Bright spot (in dark part of Moon - confirmation of Arkhipov?). Cameron 1978 catalog weight=5 and Cameron 1978 catalog serial No. 418,
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.
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.
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.
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.
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.
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.
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.
On 1969 Jul 19 at UT 16:00-18:01 Azevedo at al. (Joao Pessoa, PB, Brazil, 8" reflector) saw that the west wall of Biot was unusually bright. Had seen it without this condition several months earlier. This was from the Apollo 11 watch. Jose da Silva says that this was not a TLP as the observers were inexperienced. The Cameron 1978 catalog ID=1163 and weight=0. The ALPO/BAA weight=1.
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 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 1991 May 19 at UT 22:59 M. Cook (Frimley, UK, 12"? reflector, seeing III-IV) noted that Censorinus was a dull greyish white in colour and the apron was not diffuse. The Cameron 2006 catalog ID=426 and the 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.
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.
On 1987 Jun 04 at UT02:26-03:26 D. Darling (Sun Praire, WI, USA, S=G and T=4) observed that Mons Piton was the brightest object on the Moon that he had ever noted before. Variations seen gave the mountain a "silvery" shine. The abnormal brightness was confirmed by another independent observer. The Cameron 2006 catalog ID=302 and the weight=5. the ALPO/BAA weight=2.
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.
Mt Piton 2001 Sep 24 UTC 19:25-19:55 Observed by Marie & Jeremy Cook (Frimley, Surrey, UK) described Mt as the brightest point on the terminator flaring seen on the southern end and red in colour. Observers really thought it was normal (not a TLP) to be this bright and the flaring was spurious colour. Worth checking out just in case, and also because it looks spectacular. ALPO/BAA weight=1.
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.
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.
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.
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.
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.
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
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.
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.
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.
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.
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.
Knopp of Paysandu, Uruguay on 1885 Feb 22 at 23:00-23:30? UT saw a definite light, looking like Saturn in Cassini?. The previous night he had seen red patches in the crater. Cameron's 1978 catalog ID=348 and weight=4. ALPO/BAA weight=3.
On 1979 Dec 27 at UT 05:32 D. Louderback (South Bend, WA, USA, 6" reflector x240, seeing=3-6/10 and T=4) noticed "2 small high-sun areas nr. Eimmart - brightening around Mare Crisium, except for interior of Proclus - in blue light. They were brighter than 2 spots on Cap. Agarum rated 8.5 & Proc. 9. Not as bright next night. Probably a real blue light brightening". Cameron 2006 catalog ID=79, location on Moon: (70E, 23N) and weight=4.
Plato 1895 May 02 UT 20:45, 23:45 Observed by Brenner and Fauth (Germany?) "Streaks of light (Brenner) bright parallel bands in center Fauth (indep. confirmation?)." NASA catalog weight=5. NASA catalog ID #284. ALPO/BAA weight=1.
On 1965 Sep 03 UT03:00-05:00 D.Harris (Located near Whittier College, Whittier, CA, USA, using a 10" f/8.2 Newtonian reflector, x78 & x208, seeing 5-6, transparency 2-0) observed a ridge obscured SSW of Ross D. No drawing was made, only a written description. "Ridge not visible near crater; possible white patch 1/3 Ross D diameter" The ridge is the wrinkle ridge extending NNE from Ross D, a well established often visible feature. Harris comments that this was not one of the better TLPs seen near Ross D, and there were no independent observers, neverless he was ceratin of this being a TLP, and it was consistant with other activity seen near this crater between 1964 and 1970. Cameron 1978 catalog ID 891 and weight=3. ALPO/BAA weight=2.
Plato 1887 Nov 23 UT 20:00? Observed by de Speissens (France?) "Luminous triangle on floor. Klein says it was sunlight affect. (but similar to Klein's own obs., #190. Fort says never seen before nor since)." NASA catalog weight=0 (very unlikely). NASA catalog ID #256. ALPO/BAA weight=1.
Linne 1867 Jan 14 UT 20:00 Observed by Knott (England?) "White covering had seemingly disappeared, was a dark spot. Definition (seeing?) was poor." NASA catalog weight=1 very low. NASA catalog ID #148.
Morales of France?, observed "an illumination" in Kepler on 1884 Feb 05 at UT20:00?. The Cameron 1978 catalog ID is 241 and the weight=1. The ALPO/BAA weight=1.
Haas (Pico E) ? 1966 Sep 23 UT 19:33-20:00 Observer: Sartory (UK, 8.5" reflector) "Strong blink (Eng. sys.) on moon blink (red)." NASA catalog weight=4. NASA catalog ID #978. ALPO/BAA weight=3.

