G. B. Taylor (NRAO) and E. Berger (Caltech) report on behalf of a
larger collaboration:
"Beginning on December 18.16 UT we observed the field containing the
bright BATSE burst GRB 991216 (Kippen et al. GCN 463) using the VLA at
8.5 GHz. We detect a 938 +/- 60 microJy radio source coincident with
the optical transient reported by Uglesich et al. (GCN 472). No other
radio sources are detected within 2 arcminutes above a 5sigma flux
density limit of 300 microJy. The radio afterglow is at
ra = 05h09m31.297s dec = +11d17'07.25" (equinox J2000) with a conservative
error of 0.1 arcsec in each coordinate. Additional radio observations
with the VLA and VLBA are planned."
