A partial lunar eclipse will be visible in Northern Ireland early on Friday morning, 28 August, as the Moon passes into Earth's shadow. At its peak, around 93% of the Moon's diameter will be covered, making it appear close to a total eclipse.
The first phase of the eclipse starts at 02:23 BST when the Moon enters the penumbra, the lighter outer part of Earth's shadow. The more noticeable stage begins at 03:33 BST as Earth's darker central shadow, the umbra, moves across the lunar surface. Maximum eclipse is expected at 05:12 BST.
During the event, some sunlight will pass through Earth's atmosphere and reach the Moon, potentially causing it to turn a reddish colour. Terry Moseley from the Irish Astronomical Association stated that this is sometimes called a "blood moon" and can range from orange to deep red, with the most spectacular colour near the eclipse's centre.
For viewers in Northern Ireland, challenges may include the early start, potential cloud cover, and the Moon's low position in the western sky. Visibility will depend on having an unobstructed view towards the west, as buildings, hills, or trees could block the view as the Moon descends towards dawn. Unlike a solar eclipse, no protective glasses or special equipment are needed to watch a lunar eclipse, though binoculars or telescopes could enhance the view of changing colours.
