Measurements of Photospheric Magnetic Flux and Magnetic Field Models
Session ID#: 81390
Session Description:
Photospheric magnetic flux measurements are extremely important for modeling of coronal magnetic fields. However, the use of photospheric magnetic flux measurements poses a number of challenges. Magnetograms from different observatories exhibit differences that can be challenging to reconcile, there is currently no source of magnetic measurements from the far side of the sun, and polar/limb fluxes are poorly measured. In this session we welcome submissions related to measuring the photospheric magnetic field, comparing and/or combining different measurements, and pre-conditioning photospheric flux measurements for use in coronal magnetic field models.
