FROM HALLEY'S COMET: Earth has entered a stream of debris from Halley's
Comet, source of the annual Orionid meteor shower. Forecasters expect
the shower to peak during the night of Oct. 20-21 with as many as 10-20
meteors per hour. Glare from tonight's gibbous Moon will mute the
display, but not completely eliminate it as NASA cameras are observing
some Orionid fireballs bright enough to be seen in the moonlight.
