Multiwavelength views of the bright UV region at r_gal = 1.36 r₂₅, showing from left to right the NUV, 24 μm, and H I 21 cm emission in flux units of 10^-9 MJy sr^-1, MJy sr^-1, and K km s^-1, respectively, as indicated by the color bars. The circles of 22″ diameter refer to the positions of the 12 pointings used to map the CO(1–0) emission. The Hα emission is undetected in this external region of the M 63 galaxy.
