3D HD resolution animation showing 1)Results from a three dimensional computation of the magnetic field structure of an active region extrapolating the fields from measurements of the magnetic field on the surface of the Sun. This model assumes there are no electrical currents in the corona, leading to a very simple magnetic configuration. From Tahar Amari, Centre de Physique Theorique, Ecole Polytechnique, Paris. 2)Results from a three dimensional computation of the magnetic field structure of an active region extrapolating the fields from measurements of the magnetic field on the surface of the Sun. This model allows currents to flow and assumes force balance, leading to a more complex magnetic configuration for the same surface magnetic fields. From Tahar Amari. 3)Results from a three dimensional computation of the magnetic field structure of the corona extrapolating the fields from measurements of the magnetic field on the surface of the Sun. This models the corona for February 2007. Model from Pete Riley, SAIC, San Diego.
