TITLE: GCN CIRCULAR NUMBER: 20267 SUBJECT: IceCube-161210: Kanata/HONIR near-infrared follow-up observation DATE: 16/12/15 07:21:21 GMT FROM: Michitoshi Yoshida at HASC,Hiroshima U Hiroki Mori, Yousuke Utsumi, Yasuyuki T. Tanaka, Koji S. Kawabata, Kensei Shiki, Taisei Abe, Michitoshi Yoshida (Hiroshima University) on behalf of Kanata team We performed J-band tiling observations for the ~40'x40' region centered at the IceCube alert R.A.=46.58 deg and Dec.=14.98 deg (Blaufuss, GCN 20247) with the optical-infrared simultaneous camera HONIR attached to 1.5m Kanata telescope of Hiroshima University from 13 to 17.5 UT on December 11, 2016. Compared our data with 2MASS catalog, we found no bright NIR transient in the observed region. 5 sigma limiting magnitude was J=18.8 (preliminary, 2'' aperture). We also obtained R-band data simultaneously, and the data analysis is ongoing.
