Fe XIV (530.3 nm), Fe X (637.4 nm) and continuum
This color image is a composition of Fe X image (red),
Fe XIV image (green) and
continuum (white light image).
This image is a composition of 225 eclipse images (calibrated using several thousands of dark-frames and
flat-fields) acquired with 5 different instruments - Nikon Z6 camera for white-light
(continuum) images and two pairs of ZWO ASI1600MM Pro cameras for imaging of Fe X and Fe XIV emission.
Continuum is displayed as neutral gray, Fe X and Fe XIV gave the final image colors.
Charged particles are tracers of magnetic field lines. At present, they are the only
tools available to visualize the 'shape' of magnetic field lines in the solar corona, thus yielding
an image of their distribution in the plane of the sky. However, there are limitations when using
ions, such as Fe X and Fe XIV, since they populate different magnetic structures with different
temperatures. Hence, the image of solar magnetic field structures, which they provide, is incomplete.
Fortunately, free coronal electrons, scattering the photospheric light towards the observer, are
omnipresent and therefore the visualization of the solar magnetic field in the white-light (continuum)
image is detailed and complete. That is why the composition presented in this page provides valuable
information about the structure of the solar magnetic field and at the same time visualizes the
distribution of Fe ions.
