    Using my 8x42, after most of the LEOs were over with, I thought 
    I'd try to see Gorizont 13, especially since ASC 1 was fairly 
    nearby.  I saw a flash and then another, and I ended up watching 
    the area for about an hour, as there were three objects flashing 
    brightly in the area.  (My 8x42 has FOV of at least 8 degrees.)  
    This was a case when mounted binoculars would have been ideal.
    Then I could have used two stopwatches!  I'm 99.9% certain that 
    one of the three was indeed Gorizont 13 (86-090A, 17083), and it 
    appears that the other two were ASC 1 (85-076C, 15994) and 
    GStar 3 (88-081A, 19483).  Here is a PPAS report for Gorizont 13, 
    which seemed unusually bright for a Gorizont:
    
    86- 90 A 04-05-17 05:04:06   EC  861.0 0.3  10 86.10  +4.0->inv
    
    What PPAs numbers mean: http://users.skynet.be/satimage/bwgs/ppasformat.txt
    
    I only saw a few flashes of the other two.  They both have longer
    flash periods.  The last flash that I saw from the one I think 
    was GStar 3 was probably at least +2 magnitude.  One as yet 
    unidentified southbound LEO or MEO went through the FOV while I
    was watching these.
    
    Iridium 914 (24836):
    97- 30 A 04-05-17 02:48:16   EC   93.5 0.1   8 11.68  
    
    For it, I got this probably coincidental sequence of six flashes:
    
    11.62, 11.69, 11.74, 
    11.62, 11.69, 11.74 
    
    Orion 3 did a monster flash of about -5 or maybe even -6 
    magnitude at about 2004-05-17 03:10:32.
    
    Anyone seen Superbird A (89-041A, 20040)?
    
    The comet was faintly visible without binoculars.
