AB: In this talk we briefly review current theories of the large-scale heliospheric magnetic field. We address how measurements of the coronal magnetic field can be connected to in situ observations through numerical models, and likewise, how in situ observations can be connected back to both solar observations and model results. We focus on deviations from the ideal Parker spiral (e.g., radial field lines, under-winding, over-winding, magnetic flux variations, transient phenomena, etc) from near-Earth spacecraft as well as Ulysses, and ask to what extent these observations can place constraints on theories of the structure and evolution of the coronal magnetic field.
