A Michigan-based heaven photographer got an unexpected treat last dark when an aurora-like ribbon of glowing stripes paraded just above his head.
The ribbon was caused by the phenomenon known as
(for Strong Thermal Emission Velocity Enhancement), a rare type of atmospheric glow like to
polar lights, which tin exist triggered when a stream of solar plasma interacts with
STEVE, commencement described in 2016 by skywatchers in Canada, can occur further away from the poles than an aurora and is far less common.

For Isaac Diener, an atmospheric photographer based on the Keweenaw Peninsula in Upper Michigan, the STEVE on Mon (Sept. 5), was only the 2d he has seen so clearly in the vii years since he started observing auroras.
“You lot tin can’t predict when it’s gonna happen,” Diener told Space.com in an electronic mail. “Information technology appears out of nowhere.”
Diener, who took up photography to help distract him from a chronic pain status, had a prolific dark on Monday when conventional auroras also showed upward above Eagle Harbor on the Keweenaw Peninsula in what was the
third night of colorful aurora displays
in a row.
Diener said he uses the same equipment and settings for his shots of STEVE as he uses to have his aurora images.
“I employ a Fujifilm XT-3. And the lens I employ is a 16mm lens,” Diener wrote. “Settings I used on those STEVE pics are Aperture 1.4, 12 seconds, ISO 800.”
Aurora sightings on previous nights came from several regions in Canada and the northern U.S. including Yellowstone National Park, according to
The current aurora displays accept been fed by a
coronal mass ejection, a flare-up of charged particles from the region of the sun’s
known equally the corona, released by the star on Friday (Sept. 2). The interaction of the material from the sunday with Earth’s magnetic field triggered a moderate geomagnetic storm, which was further bolstered by an increased flow of solar wind from an opening in the sun’s magnetic field.
