This is the first time in decades that a total solar eclipse will cross mainland Spain and Iceland, following major eclipse events in North America in 2017 and 2024.
The narrow path of totality—where the Moon completely covers the Sun—will pass through Spain and Iceland, offering spectacular viewing experiences at key locations, such as A Coruña, Zaragoza, Valencia, Bilbao, and Reykjavik.

Madrid and Barcelona will experience a deep partial solar eclipse, with more than 99% of the Sun covered. However, by traveling to the outskirts or nearby locations that lie within the path of totality, observers can witness the full total solar eclipse.
Moreover, a partial eclipse will be visible across most major European cities, such as London, Paris, and Berlin. Even outside the path of totality, millions throughout Europe will have the chance to observe this rare phenomenon.
Regions seeing, at least, a partial eclipse: Europe, North in Asia, North/West Africa, Much of North America, Pacific, Atlantic, Arctic.

I really enjoy my Marumi filter DHG ND-100000 and its advanced successor, EXUS ND100000(5.0) for solar observation and photography. The results are very impressive. As the solar activity is increasing again, your filter becomes more and more interesting!
