The planetary Kp index is one of the main indicators used to monitor geomagnetic activity. The official Kp index is reported only at 3 hour intervals, making it difficult to resolve rapid changes in geomagnetic activity driven by solar wind variability. In this work, we present a machine learning model developed to estimate the Kp index with a temporal resolution of one minute using...

Radial diffusion is a key process controlling the dynamics of relativistic electrons in planetary radiation belts. In Earth’s outer belt, the radial diffusion coefficient (Dll) is typically derived from well-established analytical formulations that relate electromagnetic field fluctuations, particularly ultra-low frequency (ULF) waves, to stochastic radial transport. For Saturn, by contrast,...

The variation of electron flux in the energy range from 0.015 to 51.768 keV is analyzed in association with the occurrence of plasmaspheric plumes under different solar wind conditions. During the formation of these structures, regions of enhanced plasma density extend to higher L-shell values, allowing the propagation of whistler-plume waves.
