Time-Resolved O VI Spectra of CF Tuc and PZ Tel

Observations of the temporal variability of stellar activity provide
important insights into the spatial disribution of stellar active
regions and the configuration of the magnetic field.  We observed the
partially-eclipsing RS CVn system CF Tuc with FUSE through a secondary
eclipse and the ultra-rapid rotator PZ Tel through two stellar
rotations.  We present results from time-resolved spectroscopy of the
C III and O VI emission lines for these stars and for
similarly-observed systems available in the FUSE archives.
