    Note: The final elset shows this running as much as 7 min early against
    my final prediction. I suspect that this decayed a little beyond 
    perigee on this orbit, possibly to the S of the Tasman Sea between
    Australia and New Zealand. My calculations suggest that it should
    not have survived for another orbit, as per SpaceCom's analysis.
