Caused by debris from Halley's Comet, the 2009 Orionid meteor shower peaks on Wednesday, Oct. 21st, and forecasters say it could be an unusually good show.
NASA -The 2009 Orionid Meteor Shower
METEORS FROM HALLEY'S COMET: Earth is entering a stream of dusty debris from Halley's Comet, and this is causing the annual Orionid meteor shower. If forecasters are correct, the shower will peak on Wednesday morning, Oct. 21st, with dozens of meteors per hour. The best time to look is during the dark hours before local dawn.
For the past three years, Orionid rates have been unusually high, with reports of 60 or more meteors per hour. Researchers believe this is a result of some very old and rich debris from Comet Halley drifting across Earth's orbit. Computer models of the debris suggest that it is still in the neighborhood, so the trend of "good Orionids" could continue in 2009. Visit http://spaceweather.com for photos and updates.
