Conditional Climatology of Ap: The Relationship between Various Solar Events (Surges, Prominences, Filaments, Radio Bursts, X-Ray Episodes) and Geomagnetic Storms.

Abstract

This report is a continuation of USAFETAC/TN-90/001 (AD-A222574). This report documents the relationship between Goettingen's planetary geomagnetic index (Ap) and various other solar events, such as surges, prominences, filaments, radio bursts and X-ray events. The study is based on solar and Ap data with an 11-year period of record (1975 to 1986--Solar Cycle 21). Solar reports were merged with 3-hour Ap values for 7 days after each event. The resultant datasets were analyzed with respect to type, position on the sun, and size. Contingency tables of means and percent frequency distribution summarize the results.
