TITLE: GCN CIRCULAR NUMBER: 16296 SUBJECT: GRB 140516A: Subaru NIR imaging observations DATE: 14/05/18 03:49:48 GMT FROM: Nobuyuki Kawai at Tokyo Tech Y. Minowa, T.-S. Pyo, J.-H. Kim (Subaru, NAOJ) and N. Kawai (Tokyo Tech) report on behalf of the Subaru GRB team: We observed the field of the short GRB 140516A (Bernardini et al., GCN 16285) using IRCS+AO188 on the 8.2 m Subaru telescope, starting from 06:56 on May 17, 2014 UTC (about 10.4 hrs from the burst). We obtained the Kp-band images in 52 mas/pixel mode without AO correction for a total exposure time of 5880 sec under 0".7 seeing condition. We do not detect any source within the error circle reported by Osborne et al. (GCN 16289). We obtained the 3-sigma limit on the near-infrared afterglow of GRB 140516A of Kp>22.2 mag (Vega) at 10.4-12.7 hrs after the burst.
