Scientific paper

During the July 91 total solar eclipse, the polarized K corona was observed from two sites in Baja California (Mexico) using two techniques: photography with a 6 position polarizing filter (30 deg steps) and CCD (Charge Coupled Device) camera using 12 positions (15 deg steps). A total of 36 CCD images were combined to produce intensity and polarization maps of the corona from 1.1 to 3.0 solar radii with 10 inch spatial resolution. Several characteristics of the corona can already be deduced from those data, which are now processed to compute the global electron density distribution.
