    Note: The latest elset shows this running 6 sec late against the
    prediction I posted yesterday. With still almost a day to go, I show
    this decaying near a southbound equator crossing over NW Brazil. That
    orbit takes it southbound over the NE USA from Cleveland, Ohio, at 21:21
    UTC to Norfolk, Virginia, at 21:23.
