Flare Well AR2673

Almost out of view from our fair planet , rotating around the Sun's western edge giant active region AR2673 lashed out with another intense solar flare followed by a large coronal mass ejection on September 10. The flare itself is seen here at the right in an extreme ultraviolet image from the sun-staring Solar Dynamics Observatory. This intense flare was the fourth X-class flare from AR2673 this month . The active region's most recent associated coronal mass ejection collided with Earth's magnetosphere 2 days later . Say farewell to the mighty AR2673, for now. For the next two weeks, the powerful sunspot group will be on the Sun's far side .Mission: Farewell Cassini
