STRANGE AURORA-LIKE ARC SIGHTED OVER ALASKA: On Saturday night, something happened at the edge of space over Alaska. More than 200 km above Anchorage, a hot ribbon of ionized gas sliced through Earth's magnetosphere, creating a luminous arc that rivaled the Moon in brightness. Sanjana Greenhill witnessed the apparition:

"We noticed this perfect arc developing across the sky," says Greenhill. "It didn't seem like the aurora since it wasn't moving much. The arc got brighter and then faded and then got brighter again. And then it dawned on me, this is STEVE!"

STEVE is an aurora-like phenomenon that researchers are only beginning to understand. For many years, northern sky watchers reported the form occasionally dancing alongside auroras. It was widely called a "proton arc" until researchers pointed out that protons had nothing to do with it. So members of the Alberta Aurora Chasers group gave it a new name: "Steve" (since upgraded to STEVE, an acronym for 'Strong Thermal Emission Velocity Enhancement').

The first clues to the nature of STEVE came in 2016 when one of the European Space Agency's Swarm satellites encountered the phenomenon. "As the satellite flew straight though 'Steve,' the temperature jumped by 3000°C and the data revealed a 25 km-wide ribbon of gas flowing westwards at about 6 km/s (13,000 mph)," reports Eric Donovan from the University of Calgary.

Donovan and a team of colleagues led by Elizabeth MacDonald of NASA's Goddard Space Flight Center have just published a paper on STEVE.
