Abstract
We present photometric and spectral observations of the symbiotic star ZZ CMi. We detect intranight variability—flickering and smooth variations in U band. The amplitude of the flickering is about (Formula presented.) mag in U band. In the B band, the variability is lower, with amplitude (Formula presented.) mag. We also detect variability in the (Formula presented.) and (Formula presented.) emission lines, and find an indication for outflow with velocity of about 120–150 km/s. The results indicate that ZZ CMi is an accretion-powered symbiotic containing an M4-M6 III cool component with a white dwarf resembling recurrent novae and jet-ejecting symbiotic stars.
