Photographer, Alfons Puertas has captured the silhouette of the Serra de Tramuntana, Majorca from 300 kilometres away in Barcelona.
Majorca can only be seen from the Catalan coast a few times a year when conditions are perfect, with no clouds, a clear atmosphere and not too much light.
This very rare phenomenon was captured early in the morning from the Fabra Observatory in Barcelona which was built by Josep Domenech i Estapà in 1904.
