August 12 2026 Solar Eclipse: Global Visibility and Safety Guidance
8/9/2026, 1:46:59 AM
Core Event – Timing and Path of Totality
On August 12 2026 the Moon’s shadow will sweep a narrow corridor across eastern Greenland, western Iceland and northern Spain, delivering up to 2 minutes 18 seconds of total darkness. The partial phase begins around 15:37 UTC, peaks at 17:46 UTC, and ends near 19:52 UTC. Outside the corridor, much of Europe, North America, northern Africa and parts of Russia will see a partial eclipse, with obscuration ranging from a few percent to over 90 %.
Regional Visibility – Percent Coverage by Location
| Region | City | Max coverage | Local time* |
|---|---|---|---|
| U.S. (partial) | Fairbanks, AK | 37 % | 8:27 a.m. AKDT |
| Boston, MA | 16 % | 1:55 p.m. EDT | |
| Canada (partial) | Iqaluit, NU | 61 % | 1:24 p.m. EDT |
| Europe (partial) | London | 91 % | 7:13 p.m. BST |
| Paris | 92 % | 8:17 p.m. CEST | |
| Europe (total) | Reykjavík, Iceland | up to 2 min totality | 5:48 p.m. GMT |
| León, Spain | ~1 min 45 s totality | 8:32 p.m. CEST |
\*Local times are approximate.
Alaska and New England receive the deepest U.S. coverage; most of the continental United States sees less than 20 % obscuration.
Safety Recommendations – Protecting Eyes During the Partial Phase
- Use ISO 12312-2-certified eclipse glasses that are free of scratches.
- Indirect viewing—pinhole projectors, colanders, or projection onto white paper—is a safe alternative.
- The Royal College of Ophthalmologists warns that retinal injury can occur without pain, even when the Sun appears dimmer.
Official Statements & Responses
- Jess Lee, astronomer at the Royal Observatory Greenwich, calls the coverage “still impressive.”
- Tom Morgan, Met Office meteorologist, expects “reasonable viewing conditions” for summer.
- Catherine Heymans, Astronomer Royal for Scotland, stresses cloud forecasts are key and advises a “dress rehearsal” to test sightlines.
- NASA will webcast the total phase for viewers outside the path of totality.
Conflicting Reports & Gaps
Coverage percentages for several European cities differ slightly between sources. London is listed at 91 % by both Astronomy.com and WION; Paris shows 92 % in each. Barcelona’s figures vary by a few tenths of a percent, reflecting rounding differences. No official clarification has been issued, so observers should consult local societies for the most precise data.
Verbatim Quote
- “I’d recommend a dress rehearsal in the days before. If you can’t see the sun from your planned viewing spot at 7.30 pm because your view is blocked, then you’ll want to find a different location for the real event,” — Catherine Heymans
What’s Next – Future Eclipse Opportunities
- A partial eclipse later in 2027 will affect Newfoundland.
- An annular eclipse is expected in 2028 across northern South America, with a small partial view in the eastern U.S. and Canada.
- A large partial eclipse will occur in 2029, covering most of North America with up to 81 % obscuration in northern Canada.
- June 12 2029 brings a 34 % partial eclipse over northern Canada at sunrise.
- The Perseid meteor shower peaks on the night of August 13 2026, offering a backdrop after the eclipse.
Observers should verify local weather forecasts, obtain certified glasses, and consider travel to high-coverage locations such as Iceland, Spain or northern Canada for the most dramatic experience.
