Beautiful Aurora Video by astrofotografen

You should really check out this awesome link. It's a virtual reality of the auroras that 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. The pictures were taken in Östersund, Sweden between 19:20 and 23:35 UT.
