Аннотация: Context. Jets and disk winds play an important role in the evolution of protoplanetary disks and the formation of planetary systems. However, there is still a lack of observational data regarding the presence and parameters of outflows, especially for close young binaries.Aims. In this study, we aim to find the HH flow near the young sub-arcsecond binary DF Tau and explore its morphology.Methods. We performed narrow-band Hα and H2 2.12 μm imaging and spectroscopic observations of DF Tau and its vicinity.Results. We discovered several emission nebulae near the binary, which likely result from the interaction of gas outflow from the binary components with the surrounding medium. The outflow appears to occur both in the form of jets, generating numerous Herbig-Haro objects (HH 1266 flow), and as a weakly collimated wind responsible for the formation of the ring-like nebula around the binary and the rim of the cometary globule. We find that the angle between the jet and the counter-jet is 168° and provide a discussion on the complex morphology of the HH flow.
