Temporal profiles of solar wind parameters from 28 February to 15 March 2017 (59–74 doy), at a time resolution of 6 s. The panels show the proton velocity components in the HEE reference system, V_x (panel a), V_y (panel b), and V_z (panel c), the proton number density (panel d) and proton temperature (panel e), the magnetic field magnitude (panel f) and magnetic field components in HEE, B_x (panel g), B_y (panel h), and B_z (panel i), and the angle θ = cos⁻¹(|B_x|/|B|) between the average magnetic field direction and the radial direction (panel j). In the last panel, the dashed black curve represents the local Parker spiral direction with respect to the high-speed region and rarefaction region.
