TITLE: GCN GRB OBSERVATION REPORT NUMBER: 3933 SUBJECT: GRB 050906: Radio Observations DATE: 05/09/06 19:12:44 GMT FROM: Dale A. Frail at NRAO P. B. Cameron (Caltech) and D. A. Frail (NRAO) report on behalf of a larger collaboration: "We have undertaken two short (~20 min) VLA observations at a frequency of 8.46 GHz toward the BAT error circle of GRB 050906 (GCN 3926) on Sept. 6.52 UT and Sept. 6.58. There is a single radio source displaced about 1 arcmin north of IC328 at a position (J2000): RA = 03:31:11.75 DEC=-14:37:18.1 The astrometry error at this point is +/-0.5 arcsec. The source did not vary significantly between the two epochs separated by ~1.4hrs. Further observations are planned to determine. Further observations are planned.
