Abstract
The analysis of twenty-four high resolution SWP spectra of the magnetic Bp star HD 79158 (36 Lynxis) recorded by the International Ultraviolet Explorer (IUE) reveals that the far-ultraviolet flux of this star mostly remained constant over the various observations with IUE. Only a few spectra show less flux shortwards of 1600 Å and enhanced line absorption compared to the mean spectrum, which could be interpreted as non uniform distribution of certain chemical elements over the surface of 36 Lynxis. The TESS lightcurve of HD 79158 reveals a complex structure with an estimated rotational period of about 3.832 ± 0.019 days, close to previous determinations.
