Rare sightings of the <a href="https://www.thenationalnews.com/uae/2022/03/07/uaes-hope-probe-tracks-enormous-dust-storm-on-mars/" target="_blank">aurora borealis</a> in parts of the <a href="https://www.thenationalnews.com/uk/" target="_blank">UK</a> on Sunday night were due to the strength of a geomagnetic storm and a "strip of cloudless skies" in southern regions, the Met Office said. The spectacular display could be visible to stargazers again on Monday night, after the Northern Lights were seen in Sunday’s night sky as far south as Cornwall, it added. The Northern Lights, also known as the aurora borealis, are visible occasionally in the night sky over Britain. They appear as large patches of various colours, from pale green to pink, red, yellow, blue and violet. The Northern Lights are caused by solar winds colliding with molecules in the <a href="https://www.thenationalnews.com/climate/environment/2022/10/26/earth-set-to-warm-by-well-over-2c-as-world-nowhere-near-climate-targets/" target="_blank">Earth</a>'s upper atmosphere, resulting in various colours of light appearing in the sky. The arrival of what meteorologists call coronal mass ejections (CME) from the Sun can bring the lights to lower latitudes, making them potentially visible in the UK. The Met Office shared pictures taken by the public that captured the phenomenon in various regions on Sunday, including <a href="https://www.thenationalnews.com/tags/scotland/" target="_blank">Scotland</a>, North Wales, Cambridgeshire and Shropshire. Alasdair O'Dell, 40, from Dunbeg in south-west Scotland, managed to capture the lights in Connel, near where he lives. "I'll always try and see the Northern Lights if possible," he said. "It's a really exciting natural phenomenon. "We are lucky enough to see them sometimes in Scotland — when it's not raining — but Sunday night was the most spectacular show I've seen since I've been here. I'll be out again [on Monday night] with my camera." Craig Smith, 43, who works in construction and lives in Blackburn, Lancashire, also managed to photograph the Northern Lights flickering in the skies above his hometown. He said: "I've seen the lights on several occasions from home ... always great to see. The [coronal mass ejection] that hit Earth yesterday evening put on a great show. "The lights were dancing. It's just a shame the clouds began rolling in just as it started." The Met Office has offered advice for seeing the aurora, such as finding a dark location with no light pollution and looking north. It also warned that geomagnetic activity can disrupt satellite navigation systems. It encouraged people to share their sightings of the Northern Lights by using the hashtag #LoveUKWeather.
