TITLE: GCN CIRCULAR NUMBER: 15200 SUBJECT: GRB 130907A: VLA detection DATE: 13/09/08 22:25:42 GMT FROM: Alessandra Corsi at GWU A. Corsi (GWU) reports on behalf of a larger collaboration: We imaged the position of GRB 130907A (Page et. al. GCN 15183) with the Karl G. Jansky Very Large Array (VLA) in K-band, starting at about 4 hours after the burst. A provisional reduction shows a source consistent with the location of the GRB optical afterglow reported by de Ugarte Postigo et al. (GCN 15187). At this time, we estimate a preliminary flux of about 1.2 mJy at 24.5 GHz. Further observations are planned.
