K. Yanagisawa, D. Kuroda (OAO/NAOJ), Y. Utsumi, M. Yoshida (Hiroshima),
K. Ohta(Kyoto) and N. Kawai(Tokyo Tech.) on behalf of the J-GEM
collaboration.

We carried out J-band imaging observations of 32 nearby galaxies to
search for new point sources associated with the objects, in response
to G194575. The target galaxies were selected from nearby galaxies
listed in GWGC, close to the anti-solar direction.

The observations were made on 23rd and 24th October 2015, with a
wide-field infrared camera (D=0.91 m), OAOWFC, of Okayama Astrophysical
Observatory of NAOJ.

We could find no new point sources brighter than the limiting magnitude
of J=17-18(S/N=3) in Vega system. The photometric calibration was made
against 2MASS field stars.

Summary of the observations are listed below.
