The Wide Angle Search for Planets (WASP) is a highly successful program that has been responsible for the discovery of more than 140 exoplanets to date. A number of these planets orbit bright stars and are therefore ideal candidates for in-depth investigation and in particular atmospheric characterisation. We can model the dayside atmosphere of a planet by measuring the change in flux during an occultation of a planet by its host star at multiple wavelengths. Here we present results from ground-based observations of the hot Jupiter WASP-48b; a planet in a circular orbit that shows a lack of thermal inversion.
