Abstract: V645 Cyg - a young massive star, which probably appear from a parrent material just recently. In previous work we found the simultaneous reddering and brightening of VRI magnitudes during decades. In the optical spectra the absortion component of the blue wing of the Hα line became more evident. In the current work we fit the absorbtion components of the Hα and He I 5875 Å. We found the velocity variation of these A lines by gaussians. components wich correlate with each other.
