A group of amateur astronomers from the Asturian Astronomical Society Omega has carried out a scientific observing stay using the 1.23 m telescope at the Calar Alto Observatory, within the framework of the III Javier Gorosabel PROAM Collaboration Award, granted by the Spanish Astronomical Society.
October 9th 2025
The Calar Alto Observatory, the Institute of Astrophysics of Andalusia (IAA-CSIC), and the University of Almería are organizing an international conference about robotic telescopes in Retamar-El Toyo (Almería). Many astronomical observations are already being performed with this kind of autonomous instruments, which will become even more common in the future.
An international meeting about robotic telescopes, gathering more than 100 participants from 26 countries giving 55 talks, is being held this week (October 6-10, 2025) at the Barceló Cabo de Gata Hotel in Retamar-El Toyo (close to Almería city). This is the eighth meeting of its kind since 2009, entirely dedicated to autonomous telescopes. Such devices allow observations to be made in various areas of astrophysics, with hardly any human intervention.

Last Monday, June 30th, was "Asteroid Day." Calar Alto is part of ESA's Planetary Defense project, so we joined in the celebration. Using our smallest telescopes, the 1.23 m telescope and the Schmidt camera, we are discovering new objects while refining the orbits of known asteroids.
