Several recent observational results suggest that coronal mass ejection (CME) plasma is heated even after leaving the flare site. The source of the heating is probably the magnetic field, but the mechanisms that convert magnetic to thermal energy during these events are not well understood. We perform a time-dependent ionization analysis of a CME observed by SOHO/UVCS on 2000 June 28 to constrain plasma heating at distances of up to several solar radii. The most strongly constrained feature shows cumulative plasma heating comparable to or greater than the kinetic energy, whereas features observed early in the event showed plasma heating comparable to or less than the kinetic energy. We use these results to assess the efficacy of several candidate mechanisms, including heating by the CME current sheet, small-scale reconnection, MHD instabilities, thermal conduction, energetic particles, and wave heating.
