  Time-tag ultraviolet data obtained on the Hubble Space Telescope in 2013
reveal interesting variability related to the white dwarf spin in the two
cataclysmic variables RZ Leo and CC Scl. RZ Leo shows a period at 220s and its
harmonic at 110s, thus identifying it as a likely Intermediate Polar (IP). The
spin signal is not visible in a short single night of ground based data in
2016, but the shorter exposures in that dataset indicate a possible partial
eclipse. The much larger UV amplitude of the spin signal in the known IP CC Scl
allows the spin of 389s, previously only seen at outburst, to be visible at
quiescence. Spectra created from the peaks and troughs of the spin times
indicate a hotter temperature of several thousand degrees during the peak
phases, with multiple components contributing to the UV light.
