    This evening I saw the object "90019" a.k.a. "Unknown 031017"
    creeping through Aquarius.  At 2003 Oct 24 23:17.6 UTC, magnitude
    was about 5.9 (corresponding to quicksat intrinsic magnitude of 3.0
    and SkyMap standard magnitude 4.1).  At 23:19.2 UTC, it was about
    6.5 magnitude (quicksat intrinsic 3.5, SkyMap standard 4.8).
    
    In that interval, the astronomical phase went from 69 to 58 degrees
    and the range from 1790-1890 miles (2880-3050km).
    
    It appeared within a couple of seconds of time from predictions
    derived from the TLEs:

    Has anyone a clue as to what this [intrinsically] bright object "really"
    is?
    
    Clear and dark skies!
