TITLE: GCN GRB OBSERVATION REPORT NUMBER: 2062 SUBJECT: GRB030329 Further RBO Optical Observations DATE: 03/04/01 19:19:49 GMT FROM: Justin Schaefer at U of Wyoming <schaefju@uwyo.edu> S. Savage, J. Schaefer, D. Gibbs (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 Torii (GCN 1986), in the Johnson V filter with the RBO 0.6m telescope at Red Buttes Wyoming. We obtained 25, 300s exposures. Observations were undertaken between 02:26UT and 6:00UT, on March 31st. The observations were carried out under fair seeing 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=16.71, which faded by 0.15 mag during our observational period; however, there appeared to be a brightening. Errors were on average +/- 0.018. Further aperture photometry is being performed and observations are planned. This message may be cited.
