    Note: The latest elset shows this running 4 sec early against 
    yesterday's prediction. I show this decaying southbound over Mongolia
    on the last of the predicted revs above. The preceding northbound
    arc takes it across the USA from Miami at 08:18 UTC to E of Detroit
    at 08:20. The following northbound arc carries it from Odessa, TX, at
    09:46 to NE Montana at 09:50.
