In 1965 Jul 02 at UT 04:20-05:50 Albert and Welch (Azuss, CA, USA, 8" reflector, x375) and Emanuel (West Covina, CA, USA, 4.5" reflector) observed 4th magnitude star-like flashes to blotches in Aristarchus, in ashen light. Cameron says that this is independent confirmation and also that the date in MBMW is 7/1/65 which is local time + 2nd UT. The Cameron 1978 catalog ID=881 and weight=3. The ALPO/BAA weight=3.
In 1965 Jul 03 at UT 04:25-05:34 Emanuel (West Covina, CA, USA, 4.5" reflector) observed 4th magnitude star-like flashes and pulsations coming from Aristarchus. Cameron says this confirmed and that the date in MBMW is 7/2/65 which is local time = 3rd UT. The Cameron 1978 catalog ID=882 and weight=3. The ALPO/BAA weight=3.
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.
Plato 1944 Sep 03 UTC 03:40 - A.W. Mount (Fort Worth, TX, USA, Conditions good, seeing 6/10) saw a small white bright point of light appear suddenly close to the W. wall of Plato glowed briefly as by far the most conspicuous object in the lunar field of view and vanished quickly after approximately 2 sec. It was star-like in appearance and was stationary on the Moon's surface - about magnitude 6? Angular diameter of the flash was <= 1". Observing conditions good enough to see the central craterlet in Plato. 20cm reflector used. Ref. DJALPO Vol 45, p28 Spring 2003.
On 1963 Nov 01 at UT 00:20-00:35 Kopal and Rackham (Pic du Midi, France, 24" reflector) observed in Kepler an enhancement in red light at 672.5nm and 545.0nm. Luminescence ~86% +/-3% of background. The Cameron catalog says that Moore saw something between 23:30 and 03:00, but it is not clear what exactly, or whether it was Copernicus, Kepler, or Aristarchus? The Cameron 1978 catalog ID=779 and weight=5. The ALPO/BAA weight=5.
On 1963 Nov 02 at UT 00:00? Scarfe (Cambridge, UK) observed a spectral line dpeth anomaly? The cameron 1978 catalog ID=780 and weight=5. The ALPO/BAA weight=4.
On 1963 Nov 01/12 at UT 22:30-03:00 P. Moore (UK, 12" reflector) observed something unusual in Aristarchus/Copernicus/Kepler - the Cameron catalog is not very clear which. The Cameron 1978 catalog ID=779 and weight=5. ALPO/BAA weight=1.
On 1980 Sep 24 at UT21:34 J-J. Robinson (Teighmouth, Devon, UK, 10" reflector, x200, seeing=III) found, using a Moon Blink device, that Fracastorius blinked on the northern side in the red filter. Cameron 2006 catalog ID=110 and weight=5. ALPO/BAA weight=3.
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. The Cameron 2006 catalog ID=110 and weight=5. The ALPO/BAA weight=4.
On 1959 Nov 17 at Ut 22:00 an unnamed observer saw a light in Plato. The Cameron 1978 catalog ID=725 and weight=1. 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.
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.
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.
Alphonsus 1958 Nov 03 UT 02:30-03:30 Observed by Kozyrev, Ezerski (Pulkova Observatory, Crimea, Ukraine, 50" reflector, 23A/mm spectrograph) UT03:00-03:30 "C.p. redder than rest; emiss. spect. in 4756A, 4100, 3950A (C3), 5165, 5130A (Swann bands) 3 spect. over 3.5 h. Image of c.p. weakened in viol. light on spect. Noted visual decrease in brightness & reddish glow. Decrease in bright, & unnusual white color(at 0300h- 0330h). Sudden decrease in vis. bright.

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.
Whippey of Northolt, England, using a 6" reflector, x64 (seeing=good) saw a series of weak glows, and a final flash at UT04:18. Similar weak glows had been seen in Petavius and from this position approximating Linne (?). At 04:20UT Moseley, of Armagh, Northern Ireland, using a 10" reftactor x 80 (seeing=fair) saw a flash in the centre - Alphonsus or Parrot? Cameron says - confirmation of the last flash of Whippey? Cameron 2006 extension catalog ID=13 and weight=3. Cameron 1978 catalog ID=1042 and weight=5. ALPO/BAA weight=4.
