For the 2nd night in a row, there was an active display of the northern lights in Abisko, Sweden. Starting off as a dull glow in the north after sunset, it quickly exploded with bright green spiral swirls filling the entire sky. Here above the Arctic Circle the aurora is ever present, encircling the Earth's poles in a zone called the auroral oval. Even during solar minimum when solar activity is quiet, the northern lights are visible on almost any clear night. And Abisko sees more clear nights than surrounding areas because the mountains to the west create a rain shadow effect. Visible beyond the forest of short birch trees, is Torneträsk, Sweden's 6th largest, and 2nd deepest lake.
