The Solar Orbiter (SolO) Polarimetric and Helioseismic Imager (PHI) is now providing the first-ever photospheric magnetograph observations taken from off of the Sun-Earth line. These alternate perspectives are particularly valuable for the creation of global solar magnetic maps that are commonly used as the inner boundary condition for coronal, solar wind, and heliospheric models. We present preliminary results from the integration of the first three years of SolO/PHI Full Disc Telescope (FDT) observations into the Air Force Data Assimilative Photospheric flux Transport (ADAPT) model. We investigate periods when SolO observed flux evolution on the far-side of the Sun and compare Wang-Sheeley-Arge (WSA) coronal and solar wind models with and without this evolution. Finally, we comment on the future prospects for regular inclusion of PHI/FDT data in ADAPT data products, particularly in light of SolO’s eventual high-latitude orbit. The ADAPT model development is supported by AFRL.
