SDSSJ115207.00+404947: likely stage A superhump

Maeda-san and Pavol A. Dubovsky reported new observations.
The object has shown superhumps and its amplitudes become larger.
So these superhumps seem to be stage A.
The superhump period is 0.0701(1) d, and the mass ratio is 0.084(6).
This mass ratio is rather small considering its orbital period.
More observations are encouraged.
