Earth-directed X-class flare

An active region just about squarely facing Earth erupted with an X 1.6 flare (largest class) as well as a coronal mass ejection on Sept. 10, 2014. The flare lasted longer than usual and sent out a burst of radiation into space. The movie shows the bright, flickering flare and the ensuing coils of magnetic loops over a period of about five hours. A darker wave of material was also propelled across part of the Sun's surface. Images were taken in a wavelength of extreme ultraviolet light. Credit: NASA/Solar Dynamics Observatory NASA image use policy.
