When does a solar eclipse occur?
According to astronomers, the total eclipses of the Sun are the greatest spectacles of astronomy.
The phenomenon occurs when the Moon passes between the Earth and the Sun. It will be visualized in its entirety in a strip that will travel, from west to east, which will travel through Argentina and Chile in 2019.
What is the strip of totality and where will it transit?
Unlike the lunar eclipses, which are visible from the entire hemisphere of the Earth, in a total solar eclipse the shadow of the Moon traces a narrow path, called totality.
Thus, the maximum percentage of the Sun that will be hidden by the Moon will depend on the place from which we observe it. That way, it will decrease as we move away from the strip of totality, which is approximately 200 kilometers. Furthermore, it will be a partial eclipse in the rest of the national territory.
It will be displayed in its entirety in a 200km wide strip that will travel 11,252 kilometers from West to East. The eclipse begin on the morning of July 2 in the South Pacific Ocean, east of New Zealand and will move northeast.
Then it will take southeast direction and at dusk it will touch land in Chile and end in the Río de la Plata.
In what places will it be visible?
This solar eclipse can be seen in different places of Argentina, in a total way in a belt that runs, from west to east, the following areas: the center of the provinces of San Juan, south of La Rioja, north of San Luis, center of Córdoba, south of Santa Fe, north of Buenos Aires.
The localities where the eclipse will occur are: Rodeo and Jachal, in San Juan and north of the Great San Juan; Chepes in La Rioja. Also, in Merlo, San Luis, Villa Dolores, Río Cuarto, Gral. Deheza, Gral Cabrera and La Carlota, in the province of Córdoba.
In addition, you will be able to watch the solar eclipse of July 2 in Venado Tuerto and Murphy in Santa Fe; Junín, Chivilcoy, Pergaminio, Rojas, Chacabuco, Bragado, Mercedes and Luján in the province of Buenos Aires.
When will we see the next total solar eclipse?
After the total solar eclipse of this year, the next one will happen on December 14, 2020. There will be another one in Argentina and Chile, but in the further south, that is to say in Patagonia.
They occur approximately every 18 months. But it is rare that it can be observed twice in a row in the same country. It will happen in Argentina in 2019 and 2020. The next opportunity to observe it in our country will only occur in 2048.
How to avoid eye damage if you wish to observe the eclipse of July 2?
In recent days both the government and the Argentine and Chilean companies have intensified their information campaign to prevent risks.
It is very important to see the eclipse in the right way. The wrong way is to try to look at it with the naked eye.
The eyes are very sensitive. The lens is a small magnifying glass, that if one looks at the sun. If one stares at the sun for a few seconds, one can remain with the eye with some injury.
The safe way is with special glasses, that the only thing that one can see with those glasses is the sun. If you put them on and look, you will not see anything.
