TITLE: GCN GRB OBSERVATION REPORT NUMBER: 2042 SUBJECT: GRB 030329 RBO V Optical Observations DATE: 03/03/31 07:51:21 GMT FROM: Justin Schaefer at U of Wyoming J. Schaefer, S. Savage (University of Wyoming) Report on behalf of the University of Wyoming GRB response team and the FUN GRB collaboration: We observed the optical afterglow of GRB 030329, identified in (GCN 1986), in the Johnson V-Band with the RBO 0.6m telescope at Red Buttes Wyoming. We obtained 6, 180s exposures on March 30th UT. The observations were carried out under fair to poor conditions. Aperture photometry was performed and calibrated utilizing the standards reported by Henden et al., (GCN 2023). We initially measured the magnitude of the OT to be V=15.57 +/- 0.01 at 02:59UT which faded by 0.06 during the short observational period. Further observations are currently being undertaken, and more data for the V filter will follow. This message may be cited
