(meteorobs) Yorktown meteors
While doing some reading over the weekend, I came across a reference to a
shower of meteors that occurred on the evening of October 17, 1781, the
night a truce was declared at the end of the battle of Yorktown in the
American Revolution. I think these were probably the Orionids because using
the Orionids' solar longitude of 208 degrees yields a peak that year just
after 23 hours UT on the 17th, which would have been shortly after sunset in
Virginia (the Orionid radiant would have risen there about 10 PM). My
question: is 208 degrees the correct solar longitude to use? Has the solar
longitude of the Orionids' peak varied over the centuries, and if so, by how
much?