Published in Hilbrecht and Kuveler, Moon and Planets, 30 (1984) p53-61. ALPO/BAA weight=1.
On 1974 Mar 02 at UT 23:00 Fitton (Lancashire, UK, 8.5" reflector, x200, seeing = excellent and transparency = excellent) observed "A fine deep red line seen at 1st contact with B-ring of Saturn. Nothing unusual at A-ring contact. Persisted during occult. of B-ring. 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. Suggests refraction from tenuous atm. of destructive interference of reflected light from very small angle at limb, or diffraction of Saturn light grazing limb". The Cameron 1978 catalog ID=1389 and weight=1. The ALPO/BAA weight=1.
On 1960 Feb 06 at UT14:30 Morozov (Moscow, Russia) saw with the naked eye a bright point inmovable but with brightness variations in dark part of Moon, 3days past first quarter, 2days before SR! (says Cameron). Cameron 1978 catalog ID=728 and weight=3.
On 1972 Apr 22 at UT 18:58-00:28 Hopp (75mm refractor, 1200mm focal length,transparency 4 out of 5 and seeing 4 out of 5, located at 52deg 30' N and 13deg 15'E) Censorinus brighter than normal relative to Proclus. Published in Hilbrecht and Kuveler, Moon and Planets, 30 (1984) p53-61. ALPO/BAA weight=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.
Plato 1976 Nov 30 UT 19:15 T. 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.
Copernicus 1939 Mar 29 UT 19:00-19:15 Observed by Wilkins (Kent, England, 6" reflector) "C.P. diffuse light spot, faint glow s as tho in a luminous mist (3h before SR) Some indication of E.terraces, then vanished." NASA catalog weight=4. NASA catalog ID #447. ALPO/BAA weight=3.
Copernicus 1976 Nov 30 UT 19:40 T. Flynn (Edinburgh, UK, 29cm reflector, Wratten 25 and 44a filters) observed that the Copernicus craterlet chains werebetter seen through a red filter than a blue. ALPO.BAA weight=1.
Purbach 1976 Nov 30 UT 19:40 T. Flynn (Edinburgh, UK, 29cm reflector, Wratten 25 and 44a filters) observed that the crater interior was better see through a red filter than a blue. ALPO.BAA weight=1.
Clavius 1915 Apr 23 UTC 20:00 Observed by Cook (England?) "Narrow straight beam of light from crater A to B" NASA catalog weight=1 (very poor). NASA catalog ID #352. ALPO/BAA weight=1.
On 2009 May 03/10 UT23:20-00:11 P. 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. The ALPO/BAA weight=2.
Observer made a drawing over a period of 30 minutes. Upon examining drawing, and comparing with photos made under similar illumination was struck by the abnormality of a a small white blob in the north east corner of the shadowed floor. There should be no raised topography between the wall and the central peaks that could give rise to this. The making of the sketch overlapped with an earlier drawing made by Rony de Laet (Belgium) which did not show this blob. Subsequent attempts to find sketches/images at very similar illumination angles have failed to show the blob in the north east corner of the chadowed floor. ALPO/BAA weight=3.
On 1975Mar22 at UT 21:17-21:23 Findlay and Ford (Mills Observatory, Dundee, UK, 25cm refractor, Wratten 25 and 44a filters used) A white spot was observed on the rim of Bulialdus that was perhaps slightly brighter in red than in white light. The observers however decided that they did not regard this as a TLP. This is a BAA Lunar Section Observation. ALPO/BAA weight=1.
On 1997 Dec 09 at UT 18:42-19:02 P. Salimbeni(Cugliate Fabiasco, Italy, 20cm reflector) observed colour on the northern edge of the crater - 23A filter used. This is a UAI reported observation and has come from this organizations web ste. The ALPO/BAA weight=3.
On 1975 Mar 22 at UT22:10-22:25 T.Flynn (Edinburgh, UK, 30cm Newtownian, x75) observed 3 large areas on the floor of Plato to be delicately darker in the blue filter. There were of different darkness. He did not regard these as TLP, but permanent blinks. This is a BAA report. The ALPO/BAA weight=1.
On 1991 May 24 at UT 00:05-00:08 UT Romualdo Lourencon (Sao Paulo, Brazil, 60mm refractor, seeing=III) detected a circular cloud in Jansen B and H? (Gazateer report says F and K). "The crater of the event 100km diam. compared to Copernicus, dark with crescent obscured region below it. Was S of Jansen. A circular depression there was before LTP in darkness. Wonders if circ. depr. was shadow of cloud? The Cameron 2006 catalog ID= 428a and the weight=3. The ALPO/BAA weight=1.

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 se and neighboring spots almost as bright made it difficult to distinguish which one was Peirce A. ALPO/BAA weight=3.

