    No. You need to track along the edge of the shadow, which for the spring
    season, will range from eastern Hydra to western Virgo, changing 1 degree
    each night. Follow that shadow across the sky from east to west during the
    night. The sats located all along the belt will flare up (I think Ed
    described it once as a string of pearls) because the sats are stationary,
    and the shadow is moving.
    Stay about 5 degrees either side of the shadow, also - the sats are
    brightest just before they enter the shadow (except for the ones Ed, Kevin,
    and Bjorn  mentioned off about 45-60 degrees).
    I wish the geosat flare area was in Orion - how convenient. But it will be
    about 6000 years before precession brings it there. And there may not be any
    geosats by then. But I'll bet there'll still be Feng-Yun debris :O)
