On 12 August, a notable solar eclipse will be visible across western Europe, including the United Kingdom. While the UK lies just outside the path of totality, many regions can expect the Moon to obscure between 89% and 96% of the Sun’s surface. The eclipse is scheduled to begin around 6:15 p.m. and conclude shortly after 8 p.m. local time.

A solar eclipse occurs when the Moon passes between the Earth and the Sun, casting a shadow over parts of the planet and temporarily blocking sunlight. The UK will not see a total solar eclipse again until 23 September 2090, making this event a rare opportunity for observers, according to Catherine Heymans, Scotland’s Astronomer Royal. She described the experience as a magical alignment that allows viewers to witness celestial motion in real time.

Optimal viewing conditions require an unobstructed view of the low western horizon, so locations at higher elevation or along coastlines will provide the best vantage points. The Isles of Scilly will experience the highest eclipse coverage in the UK, while mainland Cornwall and the southwest can expect up to 95% coverage, the closest approximation to totality on the mainland.

In London, about 91% of the Sun will be obscured, but buildings could impede sightlines due to the Sun’s low position. Suitable viewing locations in the capital include hilltops and open spaces such as Blackheath, Hampton Court Palace, Primrose Hill, Gotford’s Hill, and Blythe Hill. Viewing from bridges over the Thames or rooftop venues is also viable. Local astronomy groups will hold viewing events with equipment and guidance, including the SW London Astronomers in Tooting Common and the Loughton Astronomical Society near Chingford.

Safety remains paramount when observing a solar eclipse. Experts caution against looking directly at the Sun without proper protective eyewear, as this can cause permanent eye damage. Normal sunglasses do not provide adequate protection. Eclipse glasses meeting the international ISO 12312-2 safety standard are recommended and should be purchased from trusted suppliers. Organizations such as the Royal Observatory and optics retailers offer certified glasses, and indirect observation methods, such as pinhole cameras, are also advised.

Beyond the eclipse itself, observers may also benefit from an overlap with the Perseid meteor shower, which peaks around the same time and offers visibility of shooting stars once darkness fully sets in. Some observers may notice unusual shadow effects or a subtle change in light quality due to the partial obscuration of the Sun.

Across the UK, various astronomy clubs and observatories are organizing events to mark the occasion. The National Space Centre in Leicester will host family-friendly activities and live astronomy demonstrations. In Hampshire, Fordingbridge Astronomers plan a free event with safe viewing followed by a meteor shower picnic. Similar gatherings are scheduled at Battlesteads Observatory in Northumberland, Bossington Hall in Somerset offering accommodation packages, and venues in Cornwall, which will include an aerial display in Falmouth coinciding with the eclipse.

Additional events will take place in Edinburgh, Glamorgan’s Rest Bay, and Armagh Observatory, where outreach activities and public viewing opportunities are arranged.

For individuals inspired by this eclipse, a more extended total solar eclipse is due on 2 August 2027. Its path of totality will cross parts of Egypt, Algeria, Gibraltar, Morocco, Saudi Arabia, and Tunisia. Near Luxor, Egypt, the eclipse will last up to six minutes and 23 seconds. Travel companies are already offering guided tours for this event, including expert-led excursions in remote locations such as Morocco’s Rif Mountains.
