We performed R band imaging observations around the error circle of
GRB 161014A (Racusin et al., GCN 20035) with the optical imager HOWPol
attached to Kanata telescope of Hiroshima University. The observation
was made at 2016-10-14 12:32:48 UT (mid time of the observation). We
detected the optical transient reported by Morita et al. (GCN 20036),
Guidorzi et al. (GCN 20037) and Xin et al. (GCN 20038) in our R-band
image. The detected magnitude and five sigma upper limit (in Vega
magnitude) of the OT are listed below.
