    SpaceCom is posting decay warnings for one of two recently catalogued
    auxiliary motors that were launched last year. The following is lifted
    directly from my Decay Watch page...

    Note: There is a possibility that this could decay during a pass across
    the south-western USA that (according to final elset of the above SatEvo
    prediction) carries it near Sacramento, CA, at 11:16 UTC, Las Vegas, NE,
    at 11:18, and Phoenix, AZ, at 11:19. Given the very high drag, though,
    the times and track are uncertain.
