Results are reported for two-color (B and V) photoelectric photometry of the peculiar variable triple system V389 Cyg (= HD 201433). The total range of the light variation is determined to be of the order of 0.16 mag in V, and the (B-V) variation is shown to be only marginal. No significant periods are found in the data, nor is any correlation with the 154-day orbital period discerned.
