ASASSN-26dv: new SU UMa-type dwarf nova and a candidate period bouncer ASASSN-26dv was discovered by ASASSN on 2026-06-23.03 UT at 14.62 mag. After the initial decline, ATLAS and ASASSN light curves showed a short dip around 2026-07-05 UT. https://vsx.aavso.org/index.php?view=detail.top&oid=10875895 The time-resolved observations after this dip by Berto Monard show likely positive superhumps, with a period of ~0.055 d. Thus, ASASSN-26dv is a new SU UMa-type dwarf nova with a possible dip in the outburst plateau, which is often seen in outbursts in period bouncers. Further time-resolved observations are encouraged to establish its superhump period.
