    I had assumed that it would be months before we would get a 
    chance here to see Gravity Probe B, but Mike had predictions 
    and it turned out that in spite of clouds trying hard to end 
    the session very early, we did get to see it and its Delta 
    exit from the Earth's shadow.  GP-B was about +4.5 fairly 
    low in the NE, and the Delta was fainter, later, in the NW.
    PPAS reports on Cosmos 2082 Rk (20625), a big, bright Zenit, 
    from last night and some months ago:
    90- 46 B 04-04-23 03:09:19   EC  130.8 5.0   6 22     +2->inv
    90- 46 B 03-09-07 02:43:03   EC  298.7 3.0  19 15.7   +4.0->+6.0
    I saw a zero magnitude or maybe -1 flare in the northern head 
    of Hydra, a northbound object.  It was Meteor 2-18 (89-018A, 
    PPAS report for Intelsat 503 Centaur Rk (13007):
    81-119 B 04-04-23 03:32:00   EC  189.9 0.3  22  8.63 
    The session was ended somewhat early by very low rapidly moving
    northbound clouds.  The clouds earlier also blocked a pass of 
    Galileo IUS (89-084C, 20299) lower than 240 km and also 90019.  
    On the other hand, good old Okean-O Rk (99-039B, 25861) arrived 
    while there were a lot of clouds, but it stayed easily visible 
    in a hole for almost its entire pass.
    Site was BCRC: 30.315N, 97.866W, 280m.
