We have obtained photometric and spectroscopic observations of the sus
pected cataclysmic variable stars VW Tucanae, Phe 1, and Scl 2. VW Tuc
and Phe 1 are confirmed as cataclysmic variables (CVs). VW Tuc has th
e spectrum of a ''normal,'' disk-accreting CV. Phe 1 is a double-lined
spectroscopic binary that may have a short orbital period-a time-reso
lved spectroscopic study of the kinematics in this system could have i
mportant implications to the understanding of CV structure and evoluti
on. Scl 2 appears to be a non-CV composed of a late-type dwarf emissio
n (dMe) star with a (noninteracting) while dwarf or hot subdwarf compa
nion.
