2025-Aug-07 UT 21:06-21:38 Ill=97% Aristarchus observed by Foley_PW on 1976-1-15 *

     Aristarchus 1976 Jan 15 UT 19:30-20:50 Observed by P.W. Foley 
     (Kent, UK, 12" reflector) - Aristarchus was abnormally bright 
     (Cameron suspects that this is a confirmation an explosion 
     effect seen earlier by Greenland: "On 1976 Jan 15 at 19:45Ut 
     Greenland (Crawley, UK, 7x50 binooculars) thought that they 
     saw an "explosion" on the Moon (in the general region of 
     Aristarchus) for a fraction of a second, followed by a bright 
     spot in the same position (not an astronomer). After 
     discussions with others, decided it was a moment of transition 
     to greater intensity (better seeing?). Moore thinks it was 
     atmospheric but says it should be on record. Cmeron's 1978 
     catalog ID=1425 and weight=5". For the Foley report: Cameron 
     1978 catalog TLP ID=1427 and weight=5. ALPO/BAA weight=1.


2025-Aug-09 UT 21:49-00:01 Ill=100% Mare_Tranquillitatis observed by Culver on 1988-4-3 *

     On 1988 Apr 03 at UT02:25-02:30 Culver (Harker Heights, X, USA, Meade 
     2045 reflector, x40, seeing=turbulent) detected flashes coming from 
     just north of the centre of Mare Tranquilitatis. Some of these flashes 
     were of a duration of seconds whilst others were several minutes. 
     Altogether ~20 flashes were seen, and not in the same place. "5 small 
     star-like points could be located - and there were lots of craterlets". 
     The spots were "lined up E-W at N of 10 deg latitude." Colour was not 
     visible on these nor variations. Apparently the observer had seen this 
     type of TLP before but had not reported them. The Cameron 2006 catalog 
     ID=323 and weight=2. the ALPO/BAA weight=2.
