Frail (NRAO) report on behalf of a\nlarger collaboration:\n\n\"Following our preliminary radio observations (GCN#3933), we have\nundertaken four further observations of the field of GRB050906 with\nthe VLA at frequency of 8.46 GHz. In time order, they were centered on\nthe possible X-ray counterpart position (GCN#3956), the previously\nreported radio source (GCN#3933), and two epochs of the refined BAT\nerror circle (GCN#3935). The observations were taken on September\n10.35, 11.50, 11.52 and October 3.41 (all dates UT).\n\nWe find no radio sources within the XRT error circle with a limiting 2\nsigma flux density of 61 uJy. The previously identified radio source,\n(GCN#3933), which now lies outside of the refined BAT error circle,\nhas shown no significant variability and is likely a background\nextragalactic source.\n\nWithin the refined BAT error circle (GCN#3935) there are no\nsignificantly variable radio sources. The typical rms noise of each\nobservation is 40-50 uJy.\n\nThe National Radio Astronomy Observatory is a facility of the National\nScience Foundation operated under cooperative agreement by Associated\nUniversities, Inc.\"",
