Abstract

The observational determination of the electron density and velocity distributions in the solar corona is a basis to any physical modelling. In this context, our program, started in 1973, consists in deriving the large-scale electron density distribution from photographic observations of the polarized white-light corona during total solar eclipses. Since 1991, this program makes use of CCD technologies. We present here results of our 2D descriptive model of the electron density distribution.
