    This approximate solution is in close agreement with the satellite trail in two
    of the images taken from Tehran by Babak A. Tafreshi on 2007 Jun 15 near 17:32
    UTC, Ed Cannon's position of 2007 Jun 16 at 02:21:44.2 UTC, and several radio
    observations during Jun 15 and 16 UTC, received from www.uhf-satcom.com. Thank
    you to Bjorn Gimle for additional information and insights into Mr. Tafreshi's
    images.

    I suspect that the period may be about 0.5 s too low, so the object may run a
    little late. Track errors may exceed 1 deg, especially at high elevation.
    
    I am reasonably confident in this solution, but it remains to be confirmed by
    precise visual observations. Subject to that caveat, these appear to be the main
    deviations from nominal resulting from the anomalous final Centaur burn:
    
                       Nominal  Achieved
    Perigee, km         1000       776    
    Apogee, km          1200      1246
    Arg Perigee, deg     180       165
