Here's Strand on his lovely compilation:
This video shows what happened on March 17 when an CME (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 shows what happened during four hours over Östersund here in Sweden, between 19:20 and 23:35 UT.
The photo of the Sun is a hydrogen alpha mosaic I've made from 10 images that was captured on March 16. Total of 10 Gb data. So all in all this movie contains over 40Gb of data that I've been processing over the last five days. Hope you enjoy it.
We've seen quite a few aurora shots, but this one is truly unique. It's all-sky, folks! Short of going north yourself, there's no better way to view this incredible natural phenomena.
