(LAT-OMP) report:\n\nWe imaged the entire field (1 x1 deg) of GRB 050910a detected by HETE\n(Trigger #3924) with the TAROT robotic telescope (D=25cm) located at the\nCalern observatory, France. Observations started 8 seconds after the\nGCN notice (and 25 s after the GRB). The field had an elevation of\n46 degrees above horizon at the begining of the observations.\nAll images were taken withour any filter.\n\nFirst six images taken between 2005-09-10T01:16:44.86 (GRB +  25s)\nand 2005-09-10T01:19:31.50 (GRB + 192s) were co-added. The afterglow\nis not detected. The limiting magnitude is estimated to be\nR=18.9 +/- 0.1 comparing with the USNO-B1 nearby stars.\n\nA second set of images taken between 2005-09-10T01:20:00.51\n(GRB + 221s) and 2005-09-10T02:05:10.63 (GRB + 2931s) we co added.\nThe limiting magnitude is estimated to be\nR=19.3 +/- 0.1 comparing with the USNO-B1 nearby stars.\n\nThis notice can be cited.",
