Abstract
The first image of the corona in Fe XI 789.2 nm was taken during the
total solar eclipse of 29 March 2006. It revealed a number of surprises,
primarily an emission extending out to at least 3 Rs and localized
regions of enhanced Fe^10+ ion density relative to electrons. Subsequent
observations of this spectral line were successfully made during the
eclipses of 2008 and 2009. These Fe XI observations will be presented,
together with simultaneous eclipse observations of the more widely
observed Fe X 637.4, Fe XIII 1074.7 and Fe XIV 530.3 nm lines.
Particular emphasis will be placed on the new insights gained by this
suite of measurements into the thermodynamic properties of the inner
corona.
