[vsnet-alert 14644] Re: possible new CV

[Seiichi Yoshida]

Dear Denis Denisenko,

Thank you very much for your report. I am very glad that the outburst
of this star was confirmed :-)

We the MISAO Project assign the new variable star number "MisV1448" to
this star.

Well, maybe it is already too late, but I forward your report to
Dr. Dan Green, CBAT.

Best regards,
