"The Leonid meteor shower will be making an appearance on Nov 17, 2003, and it might be an impressive show. These meteors are the minute dust trails of Comet Tempel-Tuttle which flash in the sky as they strike Earth's upper atmosphere. In past years the shower has been impressive- sometimes 1,000's of meteors per hour have been seen(2001). Astronomers are unsure how intense the shower will be this year, it could be anywhere from 2 per hour to anything up to 200-300 per hour. Best views will be from Europe, but the rest of the world will still get a show if you watch the skies after local midnight."
