The Northern Lights have swept across UK skies because of an extreme Geomagnetic storm which could ‘bring widespread chaos’ and power outages.
The dazzling lights have been spotted by stargazers across the country, from the Highlands to Penzance.
While beautiful, the lights are caused by solar flares pulsing from the sun and can cause problems with electrics here on Earth, the Met Office has warned.
The geomagnetic storm making the lights surge southwards from the North Pole has been categorised as G5, the most extreme type.
This means there can be problems with power grids which ‘may experience complete collapse or blackouts’, while power transformers could be damaged, the Met Office said.
But it’s not just on Earth that these problems can cause severe issues, as spacecraft operations, like on the International Space Station (ISS) can be affected.
‘Drag may increase on low-Earth orbit satellites’ as well as ‘extensive surface charging’ which can damage instruments on board, which can lead to further service outages on the ground.

The geomagnetic storm can also affect radio frequencies and satellite navigation for days.
However, people online are watching on in wonder as the skies light up above their homes.
In some cases, the lights are not visible with the naked eye and can only be seen using a long exposure photograph, which many smartphones now carry as a feature.
To see the lights, head out to a dark place nearby and wait 15 minutes until your eyes adapt to the dark. Make sure to bring a camera.
Northern lights detection app AuroraWatchUK has issued a red alert for Northern Lights being visible across the country.
It has registered spikes of over 1,100nT (nanoteslas), very high readings for electromagnetism.
Meanwhile, the Met Office has said that this storm measures as a Kp index of nine, the highest value. Kp index is derived from the German Planetarische Kennziffer, meaning Planetary Index and a level of nine means extremely stormy which is disturbing the Earth’s magnetic field.

The height of the geomagnetic storm causing the aurora is yet to come at 2am tonight, the Met Office has predicted
The storm is forecast to last from 9pm tonight until 3am tomorrow morning, the Met Office said.
Social media has been flooded with people in awe of the lights in the sky.
One X user Suzzanne Evans wrote: ‘Just the most wonderful Northern lights here in Shropshire tonight’, alongside beautiful photos she said she took with her iPhone.
Further south, another user said: ‘Northern Lights in south Devon. Flipping gorgeous.’
Even further from the north pole, one user wrote: ‘Fantastic display of northern lights here in Penzance right now, even with some light pollution.’
Up north in Skye, Callum Montegomery said: ‘WOW. I’ve seen the Northern Lights in Skye before, but NEVER like that. Insane.
‘Completely visible to the naked eye even around streetlights.
‘Chuffed my mum finally seen them after complaining she’s never seen them after living in Skye her whole life!’
In a post on X, the Met Office said: ‘A fast moving coronal mass ejection (CME) means the northern lights may be visible overnight, and perhaps on Tuesday night too.
‘The arrival time of the CME is uncertain, but aurora sightings are possible in northern Britain and perhaps in southern areas depending on cloud cover.’
The height of the storm will likely be at around 2am next morning, according to an animation posted on X by the forecasters.
The lights will swirl mostly west of the UK and above Ireland and the Atlantic.
They still show up in the skies, however, in beautiful green and red illuminations as UK stargazers watch them.
When looking to see the lights outside, make sure to dress warmly, particularly in the north where temperatures are liable to be cooler.
The Met Office added: ‘We have received reports of the aurora visible as far south as Devon this evening.

Cloud cover is an important factor to consider when looking for the northern lights, and the Met Office has predicted there will be a lot of cloudy skies across the country though with pockets of clarity in the south west, midlands and Scottish highlands as well as in Ireland
‘If you have clear skies currently outside you may also be able to see the northern lights.’
Cloud cover is one of the main obstacles when trying to view aurora borealis and unfortunately a lot of the UK is covered in cloud currently.
However, there are some sweet spots, like in Devon and Cornwall, where many sightings have been reported as well as northern Scotland in the Highlands, where more have been spotted.
Much of Ireland is also unclouded too where many reports of the lights have festooned social media posts.
