These are the 7 stages of the phenomenon that will ‘turn’ day into night – El Financiero

‘To infinity and beyond!’. The next Monday April 8If you are a lover of astronomy or belong to those curious people who from time to time ‘take a look’ at the sky in search of the beauty of sunsets or UFOs, you cannot miss one of the most anticipated events of the year: the total solar eclipse.

The solar eclipse will be visible in Mexico, the United States and Canada and, together with its total and partial stage, it will have a duration of two hours and 41 minutesaccording to Institute of Geophysics from the National Autonomous University of Mexico (UNAM).

What is a total solar eclipse and why does it occur?

A total solar eclipse it happens when the Moon passes between the Sun and the Earthcompletely covering the face of the Sun. During this natural phenomenon, the sky will darken, as if it were dawn or dusk, explains the National Aeronautics and Space Administration (NASA).

What are the seven phases of the total solar eclipse?

The total solar eclipse that will be seen in Mexico has seven stages, ranging from a partial eclipse to totality and vice versa. According to NASA, these are the characteristics of each one:

partial eclipse

This occurs when the Moon passes between the Sun and the Earth and does not cover the Sun completely, so it can be seen in the shape of a crescent. In most of the placesthe partial eclipse phase will last between 70 and 80 minutes. The moment when the Moon ‘touches’ the Sun for the first time is also called first contact.

The shadow strips

In this phase you can see a series of long dark stripes, that move quickly and are separated by white spaces that can be seen on the sides of buildings or on the ground, before and after the Moon completely covers the Sunalthough they can be very faint and difficult to photograph.

This happens because Earth’s upper atmosphere has turbulent air masses that distort the light of defined edges of the solar surfacejust as they distort the light of the stars and make them flicker.

Baily’s pearls

As the Moon continues to pass in front of the Sun, several points of light shine around the edges of the Moon. Known as the Baily pearlsor Baily’s globules,These are rays of sunlight that radiate through the valleys along the horizon of the Moon. Due to its short duration, this phase may not be as noticeable to all observers.

The solar eclipse was seen with greater intensity in the United States

The diamond ring

When Baily’s pearls disappear, there will be a bright spot along the edge of the Moon’s shadow that resembles a giant diamond ring formed by the Sun’s atmosphere.

Also known as the second contactin this phase the Moon will have completely covered the Sun, so viewers may see a thin pink circle around the Moon and outer atmosphere of the Sunwhich looks like rays of white light.

During totality, it is possible to take off your glasses for a moment to appreciate the eclipse and give yourself a few seconds to observe the world around you. If the weather conditions Allow it, you may be able to see some particularly bright stars or planets in the darkened sky.

The shine reappears

The total eclipse is over! The Moon will continue its path passing across the face of the Sun, so you will begin to see a glow on the opposite side of where the diamond ring shined at the beginning. This is the lower atmosphere of the Sun, which begins to peek out from behind the Moon and this is when you will have to put your glasses back on or stop looking directly at the eclipse.

‘In reverse mommy’: Diamond ring, Baily pearls and fringes of shadow… again

The last stages of the eclipse mirror the beginning: you’ll see the diamond ring, Baily’s pearls, and shadow bands again before the entire Sun becomes visible again.

Where and at what time can you see the solar eclipse in Mexico?

The solar eclipse will have a total duration of 2 hours and 41 minutes. It will be seen in North and Central America; However, in some regions of the country, such as Mexico City, it will be seen partially, since the Moon is expected to cover 79 percent of the solar disk.

The Institute of Geophysics detailed that Mazatlán, Sinaloa, will have the best show. The total eclipse will last 4 minutes and 25 seconds; It will begin at 10:51 a.m. and the total phase of the eclipse will begin at 12:07 and end at 12:11, just when the Sun will be at the zenith, that is, at the highest point in the sky. After the total phase, the Sun will again be partially obscured, which will end at 13:32:07.

Other cities in Mexico where the total eclipse can be seen will be Durango, Torreon and Monclova, although with a shorter duration. However, most of the country will experience the partial eclipse.

Don’t forget special glasses: Recommendations for viewing the solar eclipse

Remember that what you can see during the eclipse will depend on weather conditions, as well as where you view it from, as clear skies are required to have the full experience, with a clear view of the Sun and Moon.

However, seeing the phenomenon directly can cause damage to the retinaand even, permanent blindness, Therefore, NASA recommends protecting your eyes while observing the event.

To do this, you can use certified sunscreens that comply with the ISO 12312-2 standard to avoid serious eye damage. These must be used at all times, except during total eclipse phasewhen It is safe to look directly at the Sun.

If you are going to see the eclipse with your family, remember to supervise children at all times and make sure they use solar filters appropriately.

Ready, have fun!
