We present the discovery of an isolated compact group of galaxies that is extremely dense (median projected galaxy separation: 6.9 kpc), that has a very low velocity dispersion (σ 2 D = 67 km s -1 ), and in which all observed members show emission lines and are morphologically disturbed. These properties, together with the lack of spiral galaxies and the presence of a prominent tidal tail, make this group one of the most evolved compact groups.
