本文介绍了2014年和2016年对矮新星NY Ser的观测结果。2014年共获得126个夜晚的数据，其中包括20次正常爆发和1次超级爆发；2016年共获得22个夜晚的数据，其中包括5次正常爆发。正常爆发曲线的形状表明该系统存在“由外向内”和“由内向外”的爆发。在突出活动的不同阶段（静止状态、突出和超突出），NY Ser表现出不同周期的亮度振荡。在静止状态和正常爆发时，轨道周期为0d。097558(6)成为主流。在超级爆发期间，我们确定了超级峰演化的两个阶段：吸积盘潮汐不稳定性增加的阶段(a)和超级峰发育的阶段(B)。第一次确定了NY Ser的A阶段，但其持续时间和周期并不唯一确定。B期为阳性超峰，平均周期为0d。10464(9)，周期超过ε = 0.072，平均周期为0d的负超峰。0938(1)和ε = -0.038的周期亏缺首次被检测到。
Results from observation campaigns for the dwarf nova NY Ser during 2014 and 2016 are presented. Data were obtained on a total of 126 nights in 2014 that include 20 normal outbursts and one superoutburst and on 22 nights in 2016 that include 5 normal outbursts. The shape of the curves for the normal outbursts indicated the existence of “outside-in” and “inside-out” outbursts in this system. In different stages of outburst activity (quiescent state, outburst, and superoutburst) NY Ser manifests brightness oscillations with different periods. In the quiescent state and in normal outbursts, the orbital period 0d.097558(6) predominated. During the superoutburst we identified two stages in the evolution of superhumps: a stage in which the tidal instability of the accretion disk increases (A) and a stage with developed superhumps (B). Stage A for NY Ser has been identified for the first time, but its duration and period are not uniquely determined. In stage B, positive superhumps with an average period of 0d.10464(9) and a period excess of ε = 0.072 were recorded and negative superhumps with an average period of 0d.0938(1) and a period deficit of ε = -0.038 were detected for the first time.
