GCN Circular 10701
Dale A. Frail (NRAO) and Poonam Chandra (RMC) report on behalf of a larger collaboration: "We observed the localization of GRB 100424A (Hoversten et al. GCN 10667) the Expanded Very Large Array (EVLA) on April 27.14 UT at a center frequency of 8.46 GHz. We do not detect any radio source anywhere within the refined XRT error circle (Evans et al., GCN 10669) to a 3-sigma limit of 66 uJy. The EVLA is still undergoing active commissioning and we caution that these results should be considered preliminary.
