Spectropolarimetric observations of the extreme-ultraviolet (EUV) source and high-field magnetic white dwarf EUVE J0317—855 ( = RE J0317—853) in the wavelength range 4200–7200 Å reveal a strongly structured circular polarization spectrum with a peak polarization of 8 per cent. The strongest features in the polarization spectrum are attributed to Hα 2s0-3p1, 2s0-3p0 and Hβ 2s0-4f-1, 2s0-4f0 and 2s0...
