    I'm sure this is old news to most of you experienced satellite observers -
    By accident on the Fourth of July (July 5, 2013 5:37:00 UTC) while watching
    a fireworks display, several NASA friends and I saw ALOS coming up out
    of Scorpius heading toward the zenith.  It remained steady at about
    magnitude 1 for about 20 seconds, disappeared for 10 seconds,
    then FLARED to at least -10 magnitude for about 1 second.  Then the
    satellite faded, almost to the limit of visibility
    (about +4 mag from our urban area).  Then the cycle approximately repeated
    itself - got brighter for awhile, faded,
    then flared AGAIN to about -8 mag.  This repeated another full cycle with
    another -8 flare as the satellite headed far to the north.
    For the record, coordinates were --   Newark, CA USA  37.554056,-122.03668

    I know this report is not particularly scientific, and I've never really
    reported PPAS format.  However, if nothing else,
    this has been one of the most SPECTACULAR flaring satellites I have ever
    seen in my observing career - definitely worth
    a look on ANY scheduled pass!
    I will try to get a good video of the pass tonight.  If successful, I will
    post a link to the video file.
