We obtained a = 8.5 hrs unfiltered CCD photometry run on BC UMa, using the 0.35-m f/6.3 = robotic telescope. The corresponding light curve shows very prominent = superhumps, with an average amplitude of 0.33 mag. A first period = analysis using the PDM method reveals a superhump period of 0.0642 d, = which is above earlier published superhump period values. Best regards, Tonny Vanmunster CBA Belgium Observatory
