Amazing auroras light up the skies over Michigan in a stunning new time-lapse video.
Shawn Malone collected hours of footage to create the nearly seven-minute video, which represents a year of travel and shooting in northern Michigan. Malone followed the northern lights in the upper part of the state, usually taking at least three hours to get all of the shots she needed on any given night.
"There are a few really rare combinations like aurora and lightning and aurora and fogbow kind of thing, or the big bursts in the auroral substorms that are all [high resolution] raw files," Malone wrote in an email to SPACE.com. [Watch the Amazing Aurora Video]
The video also captures a few celestial surprises. Various planets, nebulas, the Milky Way, meteor showers and even Comet Pan-STARRS can all be spotted in the short film.
"In the climax of the video, the very bright aurora scenes, those are all very special," Malone said. "At our latitude of 46.5 degrees that kind of auroral activity doesn't occur nearly as frequent as say, latitudes around the Arctic Circle, I can count them on one hand in the past few years. In fact there were YEARS I went without seeing the aurora at all here in northern Michigan a few years back when there were absolutely no sunspots happening on the sun."
Auroras are created when charged particles from the sun enter Earth's upper atmosphere and strike neutral particles, creating the distinctive red and green glows of the northern lights. The cosmic light show is usually confined to the planet's higher latitudes because Earth's magnetic field tends to funnel these particles toward the poles.
Malone's part of Michigan might be seeing more auroras in the near future. The sunspot AR1748 has been extremely active lately, firing off four extremely powerful solar flares over the course of 48 hours from Sunday to Tuesday (May 12 to 14).
The first three of these X-class flares was unleased while AR1748 was facing away from Earth. But the sunspot is rotating toward Earth at present, and a huge eruption of solar plasma called a coronal mass ejection (CME) associated with the last flare, which occurred late Tuesday night, is slated to give Earth a glancing blow Friday (May 17).
CMEs that hit Earth can supercharge the northern lights, delighting skywatchers. But powerful ones can have negative consequences as well, spawning geomagnetic storms that temporarily disrupt power grids, GPS navigation and satellite communications.
