- Аннотация: We carried out interferometric H alpha observations of the extended IR shell around NGC 6888 and WR 136 in the northwestern part of the gas and dust complex associated with Cyg OB1 and Cyg OB3. High-velocity motions were detected in a small region at the boundary of the IR shell, which we associate with the spherically symmetric shell nebula Simeiz 55. The processing of archival IUE data also revealed interstellar absorption lines in the spectrum of the star HD 228519 (B0.5 V), lying at the center of Simeiz 55, at least in the plane of the sky, at the largest negative velocities encountered in the shell complex. The radial-velocity field in the nebula can be interpreted as an asymmetric expansion of the shell with a velocity of 75 km s(-1). The possibility that the nebula is an unrecognized supernova remnant in the radiative phase is not ruled out.
