Using instruments on the ACE and Wind spacecraft, we investigate the temporal
evolution, spectrum, and ionization states of Solar Energetic Particle (SEP) Fe in
the impulsive event of 2000 May 1. Proton and electron intensities and anisotropies
were used to help constrain the characteristics of the interplanetary propagation
taking account of focusing, pitch-angle scattering, adiabatic decele

Fluxes of protons at the energies 0.8 - 4 GeV accelerated during solar flares of
October-November 2003 were detected onboard the CORONAS-F satellite (polar
circular orbit with an altitude ~450 km). The SONG instrument had sufficient
geometric factor (~1500 cm2∙sr) to detect directly solar protons as a count rate
exceeding above a background level when the satellite crossed a wide range o

We survey the properties (including the abundance variations) of the >20 MeV
proton events (~300) that occurred in the years 1997-2005 inclusive. About
20% of the events have the properties of so-called "impulsive events" that are
considered to arise from acceleration in flares. We compare the properties and
associated flare phenomena of these events with those of the larger events
that

In association with the large solar flare of April 15th 2001, the Chacaltaya
neutron monitor observed an 8.2 sigma enhancement of the counting rate
between 13:51 and 14:24 UT. Since the enhancement was observed from 11
minutes before the GLE, solar neutrons must be involved in this enhancement.
Comparing with the Yohkoh Soft X-ray Telescope images with the observed
particle time profi

Measurements with advanced instrumentation on the SAMPEX, SOHO and ACE spacecraft show a large
variability of the ionic charge of heavy ions in solar energetic particle (SEP) events with energy,
in particular for Fe. In this paper we present a survey of ionic charge observations in interplanetary shock
related SEP events obtained in the energy range ~0.18-0.43 MeV/nuc with the SEPICA instrum

We consider the production of light isotopes due to nuclear interactions and
acceleration in flare regions. The Monte-Carlo method allows us to take into
account several steps of particle interactions with ambient plasma. In our
model high abundance ratios of He3/He4 are obtained at certain simulation
parameters. Subsequent interplanetary propagation effects could result in the
energy sp

Numerous discrete, small, impulsive solar energetic particle (ISEP)
events with measurable intensities of 3He at energies above 5
MeV/nucleon are observed around the solar maximum of the 11-year solar
cycle. In addition, at times when there are no clearly
distinguishable ISEP events it is common to observe a low,
quasi-steady intensity of 3He at these energies. Recent measurements
under so
