Abstract:
In the early hours of June 13, 2020, just after the end of its 5th solar encounter, the Faraday Cup on-board Parker Solar Probe (PSP) registered the passage of a prominent solar wind structure embedded in highly variable plasma and characterized by regions with distinct plasma conditions (speed, density, magnetic field, etc) and wave activity. From remote sensing observations, using spacecraft at different heliospheric locations, several transients were observed ejected from the Sun, including a coronal mass ejection (CME) oriented away from PSP that may have also influenced the solar wind conditions through which the structure in question has propagated. In this work, we report the PSP-SPC observations around this structure and identify possible solar sources relying on multi-spacecraft observations. We also characterized the propagation and evolution of the CME observed on June 12, 2020 and the role it played influencing the conditions of the unusual variable ambient solar wind.
