Earth's Alfvén wings driven by the April 2023 Coronal Mass Ejection

L Chen, D Gershman, B Burkholder… - Geophysical …, 2024 - Wiley Online Library
We report a rare regime of Earth's magnetosphere interaction with sub‐Alfvénic solar wind in
which the windsock‐like magnetosphere transforms into one with Alfvén wings. In the …

Global observations of geomagnetically induced currents caused by an extremely intense density pulse during a coronal mass ejection

TZ Liu, X Shi, MD Hartinger, V Angelopoulos… - Space …, 2024 - Wiley Online Library
A variety of magnetosphere‐ionosphere current systems and waves have been linked to
geomagnetic disturbance (GMD) and geomagnetically induced currents (GIC). However …

The Structure and Kinetic Ion Behavior of Low Mach Number Shocks
