Slow wind belt in the quiet solar corona

The slow solar wind belt in the quiet corona, observed with Metis coronagraph on board Solar Orbiter May 15, 2020, during activity minimum of cycle 24, a field view extending from 3.8 $R_\odot$ to 7.0 $R_\odot$, is formed by and dense stream running along coronal current sheet, accelerating radial direction reaching at 6.8 speed within 150 km s$^{-1}$ 190 s$^{-1}$, depending assumptions velocity distribution neutral hydrogen atoms plasma. separated thin regions high shear faster streams, almost symmetric relative peak 175 230 same level. density-velocity structure zone discussed terms expansion factor open magnetic lines that known be related quasi-steady wind, relation presence web quasi separatrix layers, S-web, potential sites reconnection release plasma into wind. parameters characterizing are derived 3D MHD model calculations. S-web found coincide latitudinal region where outer corona surrounded layers expanding non-monotonic way.
