Abstract Solar Energetic Particle (SEP) events are interesting from a scientific perspective as
they are the product of a broad set of physical processes from the corona out through the …

A new catalogue of 314 solar energetic particle (SEP) events extending over a large time
span from 1984 to 2013 has been compiled. The properties as well as the associations of …

Solar energetic particles (SEPs) constitute an important component of the radiation
environment in interplanetary space. Accurate modeling of SEP events is crucial for the …

An interval of exceptional solar activity was registered in early September 2017, late in the
decay phase of solar cycle 24, involving the complex Active Region 12673 as it rotated …

The Solar Accumulated and Peak Proton and Heavy Ion Radiation Environment
(SAPPHIRE) model provides environment specification outputs for all aspects of the Solar …

The backside coronal mass ejection (CME) of 2012 July 23 had a short Sun-to-Earth shock
transit time (18.5 hr). The associated solar energetic particle (SEP) event had a> 10 MeV …

New recently installed high-altitude polar neutron monitors (NMs) have made the worldwide
NM network more sensitive to strong solar energetic particle (SEP) events, registered at …

Little is known about the origin of the high-energy and sustained emission from solar long-
duration gamma-ray flares (LDGRFs) identified with the Compton Gamma Ray Observatory …

Large solar eruptive events, including solar flares and coronal mass ejections (CMEs), can
lead to solar energetic particle (SEP) events. During these events, protons are accelerated …

Abstract Space radiation affects every aspect of spacecraft design and operation. As a part
