    Since 90020 is considered "classified" I presume I can post regarding its
    My last post included what I believe to be a sighting of it based on the
    classfd.tle dated 05-30-2006:
    > At Adams Ranch Dark sky Site (+36.937,-96.650)
    > UNID just W of M16 in 36X (1.2 deg field) 
    This would be at about 18h 00m, -13.8 (M16 is at 18h 05m 00s -13d 51' 44")
    > slowly moving north, 3 periods through field of slow tumbling, mag 8 -> 10
    with > a rather sharp maxima.
    > Timing: 05-29-2006 05:10:32 UT
    > Seems to fit UNID 90020 in classfd.tle best of the tle's I have.
    My first question is whether anyone agrees this is a good match. I notice
    that the object I saw acted very much like the one Mike McCants reported on
    >> When I first spotted it, the object "flashed" every 2.25 seconds
    >> to magnitude 9 or 9.5.  "Tumbles" were visible in between the flashes.
    Other old posts seem to indicate there has been significant variation in its
    optical behavior and orbit:
    So the second question is whether there has been any advance in identifying
    the object?
