The solar eclipse this Tuesday will be partial in Spain and will only be seen in the northeast

During the morning of this Tuesday, October 25, it will be possible to see a solar eclipse in much of Europe, northeast Africa and western Asia. In Spain it will be partial and of very low magnitude, visible in the peninsular northeast.

The phenomenon will begin in the Atlantic Ocean, near the coast of Iceland, and will end in the Indian Ocean, according to data from the National Astronomical Observatory (OAN) website.

In total, it will last 244 minutes, just over four hours, and its maximum will be north of Nizhnevartovsk, Russia, where 86% of the solar disk will be hidden. In Spain, being partial, the Moon will cover 12% of the solar diameter in Gerona, where it will be seen in its greatest magnitude, 10% in Barcelona and below that figure in the rest of Catalonia, Aragon, Navarra, Euskadi, La Rioja, Cantabria, Asturias, north of Castilla y León, north of the Valencian Community and the Balearic Islands.

In Barcelona, ​​the eclipse is expected to begin at 11:33 a.m. and the maximum will occur at 12:07 p.m. –the moment in which the magnitude will be 0.10, since the Moon will cover 10% of the solar diameter– and will end at 12:42 p.m., with a duration of 69 minutes. The OAN has enabled a map to check the schedules and the evolution of the phenomenon in the provincial capitals.

In an eclipse, one astronomical object hides another. From Earth, we can see eclipses of the Sun, when the Moon hides the solar disk, and of the Moon, when the opposite happens and the star stands in the shadow that the Earth projects in space. The last partial solar eclipse in Spain was on June 10, 2021. The phenomenon can be seen partially with some frequency, while witnessing a total or annular eclipse is much more difficult. In fact, the last visible annular eclipse took place in 2005, and the last total eclipse was in 1959, and only from the Canary Islands; The Iberian Peninsula has not seen a total solar eclipse since 1912.

According to data from the National Astronomical Observatory (OAN), this eclipse drought is about to end because between 2026 and 2028 there will be two total eclipses and one annular one that will be visible from some point in the country. The next total solar eclipse visible in Spain will take place on August 12, 2026, followed by another on August 2 of the following year, and shortly after, on January 26, 2028, we will see an annular eclipse in Spain.

safe observation

To observe these phenomena, experts warn that you should never look directly at the Sun or use sunglasses or home remedies such as X-rays, blurred films, or cameras or telescopes or binoculars that are not equipped with solar filters. During a partial eclipse, the Sun is never completely covered by the Moon and therefore looking at it without safe and adequate protection can damage the eyes, just as it would on any day without an eclipse.

You can use approved filters commonly called eclipse glasses, or see your image projected on some type of screen located in the shade. According to the OAN, the simplest and safest method of observing an eclipse is by projection, with two pieces of cardboard and in a window, standing with your back to the sun. You just have to make a hole of a few millimeters in the center of a piece of cardboard (it does not have to be circular) and then place the other one just in front so that the light passes through the hole in the first one and is projected onto the surface. second.
