We report the discovery , from WASP and CORALIE , of a transiting exoplanet in a 1.54-d orbit .
The host star , WASP-36 , is a magnitude V = 12.7 , metal-poor G2 dwarf ( \mbox { $T _ { eff } $ } = 5959 \pm 134 K ) , with [ Fe/H ] = -0.26 \pm 0.10 .
We determine the planet to have mass and radius respectively 2.30 \pm 0.07 and 1.28 \pm 0.03 times that of Jupiter .

We have eight partial or complete transit light curves , from four different observatories , which allows us to investigate the potential effects on the fitted system parameters of using only a single light curve .
We find that the solutions obtained by analysing each of these light curves independently are consistent with our global fit to all the data , despite the apparent presence of correlated noise in at least two of the light curves .
