GCNC\n29448, D'Elia et al. GCNC 29452, and Lien et al GCNC 29467), obtaining a\nset of 30 x 60 s R-band images starting at 03:37:09.2 UT, i.e. ~97min post\ntrigger.\n\nWe clearly detect the source reported by other telescopes (Lipunov et al.\nGCN 29447, Fernandez-Garcia et al. GCNC 28763, de Ugarte Postigo et al GCNC\n29450, Breeveld & Laha GCNC 29457, and Strausbaugh & Cucchiara GCNC 29459).\nAt the sum of all available images (Tmid=T0+113.2min) we measure the\noptical afterglow with the brightness R=17.6+-0.2 (Vega) as calibrated\nagainst the Atlas catalogue and Lupton transformations.",
