It turned out to be really a rare and happy occasion to know exactly when and how a new
branch of space physics was born, namely, a physics of solar cosmic rays. It happened on …

Solar energetic particles (SEPs) constitute an important component of the radiation
environment in interplanetary space. Accurate modeling of SEP events is crucial for the …

Aims. Long-term fluxes or integral fluences of solar energetic particles (SEPs), and their
variability within and beyond the 11-year solar cycle, make an important contribution to …

During extraordinary space weather, cosmic radiation can be significant enough to pose a
threat to aircrew health. Traditional methods of reducing massive cosmic radiation exposure …

On 10 September 2017, a ground level enhancement (GLE) of cosmic ray intensity,
identified as GLE72, was recorded by several stations of the worldwide neutron monitor …

The main data have been summarized, and the results, achieved using data from the
worldwide network during the entire period of ground-based observations of solar cosmic …

Abstract On 2017 September 10 Neutron Monitors (NMs) apparatus located at ground level
and high latitudes detected an increase in the counting rate associated to solar energetic …

Earth's magnetic field usually occurred due to abnormal conditions in the interplanetary
magnetic field (IMF) and solar wind plasma emissions caused by various solar …

We have carried out this work to clarify the possible mechanisms of two important high-
energy particle events (GLE69 2005 January 20, 06: 46 UT and GLE70 2006 December 13 …

With the goal of understanding the initiations of solar energetic particle (SEP)(MeV) and
ground-level enhancement (GLE)(GeV) particles, we have studied relative timings at …
