Residents across the United Kingdom were treated to a rare celestial display as the Northern Lights, or Aurora Borealis, became visible as far south as the English south coast on Friday and Saturday evenings. The phenomenon, caused by increased solar activity, typically occurs near the Arctic Circle and northern Scotland, but exceptionally strong solar eruptions directed towards Earth allowed the aurora to be seen in regions as far south as Devon, Hampshire, and Kent. The Met Office confirmed that geomagnetic activity reached 600nT (nanotesla) on Saturday evening, a level that usually only permits visibility in northern UK regions, making the southern sightings particularly unusual. The aurora is created when charged particles from solar coronal mass ejections collide with Earth's magnetic field and atmosphere, producing vibrant colours through interactions with oxygen and nitrogen. Experts noted that such widespread visibility is rare, with the last similar event occurring years ago. The Met Office advised that clear skies until Tuesday could provide further opportunities for viewing, though the best chances remain in northern regions. For optimal viewing, observers were encouraged to look northward away from artificial light sources and use mobile phone cameras, as human eyes perceive the aurora in monochrome under low-light conditions while cameras capture the full spectrum of colours. The phenomenon is expected to peak in 2026 as part of the Sun's 11-year solar cycle, offering potential for more frequent and widespread displays in the coming years. This event follows a period of heightened solar activity, with the Sun releasing powerful coronal mass ejections towards Earth late last week. The BBC Weather Watchers contributed numerous photographs capturing the aurora's vivid hues across various UK locations, including Kendal in Cumbria, Winterton-on-Sea in Norfolk, and Saltburn-by-the-Sea in Redcar and Cleveland. The display has been described as a breathtaking natural spectacle, drawing crowds to open spaces to witness the rare phenomenon.
