ExoClock is a project initiated and managed by Anastasia Kokori and Angelos Tsiaras at UCL to monitor transiting exoplanets in order to keep their ephemerides up-to-date.

ExoClock is supported by the ARIEL Ephemerides Working Group.

Everyone with some basic equipment, including a telescope and a CCD camera, can participate in the effort of monitoring the planets’ host stars.
