But, in addition, in 2028 there will be another, this annular type, equally exceptional. It will undoubtedly be the ‘decade of solar eclipses‘for our country.

The first, on August 2026, will be visible along a 290-kilometre-wide strip that could include cities such as A Coruña, Gijón, Oviedo, Santander, Valladolid, Vitoria, Zaragoza, Valencia, Castellón, Tarragona and the Balearic Islands.
