GCN 10628) with the Expanded Very Large Array (EVLA) on May 1.50 UT \nat a center frequency of 8.46 GHz.  We do not detect any radio source\nanywhere within the refined XRT error circle (Beardmore et al., GCN 10638)\nto a 3-sigma limit of 51 uJy.\n\nThe EVLA is still undergoing active commissioning and we caution that\nthese results should be considered preliminary.  The National Radio\nAstronomy Observatory is a facility of the National Science Foundation\noperated under cooperative agreement by Associated Universities, Inc.\"",
