Berger (Caltech) report on behalf of the Caltech-NRAO-CARA GRB collaboration: "On 2002, October 05.29 UT we observed the position of the optical afterglow candidate reported by D. Fox (GCN 1564) with the VLA at 22.5 GHz (1.3 cm). With a quick-look reduction we detect a 0.6 mJy radio source coincident with the position of the optical source. Further observations with the VLA are planned." This message may be cited.
