(Stanford/SLAC), on behalf of J-GEM collaboration\n\nWe report optical follow-up observations for a bright optical transient (V.\nLipunov al., GCN Circ. 26379) inside LVC 191205ah error region (The LIGO\nScientific Collaboration and the Virgo Collaboration, GCN Circ. 26350).\n\nWe observed the OT using 50 cm MITSuME telescope at Akeno Observatory using\na 3 color imager in g', Rc, Ic starting at 19:09:08 (UT) on 2019-12-07. We\nconfirmed the position of the OT is consistent with GCN Circ. 26379.\nOur photometry results with an integration time of 1080 sec are:\ng' 17.7 +/- 0.1\nRc 17.9 +/- 0.1\nIc 18.6 +/- 0.2\nin AB magnitude system calibrated by PanSTARRS photometry of nearby stars.",
