[vsnet-alert 13449] OT J231308.1+233702 = TCP J23130812+2337018 = Itagaki transient

[Gianluca Masi]

Dear Colleagues,

I managed to cover this new SU UMa star again for about 2.5 hours, 
before sunrise.

Using my three consecutive nights data, data, a search for Psh provided 
a candidate of 1.709(0.002) hours. Using the first two nights, I get a 
Psh estimate of 1.7143(0.005)h, while the last two night5s provide an 
estimate of 1.7070(0.005)h. So, a period decrease was observed.

The whole lightcurve is here:

Data are going to be sent to Kyoto for analysis.
