Kawai(Tokyo Tech.) on behalf of the J-GEM\ncollaboration.\n\nWe carried out J-band imaging observations of 32 nearby galaxies to\nsearch for new point sources associated with the objects, in response\nto G194575. The target galaxies were selected from nearby galaxies\nlisted in GWGC, close to the anti-solar direction.\n\nThe observations were made on 23rd and 24th October 2015, with a\nwide-field infrared camera (D=0.91 m), OAOWFC, of Okayama Astrophysical\nObservatory of NAOJ.\n\nWe could find no new point sources brighter than the limiting magnitude\nof J=17-18(S/N=3) in Vega system. The photometric calibration was made\nagainst 2MASS field stars.\n\nSummary of the observations are listed below.\n\n#-----------------------------------------\n#Object    UT Start         Exp  Limit J\n#                          (min)  (S/N=3)\n#-----------------------------------------\nUGC00637   2015-10-23 09:15  15    17.2\nPGC003718  2015-10-23 09:35  20    17.5\nUGC00656   2015-10-23 10:02  15    17.7\nIC0073     2015-10-23 10:22  15    17.6\nIC1613     2015-10-23 10:42  15    17.8\nUGC00667   2015-10-23 11:02  15    17.9\nIC0074     2015-10-23 11:22  15    18.1\nUGC00678   2015-10-23 11:41  29    18.2\nPGC1238390 2015-10-23 12:42  13    18.1\nUGC00711   2015-10-23 13:50  20    18.4\nPGC1245956 2015-10-23 14:17  15    18.3\nPGC004199  2015-10-23 14:37  15    18.2\nIC0052     2015-10-23 14:57  15    18.2\nUGC00526   2015-10-23 15:17  15    18.2\nUGC00527   2015-10-23 15:37  15    18.2\nUGC00537   2015-10-23 15:57  15    18.2\nPGC1232627 2015-10-23 16:17  15    18.2\nIC1592     2015-10-23 16:36  15    18.2\nPGC003137  2015-10-23 16:56  15    18.1\nUGC00544   2015-10-23 17:16  15    17.8\nPGC003199  2015-10-23 17:36  15    17.9\nIC1598     2015-10-23 17:56  15    17.7\nUGC00574   2015-10-23 18:16  15    17.6\nPGC1177707 2015-10-23 18:36  09    17.1\nPGC003495  2015-10-24 09:56  15    17.7\nPGC003500  2015-10-24 10:16  15    17.9\nPGC003524  2015-10-24 10:36  15    17.9\nPGC003530  2015-10-24 10:56  15    17.9\nUGC00618   2015-10-24 11:16  15    17.7\nPGC003600  2015-10-24 11:36  15    17.9\nUGC00637   2015-10-24 11:55  15    18.0\nPGC003718  2015-10-24 12:15  15    17.8\n#-----------------------------------------",
