V503 Cyg superhumps: Jochen Pietz Dear Colleagues, We have received a report from Jochen Pietz that a CCD time-series photometry on July 28 shows a sequence of 0.1 mag humps and substructures. The object has been followed by the Kyoto team since the start of this superoutburst. More detailed analysis will be undertaken by Ishioka-san. Regards, Taichi Kato VSNET Collaboration team
