Top row: Maps of the continuum intensity (left) and of the Hα line core intensity (right) of AR 11339 on 6 November 2011 obtained by Hinode/SOT-FG. The red contour highlights the position of an OPU. The horizontal line indicates a length of 20″ and the arrow points towards disk centre. The AR was located at a heliocentric angle μ = 0.89. Botton row: Panels displayed from left to right show the maps of the OPU of the continuum, magnetic field strength, inclination and azimuth (black lines), and LOS velocity.
