Northern Lights UK Alert — 5 June 2026: G3 Strong Storm Active Now, Aurora Possible Across Much of the UK Tonight
A G3 Strong Geomagnetic Storm is now active as three coronal mass ejections from the Sun merge into a single 'cannibal CME' and strike Earth. Scotland, Northern Ireland, and northern England have an excellent chance of aurora tonight — and with Kp forecast at 6–7, even Wales and parts of the Midlands could see the lights. Check your skies after midnight.
