Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract Bouncing packets are quasi‐periodic microbursts separated by the electron bounce period. Solar Anomalous and Magnetospheric Particle Explorer observations revealed relativistic (>1 MeV) inner‐belt bouncing packets with “crown,” “decaying,” and “flat” envelopes.

Evolution of Reversed Electron Energy Spectra in Earth’s Radiation Belts Observed by CIRBE
Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract Following an intense geomagnetic storm (Dst < −150 nT) on 5 November 2023, electron fluxes in the outer radiation belt were reduced by more than three orders of magnitude at energies below ∼700 keV while they were enhanced at ∼1–3 MeV, leading to reversed energy spectra.
