Berkeley News: When is an aurora not an aurora?

Phenomena called “Steve” and “picket fence” are masquerading as auroras, graduate student argues. Claire Gasque, a University of California, Berkeley, graduate student in physics, has now proposed a physical explanation for these phenomena that is totally different from the processes responsible for the well-known auroras. She has teamed up with researchers at the campus’s Space Sciences Laboratory (SSL) to propose that NASA launch a rocket into the heart of the aurora to find out if she’s correct.
