继续Kato等人（2009，PASJ，61，S395）描述的项目，我们收集了主要在2017年季节观察到的102个SU UMa型矮新星的超级峰最大值的时间，并对这些物体进行了表征。WZ Sge型恒星包括PT And、ASASSN-17 ei、ASASSN-17 el、ASASSN-17 es、ASASSN-17 fn、ASASSN-17 fz、ASASSN-17 hw、ASASSN-17 kd、ASASSN-17 la、PNV J20205397$+$2508145和TCP J 00332502 $-$3518565。我们获得了新的质量比7个对象使用不断增长的超级驼峰（阶段A）。ASASSN-17 gf是一个低于周期最小值的EI PSC型天体。CRTS J080941.3$+$171528和DDE 51是周期间隙中的对象，并且都显示了A阶段超级驼峰的长期持续阶段。最后总结了近年来对SU UMa型和WZ Sge型矮新星的研究进展。
Continuing the project described by Kato et al. (2009, PASJ, 61, S395), we collected times of superhump maxima for 102 SU UMa-type dwarf novae observed mainly during the 2017 season, and characterized these objects. WZ Sge-type stars identified in this study are PT And, ASASSN-17ei, ASASSN-17el, ASASSN-17es, ASASSN-17fn, ASASSN-17fz, ASASSN-17hw, ASASSN-17kd, ASASSN-17la, PNV J20205397$+$2508145, and TCP J00332502$-$3518565. We obtained new mass ratios for seven objects using growing superhumps (stage A). ASASSN-17gf is an EI Psc-type object below the period minimum. CRTS J080941.3$+$171528 and DDE 51 are objects in the period gap, and both showed a long-lasting phase of stage A superhumps. We also summarize the recent advances in understanding of SU UMa-type and WZ Sge-type dwarf novae.
