[vsnet-alert 12802] Re: OT J120052.9-152620 = Catalina transient

[Gianluca Masi - VT]

Dear Colleagues,

I'm observing this star right now, remotely using the
photometric unit of the Virtual Telescope Project: it is
still bright at mag 14.3 right now.

After one hour of coverage, I see a curve inclucing a
minimum, with a possible full amplitube of 0.2 mags.

So, very likely, this is a SU UMa class CV.

Regards,
Gianluca
