Ezequiel Calbet i la mesura de l'eclipsi de 1842 Authors Francesc X. Barca Salom Abstract On 8 July 1842 an eclipse of Sun was observed in Catalonia. Since this eclipse, European scientists have postulated that the protuberances that surrounded themoon formed part of the Sun. The astronomer Francis Baily travelled to Pavia and the mathematician Llorenç Presas was sent by the University of Barcelona to join François Arago in Perpignan to observe this eclipse. Despite the fact that the Sun was not completely covered in Barcelona, Ezequiel Calbet, professor of the Nautical School, made an observation from the roof of the building housing the Catalan Board of Commerce. This paper presents the results of this eclipse and also those of the eclipses of the moon in 1844 and in 1848. These activities provide evidence that nautical astronomy contributed decisively to the development of astronomy in Catalonia.
