TITLE: GCN GRB OBSERVATION REPORT NUMBER: 1316 SUBJECT: GRB 020331: Optical observations DATE: 02/03/31 22:51:51 GMT FROM: Paul Price at RSAA, ANU at CIT P.A. Price and M.C. Begam (RSAA, ANU) report: We have imaged the error-circle of GRB 020331 with the SSO 40-inch telescope + direct imager at 2002 Mar 31.79 UT (approximately 2.5 hours after the burst). Our images consisted of individual 600 sec exposures and covered approximately 60% of the refined HETE error circle (Ricker et al., GCN #1315) down to approximately R ~ 19.3 mag. We do not find any afterglow candidate from visual comparison of our images with the Digitised Sky Survey. Further observations are planned. This message may be cited.
