They represent the 3.3% of all galaxies within 40.0 Mpc in the Glade catalogue within the LVC error region for the GW trigger and contains 13.3% of all B band luminosity of those galaxies. We started to observe these sample of galaxies on 2017-5-2 and monitored them for 2 weeks after the GW trigger. No interesting transients have been identified down to a limit magnitude of 19.\n\nBelow follow the list of galaxies observed:\nName RA(J2000) DEC(J2000) Dist(Mpc) BMAG KMAG\nNGC6384 263.1007 7.0603 25.94 -21.26 -24.5418\nIC4837A 288.8173 -54.1325 33.42 -21.15 -24.474\nNGC6788 291.7071 -54.9513 34.56 -21.09 -24.1729\nNGC6181 248.0877 19.8259 33.57 -20.73 -23.9578\nIC4837 288.808 -54.6659 33.42 -20.72 -20.383\nNGC6368 261.7978 11.5436 30.48 -20.62 -23.2311\nNGC7049 319.7449 -48.5632 29.92 -20.61 -25.1338\nNGC6887 304.3219 -52.7968 30.06 -20.49 -23.5189\nNGC6868 302.4754 -48.3796 26.79 -20.45 -24.8229\nNGC6810 295.8931 -58.6557 23.12 -20.42 -24.1399\nIC4889 296.3133 -54.3442 29.24 -20.33 -24.2199\nNGC6861 301.8312 -48.3703 28.05 -20.29 -24.5317\nNGC7029 317.967 -49.2838 38.37 -20.23 -24.38\nIC4797 284.1237 -54.3059 28.05 -20.23 -24.1707\nNGC6851 300.8932 -48.2845 36.14 -20.13 -24.0209\nIC4946 305.992 -43.9953 34.67 -20.12 -23.9688\nESO183-030 284.2327 -54.5457 33.42 -20.11 -24.292\nNGC7041 319.1349 -48.3636 25.7 -20.06 -23.8377\nNGC6909 306.9121 -47.027 35.48 -20.04 -23.5259\nIC4839 288.8919 -54.6266 35.11 -20.02 -23.4762\nNGC6870 302.5452 -48.2871 33.42 -19.9 -23.673\nNGC6509 269.8555 6.287 27.67 -19.81 -22.476\nNGC7007 316.3662 -52.5519 34.67 -19.75 -23.7408\nESO231-017 286.1934 -47.8487 35.14 -19.62 -23.204\nIC4901 298.5957 -58.7139 17.86 -19.61 -22.4144\nNGC6890 304.5756 -44.8071 31.19 -19.52 -23.4431\nNGC6875A 302.9827 -46.1441 29.11 -19.52 -22.3472\nNGC6889 304.7221 -53.957 30.22 -19.49 -22.0095\nIC1151 239.6347 17.4415 24.21 -19.38 -21.508\nESO234-049 308.8254 -49.8655 31.19 -19.33 -21.8731\nUGC11093 270.4656 6.9683 21.18 -19.23 -22.2496\nUGC10862 262.0374 7.4226 25.35 -19.22 -20.3179\nESO286-063 317.4682 -45.5276 31.81 -19.21 -21.9048\nESO186-062 308.5086 -52.9812 31.19 -19.1 -22.2241\nIC4986 304.2982 -55.0364 23.75 -19.08 -19.9153\nUGC11030 268.6407 2.8794 27.67 -19.06 -19.63\nESO340-032 306.7336 -39.6159 33.54 -18.98 -21.1668\nIC4821 287.3833 -55.0173 25.0 -18.98 -21.6087\nIC4817 286.5516 -56.1594 33.42 -18.96 -21.27\nNGC6861D 302.0812 -48.2114 33.42 -18.9 -23.421\nNGC6707 283.8415 -53.8186 33.42 -18.9 -22.969\nESO340-010 304.3582 -41.1334 39.26 -18.82 -22.1218\nIC4871 293.9259 -57.5191 22.59 -18.8 -20.8786\nESO285-048 311.1676 -45.9786 28.18 -18.77 -21.3327\nESO185-027 299.0568 -56.9106 23.81 -18.73 -21.9358\nNGC6902B 305.7795 -43.8686 34.67 -18.69 -20.7538\nESO236-006 320.2867 -47.5151 28.93 -18.66 -19.5207\nNGC6149 246.8508 19.5972 30.57 -18.65 -22.1455\nNGC6990 314.9871 -55.562 25.36 -18.57 -21.0847\nESO233-035 302.3566 -48.2848 33.97 -18.57 -22.2335\nNGC7090 324.1204 -54.5576 6.28 -18.56 -20.8258\nNGC6861E 302.7564 -48.6908 33.9 -18.55 -21.044\nESO235-085 319.5675 -48.5375 24.03 -18.53 -21.6278\nNGC7022 317.3967 -49.3037 29.49 -18.51 -22.1184\nESO235-001 312.2578 -47.2987 33.75 -18.51 -20.2164\nPGC061359 271.0942 7.2804 28.11 -18.5 -23.0103\nIC4885 295.9668 -60.6517 29.92 -18.39 -21.3538\nIC4888 296.2176 -54.4567 29.82 -18.29 -21.2615",
