TITLE: GCN CIRCULAR NUMBER: 13109 SUBJECT: Skynet/Dolomiti Observations of GRB120326A DATE: 12/03/26 03:02:32 GMT FROM: Aaron LaCluyze at U.North Carolina A. LaCluyze, J. Haislip, K. Ivarsen, M. Maturi, D. Reichart, J. Moore, H. T. Cromartie, R. Egger, A. Foster, N. Frank, M. Nysewander, A. Oza, E. Speckhard, A.Trotter, and J. A. Crain report: Skynet observed the Swift/XRT localization of GRB 120326A (Swift trigger #518626) with the Dolomites Astronomical Observatory located at the Carlo Magno Hotel Spa Resort in Italy. Observations in SDSS g',r',i' and z' began 93 seconds after the trigger (113 seconds after the burst). We detect an optical transit at the position reported by Klotz et. al. (GCN 13107). Stacking images and calibrating to USNO B1.0 stars yields the following: Mean Time Since triger Tel Exposures Filter Magnitude 37.23 m DAO 3 x 160 s g¢ 20.770 39.90 m DAO 4 x 160 s r¢ 19.868 51.48 m DAO 5 x 160 s i¢ 19.236
