Description
We present the first high-resolution observations of the optical afterglow of a gamma-ray burst. The spectra show that the matter of the host galaxy in the circumburst region is complex, with many components contributing to each system. Also the presence of low- and high-ionisation lines allows rather strong constraints on the gas ionisation parameters of the various components to be derived. These can be interpreted as density fluctuations on top of a regular R-2 wind density profile
