     On 1994 Jan 16 at UT19:30-21:10 D. Strachen (England, UK, 4" refractor, 
     x21 and x143) whist looking at an occultation of ZC3453, saw a bright 
     spot in Earthsine, just north of Aristarchus (47W, 25N) at position 
     angle 30deg-40deg, only a little way in from the limb. It appeared like 
     a star through haze and a few seconds of arc in diameter. It was 
     Visible for more than 1 hour until 20:50UT although had faded somewhat 
     by that time. However J. & M. Cook (Frimley, UK, 12" reflector, x143 
     and x244) saw nothing in Earthshine from UT 20:02-21:10. The Cameron 
     2006 catalog ID=472 and weight=1. The ALPO/BAA weight=1.


2024-Jun-11 UT 07:24-07:34 Ill=23% Promontorium_Agarum observed by Moore_P on 1995-2-4

2024-Jun-12 UT 07:25-07:33 Ill=32% Alphonsus observed by Wilkins_HP on 1949-6-1

     Alphonsus area? 1949 Jun 01 UT 22:06 H.P. Wilkins (Kent, UK, 6" 
     reflector x200) observed a bright white 1 sec stationary (mag 
     3?) flash in Earthhsine, close to the central meridian, and due 
     E of Theophilus (potentially in the general area of Alphonsus?). 
     The flash was approximately 6 km in diameter. ALPO/BAA weight=1. 


2024-Jun-12 UT 07:25-07:42 Ill=32% Peirce observed by Pamplona on 1970-4-11

     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.


2024-Jun-13 UT 07:26-07:42 Ill=41% 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. 
     Apollo 11 watch. Cameron 1978 catalog ID=1177 and weight=3. 
     The ALPO/BAA weight=3.

     Colourless to pink to reddish. Environs also involved. 
     Photographs were taken. (Apollo 13 watch). Cameron 1978 catalog 
     TLP ID 1241 and weight=3. ALPO/BAA weight=3.


2024-Jun-13 UT 07:26-07:42 Ill=41% Earthshine observed by Watson_W on 2005-7-13
