Brits are due to be mesmerised by another round of Northern Lights sightings for a second night in a row, but cloudy weather could spoil the beautiful sight for millions.

The night sky was illuminated yesterday from the Scottish Highlands all the way to Penzance in Cornwall after a G5 geomagnetic storm hit Earth – the highest level.

Tonight, the Met Office predicts a G3 storm, meaning it is likely that yet more aurora borealis will be visible from the UK.

However, cloud maps show that much of the country will be blanketed with clouds, ruining the view of the ethereal dancing illuminations.

There are holes in the cloud cover above parts of Cornwall, Devon, and northern Scotland as well as Northern Ireland – all places that were able to see the lights last night.

There have been sightings reported on Northern Lights detection app Aurora around Edinburgh and Glasgow, as well as in Lincolnshire, around Birmingham and even in London despite the clouds.

Continental stargazers seem to have had more luck, with many sightings reported across the Netherlands, Belgium and Germany.

At the G3 storm level, there may be problems of surface charging on satellites, disrupting services like sat navs and low-frequency radio on the ground.

The best place to see the aurora will be in Scotland and Northern Ireland but it can also be visible from the Midlands and mid Wales. Forecaster AuroraWatchUK has said that it is likely the lights will be visible across the UK.

In some cases, the lights may not be visible to the naked eye and stargazers will have to watch the show using long exposure photographs, a feature that is on many smartphone cameras.

The Met Office has said geomagnetic activity is due to ‘return to background levels’ after tonight, so it is the last chance to see the spectacular show for a while.

Auroras are caused by solar flares – coronal mass ejections (CME) – from the sun which slam into the Earth but are deflected by the planet’s magnetic field.

These deflections are made visible in lights that we call aurora.

This storm is the remainder of last night’s geomagnetic disturbance and was caused by a large CME that fired out from the sun on Sunday, only reaching us a day later on Monday, yesterday.

Despite it being a leftover part of the storm, it is still classified as a strong disturbance.

AuroraWatchUK said that currently there are large peaks of 634.6nT (nanoteslas) in electromagnetism on Earth.

This current storm has a Kp index of seven out of nine, a very high level. Kp index is derived from the German Planetarische Kennziffer, meaning Planetary Index and is used to measure geomagnetic storms.
