  We report the XMM-Newton discovery of a X-ray bright AGN pair in the
interacting galaxy system ESO509-IG066. Both galaxies host an X-ray luminous
(L_X ~10^{43} erg/s) obscured nucleus with column densities N_H~7x10^{22} and
N_H~5x10^{21} atoms/cm/cm. The optical morphology is only mildly disturbed,
suggesting a merging system in the early stage of its evolution. Still, the
pair is probably gravitationally bound, and might eventually evolve into a
compact, fully gas embedded systems such as NGC6240.
