    I don't know if anyone else has tried it, but last Sunday night I was able
    to observe all of the satellites in one Iridium plane.  I started with
    Iridium 22, Plane 2, Slot 01, in CMi at about 7:00 pm CST.  The sequence
    continued with 20 (spare), 24 (failed), 23 (Slot 02), 76 (Slot 03), 25 (Slot
    04), the flare from 25, 45 (Slot 05), 46 (Slot 06), 47 (Slot 07), 69
    (failed), 11 (Slot 08), 71 (failed), 49 (Slot 09), 26 (Slot 10) and finally
    03 (Slot 11).  I then observed 22, 20 and 24 for a second time each, all of
    them in Peg, ending at about 9:00 pm CST.  It was a fantastic demonstration
    of the rotation of the earth as each satellite was slightly farther to the
    west than its predecessor.  The final observation of Iridium 24 was also
    really neat because it flared repeatedly at irregular intervals because of
    its tumbling and relative orientation in the sky.  Now I can see why all of
    you time satellite flashes!  I'm not familiar or accurate enough yet to
    report the timings, but I'll try to do so in the future.
    Clear Skies,
