GCNC13763, Swift trigger\n#533613). Observations started 24.4s after the GRB\ntrigger.\n\n10s R-band (lambda_eff = 640nm) images with a limit of\n~16.0 were obtained. We identify the optical transient\nreported by LaCluyze et al. (GCNC13764) and Klotz et\nal. (GCNC13765) with a magnitude R = 16.3 +/- 0.2 on a\nsum of 8x10s images obtained between 271 and 364s after\nthe GRB.\n\nThis message may be cited",
