The solar wind speed gradually decreases with increasing distance from the Sun and becomes clear at about 30 au and ranges from 13% to 15% between 50.0 and 58.42 au. In the top panel we show a time series of the percent difference in the propagated solar rotation–averaged 1 au speeds in the inner heliosphere and NH in the outer heliosphere as a function of distance between NH and the Sun.
