TITLE: GCN GRB OBSERVATION REPORT NUMBER: 1289 SUBJECT: GRB 020321: Optical observations DATE: 02/03/22 00:54:03 GMT FROM: Paul Price at RSAA, ANU at CIT P.A. Price (RSAA, ANU), B. Jones (Nottingham), B.A. Peterson (RSAA, ANU) report on behalf of a larger collaboration: We observed the refined error circle of GRB 020321 (GCN #1285) with the SSO 40-inch telescope + WFI at 2002 Mar 21.62 UT in poor seeing conditions. Our 2x600 sec observations in R band cover the entire error circle to a limiting magnitude of R ~ 20.5 mag. We do not detect any objects at the positions quoted by Henden & Nelson (GCN #1186). However, we detect one object at coordinates RA: 16:11:56.74 DEC: -83:39:57.3 J2000 (with approximate error of 0.5 arcsec) with R ~ 20 mag that does not appear to be on the DSS-2 red plate. Further observations are required to determine whether this source is the afterglow of GRB 020321. This message may be cited.
