How to watch the Flower Moon in the UK

It’s set to take place on Wednesday, May 26 – and is known as a Flower Moon.

That’s the traditional name for the fifth full Moon of the year, and doesn’t mean anything in particular about its shape, size or colour.

However, it’s expected to be big and bright, and sport an orange-gold hue.

That’s because it’s a Super Moon, a reasonably rare lunar spectacle.

A Super Moon is a combination of two different astronomical effects.

It’s when a new or full Moon coincides with a perigee – the Moon’s closest point to Earth in its monthly orbit.

A Moon has to come within 90 per cent of its closest approach to Earth to be formally defined as a Super Moon.

That means the Moon needs to come within 224,865 miles of Earth and be a full Moon to boot.

According to Nasa, the May 26 event is the year’s “most super” moon.

When is the Flower Super Moon 2021 in UK?

In the UK, the Full Flower Moon will occur on May 26 at 11.32pm.

It will be possible to see the Super Moon on May 25 and May 26 in the UK.

The Moon will appear full for around three days, from Monday to Thursday.

Can you catch the full lunar eclipse 2021 in the UK?

Also on May 26, a full lunar eclipse will be visible from certain parts of the world.

The rare celestial event take place above the US, Australia, western South America and Southeast Asia.

Unfortunately, it won’t be visible from the UK but stargazing fans will be able to watch it over a live-stream on May 26.

Time and Date will be live-streaming the event on YouTube on Wednesday at 5.30am ET (10:30am BST).

What is a Super Moon?

First, you need a full Moon, which is when the Moon is fully illuminated from Earth’s perspective.

For that to happen, Earth needs to be located between the Sun and the Moon.

That means we’re seeing the entire full face of the Moon lit up by the Sun.

Although the Earth is between the Sun and the Moon, it doesn’t create an eclipse because the Moon’s position relative to our home planet is slightly skewed.

And for a Super Moon, you also need the Moon to be in the correct position in orbit around Earth.

The Moon has an elliptical orbit, and isn’t always the exact same distance from Earth.

Its closest point is called the perigee, and its farthest is the apogee.

The different types of Moons

Here are some of the most interesting moon phases and when to see them…

Blue Moon refers to the occasion when a full moon appears for the second time in the same month, this is rare and the next Blue Moon should occur in August 2023.

The Harvest Moon appears around the time of the autumnal equinox when farmers tend to do their main crop harvesting, the next one will appear in September 2021.

Super Moon appears when it is at its closest point to Earth and therefore at its brightest, the next one will appear in May 2021.

Blood Moon occurs during a total lunar eclipse, the next one should happen in May 2021.

Each month of the year actually has its own special full moon name, as follows:

  • January: Wolf Moon
  • February: Snow Moon
  • March: Worm Moon
  • April: Pink Moon
  • May: Flower Moon
  • June: Strawberry Moon
  • July: Buck Moon
  • August: Sturgeon Moon
  • September: Full Corn Moon
  • October: Hunter’s Moon
  • November: Beaver Moon
  • December: Cold Moon

With a full Moon at the perigee, you get a Super Moon.

And with a full Moon at the apogee, you get a Micro Moon.

Super Moons are relatively rare, occurring just three or four times in a single year.

That’s because you need a full Moon to occur alongside close-to-Earth orbital positioning.

The 2021 Super Moons are in April and May, although the March Moon was very large – as the June Moon will also be.

Many astronomers stick to a strict definition of what makes a Super Moon, which only considers the closest Full Moons at perigee in a given year.

By this definition, there will be two Super Moons this year: Super Pink Moon on April 27 and Super Flower Moon on May 26 respectively

Thankfully, they’re easier to spot than almost any other astronomical phenomenon.
