Comparing Methods for Calculating Solar Energetic Particle Intensities: Re-binning versus Spectral Binning
M. E. Cuesta, L. Y. Khoo, G. Livadiotis +13
Solar energetic particle (SEP) events have been observed for decades in the interplanetary medium by spacecraft measuring the intensity of energetic ions and electrons. These inten…
Observations of Kappa Distributions in Solar Energetic Protons and Derived Thermodynamic Properties
M. E. Cuesta, A. T. Cummings, G. Livadiotis +13
In this paper we model the high-energy tail of observed solar energetic proton energy distributions with a kappa distribution function. We employ a technique for deriving the therm…
Kappa-tail technique: Modeling and application to Solar Energetic Particles observed by Parker Solar Probe
G. Livadiotis, A. T. Cummings, M. E. Cuesta +10
We develop the kappa-tail fitting technique, which analyzes observations of power-law tails of distributions and energy-flux spectra and connects them to theoretical modeling of ka…
Parker Solar Probe Observations of Energetic Particles in the Flank of a Coronal Mass Ejection Close to the Sun
N. A. Schwadron, Stuart D. Bale, J. Bonnell +32
We present an event observed by Parker Solar Probe at 0.2 au on March 2, 2022 in which imaging and \emph{in situ} measurements coincide. During this event, PSP passed through…
Correlation of Coronal Mass Ejection Shock Temperature with Solar Energetic Particle Intensity
Manuel Enrique Cuesta, D. J. McComas, L. Y. Khoo +13
Solar energetic particle (SEP) events have been observed by the Parker Solar Probe (PSP) spacecraft since its launch in 2018. These events include sources from solar flares and cor…
Jovian electrons in the inner heliosphere: Opportunities for Multi-spacecraft Observations and Modeling
R. D. Strauss, N. Dresing, N. E. Engelbrecht +11
In this paper we explore the idea of using multi-spacecraft observations of Jovian electrons to measure the 3D distribution of these particles in the inner heliosphere. We present…
Particle Radiation Environment in the Heliosphere: Status, limitations and recommendations
Jingnan Guo, Bingbing Wang, Kathryn Whitman +14
Space weather is a multidisciplinary research area connecting scientists from across heliophysics domains seeking a coherent understanding of our space environment that can also se…
The modulation of anomalous and galactic cosmic ray oxygen over successive solar cycle minima
R. D. Strauss, R. A. Leske, J. S. Rankin
Both the recent 2009 and 2020 solar minima were classified as unusually quiet and characterized with unusually high galactic cosmic ray (GCR) levels. However, unlike the trends fro…
Galactic Cosmic Rays and Solar Energetic Particles in Cis-Lunar Space: Need for contextual energetic particle measurements at Earth and supporting distributed observations
Claudio Corti, Kathryn Whitman, Ravindra Desai +5
The particle and radiation environment in cis-lunar space is becoming increasingly important as more hardware and human assets occupy various orbits around the Earth and space expl…
Cosmic ray transport near the Sun
R. D. Strauss, J. P. van den Berg, J. S. Rankin
The strongly diverging magnetic field lines in the very inner heliosphere, through the associated magnetic focusing/mirroring forces, can, potentially, lead to highly anisotropic g…
PSP/ISIS Observation of a Solar Energetic Particle Event Associated With a Streamer Blowout Coronal Mass Ejection During Encounter 6
T. Getachew, D. J. McComas, C. J. Joyce +21
In this paper we examine a low-energy SEP event observed by ISIS's Energetic Particle Instrument-Low (EPI-Lo) inside 0.18 AU on September 30, 2020. This small SEP event has…
Observations of the 2019 April 4 Solar Energetic Particle Event at the Parker Solar Probe
R. A. Leske, E. R. Christian, C. M. S. Cohen +33
A solar energetic particle event was detected by the Integrated Science Investigation of the Sun (ISOIS) instrument suite on Parker Solar Probe (PSP) on 2019 April 4 when the space…
Seed Population Pre-Conditioning and Acceleration Observed by Parker Solar Probe
N. A. Schwadron, S. Bale, J. Bonnell +42
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…
Energetic Particle Observations from Parker Solar Probe using Combined Energy Spectra from the ISIS Instrument Suite
C. J. Joyce, D. J. McComas, E. R. Christian +18

The Parker Solar Probe was launched on 2018 August 12 and completed its second orbit on 2019 June 19 with perihelion of 35.7 solar radii. During this time, the Energetic particle I…
Galactic Cosmic-Ray Anisotropies: Voyager 1 in the Local Interstellar Medium
J. S. Rankin, E. C. Stone, A. C. Cummings +3
Since crossing the heliopause on August 25, 2012, Voyager 1 observed reductions in galactic cosmic ray count rates caused by a time-varying depletion of particles with pitch angles…
