We present V light curves of P Cygni from JD 2446200-9300 (1985-1993). Inspection of the light curves, and Fourier and autocorrelation analysis, show that the star varies on time scales of about 40 to several hundred days. No one time scale stands out, though 40, 120 and 160 days are noticeable in the autocorrelation diagram of the combined 1985-1993 data.
Key words: stars: P Cygni; stars: variable
