| Abstract: |
Our work had two objectives. First, we have extrapolated the 3D
coronal magnetic field lines from MDI magnetograms for three active
regions, in two different days for each one, and compared with
coronal images from XRT/Hinode or EIT/SOHO. Additionally,we computed
the force-free field parameter to estimate the twist in these active
regions where more explosive events occurred. |
