摘要

We are all familiar with 'aurora' - aurora borealis in the northern horizon and aurora australis in the southern horizon - bright waves of mostly green (sometimes red or blue) light observed in high latitude sky at night. But several years ago, citizen scientists from New Zealand, Canada, the U.S.A. and the U.K. started reporting in social media the appearance of an unusual sight in the night sky: an extremely narrow ribbon of dazzling purple and white colours (that do not diffuse) travelling across the sky for about an hour at a time and visible at lower latitudes than where a classical aurora is observed, mostly in the spring and the fall. The citizen scientists did not have a scientific explanation for this phenomenon. But one of them from Alberta, Canada playfully named this subauroral spectacle 'Steve', a joke alluding to a mysterious hedge in the 2006 children's film Over the Hedge, which frightens some woodland creatures when they come upon it suddenly in their environment.
