Subject: [vsnet-alert 20778] OV Boo outburst

Dear colleagues,

I am Seiichi Yoshida working on the MISAO Project.

Masaru Mukai, Kagoshima, Japan, reported that OV Boo (R.A. 15 07 22.35, Decl. +52 30 39.8) is bright as 11.4 mag on Mar. 14.63 (UT), using Nikon 105-mm lens + CCD (STL6303E) + IR-cut filter.

The VSX data shows it is a CV+EA+ZZ/GWLIB type with a range of 18.0-20.6 mag.

Best regards,
