    Steve LaLumondiere reported an object with a flash period of 
    2.5 seconds at these positions:

    Thank you very much, Steve, for the reports!
    Kevin Fetter notes that it sounds like a DSP.  I agree.  When 
    we last looked for this one (which as seen from here would 
    begin to flash each night at about 04:00 UTC):

    it was no longer there.  I don't know if it was moved or just 
    set adrift.  But using the above very old elements, it is 
    predicted to be fairly near the above positions at about 05:00 
    UTC.  Orbital analysis (which I'm not qualified to do!) would 
    probably determine right away if the above positional reports 
    could possibly match the above element set (given proper 
    Earlier tonight I watched Superbird A (89-041A, 20040) from 
    about 3:53:30 to 3:59:37.  It's pretty far west of here now.  
    Good old Superbird!
    Hoping to see Discovery and ISS again later this morning, but 
    the weather is in doubt.
