GEMINID METEOR SHOWER IS UNDERWAY: Earth is entering a stream of
gravelly debris from "rock comet" 3200 Phaethon, source of the annual
Geminid meteor shower. Although the shower's peak is not expected
until Dec. 13-14, observers are already seeing fireballs fly out of the
constellation Gemini as early-arriving meteoroids hit Earth's
atmosphere traveling ~35 km/s (78,000 mph).

observing tips may be found on today's edition of Spaceweather.com.
