Аннотация: We present UBVRI monitoring of the new dwarf nova objectduring its main outburst in June 2017, apost-super-outburst phase, series of rebrightenings and a quiescencestage. We found the period of superhumps (P_{sh}) close to 0.063 days.The period variations are analyzed by the (O-C) method during differentstages of outburst activity.We constructed and interpreted the multicolor and color indices lightcurves as well as the tracks of the object in various two-color diagrams. We estimated changes of the color temperature during the outburst and brightness decline, the luminosity, the value of dP/dT, the superhumps excess (P_{sh}/P_{orb} - 1), the mass ratio, the distance to the system and other physical parameters.The time intervals between rebrightenings of our object are compared with other similar objects. After the series of rebrightenings our object returned to a quiescence stage.
