TITLE: GCN GRB OBSERVATION REPORT NUMBER: 2674 SUBJECT: GRB040827 optical observations DATE: 04/08/27 19:07:08 GMT FROM: Arne A. Henden at USNO/USRA B. Monard (Bronberg Obs., bmonard@mweb.co.za) reports on behalf of the AAVSO International GRB network: Observations of the INTEGRAL error circle for GRB040827 (Mereghetti et al., GCN 2670, 2671, 2672) were made with the Bronberg 0.30m telescope + unfiltered CCD. Twenty-five 13-second exposures with UT midpoint of 040827.701 (5.0hrs after the burst) were stacked, with a limiting magnitude of 20.0CR (based on USNO-A red magnitudes). No new object is seen in a 15x15arcmin region centered on the INTEGRAL coordinates down to approximately CR=19.5 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.
