“…The payload is optimized to measure electrons in the 3-100 MeV energy range, and protons between ∼40 and 250 MeV, as well as light nuclei with a ±60°field of view and a geometrical acceptance of more than 400 cm 2 sr. The HEPD-01 capabilities for galactic and trapped protons and space weather studies have already been assessed in Bartocci et al (2020), Martucci et al (2022), Palma et al 2021, andin Piersanti et al (2022). More technical details on the mission and the instrument itself can be found in previous publications (Picozza et al 2019;Ambrosi et al 2020;Sotgiu et al 2020;Ambrosi et al 2021).…”

Time-dependent energy spectra of galactic cosmic rays (GCRs) carry crucial information regarding their origin and propagation throughout the interstellar environment. When observed at the Earth, after traversing the interplanetary medium, such spectra are heavily affected by the solar wind and the embedded solar magnetic field permeating the inner sectors of the heliosphere. The activity of the Sun changes significantly over an 11 yr solar cycle—and so does the effect on cosmic particles; this translates into a phenomenon called solar modulation. Moreover, GCR spectra during different epochs of solar activity provide invaluable information for a complete understanding of the plethora of mechanisms taking place in various layers of the Sun’s atmosphere and how they evolve over time. The High-Energy Particle Detector (HEPD-01) has been continuously collecting data since 2018 August, during the quiet phase between solar cycles 24 and 25; the activity of the Sun is slowly but steadily rising and is expected to peak around 2025/2026. In this paper, we present the first spectra for ∼50–250 MeV galactic protons measured by the HEPD-01 instrument—placed on board the CSES-01 satellite—from 2018 August to 2022 March over a one-Carrington-rotation time basis. Such data are compared to the ones from other spaceborne experiments, present (e.g., EPHIN, Parker Solar Probe) and past (PAMELA), and to a state-of-the-art three-dimensional model describing the GCRs propagation through the heliosphere.

“…Panels (c and d) in Figure 6 contain MEPED fluxes over the >0.65 MeV range and the rate of >4.5 MeV particles detected by HEPD‐01,respectively. At L shells typical of the ORB, a persistent depletion starts right after the onset of the main phase, with no short‐term flux recovery to pre‐storm levels (Palma et al., 2021, and reference therein). These ORB losses in the relativistic range may be consistent with magnetopause shadowing (Herrera et al., 2016) and outward radial transport, as suggested by a deep incursion of the magnetopause, as estimated from the Shue et al.…”

(2021) for the 26 August 2018 geomagnetic storm, using particle data from the MEPED‐90° electron telescope on board the NOAA19‐POES satellite (Evans & Greer, 2004) and the High‐Energy Particle Detector (HEPD‐01) on board the CSES satellite (Picozza et al., 2019). The NOAA19‐POES is Sun‐synchronous nearly‐polar satellite orbiting at LEO altitudes.…”

<p>On May 12,&#160; 2021 the interplanetary counterpart of the May 9,&#160; 2021 coronal mass ejection impacted the Earth&#8217;s magnetosphere, giving rise to a strong geomagnetic storm.&#160; This work discusses the evolution of the various events linking the solar activity to the Earth&#8217;s ionosphere with special focus on the effects observed in the circumterrestrial environment. We investigate the propagation of the interplanetary coronal mass ejection and its interaction with the magnetosphere - ionosphere system in terms of both magnetospheric current systems and particle redistribution, by jointly analysing data from interplanetary, magnetospheric, and low Earth orbiting satellites. The principal magnetospheric current system activated during the different phases of the geomagnetic storm is correctly identified through the&#160; direct&#160; comparison&#160; between&#160; geosynchronous&#160; orbit&#160; observations&#160; and&#160; model&#160; predictions. From the particle point of view, we have found that the primary impact of the storm development is a net and rapid loss of relativistic electrons from the entire outer radiation belt. Our analysis shows no evidence for any short-term recovery to pre-storm levels during the days following the main phase.&#160; Storm effects also included a small Forbush decrease driven by the interplay between the interplanetary shock and subsequent magnetic cloud arrival.</p>
