Component frequencies of FM Com were analyzed using 43-hr V-band photoelectric observations. Both conventional Fourier and autoregressive-extrapolation techniques applied to the closely spaced nights of observation yielded variable frequency patterns. Comparison of the observed and synthetic light curves calculated from the two frequencies obtained by analyzing a previously obtained compact data segment supports the suggestion of this star's nonstationary light variation.
