    Note: Eclipse entry occurs on the approach to southern apex at 7 deg S
    in the evening. It leaves eclipse while northbound near 5 deg N before
    dawn.

    Note: I have this decaying southbound over the southern Pacific on the
    last of my SatEvo-predicted revs, above.

    Note: Only the final one of the above three elsets seems reasonable.
    I estimate that it decayed on that orbit, possibly to the W of Perth,
    Australia, following a southbound equator crossing to the W of 
    Indonesia. SCC's final two reports have yet to appear.
