    Geomagnetic conditions were very disturbed earlier today and there is an
    auroral alert in force for July 21. This probably means that the decay
    dates for the two current decayers will shift earlier.
    
    I'll be unable to post any further Decay watch updates until after I
    return from holiday on the 29th, by which time both these objects should
    have decayed. While I am away, I hope that the
    dklist/select/iridiums/etc files available via my SatEvo page will
    continue to update automatically. However, today's update of my all-
    object satbase file is the last until after I get back.
