Title:  The Magnetic Corona and the Promise of Coronagraphic Magnetometry  

Abstract:  The Sun's outer atmosphere is not only hot but also acts as a reservoir of magnetic energy awaiting release during flares and Coronal Mass Ejections (CMEs).  Its existence and evolution is governed by its magnetic field and its ties to magnetoconvection, which for decades we have tried to better understand through sparse measurements.  The lack of magnetic field inferences in the corona is widely recognized as a difficult obstacle.  With the National Science Foundation's Daniel K Inouye Solar Telescope (DKIST), we are now entering into a new era, as we advance capabilities that directly address these difficulties through novel polarimetric observations in the off-limb corona.  In this talk, I will discuss polarimetry of both the hot and cool corona from an observational and theoretical perspective, to address both the challenges and great promise of coronagraphic magnetometry, further discussing how these observables may be used in the near future to better understand the coronal magnetic field.
