The northern lights UK display put on a spectacular show on Friday and Saturday evening, with sky-gazers as far south as Devon, Hampshire and Kent treated to the dazzling aurora borealis. The Met Office said sightings could continue during clear skies until Tuesday, giving more people a chance to witness the rare phenomenon.
What Caused the Northern Lights UK Display?
The aurora borealis is a natural light display driven by solar activity and geomagnetic storms interacting with the upper atmosphere. According to the Met Office, the sun emits charged particles known as solar wind, which travel at about 1 million mph. When these particles interact with Earth's magnetic field – especially when the solar wind's polarity is opposite to Earth's – they are funnelled toward the magnetic poles.
As these energetic particles collide with gases in the upper atmosphere, they release energy in the form of light. Oxygen produces green and, at higher altitudes, rare red auroras, while nitrogen creates blue and purple hues. This collision process is what creates the colourful displays seen in the sky.
Where Was the Aurora Borealis Visible?
Such occurrences are mostly visible near the Arctic Circle and northern Scotland, but this geomagnetic storm pushed the aurora further south than usual. Sky-gazers in Devon, Hampshire and Kent were among those who captured stunning images. The Met Office said sightings will remain possible until Tuesday across Scotland and similar geomagnetic longitudes during clear skies.
How to See the Northern Lights in the UK
To maximise your chances of spotting the aurora, you need dark skies, clear weather and a little patience. Here are some key takeaways:
- Check the forecast: Use the Met Office aurora forecast and space weather apps to track geomagnetic activity.
- Find dark skies: Head away from city lights to rural areas, coastlines or designated Dark Sky Parks.
- Look north: The aurora typically appears low on the northern horizon, so face that direction.
- Be patient: Displays can be fleeting; give your eyes time to adapt to the dark.
- Use a camera: A long-exposure shot can reveal colours invisible to the naked eye.
Northern Lights UK vs Other Locations
While the UK occasionally gets a glimpse, traditional aurora hotspots offer more consistent viewing. Here's how they compare:
| Location | Frequency | Best Time |
|---|---|---|
| Northern Scotland | Occasional | September–March |
| Devon, Hampshire, Kent | Rare (during strong storms) | Any clear night |
| Tromsø, Norway | Very frequent | September–April |
| Reykjavik, Iceland | Frequent | September–March |
| Fairbanks, Alaska | Very frequent | August–April |
Why the Northern Lights UK Sightings Are Increasing
Solar activity follows an approximately 11-year cycle, and we are currently near the solar maximum, which means more frequent geomagnetic storms. This increased activity is why the aurora is being seen further south than usual. The Met Office continues to monitor space weather and will issue updates when conditions are favourable.
