| | Changes in the Lower Ionosphere during the Eclipse—A Preliminary Report of the Canadian Programme: (1) Introduction 1100
Ground-based radio investigations and four rocket launches were carried out in Canada to study the effect of the eclipse on the solar radiation and electron densities in the lower ionosphere (below about 150 km). The following four articles describe the experiments.
