    A few hours ago Eutelsat 2-F1 (90-079B, 20777) did a number 
    of flashes visible without magnification, up to about +2.5.  
    
    Friday evening we were watching USA 39 (89-46A, 20066, a DSP 
    spacecraft) when I saw a bright flash to its right (north), 
    and soon Mike got that one in his scope.  He later identified
    it, and Saturday evening we observed it again for a good 
    while.  Its flash period is, um, either 54.50 or 27.25.  It
    has a phase shift, which I think was at about RA 23:10 more
    or less at about 4:10 on Dec. 12 UTC.  It's low in our WSW
    and drifting to the west from night to night.
    
    Mike's Molniya 1-53 (82-015A, 13070) is really neat!
    
    Thanks very much to Don Gardner for reporting Superbird 
    (89-47A, 20040) several days ago.  It's flashing very nicely 
    as always, and its rotation period seems to have speeded up 
    a little bit since it was last here.
