Between March 5, 2008 and March 9, 2009, WASP-24 was under the observation of both the Northern and Southern branches of the SuperWASP project, a ground-based consortium aiming to discover planets that transit (cross in front of) their host stars with respect to Earth.
Information collected by the Faulkes telescopes was extrapolated to reveal the characteristics of the star, and from there of the planet.
