      30.334  -97.760  Austin, TX
    
    ***  2002 Sept 11  *** Times are AM UT

     1 40 43  30 200 270  2.6  285 191  517  89
    
    This object was very bright.  Ed Cannon estimated that it varied from 1.5
    to 2.5.  I assume that it is a fairing that covered the second payload.
    
    27517 H-2A R/B(1)   QS IM 1.5
     H  M  S  Al Azi Dir  Mag  Hgt Shd  Rng Phs
     1 40 52  30 200 270  2.1  285 190  518  89
    
    This object was also very bright.  Ed also estimated that it varied from
    1.5 to 2.5.  I was watching only this culmination spot through my
    12x80 scope, so I could not judge such bright magnitudes or see them
    vary in the few seconds that they took to pass through my field of view.
    
    27515 USERS         QS IM 5.0

     1 41  0  30 200 270  5.7  285 189  519  89
    
    This object was about 6th magnitude and steady.
    
    27516 DRTS          QS IM 3.5
     H  M  S  Al Azi Dir  Mag  Hgt Shd  Rng Phs
     1 41 27  30 200 269  4.2  286 189  521  88
    
    This object was fairly bright.  Ed said that it brightened
    up to mag 2.0 in the southeast for a few seconds.
    
    27520 H-2A DEB      
     H  M  S  Al Azi Dir  Mag  Hgt Shd  Rng Phs
     1 41 28  30 200 270       286 188  521  88
    
    This object was not seen.
    
    The decaying GPS PAM #22448 was not seen at 2:32 UT or 4:03 UT.
    
    Ed should also report:  Iridium 920 gave many bright flashes with
    a period of 0.6 seconds.  The Cosmos 2389 rocket has slowed a little
    from a 3.0 second period to a 3.2 second period in the last week.
