Abstract
Abstract The analysis of three spectra of the Mn Hg Sr star HD 14228 recorded by the SWP camera on board the International Ultraviolet Explorer does not reveal variations of the far-ultraviolet flux over a nine years time interval. The analysis of the TESS lightcurve of HD 14228 confirms a very short period of 0.34 day already reported in the literature. This periodicity, attributed to rotation, could be a mode of radial pulsation too.
