Scientific paper

Many quasi-simultaneous optical observations of four BL Lac objects were obtained at the Yunnan and Shanghai Observatories. In this paper, data for the optical spectral index of four BL Lac objects are presented. Our results show that the optical spectral index of these BL Lac objects is characterized by variability. The optical spectra of the BL Lac objects H0323+022 and ON 231 flatten when the sources brighten, whereas they steepen for the objects S5 0716+71 and OJ 287.
