ASASSN-17qf: early? superhump weaken

Crimean Astrophys. Obs. team, Kiyota-san, Itoh-san and Kyoto U. team
has reported further obsrvations.
     The object is 15.5 mag and the outburst has continued for 2 weeks.
We were able to see very weak double-wave modultaions like the early superump
whose amplitude is about 0.01 mag, but now the signal of (early?) superhump
weaken and it has become difficult to detect it. Basically, the ordinary superhumps
are grown after the amplitude of early superhumps decrease. Thus it is expected
that ordinary superhumps will be grown in near future.
     Further obsrvations are encouraged.
