The Monochromatic Sun in the Extreme Ultraviolet
Abstract
A set of spectroheliograms of the sun taken during an Aerobee rocket flight made on April 28, 1966, by the U.S. Naval Research Laboratory is the primary source of observational data. The wavelength range covered was approximately 170-600A. A coronal enhancement at the east limb was sufficiently intense, and free from contamination by other features and background continuum to permit a photometric study of its brightness profile in several of the more intense lines. A study of the maximum brightnesses of the enhancement in several lines of widely varying temperatures gave a measure of the ability of the enhancement to emit radiation as a function of temperature. A comparison of the measured emission scale heights with the scale heights predicted by hydrostatic equilibrium yielded information of the magnetic field structure governing the different temperature regimes.
