August 12, 2026 Total Solar Eclipse: Where and How to Watch

On August 12, 2026, a total solar eclipse sweeps across Greenland, Iceland, northern Russia, Spain, and a small corner of Portugal, while millions across parts of North America, Europe, and Africa experience a partial eclipse. NASA and scientific agencies are streaming the event live, as astronomers and municipal authorities prepare for a massive influx of celestial observers.

The Path of Totality Across the Globe

The celestial alignment brings a total solar eclipse to remote and populated regions alike. According to NASA’s Scientific Visualization Studio data, the Moon’s inner shadow—the umbra—traces a red band crossing Greenland, Iceland, and northern Spain. In a small, remote region of northern Russia, totality occurs mid-day. For Greenland and Iceland, the Sun goes dark in the late afternoon or evening.

According to reporting from New Scientist, totality reaches Iceland’s capital of Reykjavík for just over one minute at 5:48 p.m. local time. This event marks the first total eclipse visible in Iceland since 1954, with the next one not scheduled until 2196. Following its path across the Atlantic Ocean, the total eclipse makes landfall in northern Spain just before 8:30 p.m. local time, grazing the northeastern tip of Portugal and crossing the Balearic Islands before sunset.

Partial Eclipse Views Across North America and Europe

While only a select few regions witness the full corona during totality, a broad partial eclipse blankets about a quarter of the globe. NASA confirms that northern parts of the United States—ranging from Alaska to North Carolina—along with most of Canada, much of Europe, and northwestern Africa, experience a partial solar phase.

Observers in the United Kingdom and Ireland see between 90 and 96 percent of the Sun covered by the Moon, according to New Scientist. In London, the partial phase runs from 6:17 p.m. to 8:06 p.m., peaking at 7:12 p.m. Meanwhile, North American cities experience much smaller fractional coverage. Montreal sees an 18 percent eclipse at 1:45 p.m., and New York records a 9 percent eclipse at 1:54 p.m.

Critical Safety Measures for Observers

Viewing any phase of a solar eclipse requires strict adherence to safety protocols to prevent permanent eye damage. NASA emphasizes that only during the brief moments of totality can viewers look directly at the Sun without protection. Before and after totality, and throughout the entirety of a partial eclipse, observers must utilize certified solar viewing glasses, handheld solar viewers, or safe solar filters.

For communities organizing public gatherings or viewing events, managing safety compliance and crowd logistics is paramount. Local municipalities often collaborate with public safety officials to manage traffic spikes and ensure safe viewing zones. Educational institutions and science centers also lean on specialized outreach consultants to distribute approved viewing filters and safety literature to the public.

Scientific Broadcasts and Digital Access

For those outside the visibility paths, global space agencies are providing comprehensive digital coverage. NASA provides a live broadcast starting at 1:15 p.m. EDT on August 12, allowing researchers and enthusiasts worldwide to track the Moon’s shadow as it crosses the globe.

Whether watching a sunset eclipse in western Europe or catching a partial glimpse from the northeastern United States, observers are reminded of the precise mechanics governing our solar system—and the importance of preparation when Earth, Moon, and Sun briefly align.
