The history of astronomy at Atacama has always been related to its clear, dark skies and the natural conditions of the driest desert of the world. One of the first register than can be found are from 1893 when the american astronomer J.M. Shaeberle was one of the first to explore Atacama skies to observe a total eclipse in proximity of the town of Vallenar. A few years later, in 1889, the geologist L. Fletcher of the British museum of London finished a collection of meteorites collected in Atacama. However, is was not until the exploratory trip made for the astronomer H.D. Curtis in 1909 that the Atacama region was considered for professional astronomers as a posible site for telescope.
