(LATT-OMP) report:\n\nWe imaged the field of GRB 081003 detected by INTEGRAL\n(trigger 5361) with the TAROT robotic telescope (D=25cm)\nlocated at the Calern observatory, France.\n\n2008-10-03T20:48:45.809\n\nThe observations started 29.7s after the GRB trigger\n(7s after the notice) when the gamma emission was\nstill active. The elevation of the field decreased\nfrom 41 degrees above horizon and weather conditions\nwere good.\n\nThe date of trigger : t0 = 2008-10-03T20:48:16.09\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 at the position provived\nby Gotz (GCNC 8317) with a limiting magnitude of:\n\nt0+29.7s to t0+89.7s : R > 16.9\n\nThe second image is 30.0s exposure in tracking mode:\nt0+97.0s to t0+127.0s : R > 17.4\n\nMagnitudes were estimated with the nearby USNO-B1 stars\nand are not corrected for galactic dust extinction.\n\nN.B. Galactic coordinates are lon= 48.80 lat= +5.63\nand the galactic extinction in R band is 2.0 magnitudes\nestimated from D. Schlegel et al. 1998ApJ...500..525S.\n\nThis message may be cited.",
