Orientation of the linear polarization plane of H-alpha emission in prominences
Abstract
2D distributions of deviations of the polarization plane from the direction tangential to the solar limb (angle ) and the sign of are presented for Hα prominences of March 29, 2006. The obtained values of are in agreement with non-eclipse coronagraphic measurements and indicate the existence of longitudinal magnetic fields. The 2D distributions of the sign of show the existence of both + and - polarities for each prominence. An interpretation in the frame of the existence of oppositely directed magnetic fields is noted.
