Solar eclipse 2020: see how the phenomenon was recorded

There was a blurry, professional, assembled photo from last year, a kpop group clip, meme – the world recorded the total solar eclipse (the last of the year) in addition to scientific reports.

The spectacle was seen by those who were in a narrow strip of 90 kilometers covering the southern coast of Chile, the Andes and Argentina, as well as part of Brazil. It is the second time, in a year and a half, that the moon’s shadow travels the region.

This year’s eclipse was special: it happened around noon, when the sun was overhead (last year’s occurred in the late afternoon; the 2021 can only be seen in full in Antarctica).

In Brazil, he was seen partially in the states of the South and Southeast (North and Northeast were left out). In Rio Grande do Sul, it was possible to see 60% of the Sun’s disc darken; in Paraná, 50%; in São Paulo and Rio de Janeiro, only 40%. Obviously, not everyone was happy about it.

What and where

Many people are still confused about the conditions for a total eclipse of the Sun: the Moon passes between the Earth and the star, casting its shadow on the planet’s surface.

The projected image of the eclipse, being partial in some places, delighted many people.

Creativity to watch

On the eve of a solar eclipse, experts recommend a series of measures, such as not looking directly at the sun and wearing appropriate equipment, such as special glasses specially made for this.

As they are expensive, ophthalmologists recommend using a welding mask glass – advice that many people followed.

But there were those who decided to improvise, using the 2 in 1 filter:

Registration in space

Every 11 years, the Sun ends one cycle of activities and begins another – which in astrophysics means a minimum and maximum solar, marked by the appearance and disappearance of sunspots. This causes the Sun to change from a relatively calm to a stormy star.

By the beginning of the measurements, the Sun officially entered its 25th cycle in December 2019 and is heading towards its peak, which will take place in July 2025.

The increase in solar activity also provided a solar eclipse as the Earth has not seen in a long time. When the Moon aligns with the star, the solar corona becomes visible to the naked eye and the more sunspots (as it is now occurring), the farther the giant flames rise.

Even in places where the sky was cloudy, it was possible to appreciate the disappearance of the Sun.

In Brazil, the bad mood of the Sun did not help the visibility of the phenomenon.

18 months

NASA and other scientific entities broadcast the passage of the Moon in front of the Sun live. One of the most beautiful images recorded was that of the National Oceanic and Atmospheric Administration (NOAA).

If you missed the show, it will happen again in 18 months (up to five eclipses per year may occur, but not total). The next passages of the Moon in front of the Sun will be seen in Antarctica and South Africa in December 2021; in Indonesia and Australia, in April 2023; in the USA and Canada, in April 2024; in southern Europe and Greenland in August 2026. and in part of North Africa and the Middle East in August 2027.
