In the late 1940s and early 1950s, France and Australia were both very actively involved in solar radio astronomy. One of the problems was to find the resolution to successfully investigate the association of coronal radio emitting regions with sunspots and other photospheric features, and solar eclipse expeditions came to play a key role in this quest. By observing an eclipse from geographically-spaced localities it was possible to accurately determine the positions of the radio-emitting regions, and the overall observations could also be used to investigate the form and size of the radio corona.
Between 1948 and 1952 French and Australian radio astronomers mounted five different solar eclipse expeditions, which contributed significantly to our understanding of the solar corona and radio-optical associations. This poster paper will review these expeditions by examining the personnel involved, their equipment, the observations made and the scientific results.
