Scientific paper

The results of photometry of five symbiotic stars, AX Per, AG Dra, BF Cyg, V 443 Her, and YY Her, are presented. The observations showed the absence of fluctuations in the IR brightness of these stars exceeding 0.3 m. At the same time, considerable fluctuations (greater than 1 m) in the UV emission of AX Per and AG Dra are noted. The physical parameters of the individual components (hot star, cool star, and ionized gas) of the AX Per, AG Dra, and BF Cyg systems are estimated.
