Scientific paper

Results are presented for spectral observations of 94 Markarian galaxies over the wavelength range from 5900 to 7700 A with a resolution of 5 to 8 A. Radial velocities are measured, and residual line intensities estimated, for 64 galaxies in which emission lines are observed. Ten of these galaxies are found to have no emission lines in the red region of their spectra, six are found to exhibit probable Seyfert characteristics, and broad emission lines are observed or suspected in eight objects. Hydrogen emission lines are detected in Markarian 396, and this object is identified as a white dwarf (probably of type DA). Markarian 586 is identified as a probable quasar. The mean error in radial velocities is estimated to be 60 to 70 km/s.
