The X-ray emission in the {\\it ROSAT} band is dominated by thermal emission from the hot intracluster medium of the associated cluster. Image deprojection confirms the existence of a significant cluster cooling flow with total mass deposition rate of $\\sim 250\\,{\\rm M}_\\odot\\,{\\rm yr}^{-1}$ and a (Hubble time) cooling radius of $\\sim 180$\\,kpc.
