     OV Boo has ultra-short period of 0.046 d, and the period is below the period minimum.
By the spectroscopic study, Patterson et al. (2008) suggested that OV Boo is a member
of WZ Sge stars, but the object had shown no outbursts.
     This outburst is very likely to be a WZ Sge-like superoutburst. Thus time-series
observations are strongly encouraged.
