    Denis V. Denissenko reported three unknown objects: 
    His flaring object of 2002 Aug 11 at 21:17 UTC was USA 161 (26934 /
    Of the two candidates Denis suggested for his second unknown, a flashing
    object, I believe that IRS-1A (88021A / 18960) is the more probable,
    because Russell Eberst observed it flashing with a 7 s period on 2001
    Sep 16 UTC.
    The third unknown may have been Seasat (78064A / 10967). It was trailing
    and below, but slowly rising, and for a time its angular velocity was
    greater than that of 88021A. Seasat was the most likely object to have
    reached the observed mag 2.5 to 3. 
    If by "almost crossed" Denis meant "moving in opposite directions", then
    the Meteor 2-13 (85119A / 16408) is a possibility. At 23:40:22 UTC it
    passed within about 1 deg of 88021A, moving in the opposite direction;
    however, the magnitude of the angular velocity of both was nearly
