The ‘K-Coronameters’ in use since 1956 at Pic-du-Midi and Meudon Observatories for the study of the white-light corona were replaced in 1963 by new improved instruments.

The coronal activity was continuously recorded from 1964 to 1967. The electron density in the low corona and its variation with height are summarized by curves and maps.

A study is given of the corona streamers above the proton flares area in July and September 1966.
