The total solar eclipse of August 12, 2026 will be one of the year’s most significant sky events. Current maps published by the European Space Agency (ESA) show the path of totality crossing northern Russia, Greenland, Iceland, the Atlantic Ocean, Spain and a small northwestern corner of Portugal. A much wider region outside the path will experience a partial solar eclipse.
Where will totality be visible?
ESA’s global map places eastern Greenland, western Iceland, the northern half of Spain and the northwestern tip of Portugal inside the path of totality. Much of the rest of Europe, a large part of Canada, northern areas of the United States and sections of northwestern Africa will remain within the partial-eclipse zone. What observers see will depend on whether their location is inside or outside the narrow totality band.
In many parts of western Europe and Africa, the Sun will set while the eclipse is still in progress. Because the event will be low on the horizon, buildings, hills and cloud layers can easily obstruct the view, making an open western horizon especially important. Local start and end times vary by observation point, so location-based maps should be checked in advance.
What does the Spain totality map show?
ESA’s detailed map for Spain shows the path of totality crossing the country from west to east. The map indicates that totality may last up to about one minute and forty seconds in some locations. The duration becomes shorter farther from the center of the band, while locations outside it will not see the Sun completely covered.
What happens during totality?
Observers inside the path of totality will see the surroundings darken noticeably during the brief period when the Moon completely covers the Sun’s bright face. The corona, normally difficult to see because of the Sun’s intense brightness, will become visible around the dark lunar disk. Outside the totality path, the Moon will not completely cover the Sun and the event will remain a partial eclipse.
What eye-safety rules apply?
NASA’s safety guidance states that it is unsafe to look directly at the Sun whenever any part of the bright solar surface remains visible. Ordinary sunglasses do not provide adequate protection. During the partial phases, observers should use eclipse glasses or handheld solar viewers that meet the ISO 12312-2 standard, or use an indirect viewing method. Eye protection may be removed only during the brief total phase, when the bright face of the Sun is completely covered, and must be put back on as soon as the Sun begins to reappear.
Cameras, binoculars and telescopes need separate filters
Eclipse glasses alone should not be used while looking through a camera, binoculars or a telescope. Concentrated sunlight collected by optical equipment can pass through or damage the viewer and cause severe eye injury. NASA advises placing an appropriate solar filter over the front, Sun-facing end of the optical device. People without certified equipment can use a pinhole projector or another indirect method to cast an image of the eclipsed Sun onto a surface.
Weather will shape the viewing experience
Being inside the totality path does not guarantee a clear view. Cloud cover, horizon visibility, humidity and local weather can determine whether the eclipse is visible. Because the event will occur close to sunset in Spain and Portugal, a location with an unobstructed western horizon may be especially important. Travelers should also consider road congestion, backup routes and the latest weather forecast before choosing an observation site.
An official broadcast for remote viewers
NASA has announced a live broadcast featuring views from locations along the eclipse path and interviews with experts. People who cannot travel to the path, or whose local weather prevents viewing, will be able to follow the event through the official stream. Broadcast details should be checked again through NASA’s official channels as the date approaches.
The August 12, 2026 eclipse will be important for scientific observations and public interest in astronomy. A safe experience requires proper eye protection, suitable optical filters, verified location information and an up-to-date weather plan. Observation plans should be checked again shortly before the event.
