Continuing the project described by Kato et al. (2009, PASJ, 61, S395, arXiv/0905.1757), we collected times of superhump maxima for 102 SU UMa-type dwarf novae observed mainly during 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 TCP J00332502-3518565. We obtained new mass ratios 7 objects using growing superhumps (stage A). ASASSN-17gf is an EI Psc-type object below period minimum. CRTS J080941.3+171528 DDE 51 gap both showed long-lasting phase stage A superhumps. also summarized recent advances understanding novae.
