Narrow lanes of transverse magnetic field in sunspots
Article Abstract:
The examination of a solar sunspot group revealed the presence of oppositely-directed vertical-field inversions spaced by narrow channels of strong horizontal fields. The vertical fields curved across the inversion line in a low-energy arrangement, while new energy spots moving through old magnetic-fields resulted in the field lines turning along the inversion line and getting connected with the vertical field. These varied channels indicate substantial electric current, and all the flares in these regions occur in these intricate fields.

The dark side of the sun
Article Abstract:
The Sun's 11-year cycle is driven by its magnetic field and generates a flow of charged particles known as the solar wind, which explode as huge solar flares above the dark patches on the Sun causing turbulence in the solar wind and sending streams of charged particles hurtling through space. In late October 2003, three year after the cycles peak, two monstrous sunspots appeared, each more than ten times the diameter of Earth and both in a state of almost eruption, spewing out billions of tonnes of electricity charged particles.

Magnetic geometry of sunspots
Article Abstract:
Successful resolution of the fine structures of sunspots show why these structures have been difficult to model. White-light photographs of sunspots show the different directions of their magnetic field in bright and dark filaments which greatly affect their structures. These new observations can explain inconsistencies in the measurements of field line inclinations. Other questions raised on the the structure of sunspots and starspots can be answered by helioseismological techniques.
