A series of solar energetic particle (SEP) events were observed at Parker
Solar Probe (PSP) by the Integrated Science Investigation of the Sun (\ISOIS)
during the period from April 18, 2019 through April 24, 2019. The PSP
spacecraft was located near 0.48 au from the Sun on Parker spiral field lines
that projected out to 1 au within $\sim 25^\circ$ of near Earth spacecraft.
These SEP events, though small compared to historically large SEP events, were
amongst the largest observed thus far in the PSP mission and provide critical
information about the space environment inside 1 au during SEP events. During
this period the Sun released multiple coronal mass ejections (CMEs). One of
these CMEs observed was initiated on April 20, 2019 at 01:25 UTC, and the
interplanetary CME (ICME) propagated out and passed over the PSP spacecraft.
Observations by the Electromagnetic Fields Investigation (FIELDS) show that the
magnetic field structure was mostly radial throughout the passage of the
compression region and the plasma that followed, indicating that PSP did not
directly observe a flux rope internal to the ICME, consistent with the location
of PSP on the ICME flank. Analysis using relativistic electrons observed near
Earth by the Electron, Proton and Alpha Monitor (EPAM) on the Advanced
Composition Explorer (ACE) demonstrates the presence of electron seed
populations (40--300 keV) during the events observed. The energy spectrum of
the \ISOIS~ observed proton seed population below 1 MeV is close to the limit
of possible stationary state plasma distributions out of equilibrium. \ISOIS~
observations reveal the \revise{enhancement} of seed populations during the
passage of the ICME, which \revise{likely indicates a key part} of the
pre-acceleration process that occurs close to the Sun.
