TITLE: GCN CIRCULAR NUMBER: 13690 SUBJECT: GRB 120819A: Bassano Bresciano Observatory optical observations DATE: 12/08/20 13:05:16 GMT FROM: Ulisse Quadri at Bassano Bresciano Obs U.Quadri, L.Strabla, R.Girelli and A.Quadri report: We imaged the field of GRB 120819A detected by SWIFT(trigger 531428) with the robotic telescope of (IAU station 565) Bassano Bresciano Observatory, Italy. The observations started 6h 35min. after the GRB trigger(delay due to expecting the night) with our Schmidt telescope D=400mm F/D=3.1. Weather conditions were good. We co-added 2 series of 15 unfiltered CCD exposures of 120s each. We did not appear any reasonable optical counterpart in the error box of the XRTcandidate (Beardmore et al., GCNC 13681) at our limiting magnitude. Start End M.lim. 395min 454min 19.5 Magnitudes were estimated with the USNO-B1 cat. The message may be cited.
