Abstract
Our spectroscopic monitoring of the hypergiants HD 168607 (B9.5 Ia-0) and HD 168625 (B5.5 Ia-0) with resolutions from 15000 to 70000 confirms that both stars belong to the Ser OB1 association, proves their spatial closeness, and increases the probability that they constitute a physical pair.
