Variations of the 3-D coronal magnetic field associated with the X3.4-class solar flare event of AR 10930

Chen, P. F.; Yan, Yihua; Wang, Huaning +2 more

The variations of the 3-D coronal magnetic fields associated with the X3.4-class flare of active region 10930 are studied in this paper. The coronal magnetic field data are reconstructed from the photospheric vector magnetograms obtained by the Hinode satellite and using the nonlinear force-free field extrapolation method developed in our previous…
