     catalog is 09:30 which is in daylight here in the UK - possibly the 
     catalog is wrong, else the observer was observing in daylight, but 
     worth checking out just in case}. NASA catalog ID No. #433 and NASA

2026-Jun-19 UT 19:56-20:13 Ill=28% Aristarchus observed by Grego_P on 2010-4-18

     On 2010Apr18 at UT 20:45-21:00 P. Grego (St Dennis, UK, 17" 
     reflector - first practice run) observed that Aristarchus in 
     Earthishine was the brightest that he had seen it before. The 
     effect had faded to normal in the next 15 minutes though. "The 
     bright spot was initially thought to be part of the wall of 
     Aristarchus, but on closer examination the spot was probably the
     crater’s central peak. At around this time I estimated the 
     brightness of the peak to be around magnitude 8, but this is a 
     poor estimate as no suitable comparison stars in the immediate 
     vicinity of the field of view were to be seen. Aristarchus’ 
     outline was visible, as was a clearly defined sweep of 
     brightness to its west (presumably the high albedo markings 
     southeast of Herodotus) and another illuminated area to the 
     north of Aristarchus (presumably the Vaisala area), and a small 
     illuminated patch on the eastern flanks of Aristarchus. No other 
     areas of the Moon in earthshine appeared to be as bright as 
     these markings, and there were certainly no other clearly-
     defined spots as brilliant as the one that lay in Aristarchus. A 
     watch was kept until 22:00 UT, when the Moon went out of view 
     behind a tree. During this period it appeared that the spot was 
     becoming less bright and less clearly-defined, although the 
     other albedo markings in its vicinity remained visible; this may 
     have been a consequence of the Moon’s diminishing altitude. 
     ALPO/BAA weight=1.

     Piton 1960 Dec 26 ? UT 00:00? Observed by Schneller (Cleveland, OH, 
     USA, 8" Reflector, x53), "Red obscuration; less intense than Nov. (date 
     not given, but discussion suggests near SR, therefore Dec 28th most 
     likely date -- ancill. data given for 28th)." NASA catalog weight=3

2026-Jun-22 UT 19:19-19:39 Ill=59% Atlas observed by Theiss on 1973-4-10

     Atlas 1973 Apr 10 UT 18:37-19:49 Observed by Theiss (51N, 9.67E, 75mm 
     refractor, T=2, S=3) "N. wall of Atlas was yellow-green, several 
     magnifications tested with the same results"  - Hilbrecht and Kuveler,

2026-Jun-22 UT 19:19-20:17 Ill=59% Beer observed by Darling_D on 1978-11-8

     On 1978 Nov 08 at UT03:00 D. Darling (Sun Praire, WI, USA, 
     12.5" reflector, x95, seeing 8/10) saw near Beer and 
     Timocharis (11W, 30N) a bright flash inside the dark area. It 
     appeared like a diamond twinkling in sunlight and was somewhat 
     dazzling to the eyes. Cameron wonders in this was a meteor? 
     The Cameron 2005 TLP catalog ID=39 and weight=2. This is an 
     ALPO observation. The ALPO/BAA weight is 3.


2026-Jun-22 UT 19:19-19:32 Ill=59% Atlas observed by Darling_D on 1991-4-22

     On 1991 Apr 22 at UT 02:03-02:14 D. Darling (Sun Praire, WI, USA, 
     12.5", x99, seeing 7/10) found, using a red and blue Moonblink 
     device that Atlas crater gave a blink, the dark spots inside the 
     crater have a dark nucleus in the blue filter. This effect was 
     not detected earlier that night. The Cameron 2006 catalog then 
     says "Atlas normal". The Cameron 2006 catalog ID=424 and the 
     weight=3. The ALPO/BAA weight=2.


2026-Jun-22 UT 19:19-00:00 Ill=59% Alphonsus observed by Knott_J on 1993-3-30

     On 1993 Mar 30 at UT19:35-21:15 J. Knott (England, UK, 8.5" reflector, 
     x180 and x216, seeing=II and Transparency=good) observed at 19:35 the 
     central peak of Alphonsus appeared to be extra bright although was 
     normal later, however the observer suspects that this was a contrast 
     related and was not confident to send out a TLP alert. The Cameron 2006 
     catalog ID=458a and 458b and weights=0. The ALPO/BAA weight=1.


2026-Jun-22 UT 19:19-20:31 Ill=59% Torricelli_B observed by Gray_R on 2002-10-14 *

     Torricelli B 2002 Oct 14 UT 02:58-03:43 Observed by Gray (Winnemucca, 
     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.


2026-Jun-22 UT 19:19-20:08 Ill=59% Mare_Crisium observed by Brook_C on 2009-4-2

     On 2009 Apr 02 at UT 21:45-22:05 C. Brook (Plymouth, UK, 
     5" refractor, x40 and x100, using red and blue gelatine 
     Edmund Optics filters (rose No. 47 and blue No. 80), 
     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 19:19-19:21 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.


