An overdue #CME struck #Earth's #magnetic #field on March 3rd. The impact sparked a #G2-class #geomagnetic #storm and bright #auroras around the Arctic Circle. Jan Eklind photographed the display from the window seat of an Airbus A20N at 35,000 feet:
"I was flying from Oslo to Kirkenes on Scandinavian Airlines when the CME struck," says Eklind. "Auroras spread across the sky with twilight in the distance and city lights below."

The CME was hurled into space on Feb. 28th when a magnetic filament connected to sunspot AR3592 erupted. It was not aimed directly at Earth, and forecasters were unsure if it would deliver even a glancing blow; however, the impact was stronger than expected.
