    Kevin,
    
    my usual questions: Is the inserted time UTC? What is the FOV? Where is it?
    
    At 09:20 UTC I find 09880 at RA 10:00 Dec.-16 az 166 el 28
    The az is consistent with a slight upward motion of the stars (assuming the
    FOV was horizontal)
    The stars would pass the FOV in 3.1 minutes, so the FOV would be 0.75 x 0.57
    degrees
    At that pos, 09880 would move 2.0 deg/min, and it appears to pass the
    vertical FOV in 19 sec, which makes the vertical FOV 0.64 deg.
    (Or time is off, and the satellite was higher - 10 % slower 3 min earlier at
    34 deg el)
    Time from double flash #1 to #4 is ~12.7 s; full period 4.25 s?
    
    I hate to do these calculations to find data, some of which Kevin might have
    already.
