The severe geomagnetic storm late yesterday produced rare auroras seen as far south as Georgia and Arkansas last night.

This photo was taken by Tyler Penland, an astronomer and weather observer in N. Georgia:

The display was more spectacular farther north, of course. Here’s a photo from Billings, MT:

And in Denoir Valley, WY, the colors were amazing, with no FM radio station reception during the peak in the display around midnight:

In Marquette, MI, Shawn Malone (LakeSuperiorPhoto.com) captured this view looking right up through the ribbons of light:

The same solar storm brought rare auroras to Australia as well:
