How to Watch the Blood Moon Lunar Eclipse This Sunday

Sky-watchers in the UK are in for a celestial treat on Sunday, September 7, 2025. A total lunar eclipse, often called a Blood Moon, will take place, turning the Moon a stunning shade of red as it passes through Earth’s shadow.

This rare event will be partly visible across the UK, while other regions of the world will enjoy the eclipse in full. Here’s everything you need to know about the timings, science, history, and best viewing tips.

What Time Is the Blood Moon in the UK?

The eclipse begins earlier in the afternoon, but UK observers will only see it from moonrise onwards.

• Penumbral phase begins: 4:28 PM BST (17:28 UTC)

• Partial eclipse begins: 5:27 PM BST (18:27 UTC)

• Maximum eclipse: 7:11 PM BST (19:11 UTC) – just before moonrise in the UK

• Moonrise in the UK: Around 7:30 PM BST

• Eclipse ends: By 9:40 PM BST

That means people in the UK will see the Moon already glowing red as it rises in the east.

For those in eastern Africa, the Middle East, much of Asia, and western Australia, the full eclipse will be visible from start to finish.

What Is a Lunar Eclipse?

A lunar eclipse happens when the Earth moves directly between the Sun and the Moon, blocking sunlight and casting a shadow on the Moon’s surface.

There are three main types:

1. Total Lunar Eclipse – The Moon is fully inside Earth’s dark shadow (umbra) and turns red.

2. Partial Lunar Eclipse – Only part of the Moon is covered by the shadow.

3. Penumbral Lunar Eclipse – A faint dimming when the Moon passes through Earth’s outer shadow.

The September 2025 event is a total lunar eclipse, making it one of the most spectacular sky shows.

Why Does the Moon Turn Red?

The red glow of a Blood Moon comes from a phenomenon called Rayleigh scattering.

• Earth’s atmosphere bends sunlight around the planet.

• Blue light is scattered away, while red light passes through.

• This red light reaches the Moon, giving it a deep orange or scarlet hue.

Astronomer Dr Edward Bloomer from the Royal Observatory Greenwich explained: “This is not a special effect. There’s nothing else it could be. It’s the mechanics of the solar system happening in real life right in front of you.”

How to Watch the Blood Moon in the UK

Watching a lunar eclipse is easy, safe, and doesn’t require special equipment. Here’s how to get the best view:

• Find a clear view eastward – preferably a hill, park, or high point.

• Arrive before 7:30 PM BST so you don’t miss moonrise.

• Binoculars or telescopes will enhance the details, but your eyes alone are enough.

• Check the weather forecast – most of the UK should have clearer skies by evening, though the northwest may see showers.

• Take photos – smartphones can capture the red glow, though DSLR cameras work best.

Unlike a solar eclipse, lunar eclipses are completely safe to view with the naked eye.

Historical and Cultural Significance

Throughout history, Blood Moons have been seen as omens of change. Some ancient cultures believed they were warnings of war, famine, or disasters.

In modern times, they are understood as natural astronomical events – but the beauty and rarity still inspire awe worldwide.

The last total lunar eclipse visible in the UK took place in 2022. The next one will happen on August 28, 2026, so mark your calendars.
