"We used the Very Large Array to observe the Swift burst GRB051221B
(GCN 4376; GCN 4382) at a frequency of 8.46 GHz on 2005 Dec. 27.92 UT
(i.e. 6.9 days after the burst). No radio emission is detected within
the XRT error circle (GCN 4378). The rms noise was 31 uJy.

No further observations are planned.

The National Radio Astronomy Observatory is a facility of the National
Science Foundation operated under cooperative agreement by Associated
