People have been sharing pictures on social media
People have taken to social media to share pictures of the Northern Lights, which were seen lighting up the night sky across parts of Northamptonshire.
Also known as aurora borealis, they've been across the UK, even reaching as far as Ireland.
Experts said the visibility of the Northern Lights was increased on Friday because of an "extreme" geomagnetic storm, which saw the sky light up in pink and green.
Met Office spokesman Stephen Dixon said on Friday there was a good chance for the Northern Lights to be seen.
He said: "Although the shorter nights will limit the visibility window, there's a good chance to see the aurora, particularly on Friday night and especially in Scotland, Ireland and parts of northern England and Wales.
"There could even be visibility further south if you have the right equipment.
"Those conditions could continue on Saturday night but we still have to work out some details on where exactly that will be."
