    Ed,
    
    May be I saw this object recently. I did not yet identify it.
    I just remember such an object with about that flashing period in a
    Globalstarlike orbit.
    This means that this payload obviously lost its attitude control and might
    be no longer usable.
    Nice for us. More (Globalstars) to follow?
