 | | The existence of small, active research groups at the University of La Laguna (Tenerife) and Granada (Spain) proved to be a decisive factor prompting the CSIC to create the Instituto de Astrofísica de Canarias (IAC) and the Instituto de Astrofísica de Andalucía (IAA), with headquarters in La Laguna (1974) and in Granada (1975), respectively. |
 | | At the time, this observatory, founded in 1902, had a mountain station situated on the Sierra Nevada mountain, at Mohón del Trigo peak (2,605 m in altitude), equipped with a small Cassegrain telescope with a 32-cm aperture, used jointly with the Royal Greenwich Observatory (RGO) of the UK for stellar-photometry studies. |
 | | In this way, the CSIC made a commitment to construct the Sierra Nevada Observatory (OSN) on the slope Veleta Peak, and the foreign institutions in compensation donated two telescopes, of 60 and 75 cm, respectively, to be installed in this observatory and to be used jointly. |
