GCNC 3071)\nwith the TAROT robotic telescope (D=25cm) located at the Calern observatory,\nFrance. Observations started 90 seconds after the begining of the burst.\nThe source was at an elevation of 15 degrees above the horizon. The Moon did\nnot rise during the observation, though the burst source location was 19 deg\nfrom it. Nevertheless, haze was present, resulting in a loss of sensitivity.\nNo new source was detected after a comparison with the DSS2 R image.\nWe summarize below the limiting magnitude obtained by TAROT :\n\nBeg. burst event 2005-03-06 03:33:12 UT (from GCNC 3071) End. burst event\n2005-03-06 03:36:12 UT (from GCNC 3071)\n\nDate       from     to       Rmag    Remarks\n2005-03-06 03:35:19 03:35:49 >11     during prompt emission\n2005-03-06 03:36:42 03:40:32 >13\n2005-03-06 03:41:37 03:43:31 >14.4   6 min after the end of prompt emission\n2005-03-06 03:44:32 03:45:40 >13\n\nThis message is citable.",
