For the Aminus3 prompt Nightfall.

I took this on our amazing trip to Norway. We were on a cruise to Tromso in November last year in the hope of seeing the Northern Lights. We took a coach trip into the countryside to a dark sky area the night we docked and as we were traveling the coach driver stopped the bus and suggested we get out and look. We were treated to this incredible sight, and to add to it one of the nearby farms must have had dogs, because when the lights began to show more vivid the dogs began to howl like you would expect a pack of wolves. This really was one of the most amazing things I've ever witnessed and for my wife and I a bucket list event ticked off as well as something we will never forget.
