On 1970 Apr 13 at UT09:00-09:03 Whelan (Walters, New Zealand, using a 10" reflector) observed Menelaus to have a deep red cloud that seemed to surge upward from outside the southern edge of the crater wall and disperse around the outside edge, spreading out on reaching Mare Serentiatis. All clear again though by 09:03UT, (Apollo 13 watch). Drawing supplied. Cameron 978 catalog ID=1246 and weight=3. 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.
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.
On 1988 Jul 22 at UT 02:15-04:00 P.W. Foley (Kent, UK, 11" reflector) made a sketch of a dark area of the (East) floor of Proclus that revealed a large anomalous dark region - there should be no shade here when the sun is at an altitude of above 50 deg!. BAA lunar section archives reveal similar dark shadings - however on this night it was a different shaped dark area. The appearance was confirmed by several observers. Foley reported that the region affected stretched from Proclus to Theophilus. The TLP was seen in the USA too by D, Darling as early as 01:31UT and by others on his TLP network - brightness measurements of the "c.p." were 3.5 and the remainder of the floor was 5.5. However the observers did not all agree on the same position for this dark area. The Cameron 2006 catalog ID= 331 and the weight=2. The ALPO/BAA weight=2.

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 1983 Sep 15 at UT 05:20-05:24 Louderback (South Bend, WA, USA, 8" reflector and 3" refractor, seeing poor) found that the west wall of Eimmart was unusually bright (8.3) and apparently it was almost as bright as the "WEBS(of Aris?) at its brightest".

No craters could be seen on Plato's floor, despite observing conditions being acceptable. The floor was evenly toned, and the walls were sharply defined. By 23:10 there was a suspicion that the central craterlet was there, but he could not quite make it out, even with averted vision. ALPO/BAA weight=1.
On 1988 Jul 23 at UT03:07 D. Darling (Sun Praire, WI, USA, 12" reflector, x150, seeing = 6/10) discovered that the dark area on the floor of Proclus, seen earlier by UK observers was still present, but less so (?) and the shape changed. When viewed through a green filter it was less distinct. "Change with two other filters. Polarizer gave a circular shape with a knot on SE side & W58 in White." The measured brightness of Proclus was 9 on three sides and 8.5 on its west rim. The floor was 5.5, but the dark spot was 4. Alphonsus, Bullialdus, Copernicus, Eratosthenes, Plato and Ptolemeaus were all normal. The Cameron 2006 catalog ID=332 and the weight=1. The 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.

Could see hint of knot seen before. Craters named in 7/23/88 (#319) were all normal this time too". Is it possible that this report refers to the crater "Gray" rather than "Proclus" as the column field suggests in the Cameron catalog? The Cameron 1978 catalog ID=333 and weight=5. The ALPO/BAA catalog weight=2.
Tycho 1998 Feb 06 UT 22:48-22:54 R. Braga (Corsica (MI), Italy, 102mm f8.8 refractor, x180, with diagonal, Wratten 23A, 80A and an OR5 filter, seeing II, Transparency good).

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.
On 1994 Apr 23 at UT 03:30 the US Navy Clementine Spacecraft, in orbit around the Moon, obtained images of the Cobra Head region of Aristarchus crater that suggested a ~15x colour ratio increase (0.4 microns / 1.0 microns) in comparison with images obtained on 1994 Mar 03. This was presented as a poster paper 18.04 at AAS 31st DPS meeting. However it was later suggested that this was due to incorrect radimetric calibration procedures being followed.

Craters B & J to SE had faded, vanished at 0630. Hazy patch remained around peak, alpha low mainly to NE like a comet's tail. Slightly reddish fringe to E wall. (shown in sketch)". The above has been quoted in full from the Cmeron catalog because the catalog desription is slightly ambiguous and any attempted summary might make the description more unreliable. The cameron 2006 catalog ID=470 and the weight=3. The ALPO/BAA weight=2.
On 1992 Feb 21 at 03:00-03:55UT C. Brook (Plymouth, UK, 3" refractor x116, seeing II) found that Janssen K was very bright. Cameron 2006 catalog extension ID=441 and weight=2. ALPO/BAA weight=1.

