Some recent studies have detected a compact radio-emitting nucleus in this object, coinciding with the photometric center and with a candidate for the X-ray nucleus. This is evidence of the existence of a low-luminosity active galactic nucleus (AGN) in the galaxy, although no emission line has ever been observed. We report the detection of an emission-line spectrum of a type 1 AGN in NGC 3115, with an H$\\alpha$ luminosity of $L_{H\\alpha} = (4.2 \\pm 0.4) \\times 10^{37}$ erg s$^{-1}$.
