(LATT-OMP) report:\n\nWe imaged the field of GRB 060919 detected by SWIFT\n(trigger 230115) with the new TAROT robotic telescope (D=25cm)\nlocated at the La Silla observatory, Chile.\n\nFirst image was acquired 28.3s after the GRB trigger\n(5.2s after the notice). The field elevation decreased\nfrom only 2 degrees above horizon and weather conditions\nwere good. Images were taken during the prompt emission.\n\nDate of trigger : t0 = 2006-09-19T07:48:38.880\n\nFirst image is 60.0s exposure trailed. No OT is visible:\nt0+28.3s to t0+88.3s : R > 15.4\n\nSecond image is 30.0s exposure. No OT is visible:\nt0+94.2s to t0+124.2s : R > 15.8\n\nWe co-added a series of the 3\nfirsts not trailed exposures. No OT is visible:\nt0+94.2s to t0+196.4s : R > 15.9\n\nFourth non trailed image is a 90.0s exposure\nand covers the second gamma peak described by\nGuidorzi et al. GCNC 5575. No OT is visible:\nt0+292.3s to t0+382.3s : R > 15.8\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=343.8526 lat=-17.2471\nand the galactic extinction in R band is 0.5 magnitudes\nestimated from D. Schlegel et al. 1998ApJ...500..525S.\n\nThis message may be cited.",
