Summary of PFSS models that were fit to the interplanetary magnetic field polarity and scattered white light observations. Coloured markers show the in situ measurements from PSP, Solar Orbiter, and Wind during two weeks around each encounter. The grey scale shows the scattered white light brightness from SOHO/LASCO-C2 at three solar radii. The red and blue background colour shows the polarity predicted by the PFSS model, with the source surface radius and ADAPT-GONG map date annotated.
