Abstract
. RS Oph is a recurrent symbiotic novae which underwent its last optical eruption in August 2021. The early H α 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.
