The spatial distribution of galaxies in the Leo II B filament (blue circles). Gray circles represent galaxies in the Leo Minor and Leo II A filaments. MCG+08-16-005 is marked with an open red circle, UGC 04393, the nearest galaxy to MCG+08-16-005, is shown with an open cyan circle. Inset (a) displays a grz-composite color image of DECaLS for MCG+08-16-005. Inset (b) shows an r-band contour image of MCG+08-16-005, using a logarithmic flux scale normalized by the peak flux. The blue hexagon in (a) marks the field of view of MaNGA, and the orange line in (b) indicates a contour with a semimajor axis of ∼12″. A scale bar representing 5″ is shown in the bottom left corner of the insets. Inset (c) is a wide-field gri SDSS image including both MCG+08-16-005 and UGC 04393. In all insets, north is up and east is to the left.
