[vsnet-outburst 31595] ASASSN-25en: new SU UMa-type dwarf nova
by Yusuke Tampo 02 Dec '25

02 Dec '25

ASASSN-25en: new SU UMa-type dwarf nova ASASSN discovered ASASSN-25en on 2025-11-03 UT at 14.94 mag. The outburst amplitude in the VSX is ~7.5 mag. https://vsx.aavso.org/index.php?view=detail.top&oid=10868163 Josch Hambsch and Itoh-san have reported the time-resolved observations. The light curve after 2025-11-11 UT shows a single-peaked superhump with a period of either 0.06003(3) or 0.06390(3) d. Thus, ASASSN-25en is a new SU UMa-type dwarf nova. The rapid decline from the outburst was observed around 2025-11-21 UT.
