GCN Circular 12227
A. Zauderer, E. Berger (Harvard), and D.A. Frail (NRAO) report on behalf of a larger collaboration: "We observed the Swift burst GRB 110731A (GCN 12215) with the EVLA beginning on 2011 Aug 1.15 UT (0.68 days after the burst). Observations were performed at 5.75 and 22 GHz for about 30 min at each frequency. No radio source is detected in coincidence with the optical afterglow (GCN 12215), to a 3-sigma limit of ~50 microJy at 5.75 GHz. Additional observations are planned."
