On Nov. 23, 2012, at 8:54 a.m. EST, the sun erupted with an Earth-directed coronal mass ejection or CME. Experimental NASA research models, based on observations from the Solar Terrestrial Relations Observatory (STEREO) and the ESA/NASA mission the Solar and Heliospheric Observatory, show that the Nov. 23 CME left the sun at speeds of 375 miles per second, which is a slow to average speed for CMEs. This is the third Earth-directed CME since Nov. 20.
