1997 Leonids from orbit
Some background on the Leonids:

NASA's Leonid site. Next storm is predicted to peak in Nov. 19, 2002.
I saw one of these streaking by last week @ about 10pm ET. A good sized one at that. It had a long light yellow tail and a very bright white elongated 'head'.
(stopped me cold). Visually tracing it's path, it did come from Perseus.
