I really can't comment on the article, but for for interest sake you should
check out the SOHO (Solar and Heliospheric Observatory) website:

http://sohowww.nascom.nasa.gov/

(Click on "Latest Images" for current pix)

Several of the extreme ultraviolet imaging telescope (EIT) sensors rely on
emissions from ionized iron (_really_ ionized iron, like Fe XII!).

It's also a good web site if you want to get movies of solar flares, coronal
mass ejections, etc. I've used a few of these in my class.
