Auroral Corona over Norway : Higher than the highest mountain lies the realm of the aurora. Auroras rarely reach below 60 kilometers, and can range up to 1000 kilometers. Aurora light results from energetic electrons and protons striking atoms and molecules in the Earths atmosphere. Somewhat uncommon, an auroral corona appears as a center point for a surrounding display and may occur when an aurora develops directly overhead, or when auroral rays are pointed nearly toward the observer. This picturesque but brief green and purple aurora exhibition occurred last month high above Kvalya, Troms, Norway. The Sessyfjorden fjord runs through the foreground, while numerous stars are visible far in the distance. via NASA

Gorgeous! Norway seems like the best place to see the lights. We spent 3 weeks in Alaska a few years ago, but didn’t get to see any. There is a service, SoftServe, that will notify you when the lights are active in your area. Living in a major city, we have too much light pollution to ever see them, despite being far enough North.
