An interferometric investigation of emission lines from the solar corona

Abstract

The profiles of the Fe xiv, ?5303, and Fe x, ?6374, emission lines of the solar corona have been observed at different positions using a photoelectric scanning Fabry-Perot interferometer. These profiles were obtained during the eclipse of 7th March 1970, in Mexico and at the Pic-du-Midi coronagraph in October, 1970. The half-widths of these profiles were determined for both the coronal lines and temperatures were derived from these widths. No systematic temperature variation was discovered, however there was some suggestion of the existence of a fluctuation with time in the width of the emission lines. © 1973 D.
