| Abstract: |
Results from broad-band filter, high-precision, linear polarimetry
in Hα–prominences taken on March 29, 2006 are presented. The
contrast between the prominence and the corona is estimated. Comparison of 2D
distributions of the degree of polarization based on 3 orientations of a
polarizer and on 24 orientations reveals the systematic decreasing of
≈ 2% in the polarization degree for the noisier
signal. Measured polarization degrees of 1–7% in the height
range of 30–90″ are below the theoretical curve
for pure resonance scattering. The promise of the method for
synoptical observations in 2 lines are noted. |
