Observatorio el sauce: hosting robotic science in chile

The "El Sauce" Observatory is a robotic remote observatory in Chile designed for hosting medium and small sized telescopes (<≈ 1m diameter). It currently hosts telescopes used for astro-photography, private and scientific purposes. Telescopes at El Sauce have been contributing regularly to follow-up of TESS objects of interests, and have participated in follow-up of gravitational wave events. In this work we describe the observatory, its infrastructure, and future scientific facilities that are planning to install at "El Sauce" such as a node of the ATLAS project.
