Watch four hours of Aurora Borealis compressed into three stunning minutes
Photographer Göran Strand used 2464 raw images taken with his all-sky camera to create this gorgeous time-lapse video. The swirling crystal ball images show the view from Östersund, Sweden, when a when a Coronal Mass Ejection hit Earth’s magnetic field.
Sunspot AR1692 produced a M1-class solar flare and on March 17th, the resulting CME hit our magnetic field, creating this marvelous light show. Strand captured the aurora between 19:20 and 23:35 UT so that he could share the view with the rest of us.
