Scientific paper

Three color photoelectric observations of the variable W CVn obtained were interpreted. The investigation shows secular change of the period and a stable light curve. Interstellar absorption in the direction of the variable is discussed and the absolute magnitude from the period - luminosity relation was derived. Color - color diagram was constructed and distance of 980 pc for the variable was determined.
