Abstract
The analysis of four spectra of the B7 He-weak star HD 35456 recorded by the SWP camera on board the International Ultraviolet Explorer does not reveal any variations of the far-ultraviolet spectral energy distribution shortwards of 1700 Å over slightly more than one rotational period. There is no sign of variability in the numerous Si ii, Si iii and Si iv lines present in the far-ultraviolet. The profile of the resonance line of C ii at 1335 Å remains constant too.
