Dale A. Frail (NRAO) and Poonam Chandra (RMC) report on behalf of a
larger collaboration:
"We observed the localization of dark burst GRB 100420A (Baumgartner
et al. GCN 10628) with the Expanded Very Large Array (EVLA) on May 1.50 UT
at a center frequency of 8.46 GHz. We do not detect any radio source
anywhere within the refined XRT error circle (Beardmore et al., GCN 10638)
to a 3-sigma limit of 51 uJy.
The EVLA is still undergoing active commissioning and we caution that
these results should be considered preliminary. The National Radio
Astronomy Observatory is a facility of the National Science Foundation
operated under cooperative agreement by Associated Universities, Inc."
