In pictures: Aurora Borealis lights up sky above Scotland
Displays of the Aurora Borealis were visible from north and north east Scotland overnight.
Also known as the Northern Lights, the aurora appear as shimmering waves of light when atoms in the Earth's high-altitude atmosphere collide with energetic charged particles from the sun.
BBC Weather Watchers photographed the "lights" from Shetland, the Highlands and Moray.
