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

β¦ Synopsis
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 circumstances, the electron and proton temperatures may differ significantly.

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 K
The differential rotation of the solar corona has been analyzed using as the input data the brightness of the coronal green line Fe XIV 530.3 nm for more than five activity cycles. It is found that the character of rotation of the solar corona changes during the activity cycle. Approximately at the
