     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.


2025-Apr-05 UT 23:09-00:30 Ill=59% Proclus observed by Cook_MC on 1993-5-28

     telescope, x80-x130, atmosphere hazey - poor transparency) noticed that 
     the east side rims were slightly fuzzy and suspects that this might 
     have been due to the illumination angle. A.C. Cook (Frimley, UK) 
     obtained some CCD images that revealed that the effect was to some 
     extent still there one hour later. The Cameron 2006 catalog ID=461 and 
     the weight=5. The ALPO/BAA weight=2.

     large compared to central peak (@ approx 30km diameter)
     with intensity much different from other parts. Brightness
     between walls and shadowed floor. Would take 3 minutes to
     collapse, so continuously fed. 13-14 days later, at SS,
     central peak was normal. Kuiper took photos after Kozyrev's
     observations, but saw nothing abnormal. Drawing. Haas saw

     in brightness of Mons Piton point D (his designation) during 04:56-
     04:59. The whole of the east slope was affected - initially bright and 
     then faded and there was a blue colour (detected with filters). The 
     variabilty was 8-11sec (Cameron suspects atmosphere as the altitude was 
     low). The brightness stabilized at 05:12UT, but variability resumed 
     until observing finished. As a comparison Aristillus was not seen to 
     change. The Cameron 2006 catalog ID=287 and the weight=1. The ALPO/BAA 
     weight=1.

     On 1967 May 20 at UT 21:05-21:20 Kelsey (Riverside, CA, 8" reflector, 
     x300) using an English Moonblink device found colour on the south west 
     part of the floor. Note that for the times given by Cameron, the Moon 
     was below the horizon from California - so possibly these are local 
     times and these times need to be correctly converted into UT? The 
     Cameron 1978 catalog ID=1037 and weight=3. The ALPO/BAA weight=1.


2025-Apr-09 UT 20:36-21:28 Ill=91% Plato observed by Foley_PW on 1983-7-21

     On 1983 Jul 21 at UT 21:02-23:18 P.W. Foley (Kent, UK, 12" reflector, 
     seeing=III) found the region around the cleft on the souther rim to be 
     out of focus - however atmospheric conditions were turbulent until 
     23:18UT. An unsual dark triangular region (long base against rim) was 
     seen to extend from the inner rim at 12 o'clock onto the floor for 13-
     16km. The crater had lots of detail elsewhere. M. Cook (Frimley, UK) 
     found the south east to soth west to be obscured again, but not as 
     badly as she had seen on the 20th July. J. Cook (Frimley, UK) found the 
     dark region had 2 white bands on the side and the south west wall was 
     blurred like it was on the 20th July - this time tough colour was not 
     present. There were also two light patches on the floor. Mosely 
     (Coventry, UK) observed the south wall at x120 and found the wall out 
     of focus at the 11 o'clock location. Through a yellow filter he saw a 
     "white mistiness: on the top of the southern rim and only the south 
     east cleft could be seen (no colour). By 22:40-23:00 the effect had 
     cleared up. No dark triangular patch was seen. When Marshall (Surrey, 
     UK) observed (22:30-03:00) nothing unsual was seen, though a sketch 
     provided shows a light patch on the floor located at 11 o'clock. All 
     observations, made by all observers had some atmospheric turbulence, 
     however trsnparency was good. The Cameron 2006 catalog ID=225 and the 
     weight=5. The ALPO/BAA weight=3.

2025-Apr-09 UT 22:11-23:20 Ill=92% Gassendi observed by Foley_PW on 1976-11-3

     On 1976 Nov 03 at UT20:00-21:40 P.W. Foley (Kent, UK) reported a TLP in 
     Gassendi - some obsevers detected colour, others did not. P. Moore did 
     not notice anything unsual earlier at 18:50-19:00, though his seeing 
     was IV-V. Nor did he see anything unsual from 21:53-00:20, but seeing 
     was still IV-V. D. Jewitt, observing 20:34-21:25 and 22:55-23:20 also 
     reported nothing unusual. Amery (Reading, UK, 25cm reflector, x300) did 
     however notice a small reddish spot to west of central ridge, but by 
     20:30UT the colour was less obvious, but the spot was back again at 
     20:45, but not easily seen at 21:00 and gone completely by 21:45UT.  
     N.Bryant (Ilfracombe, UK, 25.4cm reflector, x260), observed 3 red 
     patches on the floor between 20:54 and 21:31UT. A BAA Lunar Section 
     report. ALPO/BAA weight=3.


