Brightness of calcium emission regions associated with the solid material sublimation in the near circumsolar space
Photometric reduction of the Ca II K-line interferogram obtained during the total solar eclipse on February 26, 1998, has been carried out. The interferogram covering the circumsolar region of the sky includes K-line emission features due to the solid material sublimation close to the Sun. The number of emitting Ca II ions and the total mass of sublimated material are estimated. Results of such investigations should be significant for cosmogonical research.
