    The latest data I processed for this object are from Sep.2002, so my
    predictions were about 1.5 h off (I have not yet added Ed's
    Still, it seems to me that it would flash 6 min earlier (same RA?) per
    20 d W of Ed, flashes 15 min earlier than Ed's, at +0:03 in RA.
    For Don at 39N, 77W, flashes 20 min after Ed's, at +0:12 in RA.
    Don might also see the "backside" of the flashes, some 3.5 h earlier, if
    the cone angle is 78 degrees as calculated then.
