Solar chlorine abundance from an X-ray flare spectrum
Abstract
The solar coronal chlorine abundance is estimated from a weak X-ray line seen during a flare. The line intensity is compared with a nearby sulfur line with very similar contribution function. The chlorine abundance obtained is very similar to the only other positive determination for the sun, from HCl lines in a sunspot spectrum.
