon on the lunar farside (approximate longitude=180 deg). he was dark adapted at the time. However no sesimic event was recorded and so Cameron suspects that this was not a meteor impact but a cosmic ray striking his eye. The Cameron 1978 catalog ID=1331 and weight=3. The ALPO/BAA weight=3.
Peirce A (Swift=IAU name) 1937 Mar? 23? UTC 22:00 Observed by Wilkins (England, UK, 12.5" reflector) "Obscuration on floor if crater. Crater invis. (similar to #394, 396)." NASA catalog weight=4 (high). NASA catalog ID #412. Note this is almost certainly supposed to be 1934 Dec 23!
SE of Ross D 1964 Aug 16 UT 04:18-05:20 Observed by Harris and Cross (Whittler, CA, USA, 19" reflector?) "Bright area. Condensations varying with time" NASA catalog weight=3. NASA catalog ID #840. ALPO/BAA weight=3
Piton 1961 Jan 25? UTC 00:00? Observed by Schneller (Cleveland, Ohio, USA, 8" x53) "Red obscuration concealing peak, @10mi sq (if near SR, date is 27th; ancilary data given for 27th -- date not given)" NASA catalog weight=3 (average). NASA catalog ID #731.
On 1887 Nov 23 at 16:15-17:00 UT Von Speissen & others of Berlin, Germany, using a 3.5" refractor (x180), saw a "Triangular patch of light (time in Middlehurst catalog wrong? Moonrise was at > 18:30h. If year =1887, age=8.8 days & time OK. must be same observation as ID=256 in Cameron 1978 catalog - note similarity of names and also the reference date). Cameron 1978 catalog ID=258 and weight=1.
Proclus 1984 Jul 06 UT 20:29-20:43 light green spot observed by Madej (England) in the central region. No colour seen elsewhere. At 20:10 Foley (Kent, UK, 12" reflector) had seen a small extending of darkening in the south east floor (not present 2 hours before) and a lot of fine detail - though everything was normal again by 22:50UT. At 22:15 Amery (Reading, UK) found a large dark spot on the south east floor. Other observers: J and A.cook (Frimley, England) could not confirm but their seeing was IV and tranparency was poor" Mobberley found no colour and also no detail on the floor. BAA Lunar Section Report. Cameron 2006 catalog ID=248 and weight=3. ALPO/BAA weight=3.
Alphonsus 1968 May 05 UTC 20:00 Observed by Farrant (Cambridge, England, 8" reflector, x220, Seeing: Good). "Did not see gray patch SE (ast. ?) of c.p. Noted W. (ast. ?) dark patch was invis. while S. one was seen easily, emerging from shadow. On 7th all seen easily, emerging from shadow. On 7th all 3 clearly vis. with the darkest one the invos. one on 5th." NASA catalog weight=3 (average). NASA catalog ID #1071.
Plato 1882 Mar 27 UTC 20:10-21:00 Observer: A.S. Williams (Brighton, UK, 5.5" saw the shadow filled floor of Plato at Sunrise with a "Glowing and curious milky kind of light". About 1 hour after sunrise at Plato, there was no trace of this effect. The TLP filled the whole floor except at a quarter of the diameter from the east wall which was actually quite black. The observer saw a curious phosphorescent glimmer at sunset (April11th?). Cameron comments that Birt, Nelson and Waugh saw obsecuring mist or fog in Plato on many occasions. Cameron 1978 catalog ID=229 and weight=3. ALPO/BAA weight=3.
A track of reddish light, like a beam, was seen crossing the shadowed floor of Plato.This TLP has an ID No. of 17 in Cameron's 1978 catalog and a weight of 3. It has an ALPO/BAA weight of 2.
On 1979 Sep 29 at UT10:00-12:00 S. Turner (Maryborough, Australia) observed a strong beacon like flash in white light that moved back and forth in the east wall of Plato (very bright) and Mons Pico. tried changing eyepiece and the field of view, but this wasn't the cause of the effect. A check at 11:07UT did not show the effect, but it was back again by 11:18UT being more pronounced at Mons Pico than the east wall of Plato. SSW of Mons Pico was also blinking slightly. At 11:32 the blinking effect was irregular 5-10 sec and this continued until 12:00UT. Cameron 2006 catalog ID=71 and weight=0 but she suggests atmospheric scintillation as a cause. ALPO/BAA weight=1.

