Correlation of Solar and Geomagnetic Observations with Conditions of the Ionosphere
Abstract
A study was made of the correlation of solar and geomagnetic observations with conditions of the ionosphere, during July 1942 through June 1943, to gain information regarding solar, geomagnetic, and ionospheric relationships and to improve the technique of short-term forecasting of ionospheric disturbances. Electron-density of the ionospheric regions affecting long-distance radio communication diminished as the minimum of the 11-year cycle of activity approached. Solar corona of high intensity, and observed activity of flocculi on the disk were found apparently the most promising criteria for anticipation of magnetic disturbances. The beginning of the new sunspot-cycle indicated an early increase of solar, magnetic, and ionospheric activity.
