Question
Where was Halley's comet observed?

Answer
Hi Terell,
When?
Tom

FOLLOW UP:
I first observed Halley in February 1986 from Erie, PA...then we took vacation to southern
Florida and saw it again from Sanibel Island just south of Fort Myers, in March of 1986.

Since then, I believe large telescopes have photographed it passing Saturn's orbit outbound,
down around 24th magnitude, but I haven't seen a recent picture of it.
Generally, all parts of the world get to see a bright comet, (except a polar region where it
is continuous daylight)  as they only move a degree or several degrees per 24 hours, so they are around quite a while...several weeks or months. (Unlike meteors that appear and are gone in
a flash).  Comets DO NOT streak across the sky, they move very leisurely across the sky, slowly
changing their position a little, from night to night...similar to our moon, but not even that
fast. (The moon moves about 12 degrees eastward every 24 hours in our sky.) Comets typically
move only one degree from night to night.
Clear Skies,
Tom