It divided into 2 components & space between B-ring & globe cutting ring into 2 disjointed ends persisted till dark limb passed onto globe of Saturn, then a short red line corresponding exactly to chord of planet disk defined by lunar limb. It increased in length as occult. progressed. It suddenly vanished after 3/4 of globe had been occulted. No afterglow at spot on limb, no irreg. at limb could be seen. Obs. eliminates Saturn, telescope, & atmosp. as possible cause.

Flynn (Edinburgh, UK, 29cm reflector, Wratten 25 and 44a filters) observed that there were two whitish semi-circular tide like marks enclosing two dark patches adjoining the interior west wall The observer was puzzled because if these were two masses of spawning foot hills, then why would the cental areas, presumably the higher parts, be dark - when the contrary is usually the case? ALPO.BAA weight=1.

Abel (Leicester, UK, 20cm reflector, x312, seeing III-IV) observed that the north east wall was slightly brighter than would have been expected, slightly blurred (not seeing related blurring) and had a strong orange-brown colour. No spurious colour seen elsewhere. A change in eyepieces showed the same effect. No luck in alerting other observers. A drawing was made at 23:20UT and finished at 00:12UT. At 23:12UT part of the inner NW floor had a dull brown colour, whereas before it was grey.By 00:11UT the colour effect was fading and by 00:18 seeing condirions were too bad to continue. M. Cook (Mundesley, UK, 9cm Questar telescope, x80, x130, seeing III, transparency moderate to good) had observed Tycho earlier in the evening at 22:15UT, but had seen no signs of colour. W. Leatherbarrow (Sheffield, UK, 8cm scope, high cloud interuptions and bad seeing) had taken monochrome images at UT 20:07 and 20:10, but these showed nothing unusual, and he checked the crater visually at 00:00-00:30, but detected no colour, although the Moon's low altitude contibuted to poor seeing conditions and some spurious colour was seen. CCD images from M. Collins (Palmerston North, New Zealand) taken at 00:46UT showed nocolour apart from spurious colour on contrasty edges, in no way reflecting what was seen early by P. Abel.

Moore (10" Armagh refractor, x360) was observing too 22:10-22:40, with and without a Moon Blink but detected no redness, however his observing conditions were not very good at the time. NASA catalog ID #1039. NASA catalog weight=3. ALPO.BAA weight=2.
A.S.Williams of West Brighton, UK, using a 5.25" Calver, x150 and definition fairly good. Observer noticed that the Mare seemed covered with a close network of innumerable streaks, and spotted with countless numbers of light specks, so that it would hardly be possible to delineate them all in one night. The spots and streaks together must have numbered ~1000. The observer had never seen anything like the number of spots and streaks. Peirce A, was not at all easy to see and neighboring spots almost as bright made it difficult to distinguish which one was Peirce A. ALPO/BAA weight=3.
Plato 1966 Sep 25 UT 23:12-23:35 Observed by Moseley (Armagh, Nortern Ireland, 10" refractor, x140) "Eng. moon blink sys. blinks inside the crater. Very dubious due to low alt. of moon." NASA catalog weight=1 (very low). NASA catalog ID #982.

