✦ Synopsis

Coronal electric currents are superposed on the calculated large-scale current-flee (potential) magnetic field of the solar corona and the new magnetic configurations are mapped. The results indicate that relatively large coronal electric currents are required before significant topological deviations from the potential magnetic field configuration cart be noticed. Thus any agreement between coronal observations and calculated potential magnetic field configurations should not be interpreted to mean that coronal electric currents are necessarily absent or insignificant.

Slow photospheric motions can produce flow speeds in the corona which are fast enough to violate quasi-static evolution. Therefore, high-speed flows observed in the corona are not necessarily due to a loss of equilibrium or stability. In this letter we present an example where the flow speed increas

A model of the large-scale magnetic field structure above the photosphere uses a Green's function solution to Maxwell's equations. Sources for the magnetic field are related to the observed photospheric field and to the field computed at a 'source' surface about 0.6 R G above the photosphere. The la

The high degree of symmetry often assumed in studies of the structure and stability of coronal magnetic field configurations is restrictive and can yield misleading results. We have therefore developed fully three-dimensional numerical methods for constructing force-free equilibria and for examining
