Extreme dominance of Earth-origin heavy ions in the intense #RingCurrent near the Earth during the May 2024 super #GeomagneticStorm: #ionosphere supplied vast majority of ring current ions during May 2024 super geomagnetic storm, study finds: https://en.nagoya-u.ac.jp/news/articles/earths-ionosphere-supplied-vast-majority-of-ring-current-ions-during-may-2024-super-geomagnetic-storm-study-finds/ - despite the dense solar wind, solar wind ion contributions to the ring current during the May 2024 superstorm were minimal; the first simultaneous observation of ring current ions and solar wind during a storm this large.