2026-Jun-22 UT 19:30-20:33 Ill=59% Aristillus observed by Pasternak on 1973-4-10

     Aristillus 1973 Apr 10 UT 20:18-20:24 Observed by Pasternak (53.33N, 
     7.5E, 75mm refractor, T=3, S=3) "Faint reddish area at the SE wall of

2026-Jun-23 UT 19:20-20:23 Ill=69% Plato observed by Moore_P on 1952-4-3

     Plato 1952 Apr 03 UT 20:45-21:30 Observed by Wilkins and Moore 
     (Meudon, France, 33" x460) whilst checking up on a 1923 28" 
     refractor sketch by W.H. Stevenson's, thry failed to detect a 
     prominent floor craterlet (featured in the 1923 sketch) just 
     inside the W wall. They suspected an obscuration. 
     Interestingly the whole floor was was reported to be lacking 
     in detail many hours later as observed by Cragg in the USA. 
     NASA catalog weight=5. NASA catalog TLP ID No. #550. ALPO/BAA 
     weight=2.


2026-Jun-23 UT 19:57-20:23 Ill=69% Torricelli_B observed by North_G on 1989-6-12

     On 1989 Jun 12 at UT 21:18-22:25 G. North (Herstmonceaux, UK, 
     Coude, seeing=V) noted at 21:18UT that Torricelli B was 
     "barely visible"- possibly this was seeing related. M. Cook 
     (Frimley, UK, 8" reflector, seeing=IV) found Toricelli B to be 
     ëxtremely dull - impossible to judge shadows on floor in 
     contrast to Cens." Holmes (Rockdale, England, UK, 8" 
     reflector, seeing=II-III) at UT21:30 also found Toricelli B 
     difficult to find at magnifications less than 200x. Cameron 
     comments that "Dulling is common on it at high Sun but 
     illumination doesn't seem to be the cause or related". The 
     Cameron 2006 catalog ID=365 and weight=5. 
     The ALPO/BAA weight=2.


2026-Jun-23 UT 20:08-20:23 Ill=69% Plato observed by Cross on 1970-4-15

     Plato 1970 Apr 15 UT 05:38-05:40,05:51-05:53 Observed by Cross 
     (Las Cruces, NM, USA, 108mm Schiefspiegler or 152mm refractor, 
     S=6, T=5.5=VG). The observer noted a lack of detail inside the 
     crater floor, despite visibility of detail outside the crater. 
     Spectra were normal for color. (obs. similar to historic 
     reports. Apollo 13 watch?)" NASA catalog weight=1 and catalog ID 
     #1253. ALPO/BAA weight=2.


2026-Jun-23 UT 20:13-20:23 Ill=69% Timocharis observed by Bentley on 1969-4-25

     Apr 25 UT 20:20 Observed by Bentley (England, 8" rteflector

2026-Jun-24 UT 19:20-00:00 Ill=77% Eudoxus observed by Unknown_Observer on 1882-2-27

     On 1882 Feb 27 at UT 18:30-19:30 an unknown observer reported an 
     unusual shadow in Eudoxus. Apparently the shadow was seen to be normal 
     on 1882 Feb 25 at UT 20:30-20:45. The Cameron 1978 catalog ID=228 and 
     weight=3. Reference: Sirius Vol 15, 167, 1882. The ALPO/BAA weight=2.


2026-Jun-24 UT 19:20-19:36 Ill=77% Eimmart observed by Pickering_WH on 1913-6-14

     Eimmart 1913 Apr 14 UT 01:00 Observed by Pickering (Mandeville, 
     Jamaica, 6.5" reflector) "By this date crater was clear  & at an albedo 
     ~5?. Drawings compare Jan. 16 & Aug.9, 1913." NASA catalog weight=3 
     (average). NASA catalog ID #344.


2026-Jun-24 UT 19:20-19:27 Ill=77% Manilius observed by Kern on 1972-5-22 *

     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" - 
     Hilbrecht and Kuveler, Earth, Moon & Planets, 30 (1984), p53-61.


2026-Jun-24 UT 19:20-19:36 Ill=77% Plato observed by Cook_MC on 2009-4-4

     On 2009 Apr 04 at UT 21:40 M.C Cook (Mundesley, UK) after receiving a 
     telephone alert call, examined Plato crater. Although she did not 
     report C. Brook's slight mottled pink on the floor of Plato, she did 
     report through that the floor patches looked darker than normal, 
     especially in blue light and in red they were not visible at all. In 
     white light they were darker than normal. A.C. Cook was probably 
     observing at the same time via a couple of remotely controlled 
     telescopes in Aberystwyth. The results (time lapse imagery 
     through narrow band filters) will be examined at a later date.
     Note that this observation was made after C. Brook said that he could
     no longer see his TLP. Therefore this constitutes a different TLP
     as there had been a gap of 1 hour since the last TLP report.


2026-Jun-25 UT 19:20-22:45 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 21:14-23:03 Ill=85% Gassendi observed by Cook_AC on 1979-12-29 *
