Scientific paper

Observations of galaxies along the galactic plane at 21 cm are discussed. Two observations per channel on a 100 m telescope equipped with a spectrometer and an autocorrelation spectrometer were performed. H I emissions were recorded in 10 instances and flux densities, signal-to-noise ratios, heliocentric radial velocities, and error estimates are provided. Measurements of another 10 possible galaxies with characteristics of H I emissions are given, including radial velocities and line widths. None of the observed galaxies appeared to be members of local group A. The linewidths of the detected galaxies were found to lie in the range for spiral galaxies.
