Electrodynamic and Ionospheric Puzzles of the 10–11 May 2024 Geomagnetic Superstorm
Journal of Geophysical Research: Space Physics, Volume 130, Issue 5, May 2025.Abstract On 10 May 2024, a powerful coronal mass ejection arrived at Earth at 17:05UT and caused a major geomagnetic storm. With the minimum SYM‐H excursion of −497 nT (5‐min data), this storm is the largest geomagnetic disturbance since March 1989, and can be categorized as a superstorm. In this work, by using ground‐based and space‐borne instruments,
