ExoClock is a very successful international program initiated and managed by Anastasia Kokori (UCL-CSED) and Angelos Tsiaras (Aristotle University of Thessaloniki) to monitor transiting exoplanets in order to keep their ephemerides up-to-date (ExoClock catalogue).

We strongly believe that everyone can contribute to real research and become part of a bigger project, such as a space mission. The ExoClock team have created special tools and educational guides for any observatory that would like to support Ariel and exoplanet science. Everyone with some basic equipment, including a telescope and a CCD camera, can participate in the effort of monitoring the planets’ host stars.
