TITLE: GCN CIRCULAR NUMBER: 9166 SUBJECT: VLA radio detection of GRB 090418 DATE: 09/04/19 23:59:16 GMT FROM: Poonam Chandra at U Virginia/NRAO Poonam Chandra (RMC) and Dale A. Frail (NRAO) report on behalf of a larger collaboration: "We used the Very Large Array to observe the field of view toward the GRB 090418 (GCN 9149) at a frequency of 8.46 GHz on 2009 Apr.19.46 UT. We observed the radio afterglow of the GRB at a position J2000 RA 17:57:15.156, Dec 33:24:20.78 which is 0.39" away from the KAIT optical afterglow position reported by Chornock et al. (GCN 9148).
