Skygazers in the UK could be treated to a show of the Northern Lights on Sunday night.
Scotland is expected to have clear skies overnight into Sunday, making it a great location to potentially witness the mesmerizing aurora borealis phenomenon. However, there is also a possibility of seeing this natural light display further south.
A map issued by the Met Office shows the chances of seeing the Northern Lights in the UK tonight.Â
The Met Office has indicated that there is a chance of aurora sightings over northern Scotland during the evening and overnight, with the possibility extending to most parts of Scotland as long as the skies remain clear.
‘There is perhaps a chance further south too, with long exposure photography.’
Met Office meteorologist Zoe Hutin said there is a ‘heightened chance’ of seeing them due to the low cloud coverage and clear skies in Scotland.
She said the movement of solar winds around the sun at this time is leading to the ‘enhanced possibility of a sighting’.
She added: ‘The further north you are, the more likely the chances are that you will be able to see them.
It is noted that auroras are more easily visible on cameras compared to the naked eye, resulting in clearer pictures due to the nature of the phenomenon’s light beams.

The sun has now entered its period of greatest activity, which means Britons could be seeing more colourful displays of the aurora borealis until the middle of the year.
The sun goes through an 11-year solar cycle, with periods of intense activity followed by a quiet phase.
During its active bursts, also known as solar maximum, the sun releases charged particles that travel through space at speeds of around one million miles per hour.
Some of the particles are captured by the Earth’s magnetic field and collide with oxygen and nitrogen atoms and molecules in the atmosphere.
These atoms and molecules then shed the energy they gained from the collision, emitting light at various wavelengths to create colourful displays in the night sky.
According to Nasa, oxygen emits either a greenish-yellow light – which is the most familiar colour of the aurora – or a red light, while nitrogen generally gives off a blue light.
The oxygen and nitrogen molecules also emit ultraviolet light, which can only be detected by special cameras on satellites.
The best way to catch the display is to find a dark place, away from light pollution such as street lights and ideally a cloud-free sky.Â

Some of the best aurora spots around the UKÂ are in areas of high elevation (closer to the magnetosphere) and away from cities that pollute the sky with artificial light.
The Northern Lights are caused by a ‘severe’ geomagnetic storm – a major disturbance of Earth’s magnetosphere, the area around Earth controlled by the planet’s magnetic field.
This disturbance is triggered when a violent stream of charged particles released from the sun’s outermost atmospheric layer is directed towards us.
‘There’s a reaction called nuclear fusion that occurs continuously deep within the sun’s core,’ explains Dr Amoré Elsje, an applied geomagnetic researcher at SANSA Space Science, in a new piece for The Conversation.
‘This generates massive amounts of energy.
‘Some of the energy is released as light (sunlight), some as radiation (solar flares), and some as charged particles.’
