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