TITLE: GCN CIRCULAR NUMBER: 4199 SUBJECT: GRB 051105A, radio observations DATE: 05/11/06 00:07:00 GMT FROM: Dale A. Frail at NRAO D. A. Frail (NRAO) and P. B. Cameron (Caltech) report on behalf of a larger collaboration: "We observed the field of GRB 051105A (GCN 4188; GCN 4194) with the Very Large Array at 8.5 GHz beginning November 5.80 UT. Within the �2.5 arcmin BAT error radius we find one radio source in excess of 5-sigma with a flux density of 190 � 17 uJy at RA(J2000)=17 41 3.19 DEC(J2000) = +34 59 04.1, with (conservative) astrometric errors of order 1 arcsec. There are no radio sources at the positions of the four XRT sources listed in GCN 4195. Given the relatively large size of the BAT error circle, and the lack of any flux variations we cannot determine whether this radio source is related to GRB 051105A. Further observations are planned. The National Radio Astronomy Observatory is a facility of the National Science Foundation operated under cooperative agreement by Associated Universities, Inc." [GCN OPS NOTE(10dec06): The burst name in the Subject-line was changed from "051005A" to "051105A" to agree with the contents of the Circular.]
