uncommon tremendous blue moon will seem over the UK on Thursday evening, treating stargazers to a phenomenon that may solely occur as soon as this 12 months.

Unlike its title suggests, a blue moon shouldn't be named after the color and as a substitute refers back to the second full moon in a single calendar month.

Most months solely have one full moon, so a second is a fairly a uncommon occasion, occurring roughly as soon as each two or three years.

The moon seems bigger than common, and can rise at round 8pm (BST) on Thursday, setting round 6am (BST) the next day.

The peak of the complete moon – when the close to facet of it's utterly lit up by the solar is at 2.35am (BST) on Friday morning.

However, those that won't have the ability to keep up into the early hours don't want to fret concerning the even, as specialists say it won't look noticeably totally different in the course of the evening.

Instead, the very best time to catch a glimpse is when your native situations are greatest suited to a transparent sky – low cloud cowl, beneficial climate, and no obstructions on the horizon – equivalent to buildings or bushes.

Astronomer Professor Don Pollacco, division of physics, University of Warwick, stated: “One of the flukes of nature is that the apparent size of the moon can be very similar to that of the sun.

“This occurs because, while the moon is much smaller than the sun, it is much closer to the Earth.”

Adding that the moon has and elliptical orbit across the Earth, he continued: “Now that we understand the Moon’s orbit around the Earth we can talk about super moons.

“These occur when there is a full moon at the time when the moon is closest to the Earth.

“Consequently, the moon can look bigger (10-15%) and brighter (25-30%) than a normal full moon.”

Prof Pollacco stated: “To see the full moon, look east after sunset. If you have a clear horizon it should be obvious.

“The moon is so bright that we can see it when it’s not particularly dark or even if the weather isn’t particularly clear.

“It will be visible all night and set in the west around sunrise.”

Dr Greg Brown, astronomer at Royal Observatory Greenwich stated: “August brings the joining of two rare events in astronomy: a blue moon and a supermoon.

“However, both events have somewhat complicated definitions, and none are universally accepted.

“The most common definition of a blue moon is that it is the second full moon in one calendar month.”

He added: “A supermoon, on the other hand, is a full moon that occurs when the moon is in the closest part of its orbit around the Earth, though exactly how close it needs to be to make it ‘super’ is up for debate.

“During this time, the Moon will appear a little bigger and brighter than it normally does, though the difference is hard to spot by eye.”
