Detailed observations for the ∼2.2-minute interval highlighted in Fig. 2. (a) Magnetic field components in RTN coordinates. (b) Magnetic field components in the local current sheet coordinate system (X, Y, Z). (c) Magnitude of the solar wind bulk velocity |V| and its radial component V_R in RTN coordinates. (d) V_X in the current sheet coordinates. (e) Tangential and normal velocity components, V_T and V_N, in RTN. (f) V_Y and V_Z in the current sheet coordinates. (g) Proton number density. (h) Parallel and perpendicular components of the proton temperature (T_∥ and T_⊥). (i) Schematic illustration of magnetic reconnection at the HCS, showing magnetic flux ropes (FRs) embedded within the reconnection exhaust region, the local current sheet coordinate system (X, Y, Z), and PSP passage (green). (j) Average suprathermal electron flux (433 eV) vs. pitch angle during each of the four events (highlighted in yellow).
