PSP crossing CME #2 downstream region. In the panels on the left half, from top to bottom: (a) magnetic field intensity normalized by the square of the solar distance, (b)–(d) its radial, tangential, and normal components (one panel for each), (e) solar wind proton bulk speed, (f) electron density (also normally by the square of the distance), (g) the proton temperature (h), plasma beta parameter, (i) Alfvénic Mach number, and (j) the electron pitch angle distribution. Clear signatures of this region include low plasma beta and an increase in the magnetic field (periods A–B and C–D). Panels (k), (l), and (m) correspond to the times “A,” “F,” and “G” indicated by the red vertical lines over panels (a)–(j). The plane shown corresponds to the solar equator, and the Sun is located in its center.
