    Observations on Mar 13 UTC by David Brierley, enabled me to extend the arc:
    
    USA 193          5.0  2.5  0.0  4.4 v
    1 29651U 06057A   07072.16511080  .00019930  00000-0  14299-3 0    02
    2 29651  58.5015 100.1376 0007120  99.2043 260.9849 15.73100874    08
    Arc 2007 Mar 08.23 - 13.19, WRMS residuals = 0.035 deg
    
    Rate of decay is up a bit, probably due to increased geomagnetic activity on Mar
    11 and 12. Based on the mean rate of decay of the past few weeks, Satevo
    estimates decay from orbit in late February 2008.
