Astronomers from the Agrupación Astrónomica de Sabadell together with the Telescopic Operations Technicians of the Instituto de Astrofísica de Canarias, Marta Puig Subirà and Miguel Rodríguez Alarcón, have detected the transit of the exoplanet WASP-156b, catalogued as a high priority objective by the Exoclock project. The depth of the detected transit was only 6 millimagnitudes and will contribute to improve the ephemerides available for the ARIEL (Atmospheric Remote-sensing Infrared Exoplanet Large-survey) mission of the European Space Agency.
