During Encounter 19, Parker Solar Probe (Parker) achieved several unique observational alignments with the Earth and Solar Orbiter (SolO) in the run-up to the solar eclipse. Significantly, it crossed the same solar wind stream as SolO and Wind, allowing for coordinated observations across missions. Using observations from these three spacecraft, this study investigates the spatiotemporal evolution of solar wind streams in the vicinity of the heliospheric current sheet sampled during five crossings at different distances in the  inner heliosphere. Dynamic time warping (DTW) is used to map traversal time series using the current sheet crossings as alignment markers, in order to understand the temporal and spatial evolution of the solar wind.
