The Solar Orbiter (SO) Polarimetric and Helioseismic Imager (PHI) is now providing the first-ever photospheric magnetograms taken from off of the Sun-Earth line. At times, when combined with Global Oscillations Network Group (GONG) or Helioseismic and Magnetic Imager (HMI) observations, this doubles the visible solar surface and enables instantaneous measurement of significantly more of the Sun’s photospheric magnetic field. We present a new near-real-time data product incorporating SO/PHI Full Disc Telescope (FDT) Low Latency observations into ADAPT (Air Force Data Assimilative Photospheric flux Transport) magnetic maps. These maps are designed to drive other near-real-time space weather nowcast and forecast models, as well as facilitate coordination of multi-instrument observational campaigns. We discuss the limitations of these data products compared with FDT science quality data and consider their value in the future when SO/PHI/FDT will better observe the solar poles. The ADAPT model development is supported by AFRL.
