Across the UK people watched a very rare solar eclipse, where the Moon covered up the Sun.
The UK saw a partial eclipse, where a bit of the Sun still shone out from behind the Moon.
There were worries that cloudy weather would spoil the view across the UK, but thankfully some areas had a clear sky for the special moment.

These lemurs were snapped watching the eclipse.
Tim Rowlands, curator of mammals at Chester Zoo, said: "The animals were as fascinated with the eclipse as we were. It was quite a sight to behold."

Later today we'll update this page with the best videos of the eclipse.

King Willem-Alexander and Queen Maxima of the Netherlands took a moment to watch the eclipse during a visit to Hamburg, Germany.
Getting ready on the Isle of Lewis, special eclipse specs deployed!
The rain and clouds cleared up for Ayshah on the Isle of Lewis in the far north of Scotland. Suddenly, the Sun was out - ready to be blocked by the Moon.
An eclipse can be a confusing experience for many animals. Nature expert Mark Champion from the Lancashire Wildlife Trust visited the Newsround studio to explain.
I'm with my buddies, eagerly awaiting the eclipse at the Keele Observatory, I've been waiting 16 years for this moment!
Thanks to Ross and Kyla who sent us their pic of their viewing boxes, from Midlothian, Scotland.
This snap of the eclipse was taken by photographer Toby Melville in Bridgewater, south west England. A special filter has been applied to the camera lens to keep the photographer and the equipment safe.
Ayshah is with BBC weather reporter Carol Kirkwood, hoping the clouds will lift so they can see the eclipse.
Ayshah said: "It's freezing cold but the Sun keeps popping out, so we're hoping to glimpse the eclipse!"
"I'll be at school but I'll still keep a look out for how dark it will get - can't wait!"

A partial eclipse has begun in the south of the UK. People in Cornwall are "first contact" - this is the very first moment the Moon begins to pass in front of the Sun.
BBC reporter John Maguire posted his photo on Twitter.
Ayshah is here with our second morning bulletin, live from the Isle of Lewis.
"My school is not allowed to watch the solar eclipse in case we damage our eyes."

He told Newsround: "It's a very special day because it's the first eclipse we've had since 1999 and probably the last big one we'll have until I'm 87 years old!"
The next full solar eclipse in the UK won't be until 2090, but there will be another few partial solar eclipses before then.
People living further north in the UK will see more of the Sun covered by the Moon.
At 8.18am the southern tip of the UK will begin to see a partial eclipse.
9.30am The partial eclipse in London will reach its maximum.
9.35am Edinburgh will see a maximum partial eclipse, covering 93% of the Sun.
9.42am The total eclipse will happen in the Faroe Islands.
The BBC Weather team have produced this map showing the best place to see the eclipse.
A solar eclipse occurs when the Moon's orbit lines up in between the Sun and the Earth.
The Moon blocks out the Sun's light for a short time, casting a shadow over our planet.
It's a rare event and only possible when the Moon is at exactly the right distance from the Earth.
Today is the day of the eclipse so we've sent our reporter Ayshah to the Isle of Lewis off the coast in Scotland.
That's the best place to see the eclipse in the UK - as long as it's not cloudy.
She'll be sending us updates all morning.
