HS2331+3905: early superhump disappeared!
Our observation last night (11 Sep.) shows a dramatic
decrease of the amplitude of early superhumps.

As can be seen in the above page, the light curve on 11 Sep.
only has modulations with amplitudes of ~0.1 mag.
They are significantly smaller than those observed on 10 Sep.
It is probably a sign of the growth of normal superhumps.
The evolution of superhumps may be observed in the next
couple of days.