Moore found things normal & saw Aris. brightest at 2030-2125h tho Argent & Brumder made it < Proclus" NASA catalog weight=4. NASA catlog ID #1422. ALPO/BAA weight=1.
On 1938 Mar 13 at UT 04:00-06:00 Barker (Chestnut, England, UK) noted a slight reddish colour in Plato. However Fox (Newark, UK, 6.5" reflector, x240) saw none on the south east wall, but instead saw a yellowish glow on the southern floor at the same time (confirmation?). Appearently Fox saw the same effect on Apr 10, 11, and May 8-11, then on June 8-10. The Cameron 2006 catalog ID=432 and the weight=5. The ALPO/BAA weight=3.
Proclus 1990 Mar 09 UT 00:12-00:13 Observed by Marie Cook (Frimley, UK, 3.5" Questar telescope) observed a "long plume of light" the brightness was the same as the wall region.

Event described was of two pseudo-peak/hill-like features, one on the southern floor of the crater, and another just slightly to the NW of the centre. on the southern floor of the crater. Lena suspects a combination of seeing effects and albedo markings on the floor. However this effect of two spots on the floor has not been repeated again.For further information, theory, and a sketch please see Fig 5 in this web link: http://utenti.lycos.it/gibbidomine/analisi123.htm ALPO/BAA weight=2.

Herodotus 1998 Dec 30 UT 18:50-19:10 observed by J.Knott (Liverpool, UK 22cm Newtonian, x216, seeing II, transparency good). Observer reports a bright spot, as bright as the central peak in Aristarchus on the NW rim of Herodotus at 19:10 (still there at 19:15, but the curious thing was that it was not visible earlier at 18:50? Now there is a bright craterlet here, and the observer doubted if what he had seen was unusual - though we have the rise in brightness o20 minutes to account for? The ALPO/BAA weight=1.
Two small conical mountains, near last 4th May eruption, close to the third one that he had seen before, but not these two. They were not on any map.
SE of Langrenous 1947 Aug 28 UT 21:00? Observed by Baum (Chester, England) A long mountain mass, on limb to the SE of Langrenus crater, had a decidedly bluish cast.

Proclus 1950 Jul 27 UT 02:56 Observed by Bartlett (Baltimore, MD, USA) described in the NASA catalog as: "C.p. of Proc. disappeared)" 5" reflector used at x100, NASA catalog weight=4. ALPO/BAA weight=2.
On 2002 Sep 19 at UT 06:31-07:22 R. Gray (Winnemucca, NV, USA) found that the bright areas of the crater floor, and the east facing part of the west rim, were brighter noticeably in red (Wratten 25) or white light, than in blue (Wratten 38A). The observer suspects that the apparent TLP was more to do with the relative densities of the filters and the contrast in Aristarchus than a real event. This was partly confirmed after checks on other craters, though it did not work everywhere. The ALPO/BAA weight=1.
In 1962 Dec 09 at UT 07:36 Wildey and Pohn (Mt Wilson, CA, USA, 60" reflector) observed that Oceanus Procellarum was 1.13 magnitudes brighter than normal. Observation at sunrise and is abnormal if area measured was mare. If it were an east facing wall it would be normal. The Cameron 1978 catalog weight=5. The ALPO/BAA weight=2.
Aristarchus 1963 Oct 30 UT 01:50-02:15 Observed by Greenacre and Barr (Flagstaff, AZ, USA, 24" Clark Refractor) observed 2 ruby red spots - one just to the SW of the cobra's Head and the other on a highland area east of Vallis Schroteri. A pink colour formed coverting the SW rim of Aristarchus. Effects present with or without Yellow Wratten 15 filer. Similar effects checked for elsewhere on other craters but not seen. So presumed not to have been due to chromatic aberation or astmospheric dispersion. Effecta not seen in 12" refractor, but this may have been a resolution issue. The NASA catalog ID No. is #778. The NASA catalog weight is 5 (highly reliable). ALPO/BAA weight=4.
In 1962 Dec 09 at UT 07:42 Wildey and Pohn (Mt Wilson, CA, USA, 60" reflector) observed that Aristarchus was 0.80 magnitudes (x2) fainter than average for this age (photometric measurement) Vmag=3.80, average= 3.0. The Cameron 1978 catalog weight=5. The ALPO/BAA weight=2.
On 1992 Feb 16 at UT 01:05-01:35 P. Moore (Selsey, UK, 12.5" reflector, seeing=III) found the north rim area to be both very bright and misty - though he did not think it to be a TLP but wanted it to be recorded, just in case. The Cameron 2006 catalog ID=440 and the weight=1. The ALPO/BAA weight=1.
Herodotus 1950 Jul 27 UT 03:56 Observed by Bartlett (Baltimore, MD, USA) described in the NASA catalog as: "Pseudo c.p. in Herod. Drawings. (Similar to NASA catalog event #523)" 5" reflector used at x100, NASA catalog weight=4. ALPO/BAA weight=3.

