Finals Week Aurora Borealis

It’s finals week here at UAF and that means no sleep because you’re studying… or, because the aurora is out! Last night I simultaneously watched the aurora “oval” (i.e. the prediction of aurora visibility as provided by NOAA Space Weather) on my screen and studied for my evolution exam on Tuesday. When the aurora perked up overhead  at 10:30 PM I abandoned my books, and headed outdoors. For the sake of my education, I decided to stay close to home last night and shoot over the UAF Sustainable Village so that I wouldn’t stay out too late. It was a stunning night to be out!

I am continuing to improve on my timelapsing technique. Last night these images were shot at 1sec with no buffer for card write in the middle. In the past I have left 2 seconds for card write. Often in those two seconds the aurora changes so much that a small gap has been created. You’ll notice without that gap, that the Aurora is silky smooth! Although this isn’t real-time, at 1 second intervals it’s getting pretty close! The 1 second exposure captured the vertical banding of the high aurora well.

Here is the timelapse from the night:

And, here’s the imagery.

The Green flame morphs a little bit over the Sustainable Village. A beautiful night out!

A Facebook Follower described this as a 'green flame' to me this morning. I think that's a pretty apt description!

In all of these images I have desaturated the foreground to remove light pollution. I think the effect is pretty nifty!
