Abstract:

An application of a semiempirical method to obtain quantitative values of the brightness of the earths halo as it would appear to an observer in space experiencing a central total solar eclipse with the earth as the eclipsing body. Results are presented for a range of radial altitudes from 10,000 to 255,000 km. Both the luminance or surface brightness of the atmospheric halo and the total brightness or illumination received by an observer within this altitude range are given. Extensive appendixes fully discuss the mathematical treatment, including the implicit assumptions and estimates of the probable accuracy. Author