On 2002 Sep 19 at UT07:36-08:06 R. Gray (Winnemucca, NV, USA) found that Prinz was more difficlut to see through a blue Wratten 38A filter than through a red Wratten 25 filter. However he suspects that it might have something to do with the unequal (to his eyes) transmission density differences between either filter. The ALPO/BAA weight=1.
On 1975 Mar 25 at UT19:59-20:02 P.W. Foley (Wilmington, Dartford, Kent, UK, 30cm Newtownian) observed blueness along the inner southern wall of Plato. This is a BAA report. The ALPO/BAA weight=1.

No such effect was seen earlier at 23:54-23:57. Cameron 2006 catalog ID=81 and weight=3. ALPO/BAA weight=1.
On 1983 Sep 20 at UT 05:08-06:13 Louderback (South Bend, WA, USA, 3" refractor, x150, seeing poor and chromatic aberation on the limb) detected "purple"in the vicinity of Aristarchus crater and this was stongest on the north and north west external rims, however there was no "violet glare"from inside the crater. However the region of the central peak was very bright - though he could not detect the central peak. The brightness of the TLP was 4.5 and it should normally be 3 (nimbus area). Near the "big plain"it was 7. The chromatic aberation seen on the crater. There was also violet on the northen wall of Herodotus crater and the Cobra Head. Īt appeared dark blue in the blue filter", the surrounds remained gray". Apparently on the 26th the"ring was still dark with faint violet - nearly normal". Cameron comments that the TLP was due to spurious colour. The Cameron 2006 catalog ID= 229 and the weight=3. The ALPO/BAA weight=2.

Aristarchus 2015 Mar 03 UT 23:58 Brendan Shaw (UK) saw a flash on the NW rim of Aristarchus on his computer screen - the camera was working in the near IR. Seeing was not very good at the time. Unfortunately this flash occurred in between imaging sessions. No other flashes seen, despite looking. The observer considerd the possibility that it might have been a cosmic ray detection, but cannot say for sure. The ALPO/BAA TLP weight=1.
On 1983 Oct 19 at UT 21:09-23:40 G. North (Bexhill on Sea, UK, seeing III) found Aristarchus crater to be slightly blue in colour, and very bright, despite the fact that no colour was seen elsewhere on the Moon. At 22:08UT Foley (Kent, UK, 12"reflector, seeing II) obtained an extremely high CED brightness measurement and also picked up a "blue- violet" cast, especially inside the west rim, furthermore he saw noe detail in it. The Cameron 2006 catalog ID=230 and the weight=5. The ALPO/BAA weight=3.
In 1959 Nov (Day unknown) at UT 21:15-22:15 Bradford (South Shields, UK, 15" reflector, x480) observed in Plato: "Cocealed by a dusky cloud. Appeared to be stream or smoke. No change in 1h.

On 1985 Sep 28 UTC 20:54-23:52 P.W. Foley (Suffolk, UK) found (actually before 20:54 UT) brightness variance in Torricelli B. J.D. Cook (Frimley, UK) observed a brief blue coloured patch somewhere in the Torricelli B region, but could not pin it down precisely. At 22:50UT M.C. Cook (Frimley, UK, 30cm reflector, seeing III - occasionally V, transparency moderate to good) Found the crater to have an elongated appearance (in SSW-NNE direction) in white light, similar to the previous night. A bright elongated spot was seen on the NNE floor, close to where the wall should be. Not able to define the rim. There was a very dark surrounding area to the crater, similar to what it was on the previous night (roughly 1/4 brightness of Censorinus). 23:04UT brighter in yellow, then red, then blue. At 23:10 it was seen that blue filter dulled the crater - this was odd because both Censorinus and Proclus were brighter in blue, which is what he would normally expect. At23:15 UT Censorinus was brighter in blue, then yellow then red filters and some orange spurious colour seen to the south of Censorinus. At 23:23UT no spurious colour seen on Proclus or Censorinus. 23:46UT Torricelli B elongated as before, but a very faint ray might have been seen to the south west of the rim. This report is not in the 2006 Cameron catalog. The ALPO/BAA weight=3.
On 1996 Dec 24/25 at 18:12-00:02UT P. Moore (Selsey, UK, using a 15" reflector x250-360, and seeing III) saw a strong orange colour on the south wall and floor of Aristarchus. He suspected it to be spurious colour but could not detect colours on any other craters. The colour remained but at 18:12 UT he suspected a trace on colour on Mons Pico but was not sure. However he reported it to the TLP coordinator of the BAA Lunar Section. The orange in Aristarchus gradually faded and had almost vanished by 00:20UT when seeing was too bad to continue observing. At 02:30UT he was able to re-observe again and there was still a very very slight hint of orange in Aristarchus - but he comments that if he had not been looking for it he might not have noticed. ALPO/BAA weight=2.
Plato 1966 Aug 01 UT 06:14 Observed by Kelsey (Riverside, CA, USA, 8" reflector x300) The wall from the S to the NNE wouldn't focus well though at least 4 craterlets on the floor were clearly seen (Ricker uncertain if real TLP.

