    Well, I've been a bit intimidated to post any of my extremely amateur
    satellite "data," but since someone mentioned Iridium #63 on 9/21, I
    thought I would relay a story about my first Iridium sighting.
    
    I have been trying to observe a flare for some time now.  You may recall
    earlier posts, I just couldn't seem to view one.  Iridium #63 was due over
    my area at 6:10:10 EDT.  I don't do any "observing" from my house, as I
    live in the suburbs of Utica, NY, and it's not a good place to look up
    from.  I have a very nice site from which to look at the sky about 15
    miles north of here, and that's the sky I'm familiar with.
    
    But, I had to be up at 5:30, and on my way to work by 6:15 that morning,
    so my driveway would have to do for #63.  I recalled someone here saying
    that the timing on these things is deadly accurate, so I wanted to check
    the time that a nasa time server was providing.  6:05 saw me still trying
    to connect to the Internet (terrible ISP, getting cable in a
    week)....6:07.......6:08......finally connected, queried the server, and
    saw 6:08:57.  My watch was 10 seconds fast.....
    
    Down the stairs to the front door, 6:09.....then I remembered.....177
    degrees azimuth, 57 degrees altitude......but where the h*** is 177
    degrees in my driveway??  I could haul back upstairs for a
    compas......6:09:59........okay, forget it.
    
    Outside, I knew where the ecliptic is, and guessed from there....looked
    up, and saw a nearly overcast sky.......6:10:05.......I was doomed.  But,
    just as I was about to look down......BAM.  I'm not good at guessing
    magnitudes, but there was a brief flash, had to be at least -6 (the center
    of the flash was 3.9 km east of me).
    
    Time stood still for about 30 seconds after that, while I imagined a piece
    of metal thousands of miles up bouncing light from 93 million miles away
    down onto my driveway.  It was my first sighting of an Iridium.  Totally
    awesome, to be scientifically accurate.
