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.
