TITLE: GCN GRB OBSERVATION REPORT NUMBER: 2312 SUBJECT: GRB030723, optical observations DATE: 03/07/23 21:38:26 GMT FROM: Arne A. Henden at USNO/USRA <aah@nofs.navy.mil> B. Monard (Bronberg Obs.) reports on behalf of the AAVSO International GRB network: Observations of the HETE XRF/GRB030723 (triger 2777) error circle were made with the Bronberg 0.30m telescope + unfiltered CCD. Ten 45-second exposures with UT midpoint of 030723.806 (12.9hrs after the burst) were stacked, with a limiting magnitude of 20.5CR (based on USNO-A red magnitudes). No new object is seen down to approximately CR=20.0 when comparing against a DSS2-red image. The AAVSO International GRB network is greatful for a generous grant from the Curry Foundation and to NASA for the financial support for the High Energy Workshops for Amateur Astronomers.
