EARLY GEMINIDS: Earth is entering a stream of debris from “rock comet” 3200 Phaethon, source of the annual Geminid meteor shower. The shower is not expected to peak until Dec. 14th, but NASA meteor cameras are detecting Geminid fireballs over the USA two weeks early. Visit http://spaceweather.com for images and updates.
AURORA WATCH: A high-speed solar wind stream is buffeting Earth’s magnetic field on Dec. 1-2. High-latitude sky watchers, especially those around the Arctic Circle, should be alert for auroras in the nights ahead. Geomagnetic storm alerts are available from http://spaceweathertext.com (text) and http://spaceweatherphone.com (voice).
