This was the most intense aurora I’ve ever seen. With a jaw-dropping corona above, dancing curtains, rotating vortices and lightning-like events extending all the way to each horizon, nearly every square inch of the sky – for a full 360 degrees – was filled with color. This was taken about 150 miles north of the arctic circle, during a geomagnetic storm that registered a Kp=6. Moments like this quickly make up for weeks in the unbearable cold.

For those interested, I've written an article on photographing the aurora HERE
