A Search for Superhumps in the Cataclysmic Variable SW Sextantis
  We present differential photometry of the cataclysmic variable star SW Sextantis. A time series analysis was performed in search of superhumps in the accretion disk of this star, which is the prototype of a class of cataclysmic variables, the SW Sex stars. We find no superhumps, which shows that the presence of superhumps is not a defining feature of the SW Sex stars.
