Description
CSES-01 (China Seismo-Electromagnetic Satellite) is the first element of an
extended constellation of LEO (Low Earth Orbit) satellites, dedicated to monitoring
perturbations of electromagnetic fields, plasma and charged particle fluxes induced
by natural sources and artificial emitters in the near-Earth space. One of the eight
payloads on board CSES-01 is the Italian High-Energy Particle Detector (HEPD),
which is equipped with a silicon tracker and a range calorimeter to detect electrons
(3-100 MeV), protons (30-250 MeV), and light nuclei. Since the launch of CSES-01
in February 2018, HEPD has already returned valuable information about variations
in the Earth-Sun interaction during geomagnetic-storm transients. One of such events
was the G3-class geomagnetic storm that impacted the Earth’s magnetosphere in late
August 2018, causing a temporary rearrangement of the charged particle environment
around the planet. In this work, the HEPD response to this magnetospheric
disturbance is presented on the base of electron rate variation measurements in the
outer Van Allen radiation belts. The study of such events is crucial to better
understand mechanisms taking place during solar events and to prevent their harmful
effects on technological and anthropic systems, as well as on human health. The
presented results confirm the HEPD capabilities in monitoring the near-Earth
environment and contributing to establish a nowcasting/forecasting network in the
nearest possible future.
