CY Aqr multiband photometry: 2011 season

Based on more than a dozen partial nights of filterless CCD photometry combined with Stromgren uvby photomultiplier photometry, we derive 29 new times of maximum light of the SX...本研究基于十余次无滤光片CCD（charge-coupled device）测光的部分夜间观测，结合斯特龙根（Stromgren）uvby光电倍增管测光数据，推导出SX天体共29个新的光变极大时刻。
