This winter I decided to go way up north into the arctic circle to see the northern lights. The choice destination was Tromsø, Norway as it is far enough into the arctic circle but because of the gulf stream, it stays relatively warm. The coldest temperature when I was there was -12 degrees C. Since we only had 2.5 hours of daylight each day, I took lots of photos in low light. In this photo, the lights of Tromsø shine at twilight.
