A total solar eclipse will occur on Wednesday, Aug. 12, 2026 [1], with a near-total partial eclipse visible across the UK and Ireland [2].
The event provides a rare opportunity for millions of people to witness a significant celestial alignment, though it requires strict safety precautions to prevent permanent eye damage.
The path of totality — where the Sun is completely obscured by the Moon — will pass over Greenland, Iceland, northern Europe, and the Arctic [3]. In other regions, the eclipse will appear as a partial event. In the United Kingdom, observers can expect the Moon to cover 90% or more of the Sun [4].
Astronomer Dr. Jenifer Millard said the public must use proper eye protection to watch the event safely [5]. Looking directly at the Sun without specialized solar filters can cause severe retinal burns, even during a partial eclipse when the light is dimmed.
Safe viewing methods include using certified eclipse glasses or indirect projection techniques. Experts said that standard sunglasses do not provide sufficient protection against the intense solar radiation that remains visible during the partial phases [5].
Observers in the UK and Ireland will experience a noticeable drop in temperature and a change in the quality of light as the Moon moves across the solar disk. This phenomenon occurs because the Moon passes directly between Earth and the Sun, casting a shadow across the planet's surface [2].
While the total eclipse is limited to the far north, the high percentage of coverage in the British Isles makes this one of the most significant astronomical events for the region in recent years [4].
“The Moon will cover 90% or more of the Sun in the UK.”
This eclipse highlights the importance of public science literacy regarding solar safety. Because a 90% partial eclipse can create a deceptive dimming of light, viewers may mistakenly believe they no longer need protective eyewear, increasing the risk of ocular injury across Western Europe.
