Have You Seen Steve?

Via David Reneke:

NASA is searching for Steve (and they want your help).

According to Liz MacDonald with NASA’s Goddard Space Flight Center, “STEVE is a very narrow purple arc and sometimes it has these little green features that go along with it as well that are kind of like waving fingers or a picket fence.”

STEVE was first noticed by citizen scientists who were observing the aurora and saw this unusual purple swirl showing up in low latitudes, farther south than the aurora typically appears. When asked, NASA scientists didn’t know what it was.
