    Last night Ed and I looked for a DSP in the same place that
    USA 39 normally occupied for many years.  I was able to find
    it about 4:00 UT and I tracked it for over 30 minutes in my
    8 inch telescope.  Some flashes were visible in my 12x80 telescope
    and some flashes were seen by Ed in his binoculars in spite of
    a first quarter moon in that part of the sky.
    An extrapolated orbit from last December with a mean motion of 1.0027
    was a very good match for Steve's observations and my observations:
