The Distribution of Radio Brightness Over the Solar Disk at a Wavelength of 21 Centimetres. IV. The Slowly Varying Component

Abstract

A large number of highly emitting regions on the Sun have been studied individually by means of a 32-element interferometer which produces fringes 3 min of arc wide at a wavelength of 21 cm. These regions are responsible for the slowly varying component of the solar radiation at decimetre wavelengths.
