Photometric data were acquired for 4 transits, and high precision radial velocity measurements were simultaneously acquired with SARG at TNG for one transit. The template spectra of HD 17156 was used to derive effective temperature, gravity, and metallicity. A fit of the photometric and spectroscopic data was performed to measure the stellar and planetary radii, and the spin-orbit alignment. Planet orbital elements and ephemeris were derived from the fit. Near infrared adaptive optic images was acquired with ADOPT at TNG. We have found that the star has a radius of RS=1.44±0.03R and the planet RP=1.02±0.08R{jup} The transit ephemeris is Tc=2454756.73134±0.00020+N*21.21663±0.00045 BJD. The analysis of the Rossiter-Mclaughlin effect shows that the system is spin orbit aligned with an angle Beta=4.8±5.3deg The analysis of high resolution images has not revealed any stellar companion with projected separation between 150 and 1000 AU from HD17156. Here we present the photometric data of the transits of HD 17156b. Description: This table contains the photometric time serie obtained for a series of transits of the planet HD 17156b. The first column gives the date as Barycentric Julian Days (BJD), the second one gives the flux normalized to the out-of-transit average value, and the third one gives the Identification code of each observation.
