Buildup and Release of Magnetic Twist during the X3.4 Solar Flare of December 13, 2006
ASTROPHYSICAL JOURNAL, pp. 172012.
We analyze the temporal evolution of the three-dimensional magnetic structure of the flaring active region (AR) NOAA 10930 by using the nonlinear force-free fields extrapolated from the photospheric vector magnetic fields observed by the Solar Optical Telescope on board Hinode. This AR consisted mainly of two types of twisted magnetic fie...More
