Sightings of the aurora are likely along the northern horizon across Scotland, Northern Ireland and Northern England, according to experts at the Met Office s HQ in Exeter.
A solar storm could mean the Northern Lights will be seen from the UK on Wednesday evening, according to the Met Office.
The phenomenon, also known as the aurora borealis, should be visible under clear skies in Scotland, Northern Ireland, the Isle of Man and possibly even parts of Northern England, as well as other areas of the world near the North Pole.
The Northern Lights are created by disturbances in Earth s magnetosphere caused by a flow of particles from the Sun, and are usually concentrated around the Earth s magnetic poles.
Met Office said tonight s display stems from a coronal mass ejection (CME) – a massive expulsion of plasma from the Sun s corona (its outermost layer).
