The line-of-sight magnetograms from Solar Optical Telescope Narrowband Filter Imager observations of NOAA Active Region 10930 have been used to study the evolution of spinning and braiding helicities over a period of five days starting from 2006 December 9. The north (N) polarity sunspot was the follower and the south (S) polarity sunspot was the leader. The N-polarity sunspot in the active region was rotating in the counterclockwise direction. The rate of rotation was small during the first… Expand

Sunspot Rotation, Sigmoidal Filament, Flare, and Coronal Mass Ejection: The Event on 2000 February 10
We find that a sunspot with positive polarity had an obvious counterclockwise rotation and resulted in the formation and eruption of an inverse S-shaped filament in NOAA Active Region 08858 from 2000Expand
Buildup and Release of Magnetic Twist during the X3.4 Solar Flare of 2006 December 13
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 photosphericExpand
Distribution of Magnetic Helicity Flux with Solar Cycles
It is normally believed that a magnetic field transfers helicity from the solar subatmosphere into interplanetary space. This is based on the calculation of the injected magnetic helicity near theExpand

Search for a Signature of Twist-removal in the Magnetic Field of Sunspots in Relation with Major Flares
We investigate the restructuring of the magnetic field in sunspots associated with two flares: the X6.5 flare on 6 December 2006 and the X2.2 flare on 15 February 2011. The observed changes wereExpand
On the line profile changes observed during the X2.2 class flare in the active region NOAA 11158
The solar active region NOAA 11158 produced a series of flares during its passage through the solar disk. The first major flare (of class X2.2) of the current solar cycle occurred in this activeExpand
A Semi-Automatic Method to Measure the Rotation of Sunspots
Sunspots have been observed to undergo rotation about their umbral centre. This is typically a slow rotation, with even the fastest sunspot rotations only reaching angular velocities of a few degreesExpand
Magnetic clouds along the solar cycle: expansion and magnetic helicity
Abstract Magnetic clouds (MCs) are objects of extreme importance in the heliosphere. They have a major role on releasing magnetic helicity from the Sun (with crucial consequences on the solarExpand
