The analysis of 14 high resolution spectra of the chemically peculiar star HR 7775 recorded by the International Ultraviolet Explorer reveals large amplitude variations of the far and mid-ultraviolet flux (at minimum the flux is about 70% of its value at maximum) over the various observations with IUE. The lines at minimum flux are redshifted respect to their positions at maximum. These variations probably reflects an eclipse by a cooler and smaller companion of spectral type A or even early F. The absence of TESS observations prevents a search for periodic orbital and rotational variabilities.
