摘要：

We carried out optical and Ha photometry of two contact binaries (V861 Herculis, EQ Tauri). The light curve modeling revealed stellar spots in both contact systems and strong Ha excess in the position of the observed stellar spots. A correlation was found between the V - R and R - H a colour indices of V861 Her.
