There is a great Aurora Borealis (Northern Light) display happening right now in the sky above Nuuk, Greenland. It is nearing midnight there at the moment, and the sky is draped with the light display. Here is a link to the Nuuk airport webcam, which is showing the sky above the town. It is -6C at the moment. It looks best on a big screen TV, and be patient, the lights come and go as usual.
