- Аннотация: Monochromatic [OIII] and [NII] observations and interferometric H(alpha) observations of the HII nebula, connected with stars WR 134 and WR 135, have been carried out. The radial velocity field of this nebula was investigated. Basing on nebula morphology and kinematics, we supposed that the closed elliptical emission shell, including the nebula Anon MR 100, was formed by WR 134 stellar wind action. The investigated shell is a part of the hierarchical shell system in the region of the associations Cyg OB1 and OB3, at least, in the sky plane. It is shown that the star WR 134 has blown a shell al the edge of the parent molecular cloud, emitting at the velocity 5-7 km/s. Because of the inhomogeneous density distribution in the surrounding medium, the shell's expansion was not the same in the different directions: inside the cloud at a velocity close to 20 km/s, and outward in the northern direction at a velocity about 50 km/s.
