A total solar eclipse will occur on August 12, 2026, tracking across the Arctic, Greenland, Iceland, and northern Spain. According to NASA, this event is notable for its path over land and its timing during sunset in parts of Europe, offering a rare opportunity for observers to witness the celestial alignment near the horizon.
Path of the August 2026 Total Solar Eclipse
The 2026 total solar eclipse begins in the Arctic, crossing through Greenland and Iceland before moving across the Atlantic Ocean toward Europe. The path of totality concludes in northern Spain, where the sun will be low on the horizon. Because the eclipse reaches the Iberian Peninsula late in the day, viewers in Spain will experience the phenomenon during sunset.
While the total eclipse is restricted to a narrow track, a partial solar eclipse will be visible across much of Europe, northern Africa, and parts of North America. In North America, the visibility is limited; only the extreme northern regions, including parts of Alaska, will experience a partial eclipse. For the contiguous United States, the event is largely out of view, with only minor coverage possible in northernmost latitudes.
Why Sunset Eclipses Are Rare
A solar eclipse occurs when the moon passes between the Earth and the sun, casting a shadow on the planet. Most eclipses occur during the middle of the day when the sun is at its highest point. A sunset eclipse requires a precise alignment of the moon’s shadow with the Earth’s rotation at the exact moment the sun dips toward the horizon.
According to NASA’s eclipse archives, the rarity of this event is compounded by the moon’s shadow frequently falling over uninhabited regions or vast expanses of the ocean. The 2026 event is distinct because the path of totality crosses populated areas in Europe, allowing millions to potentially view the phenomenon. Previous notable sunset eclipses occurred in 2019, when observers in Chile and Argentina experienced totality at sunset, and in 2014, when a partial sunset eclipse was visible in parts of North America.
Essential Safety Protocols for Viewing
Direct observation of the sun during any eclipse—total or partial—requires specialized equipment to prevent permanent eye damage. The sun’s intense radiation can burn the retina even when the moon obscures a significant portion of the solar disk.
- Standard sunglasses, even those with dark tints, do not provide adequate protection.
- Inspection: Before use, viewers should check their eclipse glasses for any scratches, punctures, or tears. If the filters are damaged, they should be discarded.
- Indirect Methods: If eclipse glasses are unavailable, observers can use pinhole projectors to cast an image of the sun onto a surface, avoiding the need to look directly at the sky.
- Optical Devices: Cameras, binoculars, and telescopes require specialized solar filters mounted to the front of the lens. Looking through an unfiltered optical device at the sun can cause instantaneous and severe eye injury.
Summary of Visibility
The August 12, 2026, eclipse serves as a significant astronomical event for European observers. While North American visibility will be negligible, the path across Greenland, Iceland, and Spain provides a rare chance to witness a total solar eclipse at sunset. For those planning to observe the event, authorities emphasize the necessity of certified solar filters to ensure safe viewing throughout the duration of the eclipse.
