On August 12, 2026, a total solar eclipse will sweep across parts of Greenland, Iceland, northern Russia, Spain, parts of Portugal, and the Atlantic Ocean. This rare celestial event marks the first time a total solar eclipse will be visible in Europe since 1999. According to NASA, a total solar eclipse occurs when the moon moves between the sun and Earth, casting a shadow that fully blocks the sun’s face.
The “Sunset Eclipse” Phenomenon
The 2026 event is particularly notable for its unique geometry. In parts of Spain, the eclipse will occur just before sunset, creating a “sunset eclipse.” In the Balearic Islands, for instance, the sun will be eclipsed while positioned less than three degrees above the horizon. This creates a distinct atmospheric effect where the natural process of sunset overlaps with the moon’s shadow. As the moon’s shadow approaches, daylight will collapse more rapidly than during a standard sunset, potentially resulting in a darker twilight and an interruption to the sun’s usual afterglow. Observers at the very end of the eclipse path may even witness the moon’s shadow lifting off the planet, a sight Dr. Tyler Nordgren describes as a rare opportunity to see the shadow depart the Earth’s surface.
Viewing From the United States and Beyond
While the total eclipse is limited to specific regions, North America will experience a partial solar eclipse. From Alaska to North Carolina, and across parts of Canada, viewers will see what appears to be a “bite” taken out of the sun. Unlike those in the path of totality, North American observers will not see the sun completely blacked out, and they must use specialized eye protection throughout the entire event. NASA emphasizes that eclipse glasses must be used to view the sun during a partial eclipse to avoid permanent eye damage.
Strategic Planning for Totality
For those traveling to see the total eclipse in Spain, geography is critical. Major cities like Madrid and Barcelona will experience a near miss, with Madrid reaching a 99.96% partial eclipse, which falls short of the conditions required to see the solar corona or the dramatic drop in temperature associated with totality. Experts recommend that observers prioritize locations with clear, unobstructed western horizons, such as coastal beaches, riverbanks, or elevated parks. Cities such as Valladolid, Palencia, León, Zaragoza, and Burgos are cited as prime locations for viewing. Because this is a low-sun event, visibility is highly dependent on local weather and the absence of obstructions like buildings or trees.

A Celestial Bonus: The Perseids
The eclipse event is followed by an additional astronomical treat. The night after the eclipse, the Perseid meteor shower—considered the best meteor shower of the year by NASA—will peak. Because the shower coincides with the new moon, conditions for viewing the meteors are expected to be optimal. Observers planning to track the eclipse are encouraged to use professional resources, such as interactive maps from the Instituto Geográfico Nacional or Xavier Jubier, to verify specific sight lines. However, as the event approaches, on-site scouting to ensure a clear view of the horizon remains the most reliable method for witnessing this rare “collector’s item” of an eclipse.
