Large gradual solar energetic particle events

open access: yesLiving Reviews in Solar Physics, 2016
Solar energetic particles, or SEPs, from suprathermal (few keV) up to relativistic ( ∼ few GeV) energies are accelerated near the Sun in at least two ways: (1) by magnetic reconnection-driven processes during solar flares resulting in impulsive SEPs, and (2) at fast coronal-mass-ejection-driven shock waves that produce large gradual SEP events.

Transmission and Emission of Solar Energetic Particles in Semi-transparent Shocks. [PDF]

open access: yes, 2014
While major solar energetic particle (SEP) events are associated with coronal mass ejection (CME)-driven shocks in solar wind, accurate SEP measurements reveal that more than one component of energetic ions exist in the beginning of the events.

GCR access to the Moon as measured by the CRaTER instrument on LRO [PDF]

open access: yes, 2010
[1] Recent modeling efforts have yielded varying and conflicting results regarding the possibility that Earth\u27s magnetosphere is able to shield energetic particles of \u3e10 MeV at lunar distances.

Energetic charged particles near Europa [PDF]

open access: yesJournal of Geophysical Research: Space Physics, 2000
Galileo energetic particles detector (EPD) data are presented from several close encounters of the spacecraft with Jupiter's moon Europa. These data reveal significant decreases in electron and ion count rates very close to the moon and a few Europa radii downstream. The relation between count rate decreases and satellite absorption is analyzed because

Solar flares and energetic particles [PDF]

open access: yesPhilosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2012
Solar flares are now observed at all wavelengths from γ -rays to decametre radio waves. They are commonly associated with efficient production of energetic particles at all energies. These particles play a major role in the active Sun because they contain a large amount of the energy released during flares ...

From the Sun’s south to the north pole – Ulysses COSPIN/LET composition measurements at solar maximum [PDF]

open access: yesAnnales Geophysicae, 2003
Based on elemental abundance ratios derived from the Ulysses COSPIN/LET measurements, we classified the energetic particle populations during and after the socalled Fast Latitude Scan – the time period during which the Ulysses spacecraft traveled

Energetic Charged Particles Above Thunderclouds [PDF]

open access: yesSurveys in Geophysics, 2012
The French government has committed to launch the satellite TARANIS to study transient coupling processes between the Earth’s atmosphere and near-Earth space. The prime objective of TARANIS is to detect energetic charged particles and hard radiation emanating from thunderclouds. The British Nobel prize winner C.T.R.

Energetic particle observations at the subsolar magnetopause [PDF]

open access: yesAnnales Geophysicae, 2002
The pitch-angle distributions (PAD) of energetic particles are examined as the ISEE-1 satellite crosses the Earth’s magnetopause near the subsolar point.
