Dear Colleagues,

After my second night of coverage, I looked for Psh on the whole data 
available, finding a Psh candidate of Psh=1.431(0.005) hours.

Superhumps increased in amplitude, now being 0.2 mag large.

I've just realized that in 2009 superhumps were already seen on this 
star by Nakajima-san and Maehara-san (although their coverage was too 
short for a fiurm estimate of Psh).

Data will be sent to Kyoto for analysis.
