CORRELATION BETWEEN SOLAR X-RAY LINE EMISSION AND SOLAR-RADIO EMISSION.
Abstract
The intensities of a number of solar x-ray emission lines in the 8- to 25-A region have been compared to solar-radio emissions at several wavelengths to search for a correlation between the two and to try to identify a slowly varying component of the x-ray emission lines. The x-ray measurements were made from the OV1-10 satellite from December 1966 to June 1967 with a Bragg crystal spectrometer. The radio measurements at six frequencies between 606 and 8800 MHz were taken from reports in the literature. In general, the highest correlation coefficients (r is about 0.80) occur at the longer radio wavelengths for the shortest x-ray wavelengths, and the shorter x-ray wavelengths correlate best with the shortest radio wavelengths. The high correlation coefficients obtained strongly suggest a close relationship between the radio and x-ray emissions. These highly correlated x-ray and radio emissions are referred to as the slowly varying component. The same active regions appear to be responsible for both the radio and x-ray emissions. (Author)
