A partial solar eclipse will be visible across London and the United Kingdom this Wednesday, 12 August 2026 [1], [2].
The event represents a significant astronomical occurrence for the region. According to the BBC, the UK will experience the best solar eclipse since 1999 [2].
The phenomenon occurs when the moon passes directly between the Earth and the sun, partially blocking sunlight [2], [3]. During this alignment, approximately 90% of the sun will be covered by the moon [1].
Residents in London can observe the eclipse from various city viewing spots [1], [4]. Because looking directly at the sun can cause permanent eye damage, experts said to use certified solar filters or eclipse glasses to watch the event safely [2].
"Around 90% of the sun will be covered by the moon," the Evening Standard said [1].
Observers are encouraged to seek out open areas with a clear view of the sky to witness the darkening of the daylight. The partial eclipse is expected to be visible to the wider UK public as the moon moves across the solar disk [1], [2].
“Around 90% of the sun will be covered by the moon.”
This event marks the most significant solar eclipse visible from the UK in nearly three decades. While not a total eclipse, the high percentage of obscuration will create a noticeable drop in ambient light, providing a rare opportunity for large-scale public scientific observation and engagement across the country.
