(IRAP-CNRS-OMP) report:\n\nWe imaged the field of GRB 131105A detected by SWIFT\n(trigger 576738) with the TAROT robotic telescope (D=25cm)\nlocated at the European Southern Observatory,\nLa Silla observatory, Chile.\n\nThe observations started 231s after the GRB trigger\n(14s after the notice). The elevation of the field increased from\n37 degrees above horizon and weather conditions\nwere good.\n\nA first series of 30.0s exposure images was acquired in tracking mode.\nWe do not detect the afterglow candidate of Xu et al. (GCNC 15447)\nwith limiting magnitudes of:\nt0+231s to t0+261s : Rlim = 18.3\nt0+311s to t0+341s : Rlim = 18.3\nt0+351s to t0+381s : Rlim = 18.3\nt0+391s to t0+421s : Rlim = 18.3\nt0+432s to t0+462s : Rlim = 18.3\n\nNext series were co added by drizzling to increase the detectivity.\nt0+ 472s to t0+1131s : Rlim = 19.0\nt0+1141s to t0+1658s : Rlim = 19.0\n\nMagnitudes were estimated with the nearby NOMAD1 stars\nand are not corrected for galactic dust extinction.\n\nThis message may be cited.",
