    Returning from a public event at my astronomy club, I was just in time to search for USA
    161 22:28 to to 22:48 UTC.
    At 22:45:43 I had a mag 4 steady object pass below Polaris, direction relative to the
    vertical matching predicted orbits.
    ten second later I measured it traversing the 5 deg FOV in 3.7 s - too fast for USA 161.
    At 22:46:38 I found the first identifyable asterism (95% certainty?)
    26934 01 044A   5919 G 20100424224638000 28 25 0311153+565709 48 S+050 10
    
    This would make it about 9 min late on Russell-Ted elset, 5 min early but a lot off-track
    on mine.
    I find only one matching time/position in classfd+catalog_3l_2010_04_25_am, but going in
    the opposite direction.
    
    At 22:31:14 I saw three bright flashes, matching the characteristics of my Apr.19 obs (but
    fainter)
    The first one was above Polaris, the last one to the right, so it was most certainly NB.
    On Apr..19 the closest match was Topex/poseidon, last night a very unlikely Cosmos rocket.
    
    Around 22:41:47 a mag +2 NB UNID was passing "near" the head of Draco, fading in the NE
    "Best" match is 99-025 DEC !?
    
    Observations are, as I always do, reported in IOD format:
