Transit of Mercury observation on May 9th [NOT TRANSLATED]
Transits of Mercury across the Sun occur about 14 times a century and occur when the orbit of the planet Mercury crosses the Earth’s orbit. This occurs in May and November. The main difference between the two seasons is that in May transits, Mercury is closer to the Earth and its diameter is somewhat greater than during November transits.

To observe the transit of Mercury is necessary to use a telescope because direct observation of the sun can be harmful to the human eye
The Institute of Cosmos Sciences (IEEC-UB) will broadcast the transit through the website ServiAstro where you will find more information about the event.
Observation at telescope
But if you want to observe the transit with a telescope, the Institute of Space Sciences (IEEC-CSIC) has several telescopes at its facilities on the Campus of the Autonomous University of Barcelona from which they will project the sun’s image on a screen and will provide homologated glasses to see the phenomenon live and safely. Moreover, the Institute of Cosmos Sciences (IEEC-UB) will install two telescopes in front of the Palau Reial in Barcelona to observe the transit
