Abstract: With the first years of SO/PHI data now available, it is routinely possible to observe the Sun simultaneously from multiple vantage points away from the Earth–Sun line. This enables joint observational campaigns with similar instruments, such as the Helioseismic and Magnetic Imager (HMI) aboard the Solar Dynamics Observatory (SDO). We use this opportunity to generate combined magnetic synoptic maps from line-of-sight magnetograms of the SO/PHI Full Disk Telescope (FDT) and SDO/HMI. Building on the existing HMI synoptic map framework, we extend its functionality to incorporate SO/PHI-FDT data and to account for the differing orbital and observational characteristics of the two spacecraft. The resulting joint maps can be produced much faster than the ≈27 days of one solar rotation, reducing the impact of magnetic field evolution. We present the first set of combined synoptic maps created using science-quality SO/PHI-FDT data from the 2024–2025 synoptic campaigns. After outlining the current pipeline capabilities, we show examples from different phases of the SO/PHI orbit, compare them with their SDO/HMI counterparts, and examine how the different state of the solar magnetic field influences coronal extrapolations based on these maps. Finally, we discuss the roadmap toward public release and planned future developments.
