Geomagnetically Induced Currents (GICs) are currents generated in power grids and other long conductive structures during geomagnetic storms. Rooted in Faraday’s law of induction, these currents arise from time-varying magnetic fields that induce electric fields in the ground. While GICs are a well-known space weather hazard, their behavior is complex …

The discovery that bursts of radio emission detected with simple antennas in a field were correlated with Io’s position around Jupiter gave the first indication of a moon magnetosphere interaction. Since these early hints at Io, there have been flybys of several moons in different magnetospheres revealing a range of …

Cold plasma constitutes a major mass source in Earth’s magnetosphere, originating primarily from the solar wind and the ionosphere. During geomagnetic storms, the ionospheric contribution can rise significantly. Understanding the transport pathways of cold plasma into the magnetosphere is, therefore, essential. One such pathway is plasmasphere refilling, a process wherein …

Energetic electron precipitation can significantly affect Earth’s atmospheric chemistry by generating ozone-depleting NOx and HOx compounds. Accurately monitoring these precipitation events is crucial for understanding their drivers and for assessing their potential atmospheric impacts. In this talk, I present high-resolution measurements of energetic electron precipitation (EEP) captured by a novel …