Faint greenish-blue streamers resembling terr. aurora streamers. He thought they were same cause on the Moon. The Cameron 1978 catalog weight=3 and ID=192.
On 1973 May 06 at Ut 04:48 Bell (Lodi, CA, USA, 8.5" reflector x142) saw a slow brightness increase in Reiner to magnitude 6, when suddenly in the north east (IAU?) quadrant of the floor there was a very bright pin-point blue-white flash of magntude 2 for approximately 0.5seconds. After this the bright glowing of the crater diminished over about 15- 20 sec befofre returning to normal. The Cameron 1978 catalog ID=1366 and weight=3. The ALPO/BAA weight=3.
Plato 1919 Mar 05 UT 17:19:17:34 Observed by Selivanov, Tartakov (Russia, 4" refractor? x150) "Crater seemed to be an intense green in the background of Ashen light. Slightly to the left (east?) of it's centre a bright spot that sparkled with a phosphor. light, lighting up the whole crater so that its W. edge could be seen. Light did not change for the whole time." NASA catalog weight=4 (good). NASA catalog ID #371.
Mare Crisium 1972 Mar 18 UT 19:06-21:00 Obsevred by Prvost and Dorchain (Belgium, 3.5" reflector, 168x and 336x) "at 1906h Pruvust rep'ted 2 pts. moving from Aout to Prom. Olivium. Minutes later, Dorchain saw a new pt. Others saw nothing unusual fr. 1912-2100h (Fitton, Ash, Peters, Watkins,et al in England - but this was later than the event)" NASA catalog weight=2 (poor). NASA catalog ID #1325.
In 1949 May 31 UT02:37 LT Johnson observed a flash near the W limb of the Moon at the same latitude as Riccioli. No colour seen, the magnitude was 9-10, and duration < 0.5 sec. If there was any motion then it must have been < 24 km. He wasn't looking at it when it happened, so the motion aspect is uncertain. Indeed he was not absolutely certain if it was on the limb, or just inside or outside? The BAA/ALPO weight=1.
On 1972 Mar 18 at UT2015 E. Watkins, P. Hooks, D. Harris and R. Pieper (Conditions bad: a lot of mist and haze in the sky, 10" (x80 and x160) and 4.5" reflectors (x45, x150 and x225), observers were located in the UK) Aristarchus seen on the night side of the Moon - P. Hooke saw a red orange outburst from the ctater. When E. Watkins had a look, it just resembled a misty white area i.e. normal. Eyepieces were changed but it stayed misty white. Hooke was an inexperienced TLP observer at the time. Watkins did however notice some variation in brightness but put this down to atmospheric conditions. This is a BAA observation. ALPO/BAA weight=1.
On 1939 Feb 23 at UT17:00 Malakhov, Filippoova (Russia) observed an intensive luminescence in background of ashen light that had ceased in March, in Aristarchus (confirmed of Andrenko - says Cameron). Cameron 1978 catalog ID=446 and weight=5. ALPO/BAA weight=3.
On 1969 May 21 at UT 03:40-04:25 Kohlenberger (Fullerton, CA, 12" reflector), Harris, Miller (Torrence, CA, 12" reflector), Bell and Calkins (Ojai, Duarts, CA, USA), Kelsey (West Covins, CA, Riverside, CA, USA) observed scintillations in Aristarchus - Cameron says independent observations?). Members of Astronet took part in this observation. Kelsey saw a brightening but not on the order of seconds as others reported. Cameron suspects an atmospheric effect and also comments that this was during the Apollo 10 watch. The Cameron 1978 catalog ID=1130 and weight=2. The ALPO/BAA weight=2.
On 1970 Jun 08/09 at UT 23:30-00:00 Celis (Quilpue, Chile, 3" refractor, x60, seeing=good?) observed lots of activity in the Aristarchus region - blue luminous star-like points, frequently appearing. Cameron comments that maybe atmospheric effects. The Cameron 1978 catalog ID=1260 and weight=1. The ALPO/BAA weight=1.
On 1881 May 04 UT 20:00 "Gamma" a psuedonym for an astronomer (Germany?) observed Aristarchus to be be a very bright 8th magnitude star with pulsations. The Cameron 1978 catalog ID=221 and the weight=3. The ALPO/BAA weight=2.
On 1969 Jul 19 at UT 03:53-04:19 Harris (Torrence, CA, USA, 12.5" reflector), Bell (Duarte, CA, USA, 4.5" reflector), and Miller (Ojai, CA, USA). "Harris saw 20 brightenings or light flashes, lasting fr, 1/2 to 3s at 03:53:56 (1/2s), 03:54:19 (1s), 03:54:55 (2s), 03:55:06, 03:56:54, 03:56:56, 03:58:37, 03:59:58, 04:07:28, 04:15:00, 04:16:02, 04:16:45, 04:20:29, 04:21:14. First 4 were confirmed by Bell, Harris also saw 100 mi(160km) long limb brightening (blue) between Aris & Grimaldi, due W. of Aris., brighter than Aris. At 04:14 saw the brightening 1/2 way between Aris. & Grim. as pinkish or orange. Miller at 0417h saw a star-like pulse in W. (IAU?) rim of Grimaldi. (confirm. of Harris'04:16:45 obs. ? Apollo 11 watch)." The Cameron 1978 catalog ID=1161a and weight=3. The ALPO/BAA weight=3.

On 1877 Jun 15 at UT 20:00 Birt (England, UK) observed a bright spot east of Picard. The reason why this was regarded as a TLP, accoridng to Cameron was that it was supposed to be faint or invisible. The Cameron 1978 catalog ID=193 and the weight=3. The ALPO/BAA weight=3.
On 1983 Sep 11 at UT 23:52 K.P. Marshall (Columbia, 12" reflector, x268, seeing II), whilst sketching the crater Janssen noticed a tenuous red patch on the southern junction of the valley which joins Fabricius to A. Nothing resembling this found on nearby areas. The ALPO/BAA weight=1.
