    The final 96072A point appears to be too early by about 0.3 s. Most
    likely, I hit the stopwatch early.
    
    SRP arc 27 of 99028A ended on 2002 Sep 01. This is my best fit elset for
    nearly the entire arc, 2002 Jul 19 - Sep 01:
    
    1 25744U 99028A   02244.03607639 -.00000060  00000-0 -91930-2 0    01
    2 25744  63.4458 103.9320 0238188 292.6815  64.9055  9.69782312    01
    
    WRMS error = 0.01 deg
    
    This elset fits the middle 15 days of SRP arc 27, 2002 Aug 03 - 17:
    
    1 25744U 99028A   02229.08427662 -.00000066  00000-0 -10197-1 0    06
    2 25744  63.4398 121.8167 0241320 291.5399  66.1335  9.69783845    06
    
    WRMS error = 0.01 deg
    
    The ndot/2 during SRP arc 27 was about as predicted, indicating a gain
    of energy.
    
    During SRP arc 28, 2002 Sep 01 - Oct 07, the orbit will be in constant
    sunlight; therefore, there should be little or no net energy change due
    to SRP. As a result, the object will become progressively early relative
    the above elements. It was measurably early, about 0.4 s, during
    tonight's observation.
