(LATT-OMP) report:\n\nWe imaged the field of GRB 080413 detected by SWIFT\n(trigger 309096) with the TAROT robotic telescope (D=25cm)\nlocated at the Calern observatory, France.\n\nThe observations started 21.8s after the GRB trigger\n(8.3s after the notice). The elevation of the field increased from\nfrom 11 degrees above horizon and weather conditions\nwere poor at the beginning of observations. The first\nimage showing stars started 480s after the trigger.\n\nWe detected the candidate couterpart mentioned by Rykoff\net al. (GCNC 7593) at the following position (+/- 2 arcsec):\n\nRA(J2000.0) = 19h 09m 11.85s\nDEC(J2000.0) -27d 40' 43.0\"\n\nUnfiltered magnitudes are:\nt0+480s to t0+570s : R > 12.5\nt0+1174s to t0+1263s : R = 15.0 +/- 0.2\nt0+1470s to t0+1650s : R = 15.3 +/- 0.2\nt0+2035s to t0+2215s : R = 15.5 +/- 0.2\n\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=  9.5236 lat=-15.8249\nand the galactic extinction in R band is 2.4 magnitudes\nestimated from D. Schlegel et al. 1998ApJ...500..525S.\n\nThis message may be cited.",
