A small auroral display is in progress here in Duluth, Minn. with a series of faint rays now and again dappling the northern sky.¬†Might want to keep your eye on it. The Kp index, a good indicator of auroral activity, is currently at “5″ or minor storm level. A coronal mass ejection from the sun that blew by Earth this afternoon may be the reason for this uptick.

The auroral oval map indicates auroras potentially visible across northern Minn., Wis, Mich. and N. Dakota as of 11:30 p.m. CDT. To best see a northern lights display, find a site with a dark sky to the north and cross your fingers the lights continue. Good luck!
