It was found that the 13CO line-emitting regions with blue- and redshifts are clearly separated on north-west and south-east sides of the curved axis in the ρ Oph streamer (north), respectively (Uchida et al. 1989a). A most likely interpretation is that the streamer is spinning around its curved axis. We discuss here the implication of this in connection to the evolution of the massive cloud of active star formation located at the south-west end of it by introducing a magnetodynamic picture which is related to the sweeping-magnetic-twist mechanism proposed by Uchida and Shibata (1985) for the production of molecular bipolar flows from forming stars.
