Abstract
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 g(eff)=4.04 and effective temperature of 7740 K are found from mod el-atmosphere grids. The star is metal poor with a derived [Fe/H]=-1.5 . A mass of 1.06 M(.) is found from the analysis, the radius is 1.59 R (.), and absolute visual magnitude is M(V)=2.5.