On 1980 Sep 24 at UT 21:13-23:50 P.Moore (Selsey, UK) at 22:45 saw loss of detail in the north west wall, especially in red light, but also slightly in blue light too. By 22:48 there was activity on the crater floor i.e. the four bright spots were visible in white light but not in red. In blue the central spot was seen and there were dark radial streaks to the south wall and south east. At 22:50 there was a loss of detail. Other craters were normal. At 23:08 the floor was dark in red, but some details were visible in blue. the effect had finished by 23:35. At21:34 J-H Robinson found Plato to be normal and no blinks, though floor clearer in red than in blue, however the floor detail had gone by 21:57. Blair suspected a dusty patch in north of Plato, especially in red light. at 21:57 and it started spreading at 21:13, then east at 21:15 and then north. Though it faded at 21:25 but was back again at 21:35, and Moon blink colour filters still gave a reaction at 21:50 - the TLP remained strong until 23:50UT.

Aristarchus 1987 June 14 UT 04:43-08:00 Observed by Curtis, Jacobs, and Manske (Yanna Research Station, Carl A. Fosmark Jr. Memorial Observatory, Madison Astronomical Society, WI, USA, 17" f4.5 Dobsonian and the 8" f10 SCT Celestron) "On the night 13/14 June 11:42 P.M. to 3:00 A.M. local time or 14 June 04:43 to 8:00 UT. Three people witnessed this event and all three of them observed with three different telescopes to rule out instrumental aberration. These three pople were members of the Madison Astronomical. The three observers involved are Keith Curtis, Tom Jacobs and Robert Manske. Keith Curtis took detailed notes of the event as he observed it. The observations were made at the Yanna Research Station, Carl A. Fosmark Jr. Memorial Observatory of the Madison Astronomical Society following the annual picnic. This is MAS dark sky site and is located near Brooklyn, Wisconsin. As they were observing the night sky they saw the Moon rising and noted a strong orange color due to atmospheric effects. Approximately 1/2 hour after the Moon rise they decided to turn one of the telescopes on it. It was at 04:43 UT, it was noted by Keith Curtis that as the Moon rose it began to loose the horizon color effect and return to its normal color, but he found that the red color was not leaving the crater Aristarchus. At first they all thought this was an atmospheric effect but decided it was a real event since they detected a second crater (Euler) showing red color on its rim. Keith Curtis said that the red color was very strong on the Western rim of Aristarchus with a strong blue/green or aqua green on the Eastern rim. Keith also reported that the glow opaque enough to prevent viewing of the interior of crater Aristarchus. He said they observed until 3:00 A.M. daylight saving time or 8:00 UT. and the red glow was still visible when they ended their observing session. Robert Manske description of the event was that he saw two craters glowing a strong red and blue giving it a rainbow effect. He said that the red glow was so strong he was unable to see the craters underneath during the entire observing session. Concerning the orientation of the red and blue was on the crater he stated that he did not remember since he failed to take any notes. Concerning whether there was any difference in appearance when they observed it with the 17" f4.5 Dobsonian and the 8" f10 SCT Celestron. He said that he could not detect any difference to the lunar formation or the color on it regardless of which telescope he used. He did mention that as the Moon was rising it had the appearance of one large Maria in the center of the disk. This illusion disappeared as the Moon rose higher into the sky. When talking to Tom Jacobs he said that he remembered that he did not see anything on the Moon until 1/2 hour after Moon rise. He said that he remembered that the entire Aristarchus region had a strong reddish or pinkish color. All three witness all reported variations in the type of color they were seeing. This would indicate that individuals color perception is a major factor during a color event. Keith Curtis saw a very strong coloration around the rim of the craters, where Robert Manske saw the entire region covered by this red and blue coloration and he could not see the interior of the craters underneath. Tom Jacobs reported that the glow covered the entire crater but he could see the crater underneath it. The Moon never achieved a height greater than 21 degrees so it could be that what the observers saw was caused by the Earths atmosphere.

