Stokes inversions show the Evershed flow reverses to inflow in the upper photosphere while the moat flow remains an outflow, and umbral flashes exhibit supersonic upflows with Mach numbers at least 1.5 consistent with shock fronts.

Direct pixel-by-pixel comparison of 4-hour time series of Fe I 617.3 nm line-of-sight velocities from SO/PHI-HRT and SDO/HMI during Sun-Earth line crossing yields slope 0.96, 92% correlation, and formation-height difference of 7±14 km after alignment and large-scale velocity removal.
