Study of the Three Centimeter Radio Frequency Emanation from the Solar Atmosphere.
Abstract
Two-dimensional radio contour maps were made of McMath Regions 12397 and 12417 at a wavelength of 2.8 centimeters. On 3 July 1973, Region 12417 was found to have a radio diameter of 15 arc-seconds and a true radio brightness temperature of 5 million K. The thermal bremsstahlung and gyro-resonance emission mechanisms for the 2.8 centimeter slowly-varying component are discussed; the gyro-resonance emission is apparently dominant. The link between the high radio temperatures and solar flares is not clear, but the only regions to exhibit solar activity also had radio temperatures in excess of 5 million K.