Using a 15.2 cm refractor he conducted a Moon blink search with Wratten 25a and 38a blue filters. His report goes as follows: Moon Blink carried out. In Red 25 Proclus looked nearly the same as in white light. Through the Blue 38a filter, however, only the brilliant lit south east wall was clearly visible. The northeast wall was very dim with this filter. With no filters the NE and SE wall were brilliantly lit, the SE wall was almost as bright as Aristarchus. A thread like strip along the NW wall, possibly the rim of the crater, was also brilliantly illuminated. The interior of the crater was a featureless stygian black with the exception of a brilliant (intensity 9) thread of light that ran parallel to the illuminated east wall. Whether this was an L.T.P. or an optical effect of atmospheric turbulence is unknown, did not see anything similar elsewhere along the terminator though" ALPO/BAA weight=3.

On 1992 May 20 at UT 11:15 D. Weier (Sun Prairie, WI, USA, naked eye and 7x50 binouculars, sky conditions excellent) noted that Aristarchus and, an area, were very bright to the eye. In binouculars the feature was quire sharp and distinct, "> anything else on the Moon". The Cameron 2006 catalog ID=447 and the weight=2. The ALPO/bAA weight=1.
On 1979 Nov 08 at 00:16UT P.Madej (Huddersfield, UK, 6" reflector, x48 and x110, seeing II and transparency very good) detected a small faint orange spot, close to the centre, but not at the centre. Spurious colour was visible on the northern flank of Aristarchus. The Cameron 2006 catalog ID=74 and weight=3. ALPO/BAA weight=2.
Plato 1886 Nov 14 UT UT 21:45 Observed by Lihou (France?) "Brilliant band N-S, area marked G in NE was only slightly visible, poorly defined. Drawing (there were rays on the floor)." NASA catalog weight=3 (average). NASA catalog ID #253.
On 1981 Oct 26 UT 20:44-21:14 M. Mobberley (Bury St Edmunds, UK, 14" Cassegrain, seeing III) noticed an ~100deg wide fan on the floor of Theophius, radiating on the central peak upto the surrounding base of the wall next to Cyrillus crater. This fan had a hint of yellow/red. The observer did not consider this to be abnormal - there was certainly no loss of focus here as far as the observer was concerned, and no mention is made of this effect in later observations that night. Plenty of spurious colour was reported. The ALPO/BAA weight=1.
In 1937 Apr 29 at UT 09:30 Firsoff (Glastonbury, UK, 6" reflector and filters) observed a slight greenish colour (Cameron says colour of ground? no TLP?). The Cameron 1978 catalog ID=420 and Weight=4. The ALPO/BAA weight=3.
Aristarchus 1966 Aug 05 UT 05:22-05:38 Observed by Bartlett (Baltimore, MD, USA, 4" reflector x93, x125, x281, S=4, T=5), "S. part of floor was granulated & est. at 6 deg bright; faint yellow-brownish tint. Rest of crater 8 deg bright white."NASA catalog weight=4 (high). NASA catalog ID 963.
Plato 1877 Jul 29 UTC 02:00?-02:30 Observed by Gray (England?) "S. of crater a bright streak that disappeared at 0230" NASA catalog weight=3 (average). NASA catalog ID #196.

