Photometry of CY Aqr in the uvby-Beta and V(RI)C photometric systems has been secured and analyzed. A phase-averaged effective gravity of log geff = 4.04 and effective temperature of 7740 K are found from model-atmosphere grids. The star is metal poor with a derived [Fe/H] = -1.5. A mass of 1.06 solar mass is found from the analysis, the radius is 1.59 R and absolute visual magnitude is M_V = 2.5m. (SECTION: Stars)
