(LATT-OMP) report:\n\nWe imaged the field of GRB 070330 detected by SWIFT\n(trigger 273180) with the TAROT robotic telescope (D=25cm)\nlocated at the European Southern Observatory,\nLa Silla observatory, Chile.\n\nThe observations started 2.5 hours after the GRB trigger\n(the field was not risen when the burst occured).\n\nThe date of trigger : t0 = 2007-03-30T22:51:30.816\n\nWe co-added a series of 180s exposures:\nWe do not detect any OT at the XRT position\n(Grupe et al. GCNC 6234) with a limiting magnitude of:\n\nt0+2.5h to t0+3.5h : R > 17.4\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=329.9005 lat=-18.5620\nand the galactic extinction in R band is 2.0 magnitudes\nestimated from D. Schlegel et al. 1998ApJ...500..525S.\n\nThis message may be cited.",
