Electron Densities in a Solar Flare Derived from X-Ray Spectra.

Abstract

We obtained high resolution solar x-ray spectra during the rising phase of a major solar flare between 0807 UT and 0905 UT on 1979 June 10. Measurements of the density sensitive line ratio, R, of the O VIII 1s squared (1) sub 0 - 1s 2s (3) S sub 1 (22.10 A) flux to the O VII 1s squared (1) S sub 0 - 1s 2p (3) P sub 1 (21.80 A) flux indicates that the density of the plasma at around 2 million K exceeded 10 to the 11th power per cu cm near the peak of the flare.
