WHEN CAN YOU SEE IT?
The supermoon will arrive today. It will be the second supermoon of the year, the first having already happened on October 16, and the third expected on December 14.
At 8.09 PM GMT (3.09 PM ET) the moon will be the closest it has been to the Earth since 1948, at a distance of around 217,000 miles (350,000 km).
This will be when the moon is at its biggest and brightest during the day.
But the whole of the UK looks set to be covered in a cloak of cloud cover around 8PM GMT, according to the Met Office.
Even if your view is not clear, Slooh Observatory will be doing a live broadcast.
‘I’ve been telling people to go out at night on either Sunday or Monday night to see the supermoon,’ said Noah Petro, deputy project scientist for NASA’s Lunar Reconnaissance Orbiter (LRO) mission.
‘The difference in distance from one night to the next will be very subtle, so if it’s cloudy on Sunday, go out on Monday. Any time after sunset should be fine.
