    Well, how disappointing!  We -- Mike, Fred, and I -- were not 
    able to find Double Star 1 with binoculars or finder scope!  
    (Mike thought he saw a couple of flashes.)  Maybe it's due to 
    the Sun being too far north now.  I had such high hopes based
    on previous passes observed.
    
    Intelsat 506 is flashing with a period of about 106 seconds.  
    It appears that it does two or three flashes, then a phase 
    shift (2.5 cycles), and then two or three more flashes.  It 
    seems that one or two of the flashes on each side of the 
    phase shift are very bright.  It's currently low in the WSW 
    and drifting to the west and flashing around midnight local 
    time (5:00 UTC).

    So many objects, so little time and energy to observe them....
    
    Mike has been trying hard to find 97-068B (25035), a lost 
    flashing Centaur.
