ASASSN-20pl (= TCP J03360414+4924332) : emergence of ordinary superhumps
(already in Stage-B?)

We, Kyoto Univ. team observed ASASSN-20pl on December 17th, and detected
single-peaked ordinary superhumps.
We obtained its period as 0.0616(1) d and its amplitude as > 0.15 mag.
Even though no time-resolved data were reported in the recent 3 days, as
the superhump amplitude is large and profile is very clear, ASASSN-20pl
might already in Stage B of superoutburst stage.

Time-resolved photometry is encouraged.

Best,
Yusuke
