Abstract

We report new spectroscopic data on the symbiotic system FN Sagittarii, secured by using flux-calibrated spectra in the region of H-alpha and H-beta. The behavior of the continuum and the emission-line parameters, such as radial velocities, fluxes, and equivalent widths, are discussed. The spectral classification of the cool component is obtained by means of the TiO optical molecular-band strengths.
