Superhumps in CY UMa confirmed Dear Colleagues, A time-series CCD photometry on Feb. 12 (Ouda team rooftop station, 25-cm SCT + ST-7 unfiltered) has revealed the presence of large-amplitude superhumps (amplitude = 0.33 mag) in CY UMa. The persent observations confirmed the superoutburst nature. There is an indication of superimposed QPOs (amplitude ~ 0.10 mag) during the decline branch from superhump maxima. Regards, Taichi Kato
