(IRAP-CNRS-OMP) report:\n\nWe imaged the field of GRB 131026A detected by SWIFT\n(trigger 575905) with the TAROT robotic telescope (D=25cm)\nlocated at the European Southern Observatory,\nLa Silla observatory, Chile.\n\nThe observations started 86.9s after the GRB trigger\n(13.7s after the notice). The elevation of the field decreased from\n12 degrees above horizon and weather conditions\nwere good.\n\nThe first image is trailed with a duration of 60.0s\n(see the description in Klotz et al., 2006, A&A 451, L39).\nWe do not detect any OT with a limiting magnitude of:\nt0+86.9s to t0+146.9s : Rlim = 16.8\n\nThe second image is 30.0s exposure in tracking mode:\nt0+160.5s to t0+190.5s : Rlim = 17.4\n\nWe co-added a series of exposures:\nt0+160.5s to t0+451.9s : Rlim = 18.9\n\nMagnitudes were estimated with the nearby NOMAD1 stars\nand are not corrected for galactic dust extinction.\n\nN.B. Galactic coordinates are lon=125.5580 lat=-30.3300\nand the galactic extinction in R band is about 0.2 magnitude\nestimated from D. Schlegel et al. 1998ApJ...500..525S.",
