8/13/2026, 8:12:52 AM
Core Event
On August 12, 2026 the Moon’s shadow swept from the Arctic across Greenland, Iceland, northern Spain and a corner of Portugal, producing a total solar eclipse. The partial phase began at 15:34 UTC, totality started at 16:58 UTC, peaked at 17:46 UTC (2 min 18 s near the Denmark Strait), and ended at 18:34 UTC. In Spain totality arrived around 18:27 UTC and lasted up to 1 min 50 s; Reykjavík saw roughly 1 min of totality.
Background & Context
A solar eclipse occurs when the Moon blocks the Sun, casting its umbra on Earth. The last total eclipse visible from mainland Spain was on August 30 1905; the most recent U.S. total eclipse was on April 8 2024. The next U.S.-visible total eclipse will be on March 30 2033 (Alaska only).
Data & Statistics
| Region | Maximum Obscuration | Notes |
|---|---|---|
| Greenland/Denmark Strait | 100 % (2 min 18 s) | Longest totality |
| Spain (central line) | 100 % (?1 min 50 s) | Sunset-side viewing |
| Lisbon (Portugal) | 70–80 % | Partial only |
| London (UK) | 91 % | Deep partial |
| Paris (France) | 92 % | Deep partial |
| New York City (USA) | 9 % | Shallow partial |
| Anchorage (Alaska) | 28 % | Partial, 7:36 a.m. local start |
| Fairbanks (Alaska) | 37 % | Partial, 7:36 a.m. local start |
| Bangor (Maine) | 24 % | Partial, 1:53 p.m. local peak |
Tourism officials estimated ? 450,000 extra visitors to Spain, projecting a net economic contribution of €347 million (? $400 million).
Official Statements & Responses
- NASA recommends certified eclipse glasses meeting ISO 12312-2 for the partial phase; only totality is safe without filters.
- ESA announced a live broadcast from the Observatorio Astrofísico de Javalambre (Teruel, Spain) at 1:30 p.m. EDT, hosted by Dr Maggie Aderin-Poole with contributions from ESA Director of Science Carole Mundell.
- Spain’s Ministry of Transport and Sustainable Mobility issued safety protocols emphasizing certified glasses and warned of counterfeit products.
- Spanish officials highlighted the need for “dedicated observation points” and reinforced emergency services for the expected 1.5 million extra road journeys.
On-the-Ground Reports
Hundreds of thousands gathered in León, Zaragoza and Valencia; spectators described the “eerie daytime darkness” and bright solar corona. Reykjavík residents experienced the first total eclipse since 1433, though short daylight limited nighttime meteor observations. Balloon teams in Iceland and Spain reported clear skies, while cloud cover threatened parts of the Arctic path.
Conflicting Reports & Gaps
- Totality duration in Spain – Sources cite both 1 min 50 s and 110 s for specific sites.
- Partial-phase coverage for Madrid – Reports list 99 % and 99.9 % obscuration.
- Cloud-cover forecasts – Icelandic agencies warned of clouds over the Westfjords, but post-event data are unavailable.
What’s Next
- August 2 2027 – Total eclipse crossing southern Spain, North Africa and the Middle East, lasting up to 6 min 23 s.
- March 30 2033 – Totality over Alaska, the next U.S.-visible total eclipse.
The August 12 2026 eclipse combined a brief but scientifically valuable totality with a continent-wide partial view, driving research initiatives and a surge in eclipse tourism.
