Hmm...yes, possibly, was there really life before Skylab?! In fact I studied the coronal visible lines (1952 eclipse observations) for my PhD thesis many, many years ago!! Yellow is CaXV, seen only in very active active region, green is FeXIV and red is FeX. Green should be 'fuzzier' than red. Not sure if this was the case. I'll check it out. Helen

Ah yes. I'd already copied this from somewhere! It looks like a nice piece of work, but I noticed a misunderstanding of the history of the "fuzzy hot corona". This could already be seen in the visible forbidden lines - yellow being fuzzier than red or green. See the Billings book, which came long before Skylab.
