Chance again tonight April 20-21 for northern lights

Very nice aurora north of Duluth about 10 p.m. Sunday night. The rays were intensely colorful in the camera but much paler to the eye. Credit: Bob King

There’s been some action on the aurora scene today. A coronal mass ejection from the sun blew by Earth this afternoon and sparked auroras over northern Scandinavia and other locations in northern Europe where it was dark at the time. There’s continues to be a fair chance for minor auroras over the northern U.S. tonight (Sun. April 20-21), so you may want to be on the lookout. Check the Ovation Aurora site to see the extent of the aurora in near real time.

UPDATE 1 a.m. April 21 — The northern lights made a decent showing over northern Minnesota between the end of twilight around 9:30 p.m. until about 10:45 p.m. Sunday night. Lots of slow-moving, “lazy” rays to 50 degrees across the north. Extremely colorful in the camera but pale pink-purple to the naked eye at best. Hope you got to see the show.

Occasional rays formed that glowed for many seconds at a time before fading away appeared in the northern sky. Credit: Bob King
