Data are presented on the radiation fluxes of the nucleous of Seyfert galaxy NGC 1275, observed with the scanning spectrophotometer on the Crimean Observatory's 1.25-m telescope. Measurements were carried out in three spectral regions: H-beta, the forbidden O III lines 4959 A and 5007 A, and continuum. It was found that the distribution of radiation flux is normal only for H-beta line. The continuum flux distribution curve was bimodal at 2.6 and 8 mm. The flux-distribution curves of H-beta and the forbidden O III lines were different, suggesting different locations of the emission regions of these lines near the sources of excitation.
