Time profiles of the solar wind bulk speed (top panel) and density (bottom panel), from Solar Orbiter/RPW (blue) and Wind (red) observations. Wind data are time-shifted by +1.7 days and (for the plasma density) scaled back to the Solar Orbiter position (to take into account the different longitude and distance of Solar Orbiter with respect to Wind). RPW density estimates are not available before June 6, 2020.
