     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.

     NV, USA, 152mm refractor x114, x305, seeing Antoniadi III, transparency 
     good) "I was out this morning (2:58-3:43 UT, October 14, 2002) 
     observing Torricelli B. At 3:17 UT the west sunlit wall of the crater 
     brightened from an intensity (Elger Scale) of 5.0 to 9.0. In actual 
     terms it went from slightly less bright than the walls of Picard to as 
     bright as the sunlit west wall of Dionysius. This was observed at 114x 
     in white light, where all three craters were in the field of view 
     simultaneously. This event lasted less than a minute and no comparable
     brightening in Dionysius or Picard was seen. The wall of Torricelli B 
     returned to 5.0 in brightness. I continued to observe Torricelli B in 
     white light until 3:43 UT, but the brightness remained at 5.0. Before 
     the brightening I tried blinking Torricelli with the following 
     combinations of filters: Wratten Red 25 and Blue 38A, Red 25 and Blue 
     80, and Red 25 and Schott BG38 (Blue Green). Nothing showed up more 
     prominently in any combination except the Red 25-Blue 38A combination, 
     where Torricelli B became invisible in the Blue, probably because of 
     the filter density. Both the Blue 80 and Schott BG 38 seemed closer in
     density to the Red 25 than the Blue 38A is. I could not see any details 
     inside Torricelli B during this session, including the bright spot on 
     the NE rim." The ALPO/BAA weight=3.

     transparency poor due to thick haze. seeing was excellent) 
     observed that that the rays that crossed Mare Cisrium from
     Proclus were brighter in red light than in blue. A similar 
     effect was also observed, to a lesser extent south of the
     Mare. Non-mare Crisium rays from Proclus did not have this effect. 
     The TLP was not seen at the higher magnification of x100.
     The ALPO/BAA weight=2.


2026-Jun-22 UT 18:52-19:15 Ill=59% Ptolemaeus observed by Travnik on 2020-7-27

     Ptolemeus 2020 Jul 27 UT 23:00 N. Travnik (Brazil) observed 
     visually for 2nd time ever (first seen back in 1970), an 
     effect on the floor of this crater at local lunar sunrise: 
     "kind of glimmering mist lifted and wafted inside the shady 
     hollow of the crater". Almost certainly this is a combination 
     of atmopsheric seeing on the narrow shadow spires, but we 
     would like observers to look at this visually or obtain time 
     sequence images to try to replicate this effect. This report 
     is assigned an ALPO/BAA weight of 1 for now.

     Manilius 1972 May 22 UTC 20:10-20:40 observed by Kern (48deg 45'N, 8deg 
     45'E, 60mm refractor) "The SW inner wall became brighter at times" -

2026-Jun-25 UT 18:52-21:42 Ill=85% Plato observed by Crick on 1979-12-29 *

     On 1979 Dec 29 at UT 17:45-18:20 Crick (Merchtem, Belgium, 6" 
     reflector, x140, seeing=III) found a violet spot in the NW inner wall. 
     The floor was obscured of detail on the northern half. All other 
     regions studied appeared normal. Observer unsure if this was a TLP or 
     spurious colour. Cameron 2006 catalog ID=80 and weight=3. ALPO/BAA 
     weight=3.


2026-Jun-25 UT 21:14-21:42 Ill=85% Gassendi observed by Cook_AC on 1979-12-29 *

     Gassendi 1979 Dec 29 UTC 20:09-22:04 - Observer: Cook (Frimley, Surrey, 
     UK) "Colour seen - almost certainly spurious colour and not a TLP".
     ALPO/BAA weight=1.
