(LATT-OMP) report:\n\nWe imaged the field of GRB 060814 detected by SWIFT\n(trigger 224552) with the TAROT robotic telescope (D=25cm)\nlocated at the Calern observatory, France.\n\nFirst image was acquired 21.5s after the GRB trigger\n(6s after the notice). 3 first images were recorded\nduring the gamma propt emission.\n\nThe field elevation decreased from 11 degrees\nabove horizon and weather conditions were good.\n\nDate of trigger : t0 = 2006-08-14T23:02:18.816\n\nFirst image is 60s exposure trailed. No OT is visible:\nt0+21.5s to t0+81.5s : R > 14.8\n\nSecond image is 30s exposure. No OT is visible:\nt0+88s to t0+118s : R > 15.7\n\nThird image is 30s exposure. No OT is visible:\nt0+125s to t0+155s : R > 15.7\n\nFourth image is 30s exposure. No OT is visible:\nt0+161s to t0+191s : R > 15.7\n\nWe co-added a series of exposures. No OT is visible:\nt0+88s to t0+228s : R > 17.4\n\nMagnitudes were estimated with the nearby USNO-B1 stars\n\nGalactic coordinates are lon= 24.9891 lat=+63.2011\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.",
