SCOTS have a “decent chance” of seeing the Northern Lights on Thursday night, the Met Office has said.
The weather service said sightings of the lights, also known as aurora borealis, were likely in Scotland and Northern Ireland, and possible in the north of England and the Midlands.
The Met Office said relatively clear skies were forecast for much of the UK, creating a “decent chance of visibility” on Thursday night and into the early hours of Friday.
“The further north you are, the more likely you are to get good visibility,” Met Office spokesman Stephen Dixon said.
The exception to this is in parts of the west of Scotland, where the northern lights may be obscured by showers and clouds.
Dixon added that further residual viewings could be possible over the weekend, however, this is likely to be confined to Scotland.
He said there had been “more space weather events in recent months”, including the Northern Lights, because the sun was nearing the peak of its solar cycle.
Dixon said: “When it does reach Earth, there are likely aurora sightings in Scotland and Northern Ireland, with a chance of some sightings in the north of England and slightly further south.
How do the Northern Lights work?
Aurora displays occur when charged particles collide with gases in the Earth’s atmosphere around the magnetic poles.
As they collide, light is emitted at various wavelengths, creating colourful displays in the sky.
The auroras on Earth, which are most commonly seen over high polar latitudes but can often spread south to be visible over parts of the UK, are chiefly influenced by geomagnetic storms which originate from activity on the sun.
The sun works on a cycle of around 11 years called the solar cycle – with peak sunspot activity on the surface of the sun referred to as solar maximum.
Sunspots give the potential for Earth-directed releases of large bursts of energy, called coronal mass ejections, which can lead to aurora visibility.
Dixon said: “We’re near the peak of that solar cycle so there have been more space weather events in recent months.
“International prediction centres, including the Met Office Space Weather Operations Centre, are expecting solar maximum to be later this year or early next year.”
He added that it would still be possible to see the Northern Lights in the UK once the sun passes the peak of the solar cycle.
Dixon said: “As we move through the next few years, we expect a gradual decline.
“But that doesn’t mean we won’t see further space weather events, where you could see auroras across the UK.”
