The SONG instrument onboard the CORONAS-F satellite detected solar flare
gamma-ray emission in the energy range 50 keV – 300 MeV. Study of the fluxes
and spectra obtained during several major flares shows presence of the
gamma-ray emission at the energy > 40 MeV with the characteristic spectrum
feature generated by neutral pion decay. This feature proves unambiguously
that protons wer

In early December 2006, a large active region (number 10930) rotated over the eastern
limb of the Sun. As it crossed the disk, it generated 4 X-class flares and at least
3 halo coronal mass ejections. Two large SEP events were generated when the region
was at ~E70 and ~W25 and were observed by several spacecraft, including ACE and
STEREO. We have combined observations from the Solar Isotope

The twin STEREO spacecraft each include four solar energetic particle (SEP) sensors
(part of the IMPACT investigation) that measure the composition and energy spectra of
SEP ions with 1 ≤ Z ≤ 28 from ~0.05 to ~100 MeV/nuc, as well as electrons. One of
these is the Low Energy Telescope (LET), which measures SEP composition from ~3 to
~30 MeV/nuc. The LET sensors were first powered up in spa

It has been shown in a series of works that some solar particle events (SPE)
are composed of two different relativistic populations, a Prompt Component
(PC) and a Delayed Component (DC), each one with different energy spectrum
behavior. The source spectra of the DC tend to be an inverse power law at the
steady state situation, whereas the spectra of the PC are considerable
deviated

A new generation of instruments during solar cycle 23 made it possible to measure
solar energetic particle (SEP) energy spectra for many species over a broad energy
interval (~0.1 to ~100 MeV/nuc). These observations revealed that most large SEP
events have power-law spectra below a few MeV/nuc with rather hard spectral indices,
followed by spectral breaks at higher energies. The spectral brea

We describe the High Energy Telescopes (HETs), which are part of the IMPACT
investigation for the STEREO mission (Principal Investigator: Janet Luhmann,
University of California at Berkeley). The two STEREO spacecraft were launched from
Cape Canaveral, FL on October 25, 2006. High energy electrons (~ 0.7 -6 MeV) and
nuclei from hydrogen to iron (~ 13 – 200 MeV/nucleon) are detected by the
