N2 - The first image of the corona in the Fe XI 789.2 nm line was obtained
during the total solar eclipse of 29 March 2006. Observations of the
same spectral line, in conjunction with other more regularly observed Fe
lines, such as Fe X 637.4, Fe XIII 1074.7 and Fe XIV 530.3 nm, were made
during the eclipse of 1 August 2008. During both eclipses, the Fe XI
emission extended further out in the corona than the other Fe lines. The
other striking features in both Fe XI observations was the presence of
localized enhanced emission when compared to white light, and coronal
structures more readily observed in Fe XI than in white light. The
results from both eclipses will be presented, with particular emphasis
on their implications for coronal heating mechanisms and the coronal
electron temperature.
