Abstract

CH Cyg was observed visually by Professor Władysław Dziewulski in the years 19301940 at the Vilno Observatory, with the 15 cm refractor using Argelander’s method. As a skillful and experienced observer he achieved the accuracy of his single measurement of about 0.05 mag. The series of his 652 estimates of CH Cyg has been recently reduced and is discussed in this paper.
