Abstract: The main results of polarization observations in the 530.3 nm coronal line on July 11, 1991 are discussed. A serious contradiction is revealed between the observations and currently accepted theories; i.e., the radial direction of the polarization vector (electric vector in the wave) predicted theoretically does not agree with the experimental results. The direction of polarization in the green line turns out to be tangential, i.e., the same as in the white-light corona, virtually everywhere except in the bright equatorial regions. The analysis of data obtained by other authors does not provide reliable corroboration of the theory. The conclusions drawn in our work urge that further observational studies be carried out and/or an euristic theoretical approach be conceived.
