GCN Circular 2703
B. Monard (Bronberg Obs.) reports on behalf of the AAVSO International GRB network: Observations of the HETE error circle for GRB040912 (Butler et al., GCN 2701; HETE trigger 3557) were made with the Bronberg 0.30m telescope + unfiltered CCD. Fifty-five 28-second exposures with UT midpoint of 040912.813 (5.3hrs after the burst) were stacked, with a limiting magnitude of 20.2CR (based on USNO-A red magnitudes). The field was centered at the revised ground analysis coordinates, with a field of view of 20arcmin(E/W) x 13arcmin(N/S), covering all but the extreme north and south limits of the error circle. No new object is seen 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.
