On August 21, it will be a total solar eclipse that in the United States will be seen from coast to coast, but in Spain will be enjoyed little because it will be partial and only visible its end, which will coincide with the sunset.
In Madrid, for example, this will start at 8:45 p.m., until sundown at 9:03 p.m.; in Caceres will also begin at that time and in A Coruña at 20:43 hours and you will be able to witness a sunset with the solar disk slightly eclipsed by the moon.
In the Balearics and the eastern end of the peninsula will not be visible, according to data from the National Geographic Institute, adding that the best place in Spain to observe this partial eclipse is the Canary Islands.
A solar eclipse occurs when the moon hides the sun from the perspective of the Earth, he told EFE the director of the Planetarium of Pamplona, Javier Armentia, who stresses that the planned blackout for this solar eclipse in Spain is “very minimal”.
In Madrid, only 7.7% of the solar disk will be obscured; in A Coruña almost 13%; in Huelva a little more than 14% and in the Canary Islands it will darken between 39 and 41% of the solar surface.
Nevertheless, Armentia remembers that internet will bring the spectacle to the whole planet, among them NASA, that will relay this event that in the USA did not happen for 99 years.
There the eclipse can be seen along a stretch of over 110 kilometers wide which crosses the country from the Pacific to the Atlantic, starting from Oregon to South Carolina, where the moon completely covers the disk visible from the Sun.
Depending on the location, viewers will experience the eclipse for up to 2 minutes and 40 seconds, and the event will take an hour and a half to travel the sky from the Pacific coast, where it will begin at 10:15 am ( 17:15 GMT), to the Atlantic, at 2:45 pm (18:45 GMT).
This event will not only be retransmitted by NASA; the website sky-live.tv, in collaboration with the European project STARS4ALL, will also show this “great American eclipse”, as it has begun to be called.
A group of astronomers, including Spanish Miquel Serra, will travel to Idaho to observe and retransmit it in Spanish (the connection will take place at 16:00 GMT and can be followed through sky-live.tv).
The expedition led by Serra will also measure luminosity and temperature data during the eclipse with several instruments (TESS-W photometers) developed by the Universidad Complutense de Madrid.
“After the last eclipse in Indonesia, which was really difficult to observe by the clouds, comes the great American eclipse,” says Serra on the initiative’s website, who points out that this time the probability of clouds is low: “this united fact to which we are going to have two observation points make the eclipse the safest of the last years. “
In fact, he adds, “we had not had such a favorable eclipse since 2006, when we were watching from the desert of Libya.”
Besides a visual spectacle, it will also be a scientific opportunity: it will serve to advance in the knowledge of the complex magnetic field of the Sun and its effect on the terrestrial atmosphere.
Wherever you are and whether the total or partial eclipse is always look at this star with protection.
In addition to eclipse glasses, which can be purchased in opticians and in places linked to astronomy – stocks are exhausted in almost all suppliers approved in the US – experts advise, if binoculars are used, put filters on lens.
If telescopes are used, they must be fitted with the appropriate input filters.
The use of normal sunglasses and “home” remedies such as X-rays or veiled films is strongly discouraged.
The next important appointment for Spain will be in August 2026, where the band of totality will cross cities like A Coruña, León, Palencia, Valladolid, Zaragoza, Castellón finishing in Palma. (August 21, 2017, EFE/Practica Español)
