Abstract

Photographic magnitudes are presented for the irregular variable WW Vulpeculae. They were derived from Argelander brightness estimates carried out on N = 2774 plates of the Harvard College Observatory Plate Collection. The data set is available at the CDS and the period 1898 to 1966. Although the accuracy of the magnitudes is not high, the data may be useful for the study of the long-term behaviour of the light variations of the variable.
