We present the results of our observations of the white-light corona in polarized light performed at Criciuma eclipse, Brazil. ![]() During the observation of 3.11.94 we have made five couple of pictures of the solar corona in polarization light. The telescope with equatorial mounting with LOMO lens diameter D = 7.5 cm and focus f = 75 cm used in the observation. To suppress the radial gradient of the coronal emission it was used an mask of diameter d = 3 cm puted between the lens and the film at a distance l = 25 cm from the focal plane. Radius R and the focal length f of the lens were selected in such a way to provide complete blinding of the lens at the moon edge and a full opening of the lens at the distance g from the centre of the 6x6 cm picture. Couples of pictures with exposures 2, 4, 8, 16 and 32 sec were made. Revealed fine structure of the streamers allowed to perform careful analysis of the solar corona structure.
We propose new method of reconstructing the ray structure of the solar
corona for distances more than 1.5 The method based on the calculation of the In the present work we test the assumptions underlying our method of
calculating the coronal sheet near The same conclusion can be derived from the analysis of the polarization of main rays. The greatest of the polarization is observed for the points located along the direction of the maximal extent of the corona.
