Jansky Very Large Array (VLA) beginning on 2016 Mar 4.218 UT\n(18.32 hr post-burst) at a mean frequency of 9.8 GHz. In 1 hour of\nobservations, we do not detect any radio source within or around the\nenhanced XRT position (Evans et al., GCN 19132) or the optical afterglow\nposition (Butler et al., GCN 19131; de Ugarte Postigo et al., GCN 19136) to\na 3-sigma limit of 15.2 microJy. We therefore place a 3-sigma limit of 15.2\nmicroJy on the radio afterglow of GRB 160303A at 18.32 hr after the burst.\n\nWe thank the VLA staff for quickly executing these observations.\"",
