     On 1994 Apr 23 at UT02:41 D. Fryback (Madison, WI, USA) observed a 
     starlike flash in Alphonsus crater. The ALPO/BAA weight=2. 


2025-Aug-06 UT 04:32-07:57 Ill=89% Vallis_Schroteri observed by Clementine on 1994-4-23 *

     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. The ALPO/BAA 
     weight=1.

     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.

     U.S.A. reported a contrast effect and brightening in the crater 
     Proclus. 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.

2025-Aug-15 UT 08:13-09:33 Ill=60% Aristarchus observed by Hall on 1965-11-15

     Aristarchus 1965 Nov 15 UTC 05:55-10:00 Observed by Hall, Johnson, 
     Nordling (Pt. Tobacco, MD, USA, 16" reflector x400), Genatt (Greenbelt, 
     MD, USA, 6" refractor, x50 & 20" reflector x400), Wagmann (Pittsburgh, 
     PA, 30" refractor). "Color on c.p. detected with Trident MB, not seen 
     vis. at Port Tobacco. Network alerted & 6 responded. 4 did not see 
     anything unusual; 2 others did & saw red on c.p. in 6-in refr.. but not 
     in 20-in refl. at 400x; other saw indistinctness. Port Tobacco obs. 
     took 5 rolls of film in blue & red & neutral. Phenom. not detectable on 
     them, but focus was poor. Blue image had most detail, whereas would 
     expect red or neutral to. Phenom. still present at dawn in Moon Blink 
     device." NASA catalog weight=5. NASA catalog ID #914.

2025-Aug-15 UT 09:03-10:43 Ill=59% Plato observed by Mobberley_M on 1982-8-11

     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.


2025-Aug-15 UT 09:23-11:14 Ill=59% Alphonsus observed by Kozyrev on 1958-11-3

     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;

2025-Aug-15 UT 11:51-13:14 Ill=58% Aristarchus observed by Sage_VA on 1978-10-23

     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.


2025-Aug-16 UT 10:58-12:54 Ill=47% Plato observed by Arsyukhin on 1981-12-19

     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.

2025-Aug-17 UT 11:03-12:45 Ill=36% Copernicus observed by Madej_P on 1979-9-15

     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

2025-Aug-19 UT 09:24-11:23 Ill=17% Mare_Crisium observed by Arsyukhin on 1982-11-11 *

     On 1982 Nov 11 at UT 17:00-17:30 E.V. Arsyukhin (Moscow, Russia, 3" 
     reflector) saw three stationary dark spots suddenly appear in Mare 
     Crisium. There was one on the north and the other two in the south west 
     to south. They lasted approximately 30 minutes and then promptly 
     vanished. Cameron says that it cannot be this date because the Moon was 
     not visible at 17:00UT Suggests 05:00-05:30UT? The Cameron 2006 catalog 
     ID ID=189 and weight=3. The ALPO/BAA weight=2.

     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.


2025-Aug-20 UT 12:17-13:20 Ill=8% Plato observed by North_G on 1986-5-5

     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
