Another great afternoon in Abisko!! When I saw that the proton density was over 60 per square cm I grabbed my camera and ran as fast as I could to one of my favorite photos spots. Soon after I arrived the lights began. It was a great showing with dancing auroras for several hours. Thanks again to spaceweather.com for the heads up!! Shot with a Nikon D7000, Tokina 11-16 2.8, 1600 ISO, 6-8 second exposure.
