DESCRIPTION:Planetary transits play an important role in the study of extr
 asolar planets as multi-wavelength observations of planetary transits prov
 ide measurements of the planetary transmission spectrum. This in turn enco
 des information on the planet's atmospheric composition\, and the presence
  of high-altitude cloud structures.\nI will present our ongoing observing 
 program targeting several hot giant planets with ground-based facilities\,
  focusing on results obtained with the VLT/FORS2 instrument. We made use o
 f FORS2's multi-object spectroscopy mode\, and I will briefly discuss stra
 tegies to deal with the instrumental limitations affecting FORS2. Finally\
 , I will show results for two targets: the 1400 K Saturn WASP-49b\, and th
 e more mildly irradiated WASP-80b\, a hot Jupiter orbiting a K7V star.
