Evidence for a very hot companion to the star SAO 181201, the nucleus of the old planetary nebula Abell 35, was found. The IUE spectra at short wavelengths which show strong absorption features from H I and He II suggest that the companion may by a DAO white dwarf with an effective temperature that may be as high as 150,000 K. Except for its even steeper rise towards shorter wavelengths, the SWP spectrum of the nucleus of A 35 is very similar to the spectrum of PG 1159-035, which is the prototype object of the group of pulsating white dwarfs. It is suggested that periodic light variations at optical wavelengths of SAO 181201 (with a most likely period of 1102 min) are related to periodic light changes of its hot companion.
