(IRAP-CNRS-OMP) report:\n\nWe imaged the field of GRB 140622 detected by SWIFT\n(trigger 602278) with the TAROT robotic telescope (D=25cm)\nlocated at the European Southern Observatory,\nLa Silla observatory, Chile.\n\nThe observations started 23.2s after the GRB trigger\n(12.7s after the notice). The elevation of the field decreased from\n61 degrees above horizon and weather conditions\nwere excellents. Images were not accessible during one week\ndue to a disk access problem.\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+23.2s to t0+83.2s : R > 17.5\n\nThe second image is 30.0s exposure in tracking mode:\nt0+96.6s to t0+126.6s : R > 18.0\n\nWe co-added a series of exposures:\nt0+96.6s to t0+389.1s : R > 18.4\n\nMagnitudes were estimated with the nearby USNO-B1 stars\nand are not corrected for galactic dust extinction.",
