A near-total solar eclipse will occur in the skies above Britain this week, prompting warnings about the dangers of watching the spectacle without taking precautions.
The eclipse will begin around 8.30am on Friday and last for two hours as the moon moves in front of the Sun.
The proportion of the Sun covered by the moon will increase the further north you are.
In London, 84% of the Sun will be covered, while in Edinburgh the proportion is 93%.
The last solar eclipse of such significance took place in August 1999, when a total eclipse occurred.
