We present results from Spitzer Space Telescope observations of three close-in giant planets: 51 Peg b, HD 179949 b and HD 209458 b. Such short-period planets are expected to be tidally locked and therefore to have permanent dayand night-sides. They may be nearly isothermal, or exhibit a large day/night temperature contrast, depending on how efficiently their gaseous envelope redistributes incident energy to their night-side. Indeed, the various atmospheric models of hot Jupiters are not in agreement about the value of this redistribution factor. In an attempt to resolve this controversy, IRAC 8.0 micron images were taken at 8 points throughout each planet's orbit. The phase variability of the systems was used to constrain the diurnal flux difference of the planets. By making suitable assumptions about their albedo, we were able to constrain these planets' day/night temperature contrast.
