    Yesterday's Decay Watch posting reported the wrong latest/final elset 
    for #22780 = 93- 54 B = GPS 2-22 Delta 2 r - it should have been:

    Note: The latest elset shows this running 12 sec early against
    yesterday's prediction. I now show this decaying southbound over
    the Pacific, well to the S of Hawaii.
