    Note: The latest elset shows this running 8 sec late against the 
    prediction I posted yesterday. The decay has slipped later.

    Note: The latest elset has this 9 sec late against yesterday's
    prediction. I predict that this will re-enter southbound over the SW
    Indian Ocean, to the SE of South Africa, on the last of these SatEvo-
    predicted orbits. It is possible that it will survive to re-enter
    northbound over the S Pacific later on that rev.
