Abstract: Water-vapor maser emission of NGC 3079 has been observed with the VLBA by two groups to date. They proposed a compact masing disk in its nuclear region, but their interpretations of the disk were very different from each other. To clarify which model is correct, we performed a VLBA observation of blue- to red-shifted maser features. As a result, maser positions of some red-shifted features were newly determined and most features were distributed along a line near the north-south direction. We propose a nearly edge-on disk whose position angle is roughly −7°.
