The photometric observations were obtained at the Ege University Observatory, while the spectroscopic ones were carried out at Catania Astrophysical Observatory in the spectral range 5860-6700Å. We obtained a high quality radial velocity curve of the system that allowed us to give more accurate values of the orbital parameters.
