Today at dawn on Gavà beach, in Baix Llobregat, it was possible to observe the spectacular sunspots inside the sun.
A marvel, in addition, with the planes portrayed as if they were inside the king sun, as we see in The Photos of the Readers of La Vanguardia.
A sunspot is a region of the sun that has a lower temperature than its surroundings and with intense magnetic activity.
The sunspot consists of a dark central region, called the “umbra,” surrounded by a lighter “penumbra.”
A single spot can measure up to 12,000 km (almost as large as the diameter of the Earth), but a group of spots can reach 120,000 km in size or more.
