QUADRANTID METEOR SHOWER: Earth is about to pass through a narrow stream of debris from shattered comet 2003 EH1, source of the annual Quadrantid meteor shower. Forecasters expect the shower to peak on Monday morning, Jan. 4th during the hours around 3 a.m. ET (0800 UT). The timing favors observers in North America who could see dozens of meteors per hour flowing from a radiant near the North Star. Visit http://spaceweather.com for more information.
