    In the land of the Midnight Sun (soon; 800 km N of me) I
    was too tired last week to stay up long enough to see
    comet 2001Q4 (NEAT). I tried once, but it took me ten
    minutes to find any star between Jupiter and Venus
    (using 7*30), five more to identify them, and two more
    to find beta Cancrii, but no comet. Yesterday I was out
    from local midnight and saw it easily in 7*50 and
    20*200. Using 7*50 at maximum out-of-focus I estimated
    its magnitude at +5.0 (though the comparable gam Cnc
    was slightly more compact)
    
    23:08-23:14 UTC I had the track of ETS-6 above easily
    located beta Sct and lambda Aql, but saw no flash.
    
    Observed USA 161 in the scope:
    26934 01 044A   5919 F 20040515215843290 17 25 0033384+630762 99 S
    26934 01 044A   5919 F 20040515215844460 17 25 0035189+625936 55 S
    26934 01 044A   5919 F 20040515215914490 17 25 0132381+603469 28 S
    26934 01 044A   5919 F 20040515215958220 17 25 0229174+553205 97 S
    What these numbers mean: http://www.satobs.org/position/IODformat.html
    
    At 22:20:20 +- 20 s in lower Cephei I saw a single bright
    flash - could it be Nimbus 5 72097A ? Other satellites
    for which I took some approximate times and pos, and
    later identified: 22:20 70113B, 22:30 Iridium 43, 22:32 Cosmos
    1220 (very bright), 22:36 82059A, 22:56 83003B?, 23:03 83044A.
    
    Another UNID at 22:30, between CVn and eps UMa, thought to
    be Ir 43, but times and pos mixed-up. And one very
    faint, moving above gam Vir 22:57:50 in DIR=045 degrees?
