Overview
- The UK will see a very deep partial eclipse on Wednesday 12 August 2026 with the Moon covering roughly 89% to 96% of the Sun depending on location.
- Regional timings place the partial eclipse starting in the early evening, peaking around 7:10–7:15 pm BST, and ending near 8:10 pm BST with Cornwall and the Isles of Scilly seeing the greatest obscuration.
- Royal Museums Greenwich and the UK Health Security Agency warn never to look directly at the Sun and advise ISO 12312-2 certified eclipse glasses or indirect methods and front-mounted solar filters for cameras and telescopes.
- Best views require a clear western horizon so elevated or coastal sites in south‑west England are recommended, and observers should plan for weather, horizon obstructions, and local sunset angles.
- Hours after the eclipse the Perseid meteor shower peaks overnight on 12–13 August and a 90% partial lunar eclipse follows on 28 August, increasing demand for dark viewing sites and public interest in back‑to‑back sky events.
