[vsnet-newvar 8826] ZTF18abncpgs: strange object, ER UMa-like and standstill
by Taichi Kato 23 Sep '21

23 Sep '21

ZTF18abncpgs: strange object, ER UMa-like and standstill From ZTF data. Superoutburst-like bright state in 2019 Jul.-Aug., followed by a sequence of short outbursts. Then another superoutburst-like bright state in 2019 Oct.-Dec. followed by a sequence of short outbursts. The behavior resembles RZ LMi when supercycle lengthened. Apparent standstill in 2020 Nov.-2021. Shorter (super)cycle length in 2018. Suggesttion: UGER:+UGZ
