    Hi All,
    With the next full moon coming up in a little over a
    week, I thought I'd let everyone know (that doesn't
    already) that Mike McCants has posted the latest version
    of my IRIDFLAR program (version 2.0) at:
    This version gives you the choice of searching for solar
    Iridium flares OR lunar flares.  You'll definitely need
    binoculars or a telescope for the latter since the peak
    magnitude never gets brighter than about +7.
    The program does take the lunar phase into consideration
    when calculating the magnitude, and only reports lunar
    flares that occur when the satellite is also NOT sunlit.
    I've read that USSPACECOM is changing the names of some
    of the old tumbling Iridiums like 11, 20, 21, 24, etc.
    to 911, 920, 921, and so on, and that the replacements
    that were named 11A, 20A, and so forth are being changed
    to 11, 20, ...  While IRIDFLAR will balk at these new
    names, it should still produce correct predictions.  I
    hope to put together an update later this week that takes
    this change into consideration.
    Best wishes,
    P.S.  This version requires a coprocessor.  If your computer
    does not have one, contact me and I'll compile a version
    for you that works without a coprocessor.
