Chandra (UVA/NRAO)\nreport on behalf of the Caltech-NRAO-Carnegie GRB Collaboration:\n\n\"We re-observed the field of GRB 051109B (GCN 4222) centered on the \nrevised XRT position (GCN 5387) using the VLA on August 9.5 UT 2006 (t~9 \nmonths after the burst) at a frequency of 1.43 GHz.  Comparison with our \nprevious VLA observations (GCN 4245) reveals no new sources within the \nrevised XRT error circle.  We place a 3-sigma limit of 0.21 mJy. \nAdopting a redshift of z=0.08 for the putative host galaxy (GCN 5387), \nthis limit corresponds to a radio luminosity 100 times fainter than that \nobserved for GRB 030329 at a comparable epoch (Frail et al. 2003, ApJ, \n619, 944).\n\nThe National Radio Astronomy Observatory is a facility of the National\nScience Foundation operated under cooperative agreement by Associated\nUniversities, Inc.\"",
