✦ Synopsis

Observational line width evidence for a possible discrepancy between ion and electron temperature in the corona is reviewed for comparison with the conclusions of Knight et al. We note that the high line-width temperatures extend much higher in the corona than the high ion temperatures computed by Knight et aL, and suggest that a significant ion-electron temperature difference should be expected only near a steep temperature gradient, as in the transition region.

A simple model of the lower corona which allows for a possible difference in the electron and proton temperatures is analyzed. With the introduction of a phenomenological heating term, temperature and density profiles are calculated for several different cases. It is found that, under certain circum

We appreciate Billings' informative commentary on the problem of the temperature structure of the solar corona. We regret that we were unaware of the article by which first suggested that a large ion-electron temperature difference might result from a combination of nonthermal heating of the ions a
