A long duration M-class flare began erupting on the sun at 8:42 AM ET on Thursday, January 19. The flare is shown in the above movie from the Solar Dynamics Observatory in a combination of light wavelengths. An earth-directed coronal mass ejection was associated with the solar flare. NASA’s Space Weather Services estimates that it is traveling at over 630 miles per second and will reach Earth some time on Saturday, January 21, when strong geomagnetic storms are possible and viewers can be on the look out for increased aurora.
