"After spending many hours waiting in the cold forest of Ruka, Finland, at -36 degrees Celsius, and without any visible aurora activity, we decided to walk back to our cars," Jenssen wrote.
"On the trail down, I saw something on my left side and told my friend to stop and wait. Suddenly, the aurora started to 'dance,' and all I had to do was to jump in the snow, get my camera ready, and shoot! There was no planning or time to focus on composition. After five minutes, the Northern Lights disappeared, but it was a night with a happy ending."
