A total solar eclipse almost exclusive to scientists

It will only be visible in its phase of totality from Antarctica.

The total solar eclipse that will take place tomorrow will be an almost exclusive astronomical spectacle for a handful of scientists, since it will only be visible in its phase of totality from Antarctica, where very small teams of researchers work that occupy the permanent bases that they have some countries.

Very few people will have the chance to see the total solar eclipse tomorrow, but some institutions or research centers, including NASA, have scheduled live broadcasts of this phenomenon through their official channels thanks to the collaboration of some of the scientists integrated into the scientific expeditions now taking place in the Antarctic region.

Partially, and according to data from the National Astronomical Observatory, the eclipse will be visible in some very southern places of the southern hemisphere from 5:29 am (Universal Time or UTC), when the phenomenon can be observed in places far south of the Atlantic Ocean, and it will last until 9:37 a.m., although at that time you can only see southern Tasmania (Australia).

The “totality” phase of the eclipse will begin at 7:00 (UTC) at a point in the Atlantic Ocean located east of the Falkland Islands; It will cross the Weddel Sea and West Antarctica, ending at 8:06 at a point in the Antarctic Ocean opposite the Gezt Ice Barrier (in Antarctica).

The eclipse will occur when the Moon intervenes between the Earth and the Sun, which will cause a shadowing in those areas, which will be much more pronounced during the phase of totality in the Antarctic region.

Although it is “only” one more among the 200,000 million stars in the Milky Way, the Sun is the closest to Earth and the brightest star from Earth, so eclipses, and especially the “totals “Like the one that will be registered tomorrow, they are especially interesting for the scientific community since, according to the Astrophysical Institute of the Canary Islands (IAC), they allow a great variety of experiments and observations to be carried out.

Eclipses facilitate the study of the solar corona and make measurements of very high precision on the solar diameter, since the beginning and end of the “total” phase offer – underlines the IAC – precise references to carry out these measurements and advance in an essential question for scientists: whether the size of the Sun varies with time.

All scientific institutions insist on the importance, in order to make a safe observation, to take measures and use adequate means even when the sun is partially – or for the most part – obscured, and NASA has insisted, in the face of tomorrow’s astronomical event, in that it is not safe to look directly at the Sun and that normal sunglasses are not safe either.

NASA has stressed that it is only safe to look directly at the Sun without adequate protection during the short period of time in which the moon completely obscures the star, but has stressed that it is “crucial” to know when to remove that protection and return to use it. (I)
