Abstract

An extensive photometric dataset has been compiled for six Luminous Blue Variables (LBVs). The dataset comprises published and unpublished measurements in the Stromgren, Geneva and Walraven photometric systems. The measurements within each individual system are presented in a uniform manner. Combining observations from these three photometric systems, a V j light curve has been constructed for each LBV. Examination of the light curves reveals variations on widely different magnitude and time scales
