    The #26606 decay is happening more quickly than I predicted. See my
    Decay Watch page for more details...

    Note: The latest elset shows it running 15 sec early against yesterday's
    prediction. I now estimate that this will decay near the northbound
    equator crossing at the end of the final SatEvo-predicted rev above and
    to the south of California over the eastern Pacific. The track continues 
    in daylight across southern Mexico to reach Tampa, FL, at 18:17 UTC.
