Spectacular Northern Lights over UK

Dunstanburgh Castle near Alnwick in Northumberland made a dramatic setting for Phil Pounder's shot of pink shades of Aurora Borealis.

 There have been spectacular displays of the Aurora Borealis - better known as the Northern Lights - across parts of the UK overnight. The colourful phenomenon was visible in Scotland and Northern Ireland, but was also spotted as far south as Anglesey and Oxfordshire. Aurora Borealis occurs when electrically-charged particles from the Sun enter the Earth's atmosphere. Many people took to social media to share photographs of the dramatic show.
