Amateur Skywatchers Spot New Atmospheric Phenomenon

Amateur Skywatchers Spot New Atmospheric Phenomenon

Its name is Steve, and it’s more common than you might think

Facebook is a place to share dramas and dog pictures, hit “like” and watch weird events unfold live. But for a group of amateur skywatchers, the social network is also a place to share information about what people spy in the sky. And thanks to a group of Canadian aurora enthusiasts, an entirely new type of atmospheric phenomenon has been documented.

It’s called Steve, and its origins are a bit more exciting than its straightforward name would suggest. The Alberta Aurora Chasers Facebook group first spotted the phenomenon last year, reports Gizmodo’s George Dvorsky, and has been collecting photos of Steve sightings. The name Steve reflects their confusion about the phenomenon’s origins, Dvorsky writes, and reminded someone of the movie Over the Hedge “in which a character arbitrarily conjures up the name Steve to describe an object he’s not sure about.”

As described in the Wikipedia Plasma article:

"It can simply be considered as a gaseous mixture of negatively charged electrons and highly charged positive ions, being created by heating a gas or by subjecting gas to a strong electromagnetic field."

"Even in a "cold" plasma, the electron temperature is still typically several thousand degrees Celsius."

Pretty Cool atmospheric observation.
