We present a new 3D magnetohydrostatic (MHS) direct elliptic solver for extrapolating the coronal magnetic field from photospheric boundary conditions in a manner consistent with an assumed plasma distribution.

During the upcoming 4th Parker Solar Probe (PSP) perihelion on January 29 2020, the Earth and many space observatories will be near-radially aligned with PSP and STEREO-A will be near quadrature (at a rig

The magnetic field in the corona is important for understanding solar activity. Linear polarization measurements inforbidden lines in the visible/IR provide information about coronal magnetic direction and topology.
