TITLE: GCN CIRCULAR NUMBER: 25377 SUBJECT: LIGO/Virgo S190814bv: No candidates found in J-GEM follow-up observations DATE: 19/08/17 00:36:41 GMT FROM: Yousuke Utsumi at Hiroshima Astrophys. Science Center Nakaoka, T.; Sasada, M. (Hiroshima U.); Adachi, R.; Yatsu, Y.; Murata, K. L. (Tokyo Tech.); Yanagisawa, K.; Yoshida, M. (NAOJ); Onozato, H. (Nishi-Harima Astronomical Observatory); Tanaka, M. (Tohoku U.); Morokuma, T (U. Tokyo); Utsumi, Y. (Stanford/SLAC) on behalf of J-GEM collaboration We report galaxy-targeted observations for the gravitational wave event S190814bv (Mo et al, GCN Circ. 25324). We started our observations from 2019-08-16 15:21 UT about 1.7 days after the event and ended at 2019-08-16 19:12 UT. We performed galaxy-targeted observations for 31 galaxies (see the table below) selected from the GLADE catalog (Dalya et al. 2018) in the probability skymap of S190814bv using the following telescopes and instruments. We found no apparent transient objects in these galaxies to 5 sigma limiting magnitudes in AB listed below. galid ra dec G R I J H obsid --------------- ------- -------- ---- ---- ---- ---- ---- ------------- GL004822-250737 12.0911 -25.1268 -- 19.3 -- -- 19.1 Kanata-HONIR GL005130-243833 12.8744 -24.6425 14.7 12.9 13.7 -- -- MITSuME-Akeno GL005242-254402 13.1733 -25.7339 -- 18.3 -- -- 18.8 Kanata-HONIR GL004843-234623 12.1782 -23.7731 -- 19.0 -- -- 19.6 Kanata-HONIR GL005010-231648 12.5404 -23.28 -- -- -- 16.5 -- OAOWFC GL005033-231744 12.6379 -23.2955 -- -- -- 16.5 -- OAOWFC GL004915-235131 12.3111 -23.8585 -- 19.0 -- -- 19.6 Kanata-HONIR GL004917-261309 12.3201 -26.2192 -- -- -- 18.1 -- OAOWFC GL005215-244155 13.064 -24.6987 14.7 12.9 13.7 -- -- MITSuME-Akeno GL005033-230100 12.6392 -23.0166 -- -- -- 16.5 -- OAOWFC GL004058-220500 10.2428 -22.0831 -- 18.4 -- -- 19.1 Kanata-HONIR GL005115-231730 12.811 -23.2916 -- -- -- 16.5 -- OAOWFC GL004923-263027 12.3463 -26.5075 -- -- -- 18.1 -- OAOWFC GL004933-263219 12.3856 -26.5386 -- -- -- 18.1 -- OAOWFC GL005045-232020 12.6863 -23.3388 -- -- -- 16.5 -- OAOWFC GL005247-254018 13.1945 -25.6716 -- 18.3 -- -- 18.8 Kanata-HONIR GL004920-262835 12.332 -26.4764 -- -- -- 18.1 -- OAOWFC GL005116-231740 12.8152 -23.2944 -- -- -- 16.5 -- OAOWFC GL004934-263624 12.3936 -26.6067 -- -- -- 18.1 -- OAOWFC GL004918-262834 12.3237 -26.4761 -- -- -- 18.1 -- OAOWFC GL004708-242214 11.7814 -24.3706 -- 18.0 -- -- 18.5 Kanata-HONIR GL004922-261533 12.3437 -26.2592 -- -- -- 18.1 -- OAOWFC GL004934-261716 12.3924 -26.2878 -- -- -- 18.1 -- OAOWFC GL004843-233342 12.1804 -23.5617 -- 19.3 -- -- 20.1 Kanata-HONIR GL004729-252626 11.8706 -25.4407 -- 19.3 -- -- 18.5 Kanata-HONIR GL004928-263218 12.3648 -26.5383 -- -- -- 18.1 -- OAOWFC GL005001-261807 12.5046 -26.302 -- -- -- 18.1 -- OAOWFC GL004914-263121 12.3096 -26.5224 -- -- -- 18.1 -- OAOWFC GL004946-262635 12.4418 -26.443 -- -- -- 18.1 -- OAOWFC GL004901-234841 12.2562 -23.8113 -- 19.0 -- -- 19.6 Kanata-HONIR GL005424-252751 13.6014 -25.4641 -- 17.6 -- -- 19.1 Kanata-HONIR Kanata-HONIR: 150 cm Kanata telescope at Higashi-Hiroshima Observatory and HONIR -- a 2 channel imager (Rc and H) (Akitaya et al. 2014, Proc.
