The northern lights lit up UK skies on Halloween night, October 31, 2026.
Skywatchers in northern Scotland saw a bright green glow overhead.
Parts of Scotland and Northern Ireland saw colorful displays when the clouds cleared.
Fast solar wind streamed from a dark patch on the Sun, called a coronal hole.
The Met Office said there were no Earth-directed coronal mass ejections. The fast wind alone caused it.
The Sun is near the peak of its 11-year activity cycle, so UK auroras are more likely now.
A strong repeat tonight is unlikely for most of the UK. Far north Scotland has a small chance.
Find a dark spot away from street lights, with a clear view to the north.
Look between about 10 PM and 2 AM. Give your eyes 15 to 20 minutes to adjust.
Phone cameras often pick up colors that the naked eye cannot see.
