A further contribution to the interpretation of the results of the July 31, 1981 prominence eclipse
Abstract
It is shown that the prominence brightness distribution at a wavelength of 1.35 cm is in better agreement with the Ca II-line brightness distribution than with that of the H-alpha line. The prominence was both active and long-lived. It is suggested that shock excitation is the underlying mechanism in the Ca II line, while H-alpha emission involves a radiative mechanism.
