Statistical spectral analysis of the radiation power of R Cr B has revealed three harmonic components of variability with periods P1 = 53.64 days, P2 = 39.96 days, and P3 = 27.36 days. One of them synchronizes the times of beginning of global and secondary fadings of the light, which strengthens the physical similarity between R Cr B and RY Sgr.
