[vsnet-newvar 9099] ASASSN-22cw: most likely new WZ Sge-type dwarf nova
by Taichi Kato 10 Mar '22

10 Mar '22

ASASSN-22cw: most likely new WZ Sge-type dwarf nova Berto Monard has reported observations. Two cycles of variations were recorded. The period was 0.0528(7) d and a full amplitude of 0.08 mag. The profile is doubly humped with the second one brighter and this suggests that the variation early superhumps. Note that the period may be shorter than 0.05332 d in GW Lib. Further observations are needed to confirm and then update the period.
