 ASASSN-20cd: New WZ Sge-type dwarf nova

Berto Monard has reported the 3-night observations of ASASSN-20cd.
The folded light curve includes a possible eclipse and a period
of 0.05438(2) d has been suggested.
This short orbital (or early superhump) period suggests that ASASSN-20ct is
a WZ Sge-type dwarf nova.

More observations are encouraged!
