IF “my mathematical result was based upon data among which the principal point at issue was accepted as proved,” it will be easy for you to state what that point is,* and to quote one passage at least in which Mr. Lockyer has associated it with his theory. In this way alone can you justify the assertion in your last editorial note.

Plasma Corona and Dust Corona of the Sun
1994Concerning the structure of the heliomagnetosphere, the 4—sector model with four vertical sector boundaries was proposed by Wilcox et al.(1965). In contrast to this model, the current sheet model(Shulz, 1973), or the two-hemisphere model(Saito, 1975) with the one warped horizontal neutral sheet were proposed (see the review by Saito et al., 198 9a).

The magnetic field in the Sun's corona
Science, 2020Solar Physics The solar corona is the outermost layer of the Sun's atmosphere, consisting of hot, diffuse, and highly ionized plasma. The magnetic field in this region is expected to drive many of its physical properties but has been difficult to measure with observations. Yang et al.

Total solar eclipses provide a unique view of the faint solar corona, without the bright over-powering emission from the solar disk, enabling us to explore the electron density, temperature, thermodynamics, and related fundamental physics (Habbal et al. 2010a, 2011, 2013).

Periodicities in the green corona for the sun as a star
Solar Physics, 1990A coronal index (CI) derived from the limb observations of the 530.3 nm emission corona (green corona) over 1964–1987 was analyzed by the Fourier transform technique (FTT) to find periodicity in this layer of solar atmosphere. As expected, two pronounced periods were indicated: the rotational, about 27 d, and the activity cycle length, 11 years. Beside

Differential rotation of the corona of the Sun as a star
AIP Conference Proceedings, 2009The brightness of the solar corona as a whole (limb+disk) in the green line (Fe XIV 5303 A) is estimated from the database created by J. Sykora. This coronal index GLS (Green Line Sun) is based on observations directly. A daily set of from 1939 to 2001 is analyzed with the adaptive wavelet techniques.

Why Is the Sun's Corona So Hot?
Science, 2012How does heat dissipating from the sun's core out beyond the surface to its corona abruptly punch temperatures up by a factor of 200 and more?

Magnetic waves pervade the Sun’s corona
Physics Today, 2009Alfvén waves manifest magnetism’s dominance of coronal dynamics. Whether they heat the Sun’s corona remains uncertain.
