A solar storm on its way to Earth could mean the Northern Lights might be seen from the UK tonight, forecasters have said.
The Met Office said the phenomenon, known as the aurora borealis, may be visible in Scotland.
Skies in Glasgow and Edinburgh are forecast to be cloudy this evening, but there could be breaks long enough to reveal the lights.
Further north, in the Scottish Highlands, or east, in Dundee and Aberdeen, the sky is likely to be clearer.
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.
The southward shift of the lights today is caused by an ejection of plasma, known as a Coronal Mass Ejection from the Sun, which followed a solar flare on Wednesday.
Bonnie Diamond, meteorologist at the Met Office, said: “A Coronal Mass Ejection has happened and the effects of that are expected to arrive later.
“This type of active geomagnetic storm means that there is the possibility of the aurora borealis, commonly known as the Northern Lights. Whether or not you will see the Northern Lights depends on where you are and what the weather is like. Scotland is where you’re most likely to see it.
“The clearest skies are further east in Aberdeenshire, where there are plenty of clear skies. Further north, you’re pretty likely to see something.”
