EVIDENCE OF THE EARTH’S INNER RADIATION BELTS DURING THE LOW SOLAR AND GEOMAGNETIC ACTIVITY OBTAINED WITH THE STEP-F INSTRUMENT [PDF]
Radio Physics and Radio Astronomy, 2021 Purpose: The subject of research is the spatio-temporal charged particles in the Earth’s magnetosphere outside the South Atlantic magnetic Anomaly during the 11-year cycle of solar activity minimum.

The Astrophysical Journal, 2009 The magnetic field of the solar corona has a large-scale dipole character, which maps into the bipolar field in the solar wind. Using standard representations of the coronal field, we show that high-energy ions can be trapped stably in these large-scale closed fields.

Radial Transport in the Earth’s Radiation Belts: Linear, Quasi-linear, and Higher-order Processes
The Astrophysical Journal Supplement Series, 2023 Observational studies of the Earth’s radiation belts indicate that Alfvénic fluctuations in the frequency range of 2–25 mHz accelerate electrons to relativistic energies.

Reconstruction of the Radiation Belts for Solar Cycles 17–24 (1933–2017)
Space Weather, 2021 We present a reconstruction of the dynamics of the radiation belts from solar cycles 17 to 24 which allows us to study how radiation belt activity has varied between the different solar cycles.

OMEP-EOR: A MeV proton flux specification model for electric orbit raising missions
Journal of Space Weather and Space Climate, 2021 Electric Orbit Raising (EOR) for telecommunication satellites significantly reduced on-board fuel mass at the price of extended transfer durations. These relatively long transfers, which usually span a few months, cross large spans of the radiation belts,

NARX Neural Network Derivations of the Outer Boundary Radiation Belt Electron Flux
Space Weather, 2022 We present two new empirical models of radiation belt electron flux at geostationary orbit. GOES‐15 measurements of 0.8 MeV electrons were used to train a Nonlinear Autoregressive with Exogenous input (NARX) neural network for both modeling GOES‐15 flux ...

Using MEPED observations to infer plasma density and chorus intensity in the radiation belts
Frontiers in Astronomy and Space Sciences, 2022 Efforts to model and predict energetic electron fluxes in the radiation belts are highly sensitive to local wave-particle interactions. In this study, we use multi-point measurements of precipitating and trapped electron fluxes to investigate the dynamic

Space weather effects on the MAGION-4 and MAGION-5 solar cells [PDF]
Annales Geophysicae, 2005 Data on solar array efficiency measured on board two Czech MAGION micro-satellites between August 1995 and June 2002, during the period of increasing and high solar activity, were used to study the space weather effects on photo-voltaic solar cells. A
