This video taken by Göran Strand from Östersund, Sweden shows what happened on March 17, 2013 when a Coronal Mass Ejection hit Earth's magnetic field. Two days earlier, sunspot AR1692 had produced a M1-class solar flare that resulted in the CME that hit Earth.

This time lapse from an all-sky camera captures the magnificent sky show between 19:20 and 23:35 UT on the 17th.

Strand said via email that this time lapse consists of 2464 raw images for a total data amount of 30Gb from the 17th. The stunning photo of the Sun is a hydrogen alpha mosaic he made from 10 images that was captured on March 16.

Beautiful!
