Results of spectroscopic observations of the nucleus of the S component of the galaxy Kaz 163, carried out on the 6-m telescope of the Special Astronomical Observatory in 1982, are presented. The equivalent widths, relative intensities, and half-widths of emission lines were determined. The electron temperature, electron density, and mass of the gaseous component of the nucleus were also determined. The half-widths and equivalent widths varied almost twofold over the time of observations from October 31, 1981, to May 28, 1982. During the same time the intensity of the [O III] λ4363 auroral line increased fairly strongly.
