Caption: Figure 5.

Left: quasi-simultaneous (within 1 hr) ﹩\nu -{F}_{\nu }﹩ plotted measurements of V404 Cyg observed by Kanata/HONIR and Swift/XRT on MJD 57193. The simultaneous Ks- and R-band fluxes measured during the orphan Ks-band flare are shown with magenta stars. Right: same as the left panel, but for the Kanata/HONIR and Swift/XRT data taken on MJD 57194. Also shown in both panels are preliminary nonsimultaneous 2.4–21.7 GHz RATAN-600 fluxes from Trushkin et al. (2015a). For illustrative purposes only, dashed lines indicating various spectral indices (﹩\alpha =0﹩ and −1.0 in both, plus additional ﹩\alpha =0.2﹩ in left panel; ﹩{F}_{\nu }\propto {\nu }^{\alpha }﹩) are shown.
