UV Per likely superoutburst As reported by Mike Simonsen in [vsnet-outburst 1233], the SU UMa-type dwarf nova UV Per is undergoing one of its relatively rare outbursts! The most recent outbursts were in 1999 June (mv=12.8, Poyner, normal outburst) and 1998 July superoutburst. The outburst interval suggest that the present outburst is a superoutburst. Since the outburst looks young, we can expect to see the growth of superhumps (or even early superhumps) in this "semi-WZ Sge type" star. Time-resolved photometry is very strongly encouraged, especially at early epochs. See also [vsnet-future 17] for Watanabe-san's outburst prediction. Regards, Taichi Kato VSNET Collaboration team
