    Hi again,
    
    Using the latest TLE (provided by Björn):
    
    ISS 0.25 d
    1 25544U 98067A   03100.80462084  .00021077  00000-0  28168-3 0  8787

    The new centerline track is:

    2003/04/11  1:32:30   39.2190    -82.1580
    
    ISS is now running 31 seconds later relative to yesterday's TLE, indicating
    a reboost must have happened in the last 24 hours.  Examination of the
    mean motion of the old elset shows this is the case:
    
    ISS
    1 25544U 98067A   03099.77720405  .00020500  00000-0  26546-3 0  8748
    2 25544  51.6352   3.8139 0004312  42.1567  60.1039 15.58858219250337
    
    The good news is that the transit is no longer a miss from Thomas's
    home coordinates.  If he moves north a smidge, he'll be right on the
    centerline.
