Where and how to see the transit of Mercury ahead of the Sun this Monday (it will not be repeated until 2032)

New unmissable astrological phenomenon. Mercury will travel ahead of the Eastern Sun Monday November 11, something that will be visible between 1:30 p.m. and 7:00 p.m. in Spain. This fact is not usual, in fact we will not see another traffic until November 13, 2032.

The end of the transit will not be visible on the Peninsula for a few minutes but it will be seen from the Canary Islands, just when the sun sets on the horizon and as long as the sky is completely clear, as explained by the National Astronomical Observatory (OAN).

What is the transit?

The transit is an astronomical phenomenon that consists in that a certain planet passes in front of the surface of the Sun. From our Earth you can only contemplate the transit of Venus and Mercury because they are the planets that are located between the Earth and the solar star.

The planets do not revolve around the Sun in the same plane but their orbits have a certain inclination with with respect to that of the Earth, which is taken as a reference. The orbit of Mercury has an inclination of 7º with that of the Earth, and that of Venus 3.4º.

The tilt value makes most of the time how these planets pass or go up or below the solar disk, not producing any traffic. On average, there are 13 transits of Mercury per century and the next one visible from Spain will happen on November 13, 2032.

For the transit of Mercury to be completely visible, it is necessary that the Sun, Mercury and Earth stay aligned at the time of the lower conjunction of the planet, that is, when Mercury passes between Earth and the Sun. That only happens when Mercury is at a certain point in its orbit.

What can be seen and how

This phenomenon will be visible this Monday. What we can see is how a black dot moves ahead of the Sun for 4 hours and 23 minutes from 13:37 to 18:01 in Madrid, at which time the sun will set. The central moment of the phenomenon will occur at 16:20.

When the sun goes down in Madrid, it can no longer be observed. Of course, depending on where one is the traffic completion It will be different. If the center of the Earth is taken as a reference, this will happen at 19:04.

Precautions

The National Astronomical Observatory asks to take certain precautions if you want to see this phenomenon. To do it in a right way and avoid eye damage, the OAN recommends using a sunscreen that is placed before the objective of a telescope or binocular. Observation with solar eclipse glasses is also safe, but it is very difficult to see the small disk of Mercury.
