Abstract
HI observations with the RATAN-600 radio telescope have confirmed the presence of a ring structure of neutral hydrogen in the region of Cyg OB 1, at least at positive velocities, and revealed no traces of radia l gas motions in this association. In the region of the radio source C ygnus X and the Cyg OB2 association, the HI distribution has been foun d to be related to the huge shell previously detected by H-alpha filam ents and to the distribution of ionized gas as derived from recombinat ion lines.
