THE HELIOSPHERIC LAYER AND THE CORONAL STRUCTURE ON NOVEMBER 3, 1994

The polarization observations of the white corona in 1994 (Crisciuma, Brazil) are presented. The synoptic map of filaments is used to calcul ate the position of the B-r = 0 surface in space at the time of solar eclipse. The structure of coronal streamers is found to correlate well with the folds and wrinkles of this surface, which result from its pr ojection onto the plane of the sky. The measured degree of polarizatio n is compared with the calculations that are based on the model of Sai to (1972). It is concluded that our model is consistent with the obser vations.
