The Moon event is expected to be visible at dawn, when the moon is at its closest point to Earth although full illumination will not occur until later in the day just after sunset.
According to Patricia Skelton, an astronomer at the Royal Observatory in Greenwich the best time to see the supermoon in the UK will be in the early hours of the morning on May 26, or later in the evening on the same day – after sunset.
Talking to The Evening Standard, she said: “A supermoon happens when a full moon occurs at the same time, or close to the time, that the moon reaches its closest point to the Earth – a point called perigee.
“Perigee occurs at 2.51am on May 26, with full moon occurring at 12.14pm on the same day.
“The supermoon will rise in the east around half an hour after sunset and will be visible throughout the night.”
