Now updated with more images and video! Reports of spectacular aurora are coming in! A CME hit Earth’s magnetic field on Oct. 24, 2011 at about 1800 UT (02:00 pm EDT), spawning some stunning red sky shows. All-red aurorae are fairly rare, and are produced by high-altitude oxygen, at heights of up to 200 miles, being excited by collisions from charged particles released from the Sun.
Above is the view by Randy Halverson, of Dakotalapse.com fame, whose work we feature often on UT. He’s not in his usual location of South Dakota, but is in Wisconsin, along with his son River Halverson. Randy said via Twitter that the brightest aurora he saw was about 8:25 or so local time (CDT).

John Chumack is another astrophotographer whose work we feature often. Here’s one of his shots of the Aurora Borealis on 10-24-2011 from John Bryan State Park, near Yellow Springs, Ohio. “30 second exposure, ISO 400, 8mm fisheye lens,” John says. See more from him on his website, Galactic Images (and he uploads frequently to our Flickr group, too!)
Joe Lloyd from northern Ohio took this image from his driveway!

This is an image from the AuroraMax all-sky camera located in Yellowknife, Ontario Canada. If you can’t see aurora where you are located, you can always check out the live video every night from AuroraMax,
Here’s the event on the Sun that started it all, the coronal mass ejection (CME) that caused aurora. The SOlar Heliospheric Observatory (SOHO) captured this “coronograph” – so-called because the images block the Sun, and only show the Sun’s atmosphere, or corona.
