  	COMET HALLEY TIMETABLE (Thanks to: Orion Telescope Center)

OCT82	First observatory photo at one billion miles from earth.

NOV84	First observatory visual observation.

AUG85	First expected sighting through larger amateur scopes at new moon.

SEP85	Well placed for moderately large amateur scopes.

OCT85	Within range of smaller scopes and large binoculars.  Tail partially
	visible through larger amateur scopes.

NOV85	Visible all night with scopes and binoculars.  First likely appearance
	of tail with smaller instruments.

DEC85	First expected naked-eye observations.  Wide field scopes should show
	tail about 4X the diameter of the full moon.

JAN86	Comet disappears behind sun toward end of month.

FEB86	Tail reappears above morning horizon towards end of month.

MAR86	Bright head and long tail rises above horizon.

APR86	Best month for naked-eye viewing.  Comet will be low in the south for
	viewers in the northern hemisphere.  Pick a remote, dark location for
	viewing.

MAY86	Head becomes largest as tail shrinks to narrow line. Invisible to naked-
	eye viewers by end of month.

AUG86	Visible only with large amateur instruments.

Add seventy-six years and try again. |-)
