Abstract: FUSE and HST/STIS Observations of the post-common envelope (CE) pre-cataclysmic variable (CV) binary HS1136+6646 have revealed a preintermediate polar (IP) candidate. These UV observations have made it possible to accurately measure the system parameters of the binary system which previously could only be estimated using optical data. Radial velocity measurements over an entire orbital cycle have revealed the binary system to contain a 0.83 MSolar white dwarf primary with a gravitational redshift of 45 kms−1. The mass of the secondary star and inclination of the binary system has also been determined to be 0.36 MSolar and 71.8° respectively. With the white dwarf suspected of possessing a moderate magnetic field, this binary system is among the only suspected pre-CV systems to be a pre-intermediate polar candidate.
