    Last night was our first really clear, moonless evening 
    in a while.  
    TDF 1 (19621, 88-98A), continuing to speed up, was about 
    31.2 seconds.  This might be our last chance from Austin, 
    as it was only about 17 degrees above the WSW horizon.
    88- 98 A 00-02-27 05:38:09.5 EC 1030.2 0.3  33 31.22  mag +2->inv
    My previously reported obs was:
    88- 98 A 00-02-19 04:02:47.6 EC  700.3 0.3  22 31.83
    This is an interesting object.  I observed two separate 
    episodes separated by a gap of up to ten cycles when I 
    couldn't see it using 10x50 binoculars.  Soon into the 
    second episode, I observed nine half-period flashes, some 
    of which were one-power.  A little later, I saw five 
    maxima with double flashes separated by about 0.3 second.  
    My cycle count for the PPAS report above ended before the 
    double-flash maxima, because they occurred on half-cycle 
    times in relation to earlier full-cycle maxima.
    I guess it will get into range for the western Pacific in
    a couple (?) of weeks.
    Cosmos 1867 (87-60A, 18187) was tumbling with period about 
    6.2 seconds -- but I only timed eight cycles.
    Some bright flashes from Iridium 79 (25470, 98-51D).  Its
    one-power flashes the last two times I've seen them have 
    been after culmination, as it was descending into the north.
    Location was 30.314N, 97.866W, 270m.  Well, actually, TDF 1
    was observed from in front of Mike McCants' house.
