Thierry (AGORA),\nreport:\n\nWe imaged the field of GRB 221216A detected by SWIFT\n(trigger 1144698) with the Zadko robotic telescope (D=100cm)\nlocated at the observatory - Gingin, Australia.\n\nThe observations started 1.39h after the GRB trigger.\nThe elevation of the field decreased from\n35 degrees above horizon and weather conditions\nwere good.\n\nOn individual images taken between t0+4994.4s and t0+7433.4s,\nwe do not detect any OT with a limiting magnitude of: R > 17.5\n\nOn a co-added series of exposures between t0+4993s to t0+6613s,\nwe estimated a limiting magnitude of R > 19.0\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= 10.7381 lat=-49.4597\nand the galactic extinction in R band is 0.1 magnitudes\nestimated from D. Schlegel et al. 1998ApJ...500..525S.\n\nThis message may be cited.",
