We have carried out optical and Far UV studies of the field around the EUV source EUVE J1027+323. We find two sources which contribute to this flux which are spatially unresolvable with EUVE. One is a non-cataloged QSO and one is a “hidden” hot white dwarf. Reasonable scenarios ascribe the majority of the flux to the white dwarf.
