GRB 160104A: Nishi-Harima MINT Observations

K. Morihana. J. Takahashi, Y. Takagi, S. Honda, T. Ohshima, and Y. Itoh
(Univ. of Hyogo), report on behalf of Nayuta team and OISTER collaboration:

We observed the field of GRB 160104A (Melandri et al. GCN 18815)
with Multiband Imager for Nayuta Telescope (MINT) attached to the Nayuta 2-m
telescope at the Nishi-Harima Astronomical Observatory.

The observations were started at 12:01 UT on 2016-01-4 (~35 minuets
after the burst).
We detected the optical afterglow in Rc band within the error circle of
Swift/XRT.

Photometric results of our observations are shown below.
We used nearby NOMAD catalogue stars for the photometric calibration.
