Аннотация:The results of photometric observations of cataclysmikc variable ASAS-SN-13cx are presented. CCD observations were taken in August-September 2014 (outburst) and in October-November 2016 (quiescence) using the 50-cm and 60-cm telescopes, more than 1800 images in V and Rc filters. Detailed light curves for the system active and quiescent states are plotted. A "spiral" model is applied to solve for the parameters of ASAS-SN-13cx during the outburst which takes into account the geometric disturbances on the accretion disk surface. We searched for the parameters in quiescence with a "composite" CVs model taking into account an accretion disk with hot spot on the lateral surface geometrically thick outer edge of the disk. The basic parameters of ASAS-SN-13cx are found for the first time including q=M1/M2=7.0+/-0.2, i=79.9-80.1, ao=0.821(1)Ro, radiuses R1=0.0102(4)Ro, R2+0.194(3)Ro and temperatures of the components T1=12500+/-280 K, T2+2550+/-400 K. These parameters correspond to M4-9V spectrum of the secondary. The mass of the accretion disk approximately doubles during quiescence on a time scale of about 400 orbital periods. The classification of ASAS-SN-13cx as a SU UMa dwarf nova is confirmed.
