Summary

The project is an effort from an aircraft platform at the toal solar eclipse of 18 February 1998 with the following objectives: 1) To survey the intermediate infrared spectral region for coronal emission lines, toward the goal of adding diagnostic capability in coronal studies; 2) to carry out photometric measurements of the IR coronal radiance, so as to specify the relative roles of thermal emission and scattering from the F-coronal dust; 3) to measure the spectral shift of Fraunhofer lines in the coronal signal in order to determine the motion of interplanetary dust near the sun and to understand previously reported variations from Keplerian orbital mootion; and 4) to sudy the HE I 1083 nm radiation observed at the 1994 eclipse inthe outer coronal by means of line profile measurements. This project was headed by Robert MacQueen to study the Infrared Solar Corona from Panama City, Panama.
