Sa. Kazantsev et al., SPECTROPOLARIMETRIC STUDIES OF H-ALPHA EMISSION IN SOLAR MOUSTACHES -OBSERVATIONS AND CALCULATION OF THE STOKES PARAMETERS, Astronomy reports, 42(5), 1998, pp. 702-706
The results of spectropolarimetric observations of three solar ''moust
aches'' carried out on the Large Vacuum Solar Telescope of Baikal Obse
rvatory of the Institute of Solar-Terrestrial Physics are presented. T
he observed degree of polarization varies from 2-13%. The direction of
the plane of polarization for a moustache with moderate intensity is
tangential, and is radial for the weakest moustache. In the brightest
moustache, the plane of polarization is close to radial at the line ce
nter, and is tangential in the wings.
