Integrating SolO/PHI farside magnetograms into global solar magnetic maps

The Solar Orbiter (SolO) Polarimetric and Helioseismic Imager (PHI) is now providing the first-ever photospheric magnetogram 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 the preliminary integration of SolO/PHI Full Disc Telescope (FDT) observations into the Air Force Data Assimilative Photospheric flux Transport (ADAPT) model. This investigation focuses on a period when SolO observes flux emergence on the “farside” of the Sun and we compare Wang-Sheeley-Arge (WSA) coronal and solar wind models with and without this emergence. Finally, we comment on the future prospects for regular inclusion of PHI/FDT data in real-time ADAPT products, particularly in light of SolO’s eventual high-latitude orbit. This work utilizes data produced collaboratively between the Air Force Research Laboratory (AFRL) and the National Solar Observatory. The ADAPT model development is supported by AFRL.