2025-Apr-09 UT 22:59-00:25 Ill=92% Aristarchus observed by Barr on 1963-11-28

     On 1963 Nov 28 at UT 00:30-01:45 Barr, Greenacre, Hall and 
     Dungan (Flagstaff, AZ, USA, 24" refractor, and 69" reflector) 
     observed pink on the outer SW rim and a red spot towards the S of 
     this. A red spot was seen on the eastern side of Vallis Schroteri
     but only by Barr and Dungan. Other features checked for 
     atmospheric spectral dispersion and chromatic aberation - but the 
     colours in Aristarchus were not due to these. Smaller 12" scope 
     checked but no effects seen - presumably due to resolution and 
     image contrast issues? Pink on the SW rim may have been seen in a 
     69" scope by Boyce and Ford. ALPO/BAA weight=4.


2025-Apr-09 UT 23:22-00:44 Ill=92% Aristarchus observed by Robinson_JH on 1980-8-22

2025-Apr-09 UT 23:22-00:44 Ill=92% Manilius_B observed by Robinson_JH on 1980-8-22

     On 1980 Aug 22 at 02:15-21:29UT J-H Robinson (Teighmouth, Devon, UK, 
     12" reflector, x200, seeing=II) noticed in the area south east of 
     Manilius that it was brighter in red light than in blue light at 
     20:15UT whereas 1 minute later it was the same brightness in each 
     filter. The effect reappeared at 20:21UT and was particularly strong at 
     20:32UT. Foley (Kent, UK) verified this at 21:01UT - the blink area was 
     of high reflectivity in white light and was bright in red at 21:15UT, 
     thougjh the south east area stopped giving a colour reaction at 
     21:25UT. Madej (Huddersfield) found Manilius B to be norm al at 23:52UT 
     however at 23:55UT it was surrounded by a transient white ring that 
     varied in visibility in an irregular way. Foley found Manilius B had a 
     vivid blue interior and in blue light the ring was black. and not at 
     all seen in red or white light. The CED brightness measurement varied 
     from 1.9 to 2.4. All other regions observed were normal in brightness. 
     Violet was seen on the west wall of Aristarchus though. M.Price 
     (Camberley, UK) found a possible blink in Manilius B but was observing 
     under poor seeing conditions. Cameron 2006 catalog ID=105 and weight=5.

2025-Apr-10 UT 21:33-21:37 Ill=96% Promontorium_Agarum observed by Louderback_D on 1980-9-22

     On 1980 Sep 22 at UT05:00? D. Louderback (South Bend, WA, USA, 8" 
     reflector, x140 and 2.5" refractor) observed in Promitorium Agarum that 
     one of his pre-designated points, called "A", through to "C and "D" was 
     at least 5 brightness points brighter in red than in blue light. The 
     reverse was true on Sep 25th. Tonight the red seemed to be on a narrow 
     strip on the western edge. The Cameron 2006 catalog ID=109 and the

2025-Apr-10 UT 21:33-22:15 Ill=96% Aristarchus observed by Cook_AC on 1987-9-5

     On 1987 Sep 05 at 20:55UT A.C. Cook (Frimley, UK, 90mm questar 
     telescope, x130, seeing III-IV, Moon 16 deg in altitude) observed a 
     dusky dark gray area just north of Herodotus and just south of the 
     Cobra Head. The interior shadow on the east of Herodotus by comparison 
     wad black and distinct. No change was seen when viewed through a 
     rotated polaroid filter. Apparently D. Darling (Sun Praire, WI, USA) 
     was observing at the same time but had better observing conditions and 
     could see detail in this region, suggesting that it was not a TLP. 
     There is no Cameron entry for this report. The ALPO/BAA weight=1.

     III seeing, 12.5" reflector) "Intensely bright craterlet south of central 
     peak, surrounded by a luminous nimbus. Foley (Kent, UK, 12" reflector)onfirmed 
     the crater was highly luminous at 21:20, and surrounded by a blue halo that 
     had a darker blue band within it. This craterlet faded over time, and by 21:20 
     Moore considered that it was no longer prominent, by 21:22 Foley confirmed the 
     reduced brilliance, and by 21:30 Moore considered it to be perfectly normal.

     the previous night". Its diameter is less than 3"
     (5-6 km) as judged by comparing with the angular diameter
     of Jupiter and also Jupiter's third satellite (the
     diameter of the active part of the volcano was at least
     twice the angular diameter of Jupiter's Moon). The shape
     was an irregular round figure with very sharply defined edges.
     It resembled a small piece of burning charcoal, when it is covered
     by a thin coat of white ash. The other two volcanos were 
     much further towards the centre of the Moon and 
     resembled large faint nebulae that are gradually
     much brighter in the middle; but with no well defined luminous
     spot within them. These three spots are plainly to be
     distinguished from the rest of the marks upon the Moon;
     for the reflection of the Sun's rays from Earth is, in its present
     situation, sufficiently bright with a ten-foot reflector, to
     show the Moon's spots, even the darkest of them. Such
     similar phenomena were not perceived in the previous month,
     despite using the same telescope. The volcano was not as bright
     as his 4th May 1783 sighting (resembling a 4th magnitude star as
     seen with the naked eye), though the latter was smaller in diameter.
