Abstract

During the total solar eclipse of 11 June 1983 over Java, Indonesia, a dual-channel Fabry-Perot interferometric system was used to study simultaneously the coronal emission lines at 5303 Å (Fe xiv) and at 6374 Å (Fe x). The two coronal lines were spatially separated by a multilayer interference beam splitter; the beams then entered two separate optically contacted Fabry-Perot systems operating off-axis. The resulting interference fringes were imaged on fine-grain film. Initial results indicate an emission corona confined largely within 1.2 R. Doppler temperatures derived from the width of the 5303-Å line appear to be appreciably lower than similar temperatures determined during the solar-maximum eclipse of 1980.