Aristarchus 1978 Nov 19 UT 22:40-23:05 Observed by Pedler (UK, 12.5" reflector, x200, seeing fair) Blue colour seen and could not focus on this part, where as other craters were nice and sharp in this filter. Aristarchus darker in red light. all other craters were normal in red. Attempts to change the eyepiece did not make any difference to the blue colour. Cameron 2005 catalog ID=43 and weight=4. ALPO/BAA weight=3.
Gassendi 1971 Jun 13 UT 07:22-08:05 Observed by Raimundo Nonato da Silva (Parnaiba, Brazil, 9.5" reflector, x180) "At 0755h variation on W.(IAU?) edge of crater "brightness seemed to become a little darker" as it was gugacious (foggy?), Was not sure it was a LTP. Other features & it were normal from 0658- 0755h". NASA catalog weight=1. NASA catalog ID 1295. ALPO/BAA weight=1.
On 1989 Apr 26 at UT 10:22-10:44 D. Darling (Sun Praire, WI, USA, 3" refractor, x36-x140) found that the eastern half of Plato crater was dark - and he checked this using several eyepieces. moderate magnification resolved the dark region into bands, but too high a magnification (x140) made the bands dissappear. The Cameron 2006 catalog ID=362 and the weight=0. The ALPO/BAA weight=1.
On 1982 Oct 08 at UT 04:15-04:30 W. Cameron (Silverspring, MD, USA, 3.5" reflector, x160, Seeing-very good) suspected blue tinge on north west rim and brown/red on south east rim of Aristarchus crater + focus was slightly difficult. No similar colour effect seen on other craters. Cameron 2006 catalog ID=186 and weight=1. ALPO/BAA weight=1.
On 1982 Oct 08 at UT 04:15-04:30 W. Cameron (Silverspring, MD, USA, 3.5" reflector, x160) found that Clavius had a "D" shaped crater on its outskirts that made it appear to have a ridge crossing through it. Cameron 2006 catalog ID=186 and weight=1. ALPO/BAA weight=1.
Triensecker Rille 1915 Jul 03 UTC 00:00? Observed by Markov (Russia) "Several spots changed their shapes compared with Gordeenko's depiction on 5/23/12 see #339; which cannot be explained by light variations." NASA catalog weight=3. NASA catalog ID #356.
On 1981 Oct 18 UT 22:14022:16 M.Mobberley (Bury St Edmunds, UK, 14" Cassegrain, seeing variable, transparency misty) found that the central craterlet on the floor of Plato was not visible, despite it being visible under similar colongitudes on other nights. Might be due to observing conditions, but observer suspicous. At 02:08 the observer comments that the central craterlet was ellusive, and at 02:42, though it is uncertain whether they regarded it as suspicous still at this stage? ALPO/BAA weight=1.
On 1891 Sep 23 at UT 22:00 Pickering, based at Arequipa, Peru, and using a 12" reflector, saw in Schroter's Valley and the vicinity "Varitions in vapor column. Drawings. Time estimated from given colongitude)." Cameron 1978 catalog ID=272 and weight=1. ALPO/BAA weight=1.
On 1982 Aug 11 at UT03:30-04:15 Mobberley (Suffolk, UK) obtained a photograph and made a sketch that revealed a needle-like shadow from the west wall to near by the central craterlet - the latter was quite clearly visible. What were not visible were the other four craterlets. The Cameron 2006 catalog ID=183 and weight=4. The ALPO/BAA weight=2.
Tycho 1983Aug30 UT 00:15-00:18 R. Moseley (Coventry, UK, 6" f/10 reflector, x60, transparency very good, seeing III, improving with altitude) attention initially caught by the impression of a rosy colouration along the NW crest and outer wall. For perhaps 2-3 min this persisted - before fading entirely. The observer felt that the cause may have been psysiological - or short-lived spurious colour. However interestingly nearby craters did not show the effect. A sketch was made over a longer time span 00:15-00:40UT. ALPO/BAA weight=1.
On 1981 Sep 20 at UT 08:00-09:40 D. Darling (Sun Praire, WI, USA, 12.5" reflector, x342, seeing=excellent) detected the small crater on its western rim But not on the eastern floor. This was odd because both are equal in size, furthermore smaller craters could be seen and the Moon was at a high altitude above the horizon, so seeing not a problem. Cameron 2006 catalog ID=154 and weight=3. ALPO/BAA weight=1.
In 1919 Feb 21 at UT 22:00? an unknown English observer observed in Lexell crater an intensely dark line going out from it. The Cameron 1978 catalog ID=370 and weight=1. The ALPO/BAA weight=1.
Aristarchus 1978 Oct 23 UT 06:30-06:34 V.A. Sage (Bristol, UK, 10.25" reflector, x250, Wratten 44a and 25, seeing II) noted that Aristarchus was surrounded by a dark area in the blue filter. They did not regard this as a TLP at the time. However because Aristarchus is surrounded by blue material in real life, this should have been brighter? For this reason, despite the observer regarding this as a negative TLP, an ALPO/BAA weight=1 has been applied.
"Observed early morning Moon, with 60mm OG x120, from 02-20 to 02-45 hrs UT targeting Plato, Aristarchus, and Alphonsus. From 02-20 to 02-30 hrs UT. Aristachus showed a faint pink colouration, where the light material contacted the darker Mare surface. This was not seen after 02- 30 hrs UT." Transparency very good, seeing somewhat unsteady at first, improving later on. The ALPO/BAA weight=2.
