The best solar eclipse visible from the UK in almost 27 years is happening on Wednesday, August 12.
The moon will move to cover the sun in a total solar eclipse for people in Greenland, Iceland and Northern Spain.
The UK will only experience a partial eclipse, but around 90% of the sun will be covered by the moon meaning people should still be in for a spectacular sight in the skies.
It is the most complete eclipse seen in the UK since 1999.
Millions of people will be wanting to catch a glimpse in London, with the hope of clear skies to see the phenomenon in all its glory.
So as the moment approaches, the all-important question for any outdoor event in London will be asked “what is the weather forecast?”

The eclipse takes place in summer, so there's a better chance of clear skies than you'd expect in autumn or winter.
You can never 100% predict the weather.
But with just two days to go the forecast is looking extremely promising, with the expectation of clear skies and temperatures in the high twenties.
On Monday, August 10, the Met Office forecast was for bright sunshine and 29C at 6pm on Wednesday, with clear skies throughout the evening.
This year’s solar eclipse will begin at 6.17pm.
The whole phenomenon will last around an hour and 49 minutes until 8.06pm.
The height of the eclipse is expected at 7.13pm for Londoners.
