Member of: \nAAVSO - American Association of Variable Star Observers.\nISSP - Italian Supernovae Search Project.\nUAI/SSV - Unione Astrofili Italiani/sezione stelle variabili.\n\nThe observations started 8.31 hour after the GRB trigger,  \nwith our Schmidt telescope D=320/400 mm F/D=3.1.\n\nWeather conditions were good.\n\nWe co-added a series of exposures of 120 sec each.\n\nStart T0+      End T0+      Vlim\n8.31 hour    10.28 hour      19\n\nWe did not found any optical counterpart in the error box of the XRTcandidate.\n(S. B. Cenko (GSFC), V. D'Elia (ASDC), N.
