(Stanford/SLAC) on behalf of\nJ-GEM collaboration\n\nWe report imaging observations for the gravitational wave event S190814bv\n(Mo et al, GCN Circ. 25324). We began our first set of observations and\nreported in Nakaoka et al., GCN Circ. 25377. This report is the second set\nof observations from 2019-08-17 14:05 UT  about 2.7 days after the event\nand ended at 2019-08-17 18:32 UT.\n\nWe performed galaxy-targeted observations for 23 galaxies (see the table\nbelow) selected from the GLADE catalog (Dalya et al. 2018) in the\nprobability skymap of S190814bv using the following telescopes and\ninstruments.\n\nWe found no apparent transient objects in these galaxies to 5 sigma\nlimiting magnitudes in the AB system listed below.\n\n    galid         ra dec   g r R i    z J H     obsid\n\n--------------- -------- -------- ---- ---- ---- ---- ---- ---- ----\n--------------------------\n\nGL004822-250737 12.0911  -25.1268 18.9 19.4 19.3 18.7 --   -- 19.1\nBandC-Tripol\n\nGL005130-243833 12.8744  -24.6425 99.9 99.9 12.9 99.9 --   -- --\nBandC-Tripol\n\nGL005242-254402 13.1733  -25.7339 99.9 99.9 18.3 99.9  --   -- 18.9\nBandC-Tripol,Kanata-HONIR\n\nGL004705-241419 11.7719  -24.2387 13.6 19.2 -- 18.3 99.9 --   --\nSaCRA-MuSaSHI,BandC-Tripol\n\nGL005111-255715 12.7938  -25.9542 19.3 19.5 -- 18.8 --   -- --\nBandC-Tripol\n\nGL005119-261005 12.8282  -26.1681 19.3 15.0 -- 13.2 --   -- --\nBandC-Tripol\n\nGL004242-214627 10.6763  -21.7741 -- -- 17.5 --   -- -- 17.3\nKanata-HONIR\n\nGL004915-235131 12.3111  -23.8585 99.9 99.9 19.0 99.9 --   -- 19.6\nBandC-Tripol\n\nGL004858-254136 12.2428  -25.6934 19.3 19.3 -- 18.8 --   -- --\nBandC-Tripol\n\nGL004855-250410 12.229   -25.0695 19.4 19.6 -- 18.3 --   -- --\nBandC-Tripol\n\nGL004923-263027 12.3463  -26.5075 19.6 19.4 -- 18.2 --   18.1 --\nBandC-Tripol\n\nGL004933-263219 12.3856  -26.5386 19.6 19.4 -- 18.2 --   18.1 --\nBandC-Tripol\n\nGL235701-344533 359.2529 -34.7592 --   -- 18.9 -- -- -- 18.9\nKanata-HONIR\n\nGL005247-254018 13.1945  -25.6716 -- -- 18.3 --   -- -- 18.9\nKanata-HONIR\n\nGL004240-214801 10.6664  -21.8002 -- -- 17.5 --   -- -- 17.3\nKanata-HONIR\n\nGL005116-255739 12.8157  -25.9609 19.3 19.5 -- 18.8 --   -- --\nBandC-Tripol\n\nGL005103-255857 12.7644  -25.9824 19.3 19.5 -- 18.8 --   -- --\nBandC-Tripol\n\nGL012733-044059 21.8892  -4.6829 -- -- 19.4 --   -- -- 18.6\nKanata-HONIR\n\nGL004610-251248 11.5434  -25.2132 -- -- -- --   -- 18.0 --\nOAOWFC\n\nGL013640-012345 24.166   -1.3958 -- -- 17.4 --   -- -- 16.9\nKanata-HONIR\n\nGL004729-252626 11.8706  -25.4407 99.9 99.9 19.3 16.9 --   18.0 18.5\nBandC-Tripol,OAOWFC\n\nGL004928-263218 12.3648  -26.5383 19.6 19.4 -- 18.2 --   18.1 --\nBandC-Tripol\n\nGL235701-344050 359.2528 -34.6806 --   -- 18.9 -- -- -- 18.9\nKanata-HONIR\n\nBandC-Tripol: 61 cm Boller & Chivens telescope at Mt.
