V660 Her outburst As reported by Christopher Jones, the (still poorly known) SU UMa-type dwarf nova V660 Her is likely undergoing an outburst. From the previous records, a superoutburst may be due now. Although the reported magnitude is still somewhat faint, the present likely outburst may evolve into a superoutburst. The object is very favorably situated, confirmation and further detailed observations are strongly encouraged. Regards, Taichi Kato on behalf of the VSNET Collaboration team
