The Northern Lights, also known as aurora borealis, have been seen lighting up the night sky over Europe.
Time-lapse videos posted on social media show swirls of green, pink and scarlet moving across the sky.
They became visible after one of the strongest geomagnetic storms for years hit Earth, with the US National Oceanic and Atmospheric Administration (NOAA) issuing a rare solar storm warning.
The lights are caused by charged particles from the sun hitting gases in the Earth’s atmosphere.
