The total solar eclipse will cross Greenland, Iceland and northern Spain, where lucky observers will see the Moon completely block the Sun for more than two minutes. The UK will sit just outside the narrow path of totality, but will still enjoy an exceptional partial solar eclipse. When is the solar eclipse in the UK? How to watch the solar eclipse safelyAnyone planning to watch the eclipse must never look directly at the Sun without certified eclipse glasses or suitable solar filters, even when most of the Sun is covered. The solar eclipse is being livestreamed by the Royal Observatory Greenwich from 6.10pm until 8pm.
