    This enters eclipse near a southbound equator crossing in the evening
    and it exits eclipse while northbound near 48 deg S in the morning.

    Final elset:

    The final elset shows this running 22 sec late against the prediction I
    had posted a few hours before. My SatEvo analysis gives me the following
    prediction over the final revs...
    EchoStar 6 Centaur r                             1074 x 92 km

    I estimate that re-entry occurred following perigee on the second
    of these revs, over the S Pacific.

    The latest elset shows this running 38 sec early against yesterday's
    prediction. I show it decaying northbound off the coast of Angola,
    southern Africa, near the end of this final predicted orbit...
