"An interplanetary shock wave hit Earth's magnetic field today at approximately 1645 UT (11:45 AM EST). This is the expected glancing blow from the CME produced by the X4.9-class solar flare of Feb. 25th. Polar geomagnetic storms and auroras are possible in the hours ahead".

Þessi mynd var á forsíðu Spaceweather.com í morgun.

Tryggvi Már Gunnarsson skrifar þar: "As I was driving from Reykjavik to north Iceland I saw this red halo on the sky. My first thought was: A volcano must be erupting!," says Gunnarsson. "Then, as the green colors appeared, I realized this was the aurora borealis. It was one of the most magnificent aurorashows I have ever seen."
