Also known as the Aurora Borealis, the Northern Lights are considered one of the most spectacular displays we can see in the night sky.
This "incredible occurrence" can occasionally be spotted in the sky over Britain, with sightings over recent years becoming more frequent.
Now, the Met Office is predicting them to once again be visible over parts of the UK tonight, as far south as East Anglia.
The Northern Lights may be visible in parts of the UK "late on September 1, or early on 2 September 2.
The Met Office added that this will "potentially continue" into September 3.
The Space Weather forecast from the Met reads: "The auroral oval is expected to remain mostly at background levels initially, with only minimal enhancements.
However, a fast-moving coronal mass ejection (CME) that departed the Sun late on August 30 is forecast to arrive at Earth late on September 1 or early on September 2.
"Following its arrival, a significant enhancement of the auroral oval is likely, potentially continuing into September 3."

The Northern Lights are expected to be visible in the northern parts of England, as well as Scotland.
However, the Met adds that at peak activity, and where skies are "sufficiently dark and clear", the aurora may be visible as far south as East Anglia, the Midlands, Wales, and other regions at similar geomagnetic latitudes, without the need for photographic equipment.
However, a waxing gibbous Moon may hinder visibility in some areas.
It is best to attempt to view the Northern Lights in a dark place with little to no light pollution.
While they are sometimes difficult to spot with the naked eye in the UK, your phone can take some stunning snaps.
For the top pictures, the BBC's Sky at Night magazine recommends a DSLR or bridge camera which lets you control the ISO and exposure time.
Krista Hammond, a manager at the Met Office Space Weather Operations Centre (MOSWOC), said: "Activity on the sun, and in particular the number of visible sunspots, varies over roughly an 11-year period, known as the solar cycle."
The last solar minimum, which is when the Sun had the lowest frequency of visible sunspots in the solar cycle, occurred in December 2019.
This means that the sun's activity is currently increasing.
As a result, more of the Sun's electrically charged particles are travelling towards the Earth and getting caught in its magnetic field, thus producing more of the aurora effect.
Krista added: "Over the coming years, as we continue towards the solar maximum, we can expect to see an increase in the frequency of space weather events, with more chances to see the Aurora Borealis over the UK."
The Royal Museums Greenwich explained: "Solar storms on our star's surface give out huge clouds of electrically charged particles. These particles can travel millions of miles, and some may eventually collide with the Earth.

"Most of these particles are deflected away, but some become captured in the Earth's magnetic field, accelerating down towards the north and south poles into the atmosphere. This is why aurora activity is concentrated at the magnetic poles."
Royal Observatory astronomer, Tom Kerss added: "These particles then slam into atoms and molecules in the Earth's atmosphere and essentially heat them up.
"We call this physical process 'excitation', but it's very much like heating a gas and making it glow."
