Abstract :

We present the evolution of magnetic non potential parameter in AR 10930, during December 9-15, 2006. This AR highly active and produced a large number of flares with two X-class flare. We used 27 high-resolution vector magnetograms obtained with Hinode/SOT-SP. We studied the evolution of spatially averaged signed shear angle (SASSA) and mean weighted shear angle (MWSA) in the N-polarity and S-polarity regions separately. We found the SASSA is same for both polarities. In S-polarity, the MWSA is high compare to N-polarity. SASSA and MWSA show similar trends during the observed period.
