    Last night after briefly trying to see EUVE, I turned to
    look for USA 86 (22251, 92-83A), and I definitely found 
    it!  It took me a couple of seconds to be convinced that 
    the -1 object was it, but it was.  Then after a couple 
    of more seconds I started my stopwatch.  It maxed at 
    least as bright as Sirius and continued brighter than 
    zero for about 40 more seconds.  Then it fairly quickly 
    faded to +3 as it continued to the north.  The stopwatch 
    times were:  start, 1:49:05.5; stop, 1:49:45.2 March 10 
    UTC.  Location was outside my apartment -- 30.3086N, 
    97.7279W, 150m.  Not as spectacular as Dan Deak's super
    flare a few days ago, but a nice one for sure.
    
    Iridium 14 (24836, 97-30A) did quite a few one-power 
    flashes, and in binoculars it was pretty chaotic.  I'm
    not sure what to make of the times I got.
    
    After Seasat (10967, 78-64A) maxed at about +1, I looked 
    for Lacrosse 3 (25017, 97-64A), and it turned out that 
    they went within a few degrees of each other, both about
    +2.5.
    
    Two Long March rockets made tumbling one-power appearances 
    -- "CZ-3A Rk" (24799, 97-21B) and DFH-3 Rk (23416, 94-80B).
    
    The Moon, Jupiter and Saturn were in a very nice right 
    triangle!
    
    There had been considerable clouds early, but it cleared
    off pretty well early enough to see satellites, obviously.
