A new source alignment technique applied to PSP and SO data reveals the solar wind speed increases by an average of 45% per radial decade between the spacecraft, indicating ongoing acceleration beyond 15 solar radii.
TMF simulation of AR 12975 reproduces filament channel formation and energy/helicity injection but shows eruption helicity ratio of 0.23 and torus instability at 0.32 due to complex field configuration.
