1E 0116.3-0116 is an extended X-ray source with a luminosity (0.3 - 3.5 keV) of 1.1×1043ergs s-1. The identification of this MSS source with an E3 galaxy belonging to a sparse group of galaxies makes this object quite peculiar. The X-ray emitting gas has a radius of ≡4arcmin and a temperature greater than 2 keV. The optical spectrum of the galaxy shows no signs of nuclear activity. If the gas is isothermal, its surface brightness profile yields a total mass greater than 1013M_sun;. In optical and X-ray luminosity and mass-to-light ratio, this galaxy most resembles M87.
