(Kyoto U)\n\nIn response to the IceCube-190503A alert (GCN Circular No. 24378), HONIR --\nthe optical-NIR muti-band simultaneous multi-capable instrument -- on the\n1.5m Kanata telescope observed possible Blazar candidates. The candidates\nwere selected from our sample prepared for finding an IceCube counterpart.\nNone of them were flared up within two days observations. We also checked\nour images with archival PanSTARRS images, and didn't find any transient.\n\nra,         dec,      5/4 R J   Ks,   5/5 R J   Ks\n119.797654, 6.627546, 19.6 18.8 ----, 19.4 19.0 ----\n120.038609, 6.164517, 20.3 19.4 17.4, 19.3 19.3 17.0\n120.222161, 6.857248, 16.0 ---- ----, 17.7 17.9 ----\n120.267315, 6.441576, 19.1 18.6 ----, 18.6 18.6 ----\n120.318049, 6.476643, 17.3 15.8 ----, 17.6 18.0 ----\n120.375726, 6.197231, 19.8 19.2 17.5, 19.8 19.3 13.0\n\nAll limiting magnitudes with 5 sigma in AB unit are calibrated with\nPanSTARRS and 2MASS point sources.\n\nThis result is consistent with GCN Circular No. 24409.
