Number 43 (Story #2), August 1, 1991 by Phillip F. Schewe and Ben Stein THE RECENT SOLAR ECLIPSE has already borne fruit. For example, an infrared telescope on Mauna Kea has found (Drake Demining, NASA Goddard, 301-286-6519) that a magnesium emission line---long related to magnetic activity in the Sun's atmosphere but only poorly located in terms of altitude---originates in the upper photosphere and not in the overlying chromosphere. Other Mauna Kea astronomers (Eric Tollestrup, Harvard-Smithsonian) have recorded the first infrared picture of the eclipsed Sun. They failed to observe any sort of dust ring such as might have formed from dismembered comets or from the residue of material left over when the solar system first formed.
