PSP/IS⊙IS observations of the onset of the energetic electron (left) and proton enhancement (right). Top left: Time profile of ∼920 keV electrons observed by the three orthogonal EPI-Hi/LET telescope apertures. Left second panel: Pitch angle of each of the EPI-Hi/LET apertures. Left middle: Time profile of ∼90 keV electrons observed by EPI-Lo wedges 3 and 7 (sunward and anti-sunward facing, respectively). Left fourth panel: Pitch angle of the boresight of EPI-Lo wedges 3 and 7. Left bottom: Magnetic field magnitude and vector in RTN coordinates as measured by the PSP/FIELDS magnetometer. Top right: Time profile of ∼10 MeV protons observed by the three orthogonal EPI-Hi/LET telescope apertures. Right middle: time profile of ∼25 MeV protons observed by the three orthogonal EPI-Hi/LET telescope apertures. Right bottom: Pitch angle of each of the EPI-Hi/LET apertures.
