PU Per: superhump detection Dear Colleagues, From time-series CCD observations on Oct. 2 and 3 (K. Matsumoto, Ouda team rooftop station, 25cm-SCT + ST-7 unfiltered), we have been able to detect superhumps in PU Per. The best superhump period determined from two-night observations was 0.0723 d. This result confirms the claimed detection of superhump reported by Patterson et al. Regards, Taichi Kato and Ouda team
