Auroral phenomena can have pronounced effects upon HF radiowave propagation traversing polar regions. To further understand the implications and predict the resulting effects, a continuation of the investigation of auroral phenomena and their impact upon Polar Fox II measurements is presented. In the report, special emphasis has been placed on a study of the fine structure and motions of spread F as related to spectral spreading; the main ionospheric trough and magnetic activity; analysis of radar auroral absorption and Auroral sporadic E as they relate to propagation coverage predictions. Prepared in cooperation with Analytical Systems Corp., Burlington, Mass. (Rept. no. ASCR-72-62).
