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.
