Interferometric Eclipse Observations of Coronal Fe XIV Emission

Abstract

An experiment carried out during the February 16, 1980 total solar eclipse to measure velocities and intensity distributions associated with coronal loops is described. The optical instrumentation used consisted of a 30-cm aperture Cassegrain telescope, a solid fabry-Perot etalon, ancillary optical components and a motor-driven camera. During totality, the green corona was photographed both with and without the etalon in thte system; the first maximum of the etalon beyond the limb was recorded on three frames. A preliminary discussion of the data is presented.
