Abstract

V389 Cygni is one component of the multiple system ADS 14682. The remarkable conclusions reached by Guthnick in 1942, in regard to the interpretations of seemingly incompatible radial velocity and photometric periods, have never been challenged or confirmed. New data, especially photoelectric observations, are needed for a better understanding of this enigmatic object.
