    Observed one-power TDF 1 (88-98A, 19621) flashes last night 
    (2000 Feb 14 UTC) from 2:49:04 to 2:54:11, when its position 
    went from about RA 5h 09m, Dec -5.00 to RA 5h 14m, Dec. -4.93 
    (2000).  They were three full periods, then seven half-periods, 
    then three full periods.  (It is possible that there was one 
    more one-power flash before my first one, but at that moment I 
    was observing in binoculars.)  The middle flash (4/7) of the 
    half-period ones was at about 2:51:45.4.  That's very close to 
    Mike McCants' estimate of it flashing about 12.5 minutes later 
    each night.
    
    At least during the last several nights, the flash period has
    been accelerating significantly.  A few days ago Mike wrote:
    
    ] The timed period of Feb 6 was 33.00, the timed period last 
    ] night was 32.71 seconds.  This difference of 0.29 seconds is 
    ] "not a mistake".

    Last night I got a flash period of 32.27 seconds (hopefully at 
    least reasonably close to Mike's results, since he was using a 
    telescope!):

    The observing location was BCRC, 30.314N, 97.866W, 270m.
