Abstract:
In this talk we will discuss the diagnostic potential of observations
of visible spectral lines formed in the extended solar corona that can
be obtained during eclipses. We will discuss the possible diagnostic
applications of visible eclipse observations to measure the physical
parameters of the extended corona, to understand solar wind origin and
acceleration, and to determine the evolution of Coronal Mass Ejections
during onset.
We will first review the mechanisms of formation of spectral line
intensities, we will then illustrate their diagnostic applications,
and show some results from recent eclipse observations. We will also
review the spectral lines that are most likely to be observed in
the extended solar corona during the upcoming 2017 eclipse in the
continental United States.
