The first partial solar eclipse is already a reality. At 4:46 p.m., it began in the South Pacific region and part of Antarctica. As the minutes passed, it began to be observed on the continent, more precisely in Puerto Natales, Chile and Santa Cruz, Argentina.
Solar eclipses occur when the new moon passes in front of the face of the sun from Earth’s perspective. Partial solar eclipses occur when the moon blocks only part of the sun’s disk. It often seems that the moon has “bitten” or taken a piece of our star.
In this case, about 64% of the solar disk It will be hidden at most, according to NASA. In the City of Buenos Aires, the maximum concealment will be 25%, while, for example, further south, in Bariloche, you can see up to 51% of the hidden sun. In Ushuaia it will be 52%, in Calafate 50%, in Neuquén 36%, in Mendoza 27% and in Salta 12%.
The percentage will vary depending on the location of the display. The greatest magnitude will be approximately in South America and the surrounding ocean, according to timeanddate.com, a site that will also follow the event live through a live blog. Also, the YouTube channel Gyaan ki gareebi Live will start a broadcast when the eclipse begins.
More precise time and place to observe it
The Moon it will pass in front of the edge of the Sun and will only be visible from Argentina, Chile, Uruguay, southern Peru and Bolivia, western Paraguay and a small region of Brazil. Although the area with the highest visibility for this event will be over the Pacific Ocean, between Antarctica and South America.
As to the duration of the eclipse, the maximum appreciation of the sun will be 7 minutes, because the concealment process lasts very little. That is to say that, after starting around 5:30 p.m., the moment where the sun will be seen “half” will take place around 6:10 p.m.
“It will be visible from almost the entire Argentine Republic, but the most favored region will be the south-west. From Buenos Aires it will be visible from 5:45 p.m. until sunset.he explained to Infobae Constantino Baikouzis, astronomical researcher and director of the Parque Astronomico de la Matanza program.
Despite the emotion that can arise from an event of this magnitude, experts warn that this phenomenon should not be observed without adequate protection elements, such as glasses with special filters.
“It can cause burns to the retina, tissue in which images are processed and then transmitted to the brain. These injuries can range from mild to severe and can even lead to permanent blindness,” Dr. Laura Taverna, an INEBA ophthalmologist, told Infobae.
While, Rogelio Ribes-Escuderoan ophthalmologist from the Ophthalmology Service of the German Hospital, added: “The cornea and the lens are two lenses. Therefore, if you look directly at sunlight, there will be damage to the macula (center of the retina), which leads to irreversible damage.”.
Unlike what happens with total solar eclipses, in which the Moon completely covers the solar disk and the observer can take off his glasses for a few seconds, In partial eclipses like today’s, protective glasses can never be removed.
In the event that you have a telescope or binoculars and that they do not have a filter for this event, a piece of advice from the experts is to seek that the sunlight passes through them and is projected on a smooth surface. In this way, although it will not be observed directly, it will be possible to appreciate not only the eclipse, but to some more specific details. If you don’t have the right accessories, you can make a homemade projector.
It is worth noting that for telescopes it is recommended to use “low magnification lenses as they produce larger images and generate less heat, thus protecting the instrument”, they advise from the Osiris Astronomical Group, based in Patagonia.
