Unusual composition in a solar energetic particle event observed near the Sun
Abstract
The EPI-Lo instrument is part of the Integrated Science Investigations of the Sun (IS0IS) suite on Parker Solar Probe. On 2020 DOY 272 (Orbit 6), the EPI-Lo instrument observed a solar energetic particle (SEP) event with a very unusual composition. This event was observed at about 0.1 au, just after perihelion and had no significant increase in particles at EPI-Hi energies. The observations from EPI-Lo and other instruments will be discussed, as well as possible explanations for the unusual composition.
