Astronomers and skywatchers anticipate the total solar eclipse on August 12, 2026, which will trace a path of totality across Spain, Iceland, Greenland, and northern Russia. While South America will not experience the event, NASA and the European Space Agency will stream live coverage online for viewers worldwide.
The celestial alignment arrives on Wednesday, August 12, 2026, bringing a total solar eclipse to the Northern Hemisphere. The Moon will pass directly between the Earth and the Sun, casting a shadow along a narrow path of totality that sweeps across the Atlantic Ocean, Greenland, Iceland, northern Russia, Spain, and a small corner of Portugal, as confirmed by space agencies.
For skywatchers outside this narrow corridor, the event will appear as a partial eclipse. Portions of northern North America, much of Europe, and northwestern Africa will see a fraction of the Sun obscured. However, due to the Earth’s geometry and the trajectory of the lunar shadow, observers in Peru and the rest of South America will remain completely outside the visibility zone.
Where the Path of Totality Crosses Europe and the Arctic
The upcoming celestial event marks a historic milestone for the Iberian Peninsula.
Because Spain sits near the very end of the lunar shadow’s trajectory, the total phase will unfold right at sunset. Observers in cities positioned inside the corridor of totality will witness the Sun dip toward the western horizon during full occultation.
Astrophysicists note that cities such as León, Zaragoza, and Valencia sit firmly within the shadow corridor. In Oviedo, the partial phase begins at 7:31 p.m. local time, leading into a totality window stretching for approximately 1 minute and 48 seconds. Meanwhile, major urban centers like Madrid and Barcelona fall just outside the total shadow band, though they will experience an exceptionally deep partial eclipse with roughly 99% of the solar disk covered.
Partial Visibility Across North America and Broadcast Schedules
In the United States and Canada, the eclipse unfolds as a daytime partial event. Observers will watch the Moon take a bite out of the solar disk without experiencing daytime darkness or seeing the solar corona with the naked eye. Coverage varies significantly by region: Fairbanks, Alaska, will reach 37% occultation, while New York City records about 9% and Washington, D.C., sees just 4%.
To bridge the geographic gap for viewers in South America and non-observable regions, space agencies have organized extensive digital broadcasts. NASA’s official coverage, featuring telescopic lenses, aerial footage from research aircraft, and commentary from specialists. The European Space Agency will also stream feeds from the Javalambre Astrophysical Observatory in Spain.
Atmospheric Research and Future Eclipse Timelines
Beyond the visual spectacle, the alignment serves as a major field day for atmospheric scientists.
This event also kicks off a sequence of solar alignments for the region.
Safety Protocols for Observing Partial Phases
Public health officials emphasize that anyone viewing the partial phases must use certified eye protection. Because a sliver of the Sun remains visible outside the path of totality, looking directly at the star without proper gear risks severe, permanent retinal injury.
Specialists recommend using certified solar viewers or utilizing indirect projection methods. Standard sunglasses, makeshift home filters, and camera viewfinders do not block harmful solar radiation safely.
