[vsnet-campaign-dn 15980] ASASSN-21rm: new likely WZ Sge-type dwarf nova
by Taichi Kato 13 Sep '21

13 Sep '21

ASASSN-21rm: new likely WZ Sge-type dwarf nova Tamas Tordai has reported observations. The object showed humps on Sep. 11. The period was 0.0548(6) d and the amplitude was 0.14 mag. The profile resembles that of early superhumps. Combined with the large outburst amplitude, this object is likely a WZ Sge star.
