Spiral
From 3 days ago:
This morning in arctic Norway, onlookers were stunned when a gigantic luminous spiral formed in the northern sky. Veteran observers accustomed to the appearance of Northern Lights say they have never seen anything like it. It was neither a meteor nor any known form of atmospheric optics. Rumors that the spiral was caused by the botched launch of a Russian rocket have not yet been confirmed.
