The South West will see part of the sun covered by a solar eclipse this evening.
The USA will have a total eclipse but Britain will see a much smaller version with around 4% of the sun blocked by the moon.
Beginning at around 7.40pm, the partial eclipse will last until just before 8.30pm.
The weather could affect people's ability to see the eclipse clearly, with cloud forecast across much of the South West.
But crowds are still predicted in many South West cities as people watch the astronomical event.
As with any eclipse, people are being warned not to look directly at the sun.
The next major eclipse visible in the UK won't occur until August 12, 2026, when around 95% of the sun will be covered.
Britain will not see a total solar eclipse until September 23, 2090.
