Mathisen is an editor and cameraman for Norwegian Broadcasting, and clearly has an excellent eye for the sky. He has another aurora video he shot in 2010.
This is exactly what I needed as temperatures here push 40°C. It’s nice to know that while we’re sizzling here, the atmosphere is sizzling with cold light elsewhere.
