     transparency good) "Observations carried out of the area extending from 
     the Alpine Valley to the Crater Cassini. At 17:12 a pin point bright 
     flash was seen NW of the rim of the crater E in white light. A 2nd pin 
     point flash was also seen at 18:18, this time thru a blue filter. The 
     2nd flash was also seen on the NW rim of the crater E. The observer 
     does not think this was a TLP as the seeing was III, but the flash was 
     so bright as to be startling. Other peaks within the Alps were bright 
     but were much less so in red and ble filters, where the rim of the 
     crater E. NW edge was very bright in all filters, including white 
     light. Incoming cloud prevented further observation." BAA Lunar Section

     6) observed that an unoficially named mountain (Lambert Gamma or 
     Mons Undest), near Lambert, had a "very strong glow", especially 
     the part that was facing the line of the terminator and this was 
     brighter than the side facing away. The No other object nearby

     disk during a lunar eclipse. It is possible
     that the TLP referred to might have been

     In 1954 Jan 19 at UT 03:00 Porta (Mallorca, Baleares, Spain, 3" 
     refractor, x50) observed the following during a total lunar eclipse: "3 
     brilliant yellowish-white spots between Picard & Peirce. Phosphor. 
     light distinguished easily against gray-green background of mare. 
     Irreg., intermittent. Did not perceive them all dur. totality. Next day

2026-Aug-27 UT 09:25-09:26 Ill=99% Mare_Tranquillitatis observed by Searle_G on 1978-9-16

     On 1978 Sep 16 at UT 18:28-18:57 G.Searle (Concord, Sydney, NSW, 
     Australia, 8" reflector, x100, x160, S=III) observed a bright star-like 
     point on the western (IAU) edge of Mare Tranquilitatis (x100) that 
     appeared unlike any other crater and a check of the location revealed 
     no suitably bright crater in that region (from a map?). Changed to a 
     higher power (x160) and it was still there, but not as conspicuous. 
     Observer thinks that this may have been due to the Moon's low altitiude 
     (16 deg) and the seeing. At 18:35 he compared it to the brilliant 
     crater Proclus and found the star-like point to be 75% of the 
     brightness of Proclus. Ken Wallace (Australia) had been taking photos 
     and observed the object at 17:37.5UT. The object gradually faded over 
     the next 15 minutes and by 18:52UT could only be seen in averted vision 
     at x100. By 18:57UT it was gone. The Cameron 2006 catalog ID=38 and 
     weight=5. The ALPO/BAA weight=2.

2026-Aug-28 UT 02:44-00:00 Ill=100% Aristarchus observed by Kolovos_G on 1989-8-17 *

     On 1989 Aug 17 at UT 01:02-04:20 G. Kolvos (Thesaloniki, Greece, 
     4"reflector) measured (using photometry) that although there was a 
     gradual fade over the Moon as the eclipse progressed, there was a 2"% 
     rise in brightness of Aristarchus.Graphs were submitted and photos. 
     A.C. Cook supplied CCD images and CCD photometry. A photograph by 
     Conway (Sun Prarie, WI, USA) at the start of the eclipse reveal a 
     bright colourless spot (aparently confirmed). The Cameron 2006 catalog

     region of the crater and just north of it, become conspicuous and 
     increased in brightness from then on" Cameron thinks this is just the 
     edge of the shadow and possibly normal. Cameron 1978 catalog ID=268 and

     spots on the Moon during a lunar eclipse (including Aristarchus). At 
     23:50UT 3 of these patches emerged from the dark and appeared as bright 
     spots compared to other craters "Älbedo=10+". At 23:55UT a ray appeared 
     out of the north east rim of menelaus (Normal?). It appeared just 
     before the artea emerged and increased in brightness. At 23:58UT it 
     decreased and continued to do so. The north east edge of Menelaus 
     appeared very dark at the point that the ray was extending from SW edge 
     (a ridge there) and apperared to obscure features along its path 
     (Albedo=9). The Albedos of Manilius and Delambre were 8.5 at 00:05UT.

2026-Aug-31 UT 10:06-11:55 Ill=89% Macrobius observed by Gray_R on 2005-10-21

     On 2005 Oct 21 at UT 13:07-14:27 R. Gray (Winnemucca, NV, USA, 15cm F/9 
     refractor, x228, seeing 4-5, transparency 5-6) observed a possible TLP 
     in Macrobius. His report is as follows: "Blinked Macrobius with Wratten 
     Filters Blue 38A and Red 29. Macrobius became almost invisible through 
     the Blue 38A and essentially the same as in white light through the Red 
     29. The interior of the crater was completely in shadow. The only part 
     of the east wall that was visible was an apparent high point still in
     the sun and seen as a bright point of light. This faded into darkness 
     before 13:56UT. No sign of any illumination of the east wall crater 
     interior or the interior of the west wall was seen during the
     observation period. The outer west wall was a rough looking, 
     complicated mix of deep shadow and illuminated sunlit terrain." The 
     observer concluded that there was not a TLP - although he did get a 
     filter reaction, this may have been due to the different densities of 
     the filters? ALPO/BAA weight=2.
