Dear colleagues,

 We have received time-resolved data of SDSS J081207.63+131824.4 from
Nakajima-san. I also succeeded in observing the object last night.
The data show clear superhumps with an amplitude of 0.3 mag suggesting 
that the object is an SU UMa-type dwarf nova.
The superhump period is around 0.08d.

Follow-up observations are strongly encouraged.
