TITLE: GCN CIRCULAR NUMBER: 14647 SUBJECT: GRB 130513A: Bassano Bresciano optical upper limit DATE: 13/05/14 21:49:31 GMT FROM: Ulisse Quadri at Bassano Bresciano Obs U.Quadri, L.Strabla, R.Girelli and A.Quadri report: We imaged the field of GRB 130513A (INTEGRAL trigger 6842; Mereghetti et al., GCN 14630) with the robotic telescope of (IAU station 565) Bassano Bresciano Observatory, Italy. The observations started (after the dusk) 12h 19m after the GRB trigger, with our Schmidt telescope D=400 mm F/D=3 Weather conditions were very good. We co-added 2 series of 10 unfiltered CCD exposures of 120s each. We did not found any optical counterpart in the Swift-XRT error circle (Evans & Marshall, GCN Circular 14635) at our following limiting magnitude: . Start End Mlim T0+ T0+ 12.3h 13.0h 19.0 Magnitudes were estimated with the USNO-B1 cat. and are not corrected for galactic dust extinction. The message may be cited.
