45th European Symposium on Occultation Projects
will be held in Toulouse, France, 22 – 23. August 2026

The European Symposium on Occultation Projects (ESOP) is an annual scientific meeting organised by the International Occultation Timing Association/European Section (IOTA/ES).
It joins the community interested in stellar occultations phenomena, the field of observational astronomy which has recently seen a great development thanks to the Gaia astrometric mission.

In 2026 symposium takes place in hybrid mode in Toulouse, located in the southwest part of France. Toulouse is one of the European capitals of aeronautics and space and is home of Observatoire Midi-Pyrénées (OMP), which federates several laboratories of sciences of the universe, the planet and the environment around the missions of research, observation, teaching, dissemination of scientific culture and international cooperation.

As a traditional part of the ESOP, alongside the conference, additional trips will be offered, to tourist and scientific sites. In addition to a trip to downtown Toulouse, we suggest you visit the Pic du Midi observatory, the “Cité de l’Espace” (the Toulouse space museum), the city of Carcassonne, the Airbus factory and the Aeroscopia museum.

We will be glad to see you in Toulouse in person, but a free on-line participation via Zoom will also be offered after earlier registration.
