A total solar eclipse will be visible on Wednesday, August 12, in what is described as the clearest event of its kind since 1999. The Moon will move between the Sun and Earth, blocking light and casting a shadow for just under two hours in the evening.
UK Visibility and Coverage
In the UK, the Moon will begin to cover the Sun's edge, known as first contact, at around 6:17pm, reaching maximum at around 7:12pm and finishing at around 8:06pm, depending on location. People in London should see about 90% of the Sun covered, the greatest coverage visible from the UK in 27 years.
Other European countries will fare even better, with France, Belgium, Switzerland, and northern Italy seeing 88% to 95% coverage.
Path of Totality
The path of totality, where the Moon fully blocks the Sun, crosses parts of Greenland, Iceland, Portugal, and northern Spain. Spectacular views are expected around western Iceland, including Reykjavík, Reykjanes, Snæfellsnes, and the Westfjords.
Spain is also an ideal viewing location, as the eclipse will occur near sunset, and weather conditions are more reliably clear.
Safety Precautions
Viewers must take proper safety precautions, as looking at an eclipse with the naked eye can cause damage. Bright rays from the Sun can burn retinal cells, and since the retina lacks pain receptors, damage may go unnoticed. This can lead to vision loss or permanent blurry spots.
It is recommended to wear ISO 12312-2 certified eclipse glasses, which allow only a small amount of light through. Regular sunglasses are not sufficient, as they do not block enough light and can still cause permanent eye damage. Legitimate eclipse glasses will have the safety certification printed on them.
