This time lapse shows what happened during four hours over Östersund here in Sweden, on Mars 17, when an CME (Coronal Mass Ejection) hit Earths magnetic field, resulting this stunning Aurora Borealis.    Have a look at the video…

Two days earlier, sunspot AR1692 had produced a M1-class solar flare that resulted in the CME that hit Earth.
