We have imaged the H2O maser and 22, 8, & 5 GHz continuum in the nucleus of NGC 3079, using the NRAO VLBA. The maser features are distributed over ~ 2 pc along an axis aligned with the plane of the kpc–scale edge–on molecular disk. The masers are not angularly coincident with any detected continuum emission. The two brightest continuum features, which trace a parsec–scale jet, have similar spectra that peak at frequencies ν > 5 GHz. We also detected faint maser emission along the jet axis.
