These images of the solar corona are color overlays of the emission from highly ionized iron lines for the 2006 eclipse (left column) and 2008 eclipse (right column), with white-light images added in the bottom row. Red indicates iron line Fe XI 789.2 nm, blue represents iron line Fe XIII 1074.7 nm, and green shows iron line Fe XIV 530.3 nm. These are the first such maps of the 2-D distribution of coronal electron temperature and ion charge state.
