Scientific paper

We report detection of the second and third spectrum in the visual and SB1 system HD 216608. Lines of both new components are very sharp and are clearly travelling and crossing. They probably both belong to the visual B companion of HD 216608A. These sharp lines cause heavy blends of the third broad line spectrum which we ascribe to the HD 216608A. Consequently, the orbit and SB1 nature of HD 216608A is questioned while HD 216608B seems to be a new SB2 system.
