11. The lack of a solar corona during solar eclipses was also noted prior to 1715. 12. Its main instrument will be a coronagraph for studying the dynamics of the Solar corona . 13. The temperature jumps up rapidly to nearly one million kelvin, the temperature of the solar corona . 14. This phenomena is sometimes called the solar corona . 15. He also made studies of the solar corona , using photographs from the 1914 solar eclipse expedition. 16. The sun's surface, or atmosphere, is divided into three regions : the photosphere, the chromosphere, and the solar corona . 17. Habbal said that magnetic fields in the solar corona will affect the radio signals on their way to Earth. 18. These coronagraphs monitor the solar corona by using an optical system to create, in effect, an artificial solar eclipse. 19. With this higher cadence, SWAP will monitor events in the low solar corona that might be relevant for space weather. 20. She studied the fine structure of the solar corona and its inner movements based on eclipse data between 1887 1941.
