Schumann Resonance Frequency Increase Following Recurrent Solar Wind Stream Onsets
Earth and Space Science, Volume 13, Issue 10, October 2026.Abstract Recurrent high‐speed streams and corotating interaction regions (HSS/CIRs) are common solar‐wind drivers, but their influence on Schumann resonance (SR) frequencies remains poorly quantified. We analyzed 173 threshold‐defined HSS/CIR proxy onsets using superposed epoch composites, bootstrap uncertainty, and a month‐matched random‐epoch null ...

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.Abstract This study examines the equatorial ionospheric response over the South American sector during the onset of the extreme 2024 Mother's Day geomagnetic storm, which began at ∼17 UT on 10 May and reached the G5 level. Pronounced disturbances in ionospheric electrodynamics were observed under both daytime and nighttime conditions. Variations in the

Solar flare prediction models typically use classification, predicting only the probability of categorized events within a time window. This misses critical information, such as how many flares occur, their precise timings, and their intensities.

Features of Ground Level Enhancement (GLE #74) Event on 11 May 2024
Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.Abstract Ground Level Enhancement (GLE #74) occurred on 11 May 2024 following an X5.8 solar flare from active region AR 13668 and the associated halo coronal mass ejection. The event was observed by both ground‐based neutron monitors (NMs) and space‐borne instruments and occurred during a deep Forbush decrease and one of the strongest geomagnetic ...
