- Аннотация: The authors have investigated the kinematics of ionized gas in the center of Seyfert 2 galaxy NGC 5929 at the 6-m telescope. Two gas clouds being the main forbidden line emitters in the center of NGC 5929 are found to possess the relative line-of-sight velocities -50 km/s (the eastern cloud) and +270 km/s (the western cloud); these values exceed the maximum projection of the galaxy rotation velocity on the line of sight (30 km/s). The clouds are rather extended: the eastern cloud is aligned at the position angle 80 - 85° by 0.7 kpc, the western cloud - at the position angle 130° by 3 kpc; the western cloud shows the own rotation. The emission brightness centers which coincide with the radio lobes are probably the shock wave regions forming on the border between the clouds and the galactic disk.
