Some astronomers once thought these indicated a new element, "coronium." Others suspected were light elements like oxygen in a high state of atomic excitation...
Whether the sun contains a mysterious element "coronium," unknown to the earth, or whether the phenomenon giving rise to the coronium theory is merely the reaction of a well known element such as oxygen under peculiar conditions on the sun, is one of the many important scientific problems which the Harvard-Technology instruments have been designed to solve...
...spectacular corona, trapped in spectroscopes during the scant seconds of a total eclipse, has produced on the spectrogram five mysterious bright lines. Astronomers deduced that the corona, though mostly scattered sunlight, was partly self-luminous. What element made it so? Not knowing, they called it "coronium." As recently as last year, in a standard work on eclipses, "coronium" was treated with respect. The Menzel-Boyce report unmasks it as mostly oxygen in bizarre atomic metamorphoses. The normal oxygen atom has eight orbital electrons. Menzel & Boyce proceeded to imagine oxygen atoms in such a state of excitation that electrons could skip...
...neutral oxygen atom in the high solar atmosphere and under a peculiar state of excitation has been definitely found to coincide with analysis of three of the strongest coronal lines. For years "coronium" a purely hypothetical element, had been considered the cause of the radiations from the sun's corona, just as the light of nebulae was long attributed to the mythical "nebulium...
...this condition, its pearl-white corona is visible, with vivid scarlet flames streaming from it. The corona was once thought to be only reflected sunlight, but modern observers know it has gaseous structure; contains an unknown element which gives a green ray in the spectroscope. This element is called "coronium" for convenience...
