It's the turn of South America to enjoy the spectacle of a total solar eclipse. "Clouds will likely spoil the partial eclipse for those in southern Paraguay, southern Brazil, far northern and southern Argentina and southern Chile", the firm says.
In this phenomenon the moon passes directly in front of the sun thereby blocking the visible disk of the sun from the earth and casting a shadow on it.
Here's a comparison of today's solar eclipse and the one in 2024.
A total solar eclipse happens once every 18 months when the Moon and the Sun cross paths.
The crown is the sun's outer atmosphere, stretching millions of miles into space.
Today, July 2, 2019, there's a total solar eclipse in parts of South America, but you can't see it in the U.S. So how much longer will you have to wait until you can see an eclipse in the United States again? Meanwhile, astronomers in Buenos Aires province planned to offer yoga and meditation classes during the eclipse, which will also be partially visible in other South American countries.
But totality only lasts from a few seconds to a few minutes, so it's easy to be caught off guard.
The umbra then reaches across to the coast of Chile, near La Serena, arriving at 16:38 local time (20:38 GMT).
In Junin, Argentina, totality is expected to begin around 5:42pm local time (20:42 GMT) and end at 5:44pm (20:44 GMT). Only from Chile and Argentina people will be able to see the total solar eclipse. Gazing into the Sun can damage the eyes.
How to watch the solar eclipse?
Millions of people in the USA were able to witness the last total solar eclipse on August 21, 2017.
According to Accuweather, areas in the path of totality will be able to view the eclipse with minimal obstruction as the likelihood of clouds spoiling the experience is very little.
But this eclipse won't be easy to spot as the 2017 eclipse, which moved diagonally from west to east across North America.
"The July 2nd eclipse is the first total solar eclipse since the transcontinental total solar eclipse in summer of 2017", said Paige Godfrey in a statement, astrophysicist at the Slooh Community Observatory which has a location in Chile."That was nearly two years ago now, and people are still talking about it as the greatest celestial event of their lifetimes".
