This Saturday, the only total eclipse of 2021 will occur

This Saturday, the only total eclipse of 2021 will occur

This Saturday 4th December eclipse Total solar energy can be visualized in different regions of the world And for this, many followers or experts on this phenomenon are already preparing to capture the moment. Unlike a lunar eclipse, a solar eclipse is distinguished by the fact that it cannot be seen directly.

Human eyes cannot resist solar radiation, so It is necessary to use special glassesBecause the glasses that are normally used for sun protection do not work in this type of situation. A welding filter that provides proven eye protection may also be used.

National Aeronautics and Space Administration expertsNASAThey said that the total eclipse of the sun only It will be 100% visible from Antarctica. Unfortunately it cannot be seen in Cuba, although it can be seen partially in some areas of Chile, Argentina, New Zealand and Australia.

evenly, Residents of the southern tip of Africa, such as Namibia, Lesotho and South Africa, or residents of South Georgia, the South Sandwich Islands and the Crozet Islands, will also have the opportunity to partially see it.

At about 01:00 a.m. (UTC) on December 4, the solar eclipse will reach its maximum point, when the moon completely covers the sun. However, experts explained that the time when it can be seen most clearly will be at 1:33 am because the solar corona will protrude into the outer part of the solar atmosphere that is normally invisible to the human eye.

Experts remember that when The moon completely blocks sunlight, and meteorological variables often change from temperature, relative humidity, and pressure at the Earth’s surface.

The decrease is equivalent to the difference in temperature that exists between day and night at that time of year in that place.

Darkness will also bring with it a change in the atmosphere called “ecliptic winds.” In this regard, atmospheric physicist Giles Harrison said in a study published in 2016 by the University of Reading (UK) that “As the sun disappears behind the moon, the Earth suddenly cools, just as it does at sunset (…).
This means that hot air stops rising from the ground, causing the wind to drop in speed and change in direction.”

NASA states on its website that when a partial eclipse becomes total, the solar radiation at a particular location will decrease at a rate three times faster than the time of a normal sunset.

The next total solar eclipse will occur on April 8, 2024.
