POSSIBLE CME IMPACT: A CME launched by yesterday's M4.4-class solar flare might sideswipe Earth's magnetic field on Dec. 1-2, according to NOAA analysts. The glancing blow, if it occurs, is expected to cause no more than minor G1-class geomagnetic storms with auroras over high-northern latitudes. Scroll down for the full story.
