ASASSN-20ny: likely new SU UMa-type dwarf nova

Kyoto Univ. Obs. observed ASASSN-20ny on 12th Nov. for ~ 2hrs.
We detected a possible superhump with an amplitude of ~0.2 mag, however,
the baseline was too short to determine a variation period.
This object is currently around 17 mag based on ZTF Lasair data.

Judging from its light curve profile and large outburst amplitude of ~6mag,
ASASSN-20ny is likely a SU UMa-type dwarf nova.
