Above the arctic circle, Aurora Borealis is not too uncommon thing to see. I lived in Muonio (in Finnish Lapland), and the northern lights in Lapland are something I will never forget.
Finnish name for this phenomenon is "Revontuli" (fox's fire). A children's comics series Minttu had an illustration for this that I will remember forever: A fox sitting on top of fjeld next to a fire, with the flames coloring the sky.
