Abstract
We present V light curves of P Cygni from JD 2446200-9300 (1985-1993). Inspection of the light curves, and Fourier and autocorrelation analy sis, show that the star varies on time scales of about 40 to several h undred days. No one time scale stands out, though 40, 120 and 160 days are noticeable in the autocorrelation diagram of the combined 1985-19 93 data.
