X Class Flare from the West Limb May Bring Aurora Sept 13

Northern Lights Now – Active Region 2673 may have rotated around the limb, but today it proved it wasn’t quite done influencing Earth’s magnetosphere. An X8.28 flare and associated CME launched from the region on Sunday October 10. The CME is so wide that NASA models are suggesting Earth will get a glancing blow on Sept 13.

The flare released energetic particles that saturated the LASCO imagery on SOHO. In this loop, see the CME launching, then a “blizzard” as the sensors pick up the high energy particles associated with the eruption.
