Optical image of the M 96 group in the background (SDSS color image) is shown in the left panel with H I contours of the Leo ring. In magenta, we show the Arecibo contour at N_HI = 2 × 10¹⁸ cm⁻², in yellow the VLA H I contours of the southern part of the ring as described by Schneider et al. (1986). Square symbols indicate the positions of the 3 H I clumps observed with MUSE: Clump1, Clump2, and Clump2E. Right panel: an enlargement of the 3 H I clumps shows the coverage of the 8.5 kpc² MUSE fields overlaid on the far UV-GALEX image.
