Earth-directed CME released by long duration solar flare

On Feb. 9, 2013 at 2:30 a.m. EST, the sun erupted with an Earth-directed coronal mass ejection or CME, associated with a long duration C2.4-class flare. Experimental NASA research models, based on observations from the Solar Terrestrial Relations Observatory and ESA/NASA’s Solar and Heliospheric Observatory, show that the CME left the sun at speeds of around 500 miles per second, which is a fairly typical speed for CMEs. Historically, CMEs at this speed are usually benign.
