GCN Circular 6982
P. Chandra (UVA/NRAO) and D. A. Frail (NRAO) report on behalf of the Caltech-NRAO-Carnegie GRB Collaboration: "We observed the field centered on the XRT position of the Swift burst GRB 071021 (GCN 6958) using the VLA at a frequency of 8.46 GHz. The observations were taken at a mean time of 06.11 UT on 23nd Oct 07. We detect possible radio afterglow of GRB 071021 in agreement with NIR position (GCN # 6971) and the Swift-XRT afterglow position (GCN # 6963). Our 3-sigma detection yields the flux value of 149+/-44 uJy at the following position: RA(J2000) 22 42 34.25 Dec(J2000) +23 43 06.36 The National Radio Astronomy Observatory is a facility of the National Science Foundation operated under cooperative agreement by Associated Universities, Inc."
