The IFCA, together with the AstroCantabria Group, organizes an observation of Mercury Transit on November 11 from 1:30 p.m. to 4:00 p.m. outside the IFCA headquarters, the Juan Jordá building. The reservation is not required.
This activity is part of the activities of the University of Cantabria Scientific Week.
We call "transit" of a planet to the apparent passage of it in front of the surface of the Sun. From Earth, we can observe the transit of those planets that are between the Sun and Earth and only when they are aligned with the Earth and with that star.
On November 11 the planet Mercury will be between the Earth and the Sun and we will be able to see how it passes in front of the solar disk. On the outside of the IFCA building a projection of the Sun will be made on a screen (you should never look at the Sun directly nor with optical instruments without adequate protection) and we will observe the "transit" as a small shadow that moves slowly in front of the solar disk. Solar telescopes will also be available so that the visitor can observe this transit with them.
There are 13 transits of Mercury per century and the next one will not occur until November 13, 2032.
