The Northern Lights lit up skies across the UK on Monday night, offering a rare autumn spectacle from Scotland and north Wales to Norfolk, Kent and even Dorset. Forecasters say the dazzling display could return for a second night, depending on solar activity and cloud cover.
Why Did the Aurora Appear?
The phenomenon followed a powerful solar storm triggered by a coronal mass ejection (CME) from the Sun. When these bursts of solar energy reach Earth, they interact with oxygen and nitrogen in the atmosphere, producing the greens, purples and reds of the aurora.
How Strong Was the Storm?
The US Space Weather Prediction Center confirmed a moderate G2 geomagnetic storm early Tuesday. The UK’s Met Office Space Weather Centre warned activity could intensify to a G4 “Severe” level—just one step below the maximum on the G1–G5 scale—raising chances of the aurora being visible across much of the country.
Where and When to See It
- Best chance: Scotland, where skies will remain clearest overnight.
- Lower chance: England, Wales and Northern Ireland, where thickening cloud, heavy rain and strong winds may obscure visibility.
- Light pollution: Urban areas may still miss the display, though photography can reveal auroras not visible to the naked eye.
Tips for Photographing the Aurora
- Use a tripod to keep your camera steady.
- Set a long exposure (3–5 seconds on phones with night mode).
- Turn off flash.
- Adjust shutter speed and ISO if your app allows.
The Science Behind the Lights
Auroras occur when charged particles from the solar wind collide with Earth’s magnetic field, exciting gases in the atmosphere and producing shimmering curtains of coloured light. While northern parts of the UK often glimpse the lights, sightings further south typically require unusually strong solar storms—like the one triggered late Saturday night.
The Met Office cautions that activity should return to normal levels by Wednesday, making Tuesday night likely the last chance to catch the display this week.
