    Note: The first of the two elsets above shows this running 2.6 sec late
    with respect to my final prediction. I have it decaying near the
    southbound equator crossing halfway around the orbit described by the
    second (final) elset, putting it over the eastern Pacific. SpaceCom's
    final notice has not yet appeared.
