    The SESat aux motor probably did not decay over CA/NV/AZ, as hoped.

    Decay predictions:

    Latest (probably final) elset:
    SESat aux motor                                  827 x 90 km
    1 26710U 00019E   01055.48313291  .99999999  86451-5  49502-2 0   251
    2 26710  47.8214  69.8944 0539050  95.0521  37.7260 15.35888759  7032
    
    Note: The final elset shows it 3.6 min late against the prediction
    I posted a few hours before. The epoch of that elset is close to
    its pass over the SW USA when a decay had been possible. I now estimate
    that it decayed almost one orbit later, southbound over the NW
    Pacific and well to the N of Hawaii. SpaceCom's final notice has
    yet to appear.
