The observations\nwere started in semi-automatic mode since 2 minutes after the trigger.\n\nWe clearly detected the OT discovered by Swift/UVOT, MASTER-Net\n(Lipunov et al. GCNC #27324/27325/27327), FRAM-ORM (Jelinek et al.\nGCNC #27328), BOOTES-1 (Hu et al., GCNC #27329) with the coordinates:\nR. A. = 13:14:13.44, Decl. = +11:16:11.8 +/- 0\".5, Epoch = 2000.0.\n\nPreliminary R band photometry of the OT:\n\nTmid-T0, s   exp., s   Rmag +/- err\n\n151          30        15.29 +/- 0.06\n183          30        15.77 +/- 0.03\n230          30        15.97 +/- 0.12\n276          30        16.14 +/- 0.04\n388          60        16.49 +/- 0.05\n464          60        16.69 +/- 0.07\n541          60        16.99 +/- 0.04\n\nThe calibration were done against nearby SDSS stars (Lupton, 2005).",
