August 12 2026 Solar Eclipse: Viewing Guidance and Regional Impacts
8/1/2026, 11:03:18 AM
Core Event – Partial Eclipse Across the UK and Total Eclipse in Europe
On August 12 a solar eclipse will be visible across much of the Western world. In the United Kingdom the Moon will cover up to 95 % of the Sun in Cornwall and the Isles of Scilly, with about 90 % obscuration in Devon, Somerset, Bristol, Gloucestershire and Wiltshire. The eclipse will begin at 18:17 BST, reach maximum at 19:12 BST and finish at 20:06 BST. The path of totality will miss the UK, passing over northern Russia, Greenland, Iceland, northern Spain and a small corner of Portugal, where observers will experience a total eclipse. In the United States and Canada the partial eclipse will range from 60 % to 20 % coverage in the late afternoon.
Background & Context
The United Kingdom last saw a total solar eclipse in August 1999. The Royal Museums Greenwich notes that the next full-solar eclipse visible from the UK is not expected until September 2090. The August 12 event is therefore the most dramatic partial eclipse for the UK in nearly three decades.
Data & Statistics
- Coverage: 95 % (Cornwall, Isles of Scilly); ? 90 % (rest of West Country).
- Timing (UK): Start 18:17 BST; Maximum 19:12 BST; End 20:06 BST.
- US/Canada partial: 60 %–20 % coverage in the late afternoon.
- Viewing spots: Bristol Downs Sea Walls Viewpoint, Clifton; Warminster Town Park (Wiltshire); Cleeve Hill (Gloucestershire); Lowery Cross Car Park (Plymouth); St Mary’s Island (Isles of Scilly).
Official Statements & Responses
The Royal Museums Greenwich provides the UK timing and emphasizes the need for a clear western horizon. The Royal Observatory Greenwich advises the use of ISO 12312-2-certified eclipse glasses and warns that sunglasses are unsafe. Bath Astronomers’ chair Simon Holbeche adds that “the only other criteria is a good view all the way to the horizon looking West.” The Bristol Astronomical Society, together with We The Curious and the Friends of the Downs, will distribute free safety-certified glasses at the Downs Sea Walls Viewpoint from 17:00 on August 12.
On-the-Ground Reports
Local astronomy clubs across the West Country have compiled recommended viewing locations, emphasizing elevated sites with unobstructed western views. Bath Astronomers suggest scouting a spot in advance and using an outstretched hand to gauge the Sun’s position at the start and end of the partial eclipse. Photographers are advised to place eclipse glasses over a smartphone camera lens for basic imaging, while DSLR users should attach a dedicated solar filter to the front of the lens.
Conflicting Reports & Gaps
Coverage estimates vary: BBC sources cite up to 95 % in Cornwall and 90 % elsewhere, while the Royal Observatory Greenwich describes “over 90 %” across the region. No source provides a definitive cloud-cover forecast for the evening of August 12, leaving weather conditions as an open variable.
What’s Next
- Perseid meteor shower: peaks on the night of August 12–13, offering up to 100 meteors per hour under dark skies.
- Partial lunar eclipse: deep partial eclipse on August 27–28, with about 96 % of the Moon entering Earth’s umbra.
These coordinated efforts aim to maximize safe public participation while acknowledging environmental and atmospheric uncertainties.
