An observational search has been made for intensity fluctuations associated with the wave motions that are thought to heat the corona. Brightness changes in the coronal green line (Fe XIV lambda 5303) and the coronal continuum were measured with the University of Hawaii's polarimeter at Mt. Haleakala. Upper limits of fluctuations associated with wave heating were 0.2% and 6% in the line and continuum, respectively. Spectra of quiescent prominences have been analyzed to determine whether any correlation exists between temperature and microturbulence, which could be consistent with wave heating of prominences. Kinetic temperatures range from 8000 to 11000 K, rms turbulent velocities range from 3 to 8 km/s. No correlation between temperature and microturbulence was found. Some evidence for a gradient in kinetic temperature and for gross oscillations of an entire prominence, was found.
