We photographed the spectrum of 32 Cygni during its 1981 eclipse at the various phases of atmospheric, partial and total eclipses and derived the variation of the radial velocity of the K supergiant component with phase. Different lines of the same multiplet on the same plate showed different radial velocities and there is a hint that short time scale pulses may exist on the K supergiant. A preliminary analysis and discussion is given.
