Solar Brightness Distribution at a Wavelength of 60 Centimetres. II. Localized Radio Bright Regions

Abstract

The localized radio bright regions on the Sun which give rise to a slowly varying component of the solar radiation were studied at a wavelength of 60 cm, using a 32-aerial interferometer with a beamwidth of 8·7 min of arc. The observations were undertaken during July 1954 to March 1955 and were limited in number due to this being a minimum period of the solar cycle. The low activity, however, provided the advantage of simple interpretation as often only one region was present on the solar disk.
