Аннотация:We present our variability study of the new cataclysmic variable star, 2MASS 23212116+3807563. The variable is a U Geminorum type star. An analysis of available electronic archives data (CSS, 1SWASP and ASAS-SN) does not detect periodicity. The variable has a close companion, photometric data in the electronic archives present combined light of the two stars. We acquired the star's new CCD photometry in Johnson's B, V, and R bands. Our observation confirm variability of 2MASS 23212116+3807563 with a large amplitude of light variations (more than 3m).
