Deep Partial Lunar Eclipse to Darken Moon on Aug. 27–28

Earth’s atmosphere will bend sunlight into the planet’s shadow and cast a reddish glow on the portion of the Moon that enters the umbra.

Overview

  • The partial lunar eclipse will span the night of Aug. 27 into the early hours of Aug. 28 and will be visible across most of North and South America and parts of Europe and Africa.
  • Observers in the British Isles should watch in the early hours of Friday, Aug. 28, with penumbral entry around 02:33, the partial phase starting near 03:33, maximum at about 05:12, and the event ending around 06:51 though the Moon may set before the finish.
  • NASA estimates that roughly 90–93% of the Moon’s diameter will be inside Earth’s dark umbra at maximum, producing a dramatic darkening with a reddish or copper tint along the shadowed edge.
  • A lunar eclipse is safe to view with the naked eye unlike a solar eclipse; viewers should use a high, clear south‑western horizon in the UK or an unobstructed western view in South Africa and the Americas and consider binoculars or a small telescope for more detail.
  • This event follows the Aug. 12 solar eclipse and illustrates the common two‑week pairing of solar and lunar eclipses, and recent coverage has added precise local timings and practical viewing advice to earlier notices.
