Multiband photometry of CY Aquarii: the 2011 season
Abstract
Based on more than a dozen partial nights of filterless CCD photometry combined with Strömgren uvby photomultiplier photometry, we derive 29 new times of maximum light of the SX Phoenicis star CY Aquarii. These times support a linear ephemeris for 2003-2011. In addition, we present uvby light curves for this star. Our dataset displays the smallest residual spread compared to any other substantial dataset published during the last decade.
