Scientific paper

Photometric and spectroscopic observations reveal the Sloan Digital Sky Survey cataclysmic variable SDSS J132723.39+652854.2 to be a likely SW Sex star with an orbital period of P=3.28 hr. The Sloan Digital Sky Survey spectrum shows strong He I, He II, and Balmer emission lines. Time-resolved spectra acquired at Apache Point Observatory reveal absorption-line structure within the emission lines near phase 0.5. Photometric data obtained at Manastash Ridge Observatory using Harris V and B filters reveal a high-inclination system (i=80deg) with deep (~2 mag) eclipses. The orbital period and the spectral variations favor an SW Sex interpretation.
Based on observations with the Apache Point Observatory 3.5 m telescope and the Sloan Digital Sky Survey, which are owned and operated by the Astrophysical Research Consortium (ARC), and the Manastash Ridge Observatory 0.76 m telescope owned and operated by the University of Washington. Observations were also done with the Steward Observatory 2.2 m telescope.
