    I saw this unid Wednesday evening local time, July 
    10 UTC.  I don't get any good matches from Findsat.
    
    04:01:11 RA 16:15 Dec -3.0
    04:03:39 RA 17:40.5 Dec -13.6
    
    It was +5.5 magnitude and steady.  Location was 
    BCRC:  30.315N, 97.866W, 280m.
    
    Wednesday evening, watching Lacrosse 2, there was a 
    bright (+1.5) flash beside it.  I put binoculars on 
    the spot (a few degrees from the end of the handle 
    of the Big Dipper, maybe 14:10, +46) to watch for 
    more flashes, and the next one was close to the 
    same spot -- something moving quite slowly.  
    Findsat says it was Cosmos 1305 (81-088A, 12818).
    The flash period was maybe about 15 seconds.  After 
    a few flashes it went invisible.  Cosmos 1305 was 
    the victim of a launch failure.
    
    NOAA 14 (23455, 94-089A) is tumbling.  I first 
    reported this last August.  It was decommissioned 
    on 23 May 2007.  Being a payload, of course it has 
    the potential for spectacular flashes.
    
    Earlier tonight Cosmos 292 Rk (69-070B, 04071) was 
    tumbling slowly with a period of maybe about 25-30 
    seconds.  It was disappearing briefly on the minima.
    
    In watching for 90077 to appear, I saw a flash about 
    four degrees south of its predicted position.  It 
    was Gorizont 17 (89-004A, 19765).  Its maxima were 
    quite bright for a Gorizont, and Mike measured its
    flash period at 29.8 seconds, pretty fast.
    
    We've seen DSP F19 (Brad's unid, 25669, 99-017A, USA
    142) a couple of times lately, and it's spectacular!
    
    Three evenings lately I've watched a series of 
    Iridium flares low to very low in the WSW.  They are
    about 9 minutes apart, and each one is a few degrees
    lower in the sky.  They have been from magnitude +5
    (faint but definitely flaring) to one that was at 
    least -4.  I use Rob Matson's Iridflar.exe to run 
    predictions for these.  All of the flares have been
    reflections from the front MMA.  So, this is a way
    to see four or five of them in a row (mostly using
    binoculars due to their distance and atmospheric
    extinction).
