In the Photos of the Readers of La Vanguardia we can see the great sunspot AR 3363, today, at sunrise, crowning the Agullola de Rupit, in Osona.
This showy eruption is larger than Earth and with a telephoto lens or binoculars it can be seen, especially this Monday with the haze, which acted as a filter.
The colorful riscal de la Agullola, with a height of 921.9 meters, is separated from the rest, the Pla de Fàbregues, which makes its peculiar shape stand out even more.
The haze is a meteorological phenomenon that occurs in the presence of Saharan dust in the atmosphere, which has already manifested itself several times this year and, now, in the midst of a heat wave.
A sunspot is a region of the sun that has a lower temperature than its surroundings and with intense magnetic activity. It 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.
