    I was fortunate to find the DSP 23 Centaur rocket last night
    under clear and dark skies.  It was fainter than expected -
    tumbling about once a second to about magnitude 11.5 or 12.
    Because of cirrus clouds over Austin and BCRC, I drove about
    30 miles south of Austin.  Revised elset:
    
    USA 197 Cn r  
    1 32288U 07054B   07315.89571404 0.00000000  00000-0  00000-0 0    06
    2 32288   3.9650 272.1000 0001000 154.0000 206.0000  0.99676600    02
    
    There is still some uncertainty in this elset because I cannot
    determine the eccentricity or argument of perigee from only two
    sets of observations and the mean motion is a little uncertain
    because the two sets of observations were for different parts
    of the orbit.
