    In spite of passing sea-breeze clouds during almost the 
    entire session, Thursday evening (June 9 local time, June 
    10 UTC), there was quite a bit to see.
    At the somewhat early end of the session due to the clouds, 
    I looked for one more in the northwest.  To my surprise 
    there was a magnitude +1.5 (maybe brighter?) object to the 
    left of the pointer stars (west side of the bowl of the 
    Big Dipper, part of UMa).  It was moving quite slowly 
    higher up the sky.  It hit a star left of the bowl.  I 
    tracked it as it climbed higher and slightly south, and 
    just before a cloud got in the way, it hit a very close 
    pair of stars.  Findsat identified it as 14795, 84-012F, 
    NOSS 6(F).  Quicksat predicted the magnitude near the 
    first position at +9.1 (int. mag. +6.5).  The observing 
    site was BCRC, 30.315N, 97.866W, 280m.  Mike saw it also
    but had already begun putting away the telescope.  Here 
    are the two positions that I got (UTC, 2000 epoch, using
    HomePlanet to get the RA and Dec):
    4:40:25.05 - 11:16.1, +52.8
    4:42:22.85 - 13:09.9, +38.5
    Conjunctions.  I was tracking MSX (96-024A, 23851) and saw
    two others following it!  They turned out to be SPOT 2 
    (90-005A, 20436) and Adeos 1 Rk (96-046C, 24279).  Later 
    I looked for Terra (99-068A, 25994) and found two objects 
    traveling along together less than a degree apart.  The 
    second one was Astex (71-089A, 05560).  The expected and 
    observed conjunctions for the evening were two passes of 
    the NOSS 3-3 pair and a pass of the NOSS 3-1 pair (visible 
    without binoculars for some of the pass).  Both passes of 
    the NOSS 2-2 triangle were obscured by passing clouds.  
    Grace 1 and 2 don't really count as a conjunction, but 
    they once again got pretty bright in the northwest.
    Mike got HESSI (02-004A, 27370) in the telescope, and it 
    was flashing with a period of a little over one second.  
    Iridium 911 (97-030G, 24842) and 914 (97-030A, 24836) 
    have been putting on pretty nice flashing displays the 
    last several sessions, including earlier tonight.  
    I found 90007 flashing at about 2:28 UTC.  It appears 
    that its flash episode will soon be too early in twilight.
    Superbird A (89-041A, 20040) was too low -- behind a tree 
    for the telescope.  Right now it's probably flashing some 
    minutes before 3:00 UTC.
