Abstract: We present preliminary results of BVRcIc photometric observations of 1SWASP J162117.36+441254.2 during the 2016 outburst. Observations were carried out at 1.25-m telescope located in Crimean Astrophysical Observatory. Previously this star was thought as eclipsing variable of the W UMa-type until the outburst, but with the help of numerous worldwide observations this object was classified as the long-term dwarf nova. Our findings demonstrate the dramatic changes of the light curves profile in all color bands during the outburst. This can be interpreted as the presence of erupted accretion disk at the early stages of outburst and the emergence of ellipsoid effect of the secondary component of the system at a later stage.
