A Comparison of Sudden Ionospheric Frequency Deviations with Solar X-Ray and Centimeter-Wave Emission During October 1963

摘要

A simple model is developed which permits us to calculate the sudden ionospheric frequency deviation which would be caused by a known solar X-ray burst, or vice-versa, to calculate the time profile of the X-ray burst responsible for an observed frequency deviation. This model is also used to compare the frequency deviations observed during six solar flares with the time profiles of the solar emissions at centimeter and X-ray (0.5-10 A) wavelengths which accompanied the flares. Better time and spectral resolution are needed in order to permit a detailed comparison of the variations in the X-ray flux with the ionospherically induced frequency deviations. (Author)
