    I received a privage message pointing out that in this 
    animation there is a bright, fast-moving crosser.  Mike 
    McCants identified that one as 31578, a Long March.  Beyond
    that, there are also five geosats (one way out of plane) 
    that appear in the lower right of the frame towards the end 
    of the animation.  I think those look like the group that 
    are around longitude 100 west, which is about azimuth 185-186 
    from here.
    I looked more closely and also believe that I see a dot very
    near the vertex of the "comet", but inside of it, as well as
    the obvious dot out in front of the "comet" -- all moving at
    the same rate.  Maybe the dot within the vertex of the "comet"
    is an image artifact?
    Finally (?), I noticed in at least three early frames around
    frame 7 that there is another object that comes in at the 
    upper right that also is moving at the same rate as the 
    "comet" et al.  It appears and then disappears after three 
    or four frames.  Perhaps it is an artifact?
