GCN Circular 14318
W. Fong, B. A. Zauderer and E. Berger (Harvard) report: "We observed the position of the short-duration GRB 130313A (Gompertz et al., GCN 14293) with the Karl G. Jansky Very Large Array (VLA) beginning on 2013 March 14.44 UT (18.5 hr post-burst) at a mean frequency of 5.8 GHz. In 1 hour of observations, we do not detect any source within the BAT-refined position (Barthelmy et al., GCN 14296), within the latest XRT position (Osborne et al., GCN 14300), or in coincidence with any of the reported optical sources (de Ugarte Postigo et al., GCN 14302). We therefore place a 3-sigma limit of ~60 microJy on the radio counterpart of GRB 130313A at 18.5 hr after the burst."
