The radio source is GigaHertz Peaked Spectrum and compact (0.13 kpc), implying an early stage of evolution ($\\leq 10^4$ yr). Our data show an interacting pair of galaxies, projected separation 9.1 kpc, velocity difference $\\Delta(v)=216$ km $\\rm s^{-1}$. The larger galaxy is a $\\rm M_{*}\\simeq 10^{11}M_{\\odot}$ spheroidal with the emission-line spectrum of a high-excitation young radio AGN, e.g. strong [OI]6300 and [OIII]5007.
