Scientific paper

From white-light polarized pictures taken by Koutchmy during the 1973 eclipse, brightness curves could be recorded in the north polar hole, in the darkest region between the polar plumes, between 1.3 and 3.2 earth radii. This region is assumed to represent the homogeneous, spherically-symmetric background of the hole. Brightness curves are extended up to 5 radii by those of Munro and Jackson, which lie 1.5 higher in intensity and are thus divided by this factor. A classical inversion gives the electron density and the brightness of the F-corona. Adopting the geometry of Munro and Jackson for the extension of the hole allows the solar wind speed to be calculated.
