METEORS FROM HALLEY'S COMET: 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 tonight, Oct.
20-21, with as many as 20 meteors per hour. No matter where you live,
the best time to look is during the dark hours before sunrise on Wednesday the 21st. Visit Spaceweather.com for sky maps and more information.
MINOR STORM WARNING: High-latitude sky watchers should be alert for auroras after nightfall on Oct.21st and 22nd.
Earth is about to enter a fast-moving stream of solar wind, and this
could spark minor geomagnetic storms. Aurora alerts are available from http://spaceweathertext.com (text) and http://spaceweatherphone.com (voice).
