ASASSN-19ado: ordinary superhumps

I have been observing ASASSN-19ado every clear night since the detection of
its outburst. My most recent observation set (2020, Jan 10/11) shows that
this object finally (!) has started to show ordinary superhumps with an
amplitude of 0.20 mag. Using the ANOVA, Lomb-Scargle and PDM period
determination methods of Peranso, I find a superhump period of 0.0690 +/-
0.0012d.

All of my observations will soon be posted to the AAVSO database.

Best regards
Tonny
