TITLE: GCN GRB OBSERVATION REPORT NUMBER: 1533 SUBJECT: XRF 020903: Optical observations DATE: 02/09/04 14:55:51 GMT FROM: Paul Price at RSAA, ANU P.A. Price, B.P. Schmidt (RSAA, ANU) and T.S. Axelrod (Arizona) report: We have observed the error-circle of XRF 020903 (Ricker et al. GCN #1530) with the robotic 50-inch telescope at Mount Stromlo Observatory beginning at Sep 4.42 UT. Observations consisted of 3x300 sec exposures in R_MACHO and cover the entire error circle to a limiting magnitude of approximately R ~ 19.8 mag. We do not identify any source in our images not present on the DSS2 upon visual inspection. Further observations are planned. This message may be cited.