On 1981 Dec 19 at UT 01:00-05:00 E.V. Arsyukhin (Moscow, Russia, 3" reflector) observed that Plato was consdierably brighter than Aristarchus by several times. The image quality was very clear. The Cameron 2006 catalog ID=161 and weight=3. The ALPO/BAA weight=2.
On 1891 Sep 25 at UT 20:00 Pickering, based at Arequipa, Peru, and using a 12" reflector, saw in Schroter's Valley and the vicinity "Varitions in vapor column. Time estimated from given colongitude)." Cameron 1978 catalog ID=273 and weight=1. ALPO/BAA weight=1.
On 1977 Nov 03 at 22:13UT P.W. Foley (Kent, UK, 11" reflector, x285)saw some flickering in Gassendi (Clouds on limb - according to Csmeron?). The Cameron 1978 catalog ID=18 and weight=1. The ALPO/BAA weight=1.
Aristarchus and Cobra Head 1968 Jul 18 UT 00:50-01:30 Observed by Moseley & Corvan (Armagh, N.Ireland, 10" refractor, x255) and by Moore (Selsey, England, 3" refractor, x 120) "Distinct red glow & obscur. 1st at 0050 S. of C.H. & same size. At 0052h saw color on S.wall of Aris. Both persisted till 0100h then both (faded, then brightened, then faded. Plato, Gassendi & Kepler checked with neg. results. Obscured areas reached greatest extent at 0125h wgen it was 1/2 size of C.H. & SSE (ast. ?) of it. Moore was alerted to it & saw it in blink, but not vis. at 0107-0220". NASA catalog weight=5. NASA catalog ID 1085. ALPO/BAA weight=4.
On 1971 Jun 16 at UT 07:08-07:09 Raimundo Nonato da Silva (Parnaiba, PI, Brazil, 9.5" reflector, x90, seeing=good) observed during a lunar eclipse that the Straight Wall surroundings were darker than an observation from two days earlier. At 07:09UT tonality became clearer. As dawn was in progress and atmospheric turbulence, not sure if it was a TLP? Other features were normal. The Cameron 1978 catalog ID=1297 and weight=1. The ALPO/BAA weight=1.
Closest parts of the Moon at Saturn appearing from occultation were dull and hazy. Was this an effect of the lunar atmosphere or a high haze and halo around the Moon? Cameron's 2006 catalog extension gives this an ID No. of 3 and a weight of 1. The ALPO/BAA catalog weight is also 1.
Aristarchus 1973 May 27 UTC 01:09-01:56 Observed by Theiss (51N, 9.67E, 75mm reflector) "3 diameters of Aristarchus around its center: orange bright area from 01:09-01:56" Ref: Hilbrecht & Kuveler, Moon & Planets Vol 30 (1984) p53-61"
In 1919 Dec 19 at UT 04:00 Scholes (Huddersfield, England? USA) observed near Littrow a conspicuous ink-black mark (North of Cape Argaeus or S of Kittrow, The Cameron 1978 catalog ID=374 and the weight=1. The ALPO/BAA weight=1.
Reiner 1986 Jun 04 UT 09:15-09:33 Observed by Darling (Sun Praire, WI, USA, 12.5" Newtonian x79, x40, x35, Seeing 6, sky clear and steady - Moon 9deg above horizon). David Darling was out on the morning of 4 June observing the planet Mars. While studying Mars the crescent Moon rose giving me a splendid view of the earthshine portion of the disk. As the Moon rose higher into the sky he decided to turn the telescope onto it to the earthshine region of the Moon. He made it a practice to examine this region of the Moon to monitor for craters that appear to glow under this light. While observing he became aware of a black spot located in the sunlit portion of the Moon about 60 miles west of the sunset terminator. At first he thought the black spot was a shadow being cast by a large mountain or crater. When looking at his lunar charts he could not locate any feature that would account for it. As he continued to study the black spot he realized that it appeared darker than any shadows on the Moon. It was at 4 June 1986 4:15 A.M. CDT or 9:15 U.T. when he first sighted the phenomena and it was at 4:25 A.M. CDT or 9:25 U.T. that he realized he was seeing a lunar transient phenomena event. It was at this time that he could start to see silvery filaments or streaks in the black patch. Between 9:23 and 9:25 U.T. he watched the black patch disappear. When the black spot had disappeared he found that the location of the black spot was over the crater Reiner. he estimated that during the L.T.P. event that area covered by the black cloud was approximately 40 to 50 square miles. He also had examined other formations on the Moon during this event and none were exhibiting the same phenomena witnessed over the crater Reiner.
Southern cusp obseved by H.Hill (UK) on 1984 Jul 25. Solar Selenographic colongitude=232.6. Observer noted a dusky ill- defined strip in Earthshine extending beyond the southern cusp that appeared "atmospheric". Note that this is almost certianly not a TLP but is worth checking out if the libration and solar colongitude is similar, just to verify that this is what the Moon normally looks like. ALPO/BAA weight=1.
In 1955 Apr 24 at UT 19:20 F.C. Wykes (England?) observed a white flash north of Mare Serenitatis, near Posidonius (25E, 32N). Cameron comments that this might be a meteor in the dark. The cameron 1978 catalog ID= 588 and weight=0. The ALPO/BAA weight=1.
On 1822 Jun 22 at UT 21:20 Ruppell (Germany?) observed a "lunar volcano" in Aristarchus. The Cameron 1978 catalog ID=96 and the weight= 1. The ALPO/BAA weight=1.
