collaboration
We conducted optical imaging observations of nearby galaxies within
the probability skymap of G275404 (LVC; GCN 20738) with the 50cm
MITSuME telescopes at Akeno Observatory and Okayama Astrophysical
Observatoty (OAO) and the 91cm wide field near-infrared camera
(OAOWFC) at OAO in the framework of J-GEM collaboration. We obtained
optical three color data, g', Rc, and Ic, with MITSuME. Near-infrared
J-band data were obtained with OAOWFC.
The 5-sigma limiting AB magnitudes are listed below.
No optical/infrared transient source corresponding to the GW event
was found by these observations.
