ASASSN-20nk : new SU UMa-type dwarf nova

Josch Hambsch and Berto Monard reported observations of ASASSN-20nk since
27th Oct.

Observations on 30th and 31st detected superhumps with a period
of 0.0612(1) d. and amplitude of ~0.2 mag, establishing ASASSN-20nk is a SU
UMa-type dwarf nova.

Based on its large outburst amplitude (no ViziR match) and short superhump
period, ASASSN-20nk is a good candidate for WZ Sge-type dwarf nova.

Continuous time-resolved observations are encouraged.

Best,
Yusuke
