Northern Lights may be visible on Monday night – Met Office

The Northern Lights may illuminate the sky over parts of Wales on Monday night and early Tuesday morning, the Met Office has said.

The lights, also known as aurora borealis, are most likely to be visible in areas of clear sky including in Scotland and Northern Ireland as well as northern parts of Wales and England, the forecaster said.

There may also be a “chance of sightings further south”, the Met Office added in a post on X.

For those hoping to spot the aurora, meteorologists have advised staying away from areas with light pollution and using a long exposure camera as they are better able to adapt to different wavelengths than the naked eye.

Daylight hours clash

Met Office spokesperson Andrea Bishop said: “Aurora activity is expected to peak on Monday following the forecast arrival of a coronal mass ejection.

“However, for the UK, this period is expected to coincide with daylight hours.

“Lingering effects are still likely to persist into Monday night and early Tuesday morning though, meaning that aurora is likely to be visible where skies are clear from Scotland and Northern Ireland, as well as parts of England and Wales, mainly in the north.

“It’s not possible to predict how far south the coronal mass ejection may be seen or pick out cities, but in terms of visibility overnight, there are generally clear skies for most tonight, however, it will be cloudier across the Northern Isles and western Scotland, with patchy rain and drizzle as well as cloudier skies in Northern Ireland.

“There’s also patchy cloud for some in the south east and East Anglia.”

Remote, open areas with views of the northern horizon are best for sightings, with the lights unlikely to be visible until it gets very dark.

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.

In the northern hemisphere, most of this activity takes place within a band known as the aurora oval, covering latitudes between 60 and 75 degrees.

When activity is strong, this expands to cover a greater area – which explains why displays can be occasionally seen as far south as the UK.
