The next phenomenon of this magnitude, in this region, will only happen in 2103.
When the Earth and the Sun align and the Moon is in the middle of the two, a solar eclipse occurs. It can be of three types: total (when the moon totally covers the sunlight), partial (only part of the illumination is covered by the Moon) and annular, when the distance between the stars causes the Moon to stop in front of the Sun, but covering only the center, thus forming a ring of light around the shadow of the Moon that covers the Sun. Confused? The gif below gives a little help.
Although they are curious phenomena – which can "turn the day into night" for a few minutes – they are not rare: total solar eclipses, for example, occur every 18 months.
However, what makes the observation of the brief disappearance of the Sun so exciting is that it is only visible to those directly on the path of the so-called moon umbra, that is, the darkest part of the shadow from which the entire disk of the sun is obscured.
The total territory capable of being inside "umbra" to each eclipse is not very big – they are areas between 150 kilometers and 250 kilometers in length that can see the phenomenon at a time. Only a small percentage of the Earth-illuminated hemisphere is able to enjoy the live experience.
In addition, watching one in real time is a genuinely unique opportunity in life. After all, although they are not uncommon, total solar eclipses occur at the same specific location, on average, every 360 years.
On August 21, 2017, thousands of people from around the world witnessed the "Great American Solar Eclipse," the first total solar eclipse seen in the United States since January 11, 1880.
Now it's our turn: July 2 will be the "Great South American Solar Eclipse", since the narrow path of the eclipse will extend through the South Pacific, starting in La Serena, Chile, and closing in Buenos Aires, Argentina . Only these two countries will be able to get the full view of the eclipse – but a partial eclipse will also be visible in Uruguay, Paraguay, Ecuador and Brazil. In this interactive map, you can see the whole region where the eclipse will appear.
Another advantage is that two large observatories – the Inter-American Observatory of Cerro Tololo and the Observatory of La Silla – are directly in the way of the umbra. The powerful telescopes, positioned in the remote areas known for their clear skies in Chile, will capture the stunning phenomenon live and transmit it to hundreds of countries and millions of people around the world.
Here in Tupiniquins lands, almost the whole country can see pieces of the eclipse – depending on the city, we can see from 9% to 60% of sun concealment. The Northeast will be the only region that will not be able to see the phenomenon, because the eclipse will begin at a time when it will be dark in the region.
In Brazil, the show begins in some cities around 4 pm, with the peak of the eclipse happening at 5:49 pm Brasília time. In this site you can search how the eclipse will appear in your city (just put your city in the search field that says "place or country …").
If you are among the lucky few on the road to the "Great South American Solar Eclipse," use special eyeglasses to protect the eyes from ultraviolet radiation, which can result in permanent damage – and even blindness.
For those who are not in the path of the solar eclipse, a consolation: between July 16 and July 17, 2019, a large part of the world – including South America, Europe, Africa, Asia and Australia – will see a partial lunar eclipse , or a spectacular "moon of blood". The way it will be to settle for this, because another solar eclipse of the magnitude of day 2 will only happen again in 2103.
