In Rovaniemi, just south of the Arctic Circle, the heavens were green for much of the evening, occasionally exploding into rolling waves of color that lit up the night.
It is the eighth time in ten days that the Northern Lights have been witnessed in the area, with local stargazers ascribing the event to a high coronal hole on the surface of the sun, coupled with strong solar winds.
There are hopes that there will be more sightings of the Northern Lights across the UK this winter. To find out predicted activity, keep an eye on AuroraWatchUK.
