The Corn Moon, September’s full moon, will rise in skies across the UK this weekend.
This year’s spectacle is particularly special as it coincides with a lunar eclipse, which is the moment the Earth moves between the Sun and the Moon. During this event, direct sunlight is prevented from reaching the Moon, turning its surface a deep crimson hue – hence the name 'blood moon'.
If skies are clear, much of the UK should be able to see at least part of the eclipse.
What is the Corn Moon?
Corn Moon is the name given to September 2025's full moon. The name comes from Native American and European traditions and marks the start of the harvest season. At this time of year, the Moon's golden glow was once relied upon by farmers to guide them as they gathered crops at dusk.
September's full moon is sometimes known as the Harvest Moon. The Harvest Moon is the closest full moon to the autumn equinox, which this year falls on 22 September. So, as the following full moon rises on 6 October (closer to the equinox than early September's full moon), this year it will take the name Harvest Moon.
What is a Blood Moon lunar eclipse?
This year’s Corn Moon coincides with a lunar eclipse. As the Sun, Earth and Moon all line up, sunlight refracts through Earth's atmosphere, casting a dark, red shadow across the Moon's surface. That's why it's often called a 'Blood Moon lunar eclipse'.
When to see the Blood Moon lunar eclipse
Look out for the Corn Moon on Sunday 7 September, when it rises in the east at sunset – it will appear in the UK at approximately 19:45.
By the time it rises, the Moon will already be totally eclipsed. Even if skies are clear, the shadow cast by Earth may make it difficult to see the Moon at first. Now's the time to be patient.
As the Moon rises, Earth's shadow will begin to move away from the Moon and its surface will gradually appear.
