WEST END FINAL

London will see its most complete solar eclipse in over a quarter of a century today.

The phenomenon means the Moon will pass directly between the Earth and the Sun, blocking the Sun’s light almost entirely.

It is estimated that around 90% of the Sun will be covered by the Moon, triggering a rare and stunning natural phenomenon.

There won’t be a better eclipse in Britain until 2090, so you won’t want to miss this one.

But the phenomenon isn’t without its risks and Londoners should take care as they try to catch a glimpse.

Here is everything you need to know about the solar eclipse.

An eclipse occurs when the Moon moves directly between the Sun and Earth. This blocks the light of the Sun to part of Earth, totally or partially.

The type of solar eclipse you experience depends on the relative positions of the Sun, Earth and Moon, as well as where exactly on Earth you’re watching from.

There will be a partial eclipse on Wednesday. It is a rare event because of how much of the Sun will be blocked.

When is the solar eclipse and what is the best time to watch?

This week’s solar eclipse will begin at 6.17pm for those based in London, Bristol, and Cardiff.
