In the Hubble Space Telescope /Cosmic Origins Spectrograph spectrum of the Seyfert 1 galaxy 2MASX J14292507+4518318, we have identified a narrow absorption line outflow system with a velocity of −151 km s−1. This outflow exhibits absorption troughs from the resonance states of ions like C  iv , N  v , S  iv , and Si  ii , as well as excited states from C  ii * and Si  ii *. Our investigation of the outflow involved measuring ionic column densities and conducting photoionization analysis. These allow the total column density of the outflow to be estimated as log  N H = 19.84 cm−2, its ionization parameter to be log  U H = −2.0, and its electron number density to be log  n e = 2.75 cm−3. These measurements enabled us to determine the mass-loss rate and the kinetic luminosity of the outflow system to be |$\dot{M}$|  = 0.22  |$\mathrm{ M}_{\odot } \, \mathrm{ yr}^{-1}$| and |$\log \dot{E_{\mathrm{ K}}}$|  = 39.3 erg s−1, respectively. We have also measured the location of the outflow system to be at ∼275 pc from the central source. This outflow does not contribute to the active galactic nucleus (AGN) feedback processes due to the low ratio of the outflow's kinetic luminosity to the AGN's Eddington luminosity (⁠|$\dot{E_{\mathrm{ K}}}/{L_{\mathrm{ Edd}}}\approx 0.00025 {{\, \rm per\, cent}}$|⁠). This outflow is remarkably similar to the two bipolar lobe outflows observed in the Milky Way by XMM–Newton and Chandra. [ABSTRACT FROM AUTHOR]
