This book was released on 1965 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Use has been made of recent satellite measurements of solar flare X-ray flux, and where available its spectral distribution, for detailed quantitative examination of the accompanying Sudden Ionospheric Disturbances, principally Sudden Cosmic Noise Absorption (SCNA). From observed or assumed spectral distributions of the X-ray flux, profiles of ion production rates are obtained for a few specific events. A comparison of these production rates with the observed excess attenuation during the peak of the SCNA leads to an upper limit for the value of the effective dissociative recombination coefficient alpha sub c when negative ions are ignored. These limiting values were found to range between 0.0000001 to 0.000001 cc/s. When the effect of negative ions is considered, alpha sub c is reduced to values around (1-4) x 10 to the minus 8th power cc/s. An extension of the above method involves the simultaneous use of SCNAs and SPAs at very low frequencies, along with X-ray spectral data. When this is done, it is possible to obtain information on both the dissociative recombination coefficient and negative ions. (Author).

Download or read book A Comparison of Sudden Ionospheric Frequency Deviations with Solar X ray and Centimeter wave Emission During October 1963 written by Donald Milford Baker and published by . This book was released on 1967 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 (0.50-10 Å) 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.
