METEORS FROM HALLEY'S COMET: Earth is entering a
stream of debris from Halley's Comet, source of the annual eta Aquariid
meteor shower. Although the shower does not peak until later this week,
a radar in Canada is already detecting strong echoes from the debris
zone. This bodes well for sky watchers who could see 30 or more meteors
per hour in the nights ahead. Visit http://spaceweather.com for updates and observing tips.
