Abstract
We report the discovery of a pair of Seyfert galaxies identified in the ROSAT bright source, 1RXS J000306.3-041932. The two Seyferts have the same redshift of 0.106. The angular distance between them is ${\sim}23\arcsec$, corresponding to a projected separation of ${\sim}73$ kpc, and suggesting an interacting system. We argue, from its weak IR emission and relatively large nuclear separation, that the system is an example of the interaction between AGNs, rather than interaction-triggered AGN activity.
