TITLE: GCN CIRCULAR NUMBER: 16516 SUBJECT: GRB 140703A: VLA K-band detection DATE: 14/07/04 02:51:36 GMT FROM: Alessandra Corsi at GWU A. Corsi (GWU / TTU) reports on behalf of a larger collaboration: We imaged the position of GRB 140703A (Kocevski et al., GCN 16503) with the Karl G. Jansky Very Large Array (VLA) in K-band, starting at about 8.5 hours after the burst. A provisional reduction shows a source consistent with the location of the GRB X-ray and optical afterglows (Goad et al., GCN 16506; Cunniffe et al., GCN 16504). At this time, we estimate a preliminary flux of about 280 uJy at 19 GHz. Further observations are planned.
