AN AURORA NAMED "STEVE": This weekend, a solar wind storm has sparked sightings of a mysterious filamentary aurora named "Steve" over the badlands of Alberta, Canada. Although the form has been seen for many years dancing among ordinary auroras, researchers do not fully understand what causes it. New clues recently emerged when a European Space Agency satellite flew directly through Steve.

The phenomenon is highlighted on today's edition of  Spaceweather.com.
