Abstract: We report photometry and spectroscopy of the bright SN 2003lw, associated with GRB031203 at a redshift z = 0.1055. The spectra show a pronounced similarity with those of SN 1998bw and SN 2003dh, associated with GRB980425 and GRB030329 respectively. Therefore, the three best-confirmed GRB/SN associations involve a hypernova. The gamma-ray and afterglow properties of GRB031203 are quite different from those of most GRBs, but are broadly similar to those of the nearby GRB980425. It is therefore remarkable that the associated SNe are quite homogeneous in all these events.
