Near-Sun observations of an F-corona decrease and K-corona fine structure [PDF]
Nature, 2019 Remote observations of the solar photospheric light scattered by electrons (the K-corona) and dust (the F-corona or zodiacal light) have been made from the ground during eclipses1 and from space at distances as small as 0.3 astronomical units2-5 to the Sun.

Nature, 1889 A GENERAL statement of the successes of the Western Eclipse Expeditions on January 1 has already appeared in NATURE. More photographs of the corona were taken than ever before—many of them indifferent and worthless, but an unusually large number of great excellence. The best that I have so far seen were taken with 5-inch telescopes, by Mr. W.

Discovery of the Sun's million-degree hot corona [PDF]
Frontiers in Astronomy and Space Sciences, 2014 As time goes by, discoveries become common knowledge, and often the person who first changed a paradigm gets forgotten. One such case is the discovery that the Sun’s corona is a million degrees hot – much hotter than its surface. While we still work on solving how the Sun heats the corona, the name of the discoverer seems to be forgotten.

Outflow from the sun's polar corona
The Astrophysical Journal, 1983 New observations of systematic Doppler shifts of EUV resonance lines formed both in the low corona and transition region are reported. They were made with an improved, high-resolution, stable, rocket-borne spectrometer flown on 1981 November 23. The chord of the solar disk scanned by the spectrometer crossed the north polar cap hole and its low ...

Current sheets in the Sun’s corona [PDF]
, 2005 Current sheets play an important role in the Sun’s atmosphere, especially in coronal heating events and solar flares. They may form in response to motions of the magnetic footpoints in the solar surface or following a loss of equilibrium.

Energy Input Flux in the Global Quiet-Sun Corona [PDF]
The Astrophysical Journal, 2017 Abstract We present first results of a novel technique that provides, for the first time, constraints on the energy input flux at the coronal base (r ∼ 1.025 R ⊙) of the quiet Sun at a global scale. By combining differential emission measure tomography of EUV images, with global models of the coronal magnetic field, we ...
