Blood Moon Partial Lunar Eclipse: How and When to See It in UK Skies
BBC Weather explores the upcoming partial lunar eclipse, offering guidance on viewing opportunities and celestial phenomena.
Partial Lunar Eclipse Overview
Skywatchers in the UK are set for a rare treat as a partial lunar eclipse graces the night sky on Friday. While cloud cover may pose challenges, the event promises an eerie red glow known as a Blood Moon.
When and How to View
- Eclipse Timing: The eclipse begins at approximately 02:23 BST with the Moon entering the Earth’s outer shadow (penumbra). The main partial phase starts at 03:33 when the Moon enters the darkest part (umbra), reaching its maximum at 05:12.
- Visibility: Due to the Moon setting below the horizon by 06:51, the eclipse ends without being visible in the UK.
- Best Viewing: Southern and eastern England, Northern Ireland, and western Scotland offer the best chances of clear skies for optimal viewing.
Moon Illusion Enhances Spectacle
The low position of the Moon close to the horizon creates an optical illusion known as the Moon illusion, making the eclipsed Moon appear larger and more dramatic.
Red Moon Explained
During a lunar eclipse, sunlight scattered through Earth’s atmosphere reaches the Moon, with red wavelengths reflecting back due to scattering. This results in the Moon’s distinctive reddish hue during the partial eclipse.
Weather Considerations
For the best experience, find a high location with an unobstructed view of the south-western horizon. Clear skies are crucial, and weather forecasts suggest low pressure overhead, increasing cloud cover probabilities.
