Dear Colleagues,

last night, I did 2.5 hours of time resolved photometry on this star,
remotely using the 14" unit part of the Virtual Telescope Project.

The star was clearly showing superhumps, so - as I mentioned earlier - 
this is a new SU UMa star.

Superhumps have a full amplitude of 0.1 mags.

A search for Psh, using all the available data, provided a candidate of 
1.48 hours.

Data will be sent to Kyoto for analysis.

Regards,
Gianluca Masi
