[vsnet-newvar 9941] ASASSN-13bs: not (yet) SU UMa star?
by Taichi Kato 30 Mar '23

ASASSN-13bs: not (yet) SU UMa star? On two occasions (2018 Aug. and 2021 Apr.) when T. Vanmunster reported superhumps, the corresponding outbursts have been confirmed to be short (ATLAS/ZTF). They were unlikely true superoutbursts. I changed UGSU to UG. No long outbursts have been recorded in these data.

ASASSN-VJ065237.19+243622.3: IW And star, similar to BO Cet? ATLAS+ASAS-SNL+ATLAS data. IW And state in 2016-2019. In 2021 Oct. - 2022 Apr., standstill - brightening - fading - cycles of outbursts - long, bright outburst in 2022 Apr. similar to BO Cet. Although the data were not sufficient, this outburst may have been a superoutburst. The object is bright (15-16 mag) and observations are encouraged.
