Earth is passing through a stream of debris from Halley’s Comet, source of the annual Orionid meteor shower.
Forecasters expect the shower to peak on:
21st October, 2013
There may be approximately 20 meteors per hour. Bright moonlight will reduce visibility, however.
The best time to look is during the hours before local sunrise when the shower’s radiant in the constellation Orion is high in the sky. Check http://spaceweather.com for more information.
