High-energy particles were recorded by near-Earth spacecraft and ground-based neutron monitors (NMs) on 2012 May 17. This event was the first ground level enhancement (GLE) of solar cycle 24. In this study, we try to identify acceleration source(s) energetic combining in situ particle measurements from WIND/3DP, GOES 13, cosmic rays registered several NMs, as well remote-sensing observations SDO/AIA, SOHO/LASCO, RHESSI. We derive interplanetary magnetic field (IMF) path length (1.25 ± 0.05...
28 February 2017 marked 75 years since the first confident registration of solar cosmic rays (SCRs), i.e., accelerated particles with energies from about 10 6 to ~10 ÷ 11 eV. Modern state problems related studies Ground Level Enhancements (GLEs) relativistic SCRs is critically analyzed based on available direct and proxy data. We are also taking into account extremely large fluxes non-relativistic energetic (SEPs). Both kinds SCR events great astrophysical geo-scientific (geophysical)...
This review paper comprises main concepts, available observational data and recent theoretical results related to astrophysical aspects of particle acceleration at/near the Sun extreme capacities solar accelerator(s). We summarize underground ground-based observations cosmic rays (SCR) accumulated since 1942, direct spacecraft measurements energetic particles (SEP) near Earth's orbit, indirect information on SCR variations in past, other relevant astrophysical, geophysical data. The list...
In this work, plastic scintillators based on mixed polystyrene-polyphenylmethylsiloxane have been created, and their mechanical scintillation characteristics studied. The created polystyrene containing 30 wt. % polyphenylmethylsiloxane, demonstrated radiation resistance reaching 22 Mrad. obtained PSs retain physical properties at a level that ensures ease of processing the material makes it possible to obtain samples in wide range shapes sizes.
In this study, all available data on the largest solar proton events (SPEs), or extreme energetic particle (SEP) events, for period from 1561 up to now are analyzed. Under consideration observational, methodological and physical problems of energy-spectrum presentation SEP fluxes (fluences) near Earth's orbit. Special attention is paid study distribution function fluences SEPs by their sizes. The authors present advances in at least three aspects: 1) a form that was previously obtained...
A flare on 2003 October 28 produced a relativistic particle event at Earth, although the active region AR 10486 was located to east of central meridian Sun. The paper considers features related acceleration Sun and propagation Earth energetic particles in this event, which occurred disturbed interplanetary background caused by preceding activity corotating high‐speed solar wind stream. From study onset times different neutron monitors, we conclude that earliest arriving were neutrons. first...
Abstract The 28th of February 2017 marked the 75th anniversary first confident detection solar cosmic rays (SCRs), a term referring to accelerated particles with energies from about 10 6 ∼ − 11 eV. present paper reviews key observational and theoretical results on SCRs that have been accumulated over this period. history discovery is briefly described, together SCR recording techniques instruments, some physical, methodical, practical aspects generation are discussed in more detail. Special...

Using the data from neutron monitors and applying various techniques, parameters of relativistic solar protons (RSPs) outside magnetosphere are currently being derived by several research groups. Such data, together with direct proton measurements balloons spacecraft, allow determination particle energy spectra near Earth's orbit in successive moments time. Spectra RSPs a number large events tend to indicate existence multistep acceleration at/near Sun. In this paper, we study generation RSP...
