Emma PaliczkaPowerful displays of the Northern Lights were visible from across Scotland overnight.
Clear night skies provided the best opportunities for seeing the space weather, also known as aurora borealis.
The lights are caused by charged particles from the sun hitting gases in the Earth’s atmosphere, and overnight were visible as far south as Buckinghamshire and London.
The colours are picked up by cameras, including those fitted to mobile phones.

Forecasters said the chances of seeing the aurora would gradually ease through Friday, and would become increasingly confined to northern latitudes by Sunday.
UK sky-watchers on Monday night were treated to the rare phenomenon known as Steve, a relatively new scientific discovery that looks like the aurora.
Its name means Strong Thermal Emission Velocity Enhancement.

G4 is the second highest rating on the scale BGS uses and it signifies a severe storm.
Dark autumn and winter nights offer the best chance of seeing displays – if skies are clear – and there are websites, apps and social media groups providing forecasts and alerts for when they might occur.
