(IRAP-CNRS-OMP) report:\n\nWe imaged the field of GRB 120913B detected by SWIFT\n(trigger 533613) with the TAROT robotic telescope (D=25cm)\nlocated at the European Southern Observatory,\nLa Silla observatory, Chile.\n\nThe observations started 30.6s after the GRB trigger\n(17.7s after the notice). The elevation of the field decreased\nfrom 26 degrees above horizon and weather conditions\nwere good.\n\nWe detect a new fading source in the error box given\nby SWIFT. We detected the candidate couterpart\nmentioned by LaCluyze et al. (GCNC 13764)\nat the following position (+/- 2 arcsec):\n\nRA(J2000.0) = 14h 14m 38.57s\nDEC(J2000.0) -14d 30' 55.8\"\n\nOT raised until R=15.8 5 min after the GRB.\nNow the afterglow is fading.\n\nMagnitudes were estimated with the nearby NOMAD1 star\n0754-0289300 (R.A.=213.6332611 Decl=-14.5238889 J2000)\nR=15.99. MAgnitutes are not corrected for galactic dust\nextinction.\n\nN.B. Galactic coordinates are lon=331.3041 lat=+43.7095\nand the galactic extinction in R band is about 0.2 magnitude\nestimated from D.
