Tennant (NASA-MSFC) report of radio\nobservations of GRB050401.\n\nWe observed the field of the GRB050401 using ATCA (6 km configuration)\nat Narrarbri, Australia on 2005 April 02 15.02 UT and April 03 14.22 UT.\nThe duration of each observation was 1 hour.\n\nWe do not detect signals above rms of 0.5 (4.8 GHz) and 0.6 mJy (8.64 GHz)\nin the field in each individual data set for the two observations. We also\ndo not find significant signal above an rms of 0.4 mJy for the combined\ndata set at 8.64 GHz. There appears to be a 2.5-sigma feature (rms of\n0.3 mJy) at the position of the source (ref GCN 3163) in the combined \ndata set at 4.8 GHz. The feature could be spurious given that the uv\ncoverage was poor and the observation duration was short.\n\nThe observations were granted as ToO (April 02) and discretion observation\n(April 03) by the ATNF director.",
