AB: The mechanisms by which solar prominences are filled with plasma are still undetermined. In this study we perform a quantitative analysis of the thermal properties of moving features in prominences in order to put constraints on models of prominence formation and dynamics. In order to make such measurements of moving features seen in prominences in the UV we use the SOHO spectrometers SUMER and CDS to take a time series of exposures at a single pointing position, providing a measurement of spectral line properties as a function of time and position along the slit. The resulting observations in spectral lines in a range of "transition region" temperatures allow us to analyze the evolution of thermal properties of quickly moving prominence features as a function of time.
