    We just saw Coriolis pass near gamma Cyg but only saw 2 or 3 flashes,
    of magnitude ~ +5 (i.e. slightly dimmer than 34 Cyg's magnitude of 4.77).
    Using 10x50 binoculars, I was only able to see it at its maxima (but
    that part of my sky is fairly badly light-polluted so more useful
    data awaits observations from darker skies).
    The flashes were approximately two seconds apart, and were seen at
    2003 Jan 21 / 23:16.1 UTC at an alt/az of 26deg/302deg. At a range of
    995 miles and an astronomical phase of 120 deg, the peak of the few
    flashes we saw corresponded to a quicksat intrinsic magnitude of +2.3
    and a SkyMap standard magnitude of +2.8 .
    Tomorrow we have a slightly higher pass and perhaps we'll be able to
    see it again.
    Clear and dark skies!
