The Sun's outer corona at radio wavelengths.
Abstract
The use of meter-decameter wavelength imaging observations to follow four different kinds of studies of solar coronal activity is discussed. The Clark Lake Radio Observatory's multifrequency radioheliograph which operates in the 20-125 MHz frequency range is described. This paper emphasizes the differences observed in coronal phenomena with instruments having a higher sensitivity than the Culgoora instrument. New observations from the Clark Lake radioheliograph which show details of the long-lived structure of the corona are presented. These are then compared with features of the optical corona as shown in the data obtained by satellite-borne and ground-based coronagraphs.
