Precise determination of the superhump period and its period change is very important. If you still have time, would it be possible to try QW Ser (vsnet-alert 5068 and vsnet-campaign 302) in the evening? Probably your good coverage of V1504 Cyg would enable to allocate a shorter nightly time for V1504 Cyg (enough for timing superhumps) and longer time for QW Ser. Regards, Taichi Kato
