    Notes:
    ------
    
    (1) I believe this is the NROL-22 payload launched 28 June 2006.
    
        The satellite appeared variable with a period of about 5 seconds
        and ranged from magnitude +7.5 to about +8.0  Conditions were
        not ideal as there was high cirrus and a very bright moon close
        by. It was running about 5m 07sec late on the search elements I
        was using - epoch 06185.93724641 .
    
    (2) Many thanks to my radio tracking colleagues who made this observation
        and recovery possible,specifically Ivan Artner who put in many hours
        making doppler observations.
    
    Cheers
    Greg
