A partial lunar eclipse, popularly known as a 'blood moon', will be visible from London in the early hours of Friday, August 28, 2026. The celestial event will reach its maximum at 5.12am, with around 93 percent of the moon passing through the Earth's umbra, the darkest part of its shadow. This follows the partial solar eclipse that captivated the city a fortnight earlier.
What is a lunar eclipse and why does it happen?
A lunar eclipse occurs when the moon passes through the darkest part of Earth's shadow, known as the umbra. This phenomenon happens around the world two to four times per year, but it can only be seen from specific places once every year and a half. Total lunar eclipses occur every two-and-a-half years.
According to Amy Houghton of Time Out London, the lunar eclipse is no coincidence with the recent solar event. A lunar eclipse always happens roughly two weeks before or after a solar eclipse. While not as rare as the solar event, it remains a sight to behold.
When and where to watch the blood moon in London
The partial lunar eclipse will begin at 3.33am and reach its maximum at 5.12am on Friday, August 28. Most major London parks will be closed at that time, so popular spots like Primrose Hill and Greenwich Park will not be accessible. However, Hampstead Heath is open 24 hours, making Parliament Hill a viable option for skywatchers.
As the eclipse progresses, the moon will descend lower on the horizon. Observers should seek a high point with a clear, uninterrupted view to the southwest. The Met Office forecasts partly cloudy skies in the early hours of Friday, which may affect visibility but should not entirely obscure the moon.
How to safely observe the lunar eclipse
Unlike a solar eclipse, no special glasses are required to view a lunar eclipse. The moon can be observed directly without any risk of eye damage. For a closer look at the moon's surface, binoculars are recommended.
The lunar eclipse offers a rare opportunity for Londoners to witness a celestial phenomenon without leaving the city. With Hampstead Heath open and the moon visible from high points, the event promises to be a memorable experience for early risers.
