A partial lunar eclipse on 27 August will see Earth’s shadow cover most of the Moon, producing a pronounced reddish or orange appearance often associated with a “blood moon”. The event matters because it will be widely visible across the Americas without specialist eye protection, while viewing conditions in much of Europe will be less favourable.

The partial phase will last about three hours and 18 minutes, reaching a magnitude of 0.93, with roughly 93 per cent of the Moon’s diameter inside Earth’s darkest shadow at its peak. Peak viewing times include 12:14 am in New York, 11:14 pm in Chicago and Lima, and 5:12 am in London; observers are advised to seek clear, dark skies, although binoculars, telescopes and livestreams can enhance or substitute for direct viewing.
