TITLE: GCN CIRCULAR NUMBER: 18742 SUBJECT: LIGO/Virgo G211117: Optical NIR observation with Kanata telescope DATE: 15/12/29 01:56:22 GMT FROM: Michitoshi Yoshida at J-GEM R. Itoh, Y. Kanda, M. Yoshida, Y. Utsumi, K. S. Kawabata, M. Uemura, T. Nakaoka, M. Kawabata (HASC, Hiroshima Univ.), M. Tanaka (NAOJ) on behalf of J-GEM collaboration We observed nearby galaxies listed in GWGC in the error area of the G211117 with HONIR (7 arcmin FOV optical near-infrared 2 color simultaneous imager & spectrograph) attached to the 1.5m Kanata telescope on 2015-12-28 (UTC). We performed I and J bands imaging observations. We found a transient point source in the field of UGC 1410 at 2015-12-28 13:42 (UTC). The object was clearly detected both in I and J. The position and I band magnitude of this object are RA 01:56:17.6 DEC +04:33:08 17.3 ± 0.2 (I). The position is consistent with that of the SDSS J015617.19+043307.7 whose i band magnitude is 22.12 (SDSS DR10). The OT we found is about 100 times brighter than this SDSS object. Spectroscopic follow-up is encouraged. The observed galaxies and the 3-sigma I-band limiting magnitudes are listed below. #Time(UT) exposure ra[deg.] width[arcrmin] dec[deg.] width[arcmin] #I-Upperlimit(3-sigma) Object #----------------------------------------------------------------- 2015-12-28T09:00:44 120.0 31.1792 7 8.5431 7 19.4 UGC01572 2015-12-28T09:14:04 120.0 29.5250 7 5.7689 7 20.7 PGC1288823 2015-12-28T09:27:33 120.0 34.4042 7 12.5089 7 -- IC1790 2015-12-28T09:41:06 120.0 35.3792 7 14.1986 7 19.0 UGC01817 2015-12-28T09:55:28 120.0 32.2758 7 1.6333 7 19.8 J020905.98+013800.5 2015-12-28T10:35:37 120.0 38.7912 7 20.8525 7 20.6 UGC02064 2015-12-28T10:49:12 120.0 26.9542 7 0.3039 7 -- PGC1146688 2015-12-28T11:02:32 120.0 26.7250 7 0.6139 7 -- PGC1138988 2015-12-28T11:28:11 120.0 28.6708 7 0.6114 7 -- PGC1170628 2015-12-28T11:42:03 120.0 45.5333 7 29.1081 7 20.7 UGC02497 2015-12-28T11:55:44 120.0 27.8500 7 1.6961 7 19.8 PGC1202981 2015-12-28T12:09:06 120.0 29.5167 7 2.0436 7 -- [RGK2003]J015804.70+020237.4 2015-12-28T12:22:23 120.0 29.4083 7 2.4231 7 20.8 PGC007383 2015-12-28T12:35:42 120.0 29.0542 7 3.4886 7 19.4 PGC007248 2015-12-28T12:49:00 120.0 29.6417 7 3.2569 7 20.1 UGC01454 2015-12-28T13:02:16 120.0 29.5083 7 3.3692 7 17.6 UGC01446 2015-12-28T13:15:30 120.0 29.5042 7 3.4539 7 19.9 PGC007442 2015-12-28T13:28:45 120.0 29.0667 7 3.7617 7 19.9 IC0174 2015-12-28T13:42:06 120.0 29.0667 7 4.6469 7 21.0 UGC01410 2015-12-28T14:00:13 120.0 29.4958 7 4.3950 7 19.9 UGC01444 2015-12-28T14:13:38 120.0 29.2833 7 4.5644 7 20.9 PGC007331 2015-12-28T14:26:52 120.0 29.0250 7 4.9969 7 20.6 PGC007225 2015-12-28T14:40:08 120.0 29.1375 7 5.2150 7 19.2 PGC007276 2015-12-28T14:53:20 120.0 29.7083 7 5.3597 7 17.3 PGC007476 2015-12-28T15:06:35 120.0 29.7208 7 5.4175 7 19.8 PGC007477 2015-12-28T15:19:58 120.0 30.8958 7 4.7856 7 17.3 UGC01553 2015-12-28T15:50:04 120.0 38.1708 7 15.7192 7 20.7 PGC089526 2015-12-28T16:03:20 120.0 40.2500 7 17.4311 7 19.1 UGC02168 2015-12-28T16:16:55 120.0 38.2208 7 19.2581 7 -- PGC009699 2015-12-28T16:30:12 120.0 39.7667 7 18.3939 7 17.7 PGC010042 2015-12-28T16:43:30 120.0 42.3125 7 21.3047 7 --- PGC089527 2015-12-28T16:56:49 120.0 43.8000 7 24.6347 7 19.0 PGC011015 2015-12-28T17:10:05 120.0 45.5167 7 25.7933 7 17.8 PGC090653 2015-12-28T17:23:33 120.0 52.8250 7 35.4661 7 19.6 UGC02770 2015-12-28T17:36:47 120.0 53.2083 7 36.2186 7 19.5 UGC02778 2015-12-28T17:50:10 120.0 53.3042 7 36.1842 7 17.7 UGC02780 2015-12-28T18:03:31 120.0 55.3833 7 37.2256 7 17.7 UGC02817 2015-12-28T18:16:48 120.0 56.7417 7 38.6342 7 18.4 UGC02857 2015-12-28T18:30:12 120.0 57.7208 7 39.7889 7 18.1 PGC097021 2015-12-28T19:01:50 120.0 70.3417 7 45.8281 7 18.6 PGC3094748 2015-12-28T19:15:12 120.0 68.9917 7 47.7172 7 19.3 PGC3094741 2015-12-28T19:28:31 120.0 69.5625 7 48.6942 7 19.3 PGC015704 2015-12-28T19:41:56 120.0 76.5833 7 50.8417 7 20.9 PGC097073 2015-12-28T19:55:20 120.0 84.9333 7 52.6019 7 19.8 PGC2816495 2015-12-28T20:08:46 120.0 84.4417 7 54.1625 7 17.3 PGC090015 2015-12-28T20:22:13 120.0 92.7792 7 55.3381 7 -- PGC090750 2015-12-28T20:35:34 120.0 103.2917 7 57.1778 7 17.9 UGC03574 2015-12-28T20:48:56 120.0 105.9958 7 56.4861 7 20.1 PGC020086
