The Analysis of Magnetic Field Vector in AR 11263 Based on SDO Data
Abstract
Configuration changes of complex magnetic field could trigger flares. Using magnetic field data obtained from SDO-HMI we analyzed the dynamics of magnetic field configuration in active regions. We tried to employ the idea of Moore et al. (2012) that the direction of magnetic field lines which aligned themselves to the neutral line could trigger flare. Using the VAPOR software, we analyzed the magnetic field changes in AR 11263 before the flare explosions, especially changes in direction and the value of the magnetic field. The results of our investigation is that there were some changes of magnetic flux direction in which the closer the time of explosion, the smaller the angle subtended by the flux with the plane of reference of the neutral line. Keywords: flares - magnetic field change - neutral lines - deviation of tangential components
