Maps of the 2-D distribution of coronal electron temperature and ion charge state. (S Habbal et al.)

These images of the solar corona show the near-infrared emission from highly ionized iron lines for eclipses in 2006 (left) and 2008 (right), with white-light images added below. Red indicates iron line Fe XI (789.2 nm), blue, iron line Fe XIII (1074.7 nm), and green iron line Fe XIV (530.3 nm). These are the first maps of the 2-D distribution of coronal electron temperature and ion charge state and show that the localization of specific iron emission persists as much as three solar radii from the Sun. This extensive mapping establishes the first direct link between the distribution of charge states in the corona and in interplanetary space. The results are published by Shadia Habbal and co-workers in Ap. J.
