TITLE: GCN CIRCULAR NUMBER: 10459 SUBJECT: GRB 100302A: Skynet/DAO Observations DATE: 10/03/02 22:45:23 GMT FROM: Josh Haislip at U.North Carolina J. Haislip, K. Ivarsen, A. LaCluyze, D. Reichart, R. Egger, A. Foster, J. Moore, A. Oza, M. Schubel, J. Styblova, A. Trotter, J. A. Crain, and M. Nysewander report: Skynet observed the Swift/BAT localization of GRB 100302A (Cummings et al., GCN 10458) with the 16" telescope at the Dolomiti Astronomical Observatory in Italy beginning 2.7 minutes after the trigger (1.3 minutes after notification) in Red, which we have calibrated to R. We do not detect the afterglow (Cummings et al., GCN 10458). Stacking only images that increase the limiting magnitude yields: mean 1-sig. 1-sig. time 3-sig. sys. stat. since lim. cal. cal. cal. trig. tel. exp. fil. mag. stars unc. unc.
