GCN Circular 10768
Poonam Chandra (RMC) and Dale A=2E Frail (NRAO) report on behalf of a larger collaboration: We observed GRB 100513A (Baumgartner et al. GCN 10746) with the Expanded Very Large Array (EVLA) on May 14.02 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 10751) to a 3-sigma limit of 60 uJy. The peak flux at the PAIRITEL afterglow position (Morgan et al., GCN 10747) is -43+/-20 uJy. The EVLA is still undergoing active commissioning and we caution that these results should be considered preliminary=2E The National Radio Astronomy Observatory is a facility of the National Science Foundation operated under cooperative agreement by Associated Universities=2C Inc.
