Photometric studies of the SU UMa-type dwarf nova IRXS J161659.5+620014 have been made on the 2.6-m and 1.25-m telescopes at the Crimean Astrophysical Observatory during 2017 and 2018 in the quiescent state of the system, during normal outbursts, and during superoutbursts. It is found that the interval between adjacent normal outbursts was about 11 days during 2017. Observations in the quiescent state during 2017 yielded an orbital period of 0.06888(2) days. Observations during 2018 manifested good reproducibility of the characteristics of the superoutbursts compared to those of previous years. A refined period of 0.071044(15) days was obtained for the positive superhumps in stage “C” and their color indices were determined.

SU UMa型矮新星IRXS J161659.5 + 620014的光度研究于2017年和2018年在克里米亚天体观测站的2.6 m和1.25 m望远镜上处于系统静止状态，正常爆发期间进行，在爆发期间 已发现，2017年相邻两次正常爆发之间的间隔大约为11天。2017年处于静止状态时，观测到的轨道周期为0.06888（2）天。与往年相比，2018年的观察结果表明超级爆发特征具有良好的可重复性。对于阶段“ C”中的正超级峰，获得了0.071044（15）天的精炼时间，并确定了它们的颜色指数。
