    I searched for USA 193 (29651/06-057A) +/- 2 minutes of time from a
    predicted pass, based on the (hobbyist-derived) TLE:
    
    USA 193          5.0  2.5  0.0  4.3 v
    1 29651U 06057A   08042.43411818  .00214910  00000-0  31472-3 0    05
    2 29651  58.4821  69.5983 0009338  66.1500 294.0578 16.04437931    07
    
    The only object I saw, using 10x50 binoculars, in the expected area,
    passed about 2 degrees below 5 xi2 CMa (the leftmost of two stars below
    beta CMa) and was a little fainter then that star. It passed within a
    second of time of predictions based on the above TLE and was the only
    object that Skymap found in the area using an alldat TLE set.
    
    I am very suspicious that this is unlikely to be USA 193 because:
    (1) It was a couple of magnitudes fainter than I expected (based on
        previous observations), and,
    (2) The observed pass agreed much too well with predictions from TLE
        with such a large drag term.
    
    So, for what it's worth, here's my approximate observation in IOD format:
    29651 06 057A   8840 P 20080216233501000 28 35 0639400-251000 18  +048 05
          
    
    Clear and dark skies!
