Abstract: RS Oph is a recurrent symbiotic novae which underwent its last optical eruption in August 2021. The early Hα spectroscopy of the system (at days 11--15 of the outburst) reveals satellite line components at the velocity position of about ±2400 km s^-1 which are an indication of bipolar collimated outflow. We derived some parameters of the outflows and system's components and their evolution during our observation.