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.

Louderback (South bend, WA, USA, 8" refletor x140) found the north wall to be very bright in red light (this is not normal as it is usually bright in blue - according to Cameron). The brightness was 9.7 (red) and 9 (blue no filter)compared to Eimmart's 8.7. Louderback thought that they observed an orange-yellow tinge. Cameron 2006 catalog ID=108 and weight=3.

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 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.

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.
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.
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.

The cameron 1978 catalog ID=230 and weight=3. The ALPO/BAA weight=3.
On 1979 Sep 15 at UT01:53 P.Madej (Newsome, Huddersfield, UK, 158mm reflector, x72 and x110, seeing II, transparency fair?) saw a small circular area of grey or white in the dark south end of Copernicus.The area showed up better through a Wratten 15 yellow filter, but was not seen at all through a purple Wratten 35 filter. P.W. Foley (Kent, UK), confirmed this but thinks that it is normal. Cameron 2006 catalog ID=68 and weight=1. ALPO/BAA weight=1.
On 1963 Nov 10/11 at UT 23:35-00:32 Kopal (Pic du Midi, France, 24" refractor) observed a TLP in Copernicus. Cameron says that the date maybe a misprint, should be 11/1/63? - sunset terminator at 25W and Copernicus in dark. The Cameron 1978 catalog ID=782 and weight=0. The ALPO/BAA weight=1.
On 1963 Nov 10/11 at UT 23:35-00:32 Kopal (Pic du Midi, France, 24" refractor) observed a TLP in Kepler. Cameron says that the date maybe a misprint, should be 11/1/63? - sunset terminator at 25W and Copernicus in dark. The Cameron 1978 catalog ID=782 and weight=0. The ALPO/BAA weight=1.
Grimaldi 1971 Jun 18 UTC 02:12-02:31 Observed by Jorgensen (Denmark, 36" refractor, 60, 200x, seeing good) "Dark reddish spot in SW part of crater. At 60x. Became clearer at 200x & seen in midwest also. At 0331h phenom. clearest in west, while S. region had faded. Air turb. & dawn ended obs. at 0331h. Seen best in yellow filter, well in red, invis. in green & blue." NASA catalog weight=3. NASA catalog ID #1298. ALPO/BAA weight=3.
On 1989 Jun 28 at UT 08:39-09:00 D. Darling (Sun Praire, WI, USA, 3" refractor, x36) discovered that at this time Mons La Hire was the brightest feature on the Moon. LaPrice was also very bright. Cameron quotes that Darling recorded that LaHire had a brightness of 7.0 and LaPlace=7.5. Darling did not think that this was a TLP. The Cameron 2006 catalog ID=369 and weight=0. The ALPO/BAA weight=1.
On 1989 Jun 28 at UT 08:39--9:00 D. Darling (Sunpraire, WI, USA, 3" refractor, x36) noted that promontorium LaPlace was very bright. LaHire brigtness was 7.0 and LaPlace was 7.5. Darling suspects that this was not a TLP because "as did not have mother-of-perl appearance as seen on Piton at times"The Cameron 1978 catalog ID=369 and the weight=0. 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.
On 1971 Feb 22 at UT 02:47-16:38 an Apollo ALSEP experiment detected an initial gas event in Fra Mauro. Sharp 4 second rise time, 1 hour delay time with 10 times increase in intensity. Molecular weight was between 14 and 20. Could have been Ne, Fl, O or H2O - the latter was thought best by Freeman. Duration of event 13 hours. The Cameron 1978 catalog ID-1284 and weight=5. The ALPO/BAA weight=5.
On 1986 May 05 G. North (Herstmonceux, Sussex, UK, 30" reflector) found that the crater (floor?) Plato was featureless, even during the better moments of atmospheric seeing conditions. A spectra was taken but nothing unusual was seen. The Cameron 2006 catalog ID=284 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.
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.
