Beautiful. I found this yesterday and set it as my lockscreen background, then realized I forgot to . After an hour and a half of searching "aurora," DDs for yesterday, and popular images in the past 24 hours, 3 days, week, and month (I COULD NOT figure out where I'd seen this, or the title, and for some reason the title didn't save with the image), I found it again. Worth it! I want a poster like nobody's business. Utterly beautiful, and the balance of color is just perfect.
Well, to me anyway. Auroras are like fluorite-- everybody has their favorite bit of awe.
