Abstract

(Abstract only) The Bundesdeutsche Arbeitsgemeinschaft für Veränderliche Sterne was founded 1950 in Berlin. The intention was—and still is—to support amateurs in the systematic observation of variable stars. The history of the German workgroup, the classical working focus (maxima and minima and single estimates), and the main publications (BAV Mitteilungen and Lichtenknecker-Database of the BAV) will be described.
