- Аннотация: 2D distributions of deviations of the polarization plane from the direction tangential to the solar limb (angle χ) and the sign of χ are presented for Hα prominences of March 29, 2006. The obtained values of χ are in agreement with non-eclipse coronagraphic measurements and indicate the existence of longitudinal magnetic fields. The 2D distributions of the sign of χ 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.
