The analysis of two spectra of the Mn Hg star HD 29589 recorded by the SWP camera on board the International Ultraviolet Explorer does not reveal variations of the far-ultraviolet flux over a thirteen years time interval. The TESS lightcurve of HD 29589 shows a complex pattern of oscillations with variable amplitudes and probably several periods. A very strong resonance line of Ga II is present at 1414.40 Å and confirms the Hg Mn status of HD 29589. A P Cygni profile at 1793.20 Å on SWP04948 could correspond to the resonance line of Sr II at 1793.09 Å and indicate transient mass loss.
