Near limb 180-ambiguity resolution and NLFF extrapolation of vector magnetogram of AR 10930
Smoothed magnetograms of the magnetic field transverse component (Hinode SOT/SP level2 17 December 2006 0:25:28 UT) after resolving azimuth ambiguity by our algorithm. By By (left), Bz (right). Z axis directed upward. Y axis directed from left to right.
Field lines of the potential (left) and nonlinear force-free (right) fields. At the bottom is the X-ray image from Hinode XRT (17 December 2006 0:24:20.5 UT) with changed contrast. Contour lines are distribution of the calculated normal field component; limb line – yellow.
