"We observed the field of GRB 051008 (GCN 4069) with the Very Large Array
at 8.5 GHz beginning October 8.86 UT (~4 hours after the burst). No radio
source is detected within the XRT error circle (GCN 4073) with a 2-sigma
upper limit of 80 uJy.
We find one source above the 4-sigma level in the BAT error circle at
RA(J2000) 13:31:22.92 +/- 0.07
DEC +42:04:31.7 +/- 0.3
with a flux density of 175 +/- 40 uJy. However, the probability of finding
a source of this brightness in a region with 3-arcmin radius is ~54%
(Fomalont et al., 2002, ApJ, 123, 2402).
