    Dear List,
           I have something new which is perplexing and I would appreciate
    some feedback. Rob's IridFlar is generating a double flare by the same
    Iridium satellite in the space of a few seconds and I would appreciate
    some rationale behind this phenomenon.
           The first flare will start at 7:07:39 and last 4 seconds on Dec
    27/01 ... the second flare will start at 7:07:45 and last 6 seconds ...
    the respective magnitudes are -2.4 and -0.6 which should (?) be
    sufficiently bright for a photo at that time of the morning.
           In browing through my list of predictions, I see a couple of
    other opportunities about 1-2 minutes apart for the week after the above
    flare which suggests that something is at play.
