BZ UMa: Vanmunster's obsevation Dear Colleagues, Tonny Vanmunster has kindly sent the BZ UMa data (vsnet-campaign-dn 3160). We have confirmed Tonny's finding. The amplitude of variation related to orbital (or superhump) period is an order of 0.01 mag, assuming the reported period. Although the current outburst may be a normal outburst, QPO-like signals were most prominent during the declining stage in the past outbursts. Please keep this in mind and follow the evolution of the current outburst. Regards, Taichi Kato VSNET Collaboration team
