WASP-44 was observed between July and November 2009 by the WASP-South, a station of the SuperWASP planet-searching program based at the South African Astronomical Observatory.
The Leonhard Euler Telescope at La Silla Observatory in Chile was used to follow up on the discovery circling WASP-44, searching for a point at which the planet transited, or crossed in front of, its host star.
