TITLE: GCN GRB OBSERVATION REPORT NUMBER: 1410 SUBJECT: GRB 020603: Optical observations DATE: 02/06/05 18:11:25 GMT FROM: Paul Price at RSAA, ANU P.A. Price, B.P. Schmidt (RSAA, ANU) and T.S. Axelrod (Steward Obs, Arizona) report: We have observed the error-box of GRB 020603 (Hurley et al., GCN #1409) with the robotic 50-inch telescope at Mount Stromlo Observatory, commencing at 2002 June 5.69 UT. Exposures consisted of 3x300 sec integrations in MACHO_R, and cover the entire error box to a limiting magnitude of R ~ 19 mag. We do not find any optical afterglow candidate within the error box on visual comparison with the second Digitised Sky Survey. This message may be cited.
