  Solar corona has been judged to consist of free electrons and highly ionized
ions with extremely high temperature as a widely accepted knowledge. This view
is changed by our eclipse observations. Distributions of cool matter
represented by neutral iron atoms in hot inner solar corona are presented via
derived global maps of solar Fraunhofer(F-) and Emission(E-) coronae, compared
with those of continuum(Kontinuierlich, K-) corona formed by free electrons.
The maps are obtained from simultaneous observations of dual filtering bands
centered respectively at 659.4nm and 660.1nm, performed from twin telescopes
during the total solar eclipse on April 20, 2023 at Com town of East Timor,
assisted for judgement via spectral images obtained by a portable spectrograph.
They show respectively presences of these neutral iron atoms yielding 659.3nm
and 659.4nm lines in both the quiet sun and active regions. The distribution of
the cool matter in form of line depression forms an inner F-corona, different
from that of the cool matter in form of line enhancement. Both the
distributions show a crucial difference from that of the free electrons
represented by the K-corona map. It is also found that intensities of the
F-corona and the E-corona induced by these neutral atoms are only small
fractions of the K-corona, and the diffusion can be seen clearly in all these
maps. They uncover also that the coronal heating resources do not distribute
pervasively but likely form a thermodynamic griddle where minor photospheric
neutral atoms can escape from the heating into the corona globally.
