Time sequences overview of magnetic and plasma measurements during PSP’s first encounter. Panel (a): magnetic field strength (﹩| B| ﹩) and proton density (N_p). Panels (b), (c), and (d): magnetic fields (﹩{B}_{{\rm{R}}},{B}_{{\rm{T}}},{B}_{{\rm{N}}}﹩) and proton bulk velocities (﹩{V}_{{\rm{R}},{\rm{p}}},{V}_{{\rm{T}},{\rm{p}}},{V}_{{\rm{N}},{\rm{p}}}﹩) in RTN coordinates. Panel (e): proton density (N_p) and thermal velocity (W_p). Panel (f): plasma beta (β) and heliocentric distance (R) of spacecraft’s position.
