Aims. The aim of this paper is to study the Gamma Ray Burst (GRB) environment through the analysis of the optical absorption features due to the gas surrounding the GRB. Methods. To this purpose we analyze high resolution spectroscopic observations ($R=20\,000$–45 000, corresponding to 14 km s -1 at 4200 A and 6.6 km s -1 at 9000 A) of the optical afterglow of GRB050730, obtained with UVES@VLT ~4 h after the GRB trigger. Results. The spectrum shows that the ISM of the GRB host galaxy at $z = 3…
