Characteristics of Sustained >100 MeV Gamma-ray Emission Associated with Solar Flares
G. H. Share, R. J. Murphy, A. K. Tolbert +4
We characterize and provide a catalog of thirty >100 MeV sustained gamma-ray emission (SGRE) events observed by Fermi LAT. These events are temporally and spectrally distinct from…
Why is solar cycle 24 an inefficient producer of high-energy particle events?
Rami Vainio, Osku Raukunen, Allan J. Tylka +2
The aim of the study is to investigate the reason for the low productivity of high-energy SEPs in the present solar cycle. We employ scaling laws derived from diffusive shock accel…
Deriving the properties of coronal pressure fronts in 3-D: application to the 17 May 2012 ground level enhancement
Alexis P. Rouillard, Illya Plotnikov, Rui F. Pinto +12
We study the link between an expanding coronal shock and the energetic particles measured near Earth during the Ground Level Enhancement (GLE) of 17 May 2012. We developed a new te…
Comment on "Detection and characterization of 0.5-8 MeV neutrons near Mercury: Evidence for a solar origin"
Gerald Share, Ronald Murphy, Allan Tylka +2
We argue that the hour-long neutron transient detected by the MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MESSENGER) Neutron Spectrometer beginning at 15:45 UT o…
On the Remote Detection of Suprathermal Ions in the Solar Corona and their Role as Seeds for Solar Energetic Particle Production
J. Martin Laming, J. Dan Moses, Yuan-Kuen Ko +3
Forecasting large Solar Energetic Particle (SEP) events associated with shocks driven by fast coronal mass ejections (CME) pose a major difficulty in the field of Space Weather. Be…
Physics of Solar Neutron Production: Questionable Detection of Neutrons from the 2007 December 31 Flare
Gerald H. Share, Ronald J. Murphy, Allan J. Tylka +3
Spacecraft observations in the inner heliosphere offer the first opportunity to measure 1-10 MeV solar neutrons. We discuss the physics of low-energy neutron production in solar fl…
