Photoelectric Photometry at the Hvar Observatory. III. The AP Star CQ UMa
Abstract
The UBV observations of the Ap star CQ UMa, obtained at the Hvar Observatory in 1973 and 1975, are combined with all other available photometric data to get an improved value of the period P = (2.449967 + or - 0.000025) days. The Hvar photometry also enabled the absolute UBV values for CQ UMa to be derived and the position of the variable in the color diagram to be discussed.
