MAGNIFICENT ERUPTION: A filament of magnetism curling around the sun’s southeastern limb erupted on August 31st, producing a coronal mass ejection (CME), a C8-class solar flare, and one of the most beautiful movies ever recorded by NASA’s Solar Dynamics Observatory:
The explosion hurled a CME away from the sun traveling faster than 500 km/s (1.1 million mph). The cloud, shown here, is not heading directly toward Earth, but it could deliver a glancing blow to our planet’s magnetic field on or about September 3rd. This date is preliminary and may be changed in response to more data from coronagraphs on the Solar and Heliophysics Observatory (SOHO).
