Between swiftly-moving blankets of cloud we’ve been treated to some superb aurora borealis this evening. I just got back in after taking a few pictures and enjoying the show to share the news. The Kp index, a reliable indicator of magnetic and associated aurora activity high in Earth’s atmosphere, is up to 6 or minor storm level.
From Duluth, Minn. we’ve got rays stretching far up the northern sky and bright, shorter rayed arcs lower down. Nice mix of pale pinks and greens. Here are a few photos. Find a place with a good view to the north, grab your coat and go. Oh, be sure to let us know what you see. Thanks!
PS. I didn’t see any Draconid meteors in the half hour I was out. Not giving up yet though. Time to head out for more solar rays!
UPDATE 11 p.m. — The display has evolved into big, amorphous patches of light that swell almost to bursting before suddenly fading away … and re-appearing a moment later. Curious to watch and very hard to photograph. I tried anyway and used short 5 second exposures for minimal motion blur.
Waves are also starting to ripple through the patches, a phase called flaming.
