- Project Leader: Крякунова О.Н., к.ф.-м.н.
- Project goal: Development of a model for the behavior of the fluence of high-energy electrons with energy >> 2 MeV in geostationary orbit for different levels of solar activity and determination of the main patterns of behavior of various parameters of near-Earth and interplanetary medium during electron enhancements, depending on solar sources.
Project Tasks
Method for achieving the project objective: comprehensive studies of the behavior of high-energy magnetospheric electrons with energies >2 MeV, the intensity of galactic cosmic rays, and interplanetary medium parameters, based on solving logically interconnected, sequential tasks:
Task 1 (2023) – Investigate the averaged behavior of high-energy magnetospheric electrons and parameters of the near-Earth and interplanetary medium during periods of electron enhancements caused by various types of solar sources.
Task 2 (2024) – To study the diurnal variation of the flux of magnetospheric electrons with energy >2 MeV at geostationary orbit.
Task 3 (2025) – Develop a model for the behavior of the fluence of high-energy magnetospheric electrons with energy >2 MeV at geostationary orbit for various levels of solar activity.
Expected results
2023: Averaged behavior of high-energy magnetospheric electrons and parameters of the interplanetary and near-Earth medium during periods of electron enhancements caused by various types of solar sources.
2024: Peculiarities of diurnal variation in the flux of magnetospheric electrons with energy >2 MeV at geostationary orbit.
2025: A fluence behavior model for high-energy magnetospheric electrons with energy >2 MeV at geostationary orbit for various levels of solar activity.
Results Obtained
2023: The average behavior of high-energy magnetospheric electrons and parameters of the interplanetary and near-Earth environment during electron enhancements caused by high-speed solar wind streams from coronal holes and by coronal mass ejections was calculated.
2024: The specific features of the diurnal variation of the magnetospheric electron flux with energies >2 MeV at geostationary orbit from different solar sources were identified.
2025: A model was developed to describe the behavior of the fluence of high-energy magnetospheric electrons with energies >2 MeV at geostationary orbit for different levels of solar.
