The partial lunar eclipse due on Friday, August 28, will obscure 93 per cent of the Moon at its peak, making it one of the most significant such events visible from the UK and Ireland in recent years. Maximum coverage is scheduled for 5.12am, according to the Liverpool Echo, but forecast rain and cloud in London could spoil the view for many stargazers.
Eclipse Details and Global Visibility
The Royal Museums Greenwich confirmed that roughly 93 per cent of the Moon will be covered by Earth's deepest shadow during the eclipse's peak. This follows the solar eclipse earlier this month, offering another chance for astronomical observation.
The spectacle will be visible across North and South America, Africa, and parts of Europe. Unlike a solar eclipse, no protective eyewear is required, making the event accessible to a wider audience.
London Weather Forecast Raises Concerns
The Met Office has forecast a dramatic shift from the summer heatwaves, with substantial rainfall and possible thunderstorms from Wednesday onwards. Deputy Chief Forecaster Mark Sidaway noted that some areas could see 20 to 30mm of rain in just a few hours, with higher totals possible where thunderstorms repeatedly affect the same locations.
According to the Met Office, cloud is forecast for the eclipse's peak, with a 50 per cent chance of rain. This uncertainty may disappoint those hoping to observe the event.
Viewing Tips and Scientific Context
If clouds part in time, the eclipse is best viewed from an elevated position with an unobstructed southwest outlook. Those without high ground access are advised to seek the clearest view toward the southwestern horizon.
During a near-full partial eclipse, the Moon may appear red due to Rayleigh scattering, the same phenomenon that makes the sky blue, as different wavelengths of light scatter through Earth's atmosphere.
As the week progresses, the Met Office advises staying updated on the forecast, as the exact areas of heaviest rainfall remain uncertain. The eclipse's timing at 5.12am means early risers have the best chance, but weather conditions will ultimately determine visibility in London and across the UK.
