Rare Total Solar Eclipse To Plunge Northern Spain Into Darkness In August.

 

A rare total solar eclipse will sweep across northern Spain on 12 August, briefly turning daylight into darkness as the Moon completely blocks the Sun in the first total solar eclipse visible from mainland Europe since 2006.The spectacular astronomical event occurs when the Moon moves directly between the Sun and Earth, casting a narrow shadow across the planet. During the brief period of totality, daylight fades into twilight, temperatures can drop, shadows take on unusual shapes and some animals may respond as though night has arrived.

Why the Eclipse Happens

According to NASA, the event is possible because of a remarkable cosmic coincidence. Although the Sun is around 400 times larger than the Moon, it is also approximately 400 times farther away from Earth, causing both objects to appear almost the same size in the sky.

This alignment allows the Moon to completely cover the Sun’s surface, revealing the Sun’s outer atmosphere, known as the corona, which is normally hidden by the brightness of the solar surface.

The eclipse will begin over a remote area of northern Russia before the path of totality moves across Greenland, Iceland, Spain and the north-eastern tip of Portugal.

In Spain, the shadow will pass roughly from the northern city of Oviedo to the island of Mallorca.

Less Than Two Minutes of Darkness in Spain

Observers across Spain will experience less than two minutes of total darkness shortly before sunset.

In Burgos, totality is expected to last around one minute and 48 seconds. The eclipse will continue for slightly longer in parts of Russia and Greenland, although the period of complete darkness will remain below two-and-a-half minutes.

Before and after totality, a partial eclipse will be visible for approximately one hour and 45 minutes.

The partial phases will also be visible across large parts of Europe, Canada, the northern United States and north-west Africa.

Rare Event for Any Location

Although one or two solar eclipses occur somewhere on Earth every year, total solar eclipses are far less common for individual locations because the Moon’s shadow falls across only a small area of the planet.

As a result, some regions may wait hundreds of years before seeing another total eclipse.

However, Spain will have another opportunity to witness a major eclipse soon. On 2 August 2027, a total solar eclipse will cross southern Spain, northern Africa and the Arabian Peninsula.

The event has been dubbed by some observers as the “eclipse of the century” because totality is expected to last six minutes and 23 seconds — the longest total solar eclipse of the 21st century.

Spain is also set to experience an annular solar eclipse, known as a “ring of fire” eclipse, on 26 January 2028. During that event, the Moon will cover the centre of the Sun while leaving a bright ring of sunlight visible around its edges.

Safety Warning for Eclipse Viewers

Experts have warned that people should never look directly at the Sun during any stage of a solar eclipse without suitable eye protection.

Specialist eclipse glasses that meet the ISO 12312-2:2015 international safety standard are recommended because they block harmful ultraviolet rays and protect against permanent eye damage.

Health experts have also highlighted that the human eye does not contain pain receptors, meaning serious damage may occur without immediate warning signs.

Research following the 2024 total solar eclipse in the United States found a significant increase in online searches for eye discomfort after the event, reinforcing warnings about the importance of proper protection.

As millions of skywatchers prepare for the August spectacle, astronomers are urging viewers to enjoy the rare event safely and responsibly.
