When to see the 'supermoon' in the UK this week
Skygazers in the UK may be able to spot a 'supermoon' on Wednesday.
The celestial event is expected to be visible at dawn on 26th May, when the moon is at its closest point to Earth, although full illumination will not occur until later in the day.
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 Wednesday morning on, or later in the evening on the same day – after sunset.
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 26th May, 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.”
During this time, the Earth’s natural satellite will appear around 14 per cent bigger and 30 per cent brighter.
Ms Skelton said: “For the best views of the supermoon, wait for the moon to climb higher up into the sky.”
The event also coincides with a lunar eclipse which will see the moon turn red, but that will not be visible in the UK, Ms Skelton said.
“People viewing the supermoon from the western US, western parts of South America, Australia or south-east Asia will witness the supermoon turn a shade of crimson red as a lunar eclipse will be taking place on the same day," she said. “This change in colour is not due to a physical change taking place on the moon, but simply because the moon will drift into the shadow of the Earth.
“The Earth’s atmosphere bends light from the sun and bathes the moon in a crimson red light.
“Although UK stargazers won’t be able to see the lunar eclipse, the supermoon is still worth a look.”
