A Comparison of Solar EUV Intensities and K-Coronameter Measurements
Abstract
Characteristics of the emission observed above the solar limb in four EUV lines, SIXIIλ499, MgXλ625, NeVIIIλ770, and OVIλ1032 are discussed. The mean temperature of the corona derived from the ratios of the intensities of SIXIIλ499 and MgXλ625 is 1.8 million K. There do not appear to be significant temperature differences in regions with low EUV intensities and those with high EUV intensities, suggesting that the EUV emission from the lithium-like ions depends primarily on the integral of ne2 along the line of sight.
