TITLE: GCN CIRCULAR NUMBER: 18740 SUBJECT: LIGO/Virgo G211117: Optical follow-up with Kanata telescope DATE: 15/12/29 01:05:29 GMT FROM: Michitoshi Yoshida at J-GEM R. Itoh, Y. Utsumi, T. Nakaoka, M. Kawabata, M. Yoshida (HASC, Hiroshima Univ.) on behalf of J-GEM collaboration We observed nearby galaxies listed in GWGC in the error area of the G211117 with HOWPol (15 arcmin FOV optical imager) attached to the 1.5m Kanata telescope on 2015-12-27 (UTC). We performed R and I bands imaging observations. No optical transient brighter the upper limits of the observed fields was detected in both bands. The observed objects and 3-sigma upper limits are listed below. #Time(UT) exposure[sec] ra[deg.] width[arcrmin] dec[deg.] #width[arcmin] R-Upperlimit(3-sigma) I-Upperlimit(3-sigma) Object #----------------------------------------------------------------- 2015-12-27T18:10:18 90.0 57.7208 10 39.7889 10 19.2 19.2 PGC097021 2015-12-27T18:30:56 90.0 49.2417 10 31.5672 10 17.6 17.7 UGC02627 2015-12-27T18:38:03 90.0 52.8250 10 35.4661 10 18.2 17.9 UGC02770 2015-12-27T18:48:39 90.0 53.3042 10 36.1842 10 18.3 18.0 UGC02780 2015-12-27T18:59:12 90.0 53.6958 10 36.2097 10 18.6 18.6 UGC02788 2015-12-27T19:09:49 90.0 55.3833 10 37.2256 10 17.8 18.2 UGC02817 2015-12-27T19:20:21 90.0 57.0375 10 37.4569 10 17.8 17.7 PGC165376 2015-12-27T19:31:01 90.0 58.2333 10 40.1125 10 18.8 18.9 PGC097023 2015-12-27T19:42:15 90.0 207.9833 10 -29.7647 10 18.2 18.2 PGC725406 2015-12-27T19:57:26 90.0 208.1917 10 -29.9297 10 18.4 18.4 ESO445-065 2015-12-27T20:07:55 90.0 208.4333 10 -30.5281 10 18.5 18.6 PGC089791 2015-12-27T20:18:23 90.0 208.5958 10 -30.3797 10 18.4 18.4 PGC089797 2015-12-27T20:29:00 90.0 208.3292 10 -30.6975 10 18.4 18.5 PGC714066 2015-12-27T20:39:39 90.0 208.4833 10 -30.9794 10 18.7 18.7 PGC089792 2015-12-27T20:50:13 90.0 208.5875 10 -31.1817 10 19.0 18.8 PGC184225 2015-12-27T21:00:47 90.0 208.6417 10 -31.4703 10 18.6 18.7 PGC089799 2015-12-27T21:11:22 90.0 209.6125 10 -31.7761 10 18.2 17.7 ESO445-085 2015-12-27T21:21:57 90.0 209.1333 10 -32.4886 10 16.5 -- PGC690995
