The story of the northern lights
Murmansk lies about 300 km north of the Arctic Circle and is the largest city in the world above it. Here, the solar wind meets Earth's magnetic field and makes the upper air glow green, pink and violet.
From early December to mid-January the sun does not rise at all during the polar night, so the dark sky lasts most of the day. The aurora is never guaranteed, but on clear, active nights it can fill the whole sky.
