Compton y-map (MILCA) and zoomed RGB SDSS image of the region around PSZ2 G069.35–15.58. The black contours correspond to the 3, 6, 9 × 10⁻⁶ levels of the Compton y-map in this area where the small red circle indicate the nominal Planck position from the PSZ2 catalogue. In the RGB image, the white contour corresponds to the 9 × 10⁻⁶ level and the PSZ2 coordinates. The BCG of this system is clearly placed at less than 1′ to the south-west from the nominal Planck pointing. Potential cluster members are consistent with a z_phot ∼ 0.09 and occupy the area of ∼12′ × 12′.
