     On 1970 Apr 11 at UT 22:04-23:00 Claudio Pamplona and Jackson 
     Barbosa(Fortaleza, Brazil, 2" refractor, x160, seeing=fair) 
     observed an obscuration over Peirce, in particular they could 
     not see the crater wall and the crater itself was like a black 
     pit. (Apollo 13 watch). The Cameron 1978 catalog ID=1238 and 
     weight=1. The ALPO/BAA weight=1.


2025-Jul-01 UT 04:05-04:31 Ill=34% Earthshine: sporadic meteors

2025-Jul-02 UT 03:19-03:31 Ill=44% Aristarchus observed by Unknown_Observer on 1969-5-22

     On 1969 May 22 at UT23:20 an unknown observer reported some 
     brightenings with pulsations in Aristarchus crater, Cameron suspects 
     atmospheric aberrations. This was during the Apollo 10 watch. The 
     Cameron 1978 catalog ID=1136 and weight=1. The ALPO/BAA weight=1.


2025-Jul-02 UT 03:19-04:40 Ill=44% Eudoxus observed by Nicolini on 1969-7-20

     On 1969 Jul 20 at 22:50-23:15UT Jean Nicolini (Sao Paulo, 
     Brazil, 12" reflector x430, S=II.5-III.5) saw a weak reddish 
     area on the north west(east?) wall of Eudoxus crater. An 
     English Moon Blink device showed it dark in blue and opaque in 
     red. Reddening remained unchanged while comparing it to 
     adjacent region and Aristotles. Colour index was toward dirty 
     orange. Colour most apparent in the good moments of seeing and 
     disappeared in the poorer moments of seeing, Cameron says that 
     this is opposite to what was expected if the effect was 
     atmospheric in origin and no colour was seen in Aristotles.
