Аннотация:In this work, an analysis of the optical variability of the intermediate polar SDSS J201116.8+600428 is presented. We have carried out simultaneous optical and infrared observations of the object in V, i, z and K passbands and obtained the light curves that show notable similarities, but each curve exhibits variability, which is weakly repetitive from one orbital cycle to another. The spectroscopic data confirm that the object belongs to the class of cataclysmic variables and includes a magnetic white dwarf. The radial velocities of the hydrogen and helium emission lines do not indicate the orbital motion in the system.
