Benetti, (TNG), on behalf \nof a larger collaboration, report:\n\n\n\"We acquired optical R-band images of the central part of the GRB000812\nerror box (Hurley et al., GCN #770) on 2000 August 16.961 UT with\nTNG+Dolores for a total exposure time of 30 minutes. Seeing was 1.1 arcsec.\nThe pointing was centered on the uncatalogued radio source found by Frail\net al. (GCN #771).\nThe observations were heavily hampered by the full moon and by a 8th\nmagnitude star located ~40 arcsec from the radio position; nevertheless,\nthey were considerably deeper than the DSS-II.\n\nPhotometric calibration was performed using USNO-A2.0 catalog stars.\nNo new object brighter than the DSS-II limit is apparent all over the\nimage. Also, no object down to a 3-sigma limiting magnitude R ~ 23 \nis present inside the radio source error box.\".\n\n\nThis message can be cited.",
