ASASSN-26fa: new SU UMa-type dwarf nova, possibly WZ Sge-type ASASSN reported the discovery of ASASSN-26fa at 14.63 mag on 2026-08-31.18 UT. According to vsx, this object's quiescence mag is at g=~23 https://vsx.aavso.org/index.php?view=detail.top&oid=10876034 Sjoerd Dufoer and Moriyama-san reported time-resolved observation. The light curve shows clear ordinary superhumps with a period of 0.0636(8) d and an amplitude of 0.3 mag. Thus ASASSN-26fa is a new SU UMa-type dwarf nova. Given its short superhump period and large outburst amplitude, this is a good candidate for a WZ Sge-type dwarf nova. Follow-up observations are encouraged. Best regards, Hiromasa Hoke
