Frail (NRAO) reports on behalf of a larger collaboration:\n\n\"Using the Very Large Array at 8.5 GHz, we imaged a 2-arcminute radius\nnear the X-ray source S1, detected by the XMM (GCN#2464) within the\nINTEGRAL error circle (GCN#2459). A single radio source is detected\nclose to the center of S1 at (J2000), r.a. = 08:02:30.22, dec. =\n-39:51:02.8, with conservative errors of +/-0.4 arcsec. This source is\nnot detected in the NRAO VLA Sky Survey at 20-cm. The flux density of\nthis source is 0.5 mJy - typical for GRB afterglows. We caution that\nthe flux calibration at this stage is only preliminary.\n\nThe coincidences between the INTEGRAL position, and the position of\nthe XMM-S1 and VLA sources, argues for a real association. We will be\nundertaking further observations to test whether the radio source is\nthe afterglow of GRB 031203.\"",
